FROM THE EDITOR Congratulations! The All Blacks have won the Rugby World Cup

against France and proved to be number one in the world of

rugby. However, when those two nations face off in the arena

of productivity, the Frenchmen clearly outperform the Kiwis. In

an address to the Electro-Technical Association Conference in

August ETITO CEO Garry Fissenden referred to France as “a

nation that is highly productive in terms of GDP per capita per

hour worked,” while “New Zealanders are the least productive

per hour worked,” when compared to numerous other OECD

countries. The first thought that comes to mind might be that

Kiwis just have to put in more hours. But it’s not that easy. In

his article on page 23, Antony Gollan, ETITO Communications

Adviser, points out that it is a lack of skills that holds NZ back,

not laziness, and he tells us why he considers industry training to

be an appropriate means to meet our productivity challenges. In

this issue’s Training 2012 feature you can also read the interesting

story of how Genesis Energy and Singer are teaming up to

equip apprentices for successfully coping with manufacturing

environments in the electrical industry that have become

increasingly demanding and technology dominated.

Training our workforce is one possibility to fill prosperity-

threatening skill gaps; another way is to attract talented individuals

from overseas. Consequently, Immigration NZ’s Skilled Migrant

Category made it possible for me to come to Aotearoa and

take over the editor’s seat of Electrical Technology. I might be

quite new to this country, but I pride myself on not being a

rookie to this line of work – back in Germany I used to write

technical articles for various companies and also edit a couple

of magazines on automation technology.

Our Special Feature retraces the successful story of another

skilled “immigrant” from Germany and its journey from Wester-

wald to Christchurch: starting on page 10 you can find out

how Rittal’s Data Centre Container ended up housing Orion

New Zealand Ltd’s infrastructure for business computing and

control of Christchurch’s power network.

Mainzeal and Siemens are delighted a total focus on safety has been recognised with two Transpower STAR awards for their work on Transpower’s High Voltage Direct Current (HVDC) Pole 3 project to increase the capacity of the interisland flow of power in New Zealand. The two companies are partners on the $672 million project to replace the 46-year-old Pole 1 equipment at Transpower’s substations at Haywards, in Upper Hutt near Wellington, and Benmore in the South Island. The main build phase is nearing completion with an impeccable health and safety record to date. The Mainzeal, Siemens and Transpower project team received the Best Safety Innovation award for solutions to several issues posed by the challenging surroundings, and the Top Site award for Benmore.

There were 110 nominations for the inaugural STAR awards’ seven categories, which recognise safety excellence among the companies and individuals who work on Transpower’s national grid high voltage transmission system. Mainzeal CEO Peter Gomm says he is immensely proud of the safety emphasis and innovations demonstrated by the project team: “The judges said all aspects of safety

Mainzeal and Siemens net STAR awards for focus on safety in challenging environments

are anticipated and addressed, with facilities and practices of exception-ally high standard.”

Peter Gomm continues, “This partnership with Siemens and Transpower has been built on similar company cultures. We are all leaders in our field and equally emphatic on the need for our workers to be as safe as possible during the project. It’s obvious from the pride taken at the two locations there has been a total safety buy-in from managers and site workers.” Peter Gomm says he understood from first-hand discussions how dif-ficult working conditions had been, and continued to be. “In the face of this, the HVDC team has achieved and set a new safety benchmark for Mainzeal and provided lessons which will be adapted across the company.”

Paul Ravlich, CEO of Siemens New Zealand, says the company is acutely aware its workers on the project often operate in situations which could be dangerous without correct procedures: “The health and safety of our team members has the highest possible priority at Siemens, and we are delighted to have the awards recognise the excellence achieved on this project.” Mr Ravlich says the initiatives from the project

team at Benmore which led to the ‘Best Safety Innovation’ Award show the calibre and dedication of those working on the project.

“The sheer isolation prompted the team to install a fully-equipped first aid room. It can be incred-ibly hot in inland Canterbury in midsummer, so they put precautions in place to help workers avoid and deal with heat stress,” Mr Ravlich says. These included providing cool showers and drink bottles contain-ing electrolytes. The innovative regime included extra monitoring of workers for signs of heat stress and extra breaks when temperatures got above 30ºC. Mr Gomm says

Rockwell Automation received the prestigious 2011 Frost and Sullivan Company of the Year Award for the Programmable Logic Controller in the South Pacific and South East Asia region. The award recognises the leading role Rockwell Automation has played in

developing cost-effective technology solutions with improved safety for programmable logic controllers (PLCs). It also confirms the commitment Rockwell Automation has made to the industry and the company’s position as a major participant in automation systems across many industries.

To qualify for the award, a company is measured on five key criteria: market share position, growth implementation, degree of in-novation with products and technologies, gain in market share and leadership in customer value. Rockwell Automation scored consistently high in all five categories for the South East Asia, Australian and New Zealand region.

“Rockwell Automation winning this award

confirms that the company’s customer value strategies are recognised by the automation industry, and in turn by the broader market,” said Twain Drewett, managing director Rockwell Automation Australia and New Zealand. “The PLC is continuing to evolve into a product that meets the customer’s requirements for plant-wide optimisation and sustainable production, while simultane-ously helping to converge the IT arena into the manufacturing space. This value-add of Rockwell Automation Customer Services and Solutions and the strength of our network of partners has provided the PLC with ‘Best in Class’ differentiation,” concluded Drewett.

the project team recognised the need to establish a hazardous goods storage area at both Benmore and Haywards and undertake appropri-ate training. They initiated a “yellow card” system to easily report hazards and near-misses around the construction site at Haywards, and established a number of safety stations as a one-stop shop for safety information and equipment. “The judges said the project team provides an exemplar of safety leadership, second to none, which they should be rightly proud of.”

“Our customers love the choice, and they love the service.”

For RS Components, all signs point to growth. Stefan Richter talked to Jeremy Edwards about the company’s recipe for success and their market strategy for the ANZ region.

ET: The financial year 2010/2011 was a very successful one for RS Components. And your company just announced a strong first half of the current financial year. What’s the secret to your success?J. Edwards: In fact for the financial year that ended 31 March 2011 sales was in excess of £ 1 billion for the first time in RS Components’ history. As for the ANZ region, we experienced the biggest year by turnover. And this growth is going to continue over the present financial year.

ET: And the secret…J. Edwards: The secret to our success is the fact that we understand our customers’ needs, and the customers are increasingly rewarding our approach. RS Components is a broad-range high-level service distributor of electronics and maintenance products. Our customers just love the choice of products we have to offer, and they love the service they get. RS Components’ business model focuses on speed of delivery and ease of selection, ordering and purchase.

ET: Let’s suppose I ordered a product today. When can I expect to receive the parcel?J. Edwards: Our products are available on demand, in store and in stock, so our customers save significantly on the traditional downtime experienced between ordering products and waiting for delivery. Our supply chain reaches 95 percent of Australia by next day, and the same applies to our customers in New Zealand. If you visit our Auckland-based Trade Counter, in Penrose, you can choose

from over 65,000 products. In that case, your needs are met the same day.

ET: Your company’s e-commerce sales account for more than 50 percent of the overall revenue. Is there a future for the showrooms and warehouses you have across Australia and in Auckland?J. Edwards: That’s right, the online business has become an important pillar, and RS Components have just recently completed a number of significant enhancements to our websites, making the process of finding products clearer, faster and easier. But we are definitely not only investing in e-commerce. Earlier this year we opened a showroom in Brisbane, and we are planning on upgrading further showrooms in the ANZ region. We see warehouses and showrooms as key element to our multi-channel sales and distribu-tion strategy.

ET: What is the customers’ response to the Brisbane showroom?J. Edwards: The showroom has one of the largest stockholdings of automation and manu-facturing control components in Australia and New Zealand and in its first month of opening generated a 56 percent increase on the previ-ous month’s sales for the region. The products we offer are widely used in various growth industries like mining, oil and gas, process manufacturing, transportation and panel build-ing industries. The Queensland showroom maintains the RS Components commitment to high availability and product readiness that we have become known for in Australia and NZ over the last 35 years. The bottom line is: our customers are voting with their dollars, and the turnover generated – both online and offline – proves our strategy to be in line with our customers’ needs.

ET: You mentioned ease of selection, ordering and purchase as one important focus of your business activities. Could you expand on that topic?J. Edwards: When you put yourself in the shoes of a maintenance engineer, for example, what do you expect from your electronics distributor? You want to get the right product in your hand asap to fix your problem. And you want it to happen with the least possible amount of hassle. We understand that and offer our clients a helping hand wherever we can. We created our websites to be an information-rich environment, with over one million documents online for the customer to view, such as instructions, manuals, data sheets, and material safety sheets. We try to ensure our clients get all the information they need to evaluate and select the optimal product for their application.If there are still questions to be answered, the customer can talk to our dedicated and technically experienced help team, operating from Sydney. And, of course, the experienced and friendly staff in our showrooms are also looking forward to helping their customers. When it comes to delivery and payment, there are no nasty surprises in the form of incorrect invoices or partly deliveries. The customer knows exactly what he gets, when he gets it and how much he has to pay for it. As I said, we take the hassle away, and the engineer can fully concentrate on his real work.

ET: How many products are available to custom-ers in New Zealand?J. Edwards: In addition to the print version of our product catalogue, consisting of 70,000 products, we offer on our websites an extensive range of 550,000 products from leading global and local manufacturers. The 2011 catalogue is also now available in a new digital format on a USB memory stick offering 150,000 products, providing engineers with a more efficient way to review, select and procure. All products featured in the catalogues and online are in stock in Asia-Pacific and available for immediate delivery. As far as automation and control technology is concerned, we stock about 15,000 products from leading brands such as Schneider Electric, ABB, Siemens, SMC, Omron and Phoenix Contact.

ET: Jeremy, thank you very much for the interview.

“The secret to our success is the fact that we understand our customer’s needs.” – Jeremy Edwards, Country Manager Australia and New Zealand, RS Components

Boosting productivity with lighting technology

Sensors that follow workers’ movements, lights that monitor and adjust to natural sunlight levels, and dynamic walls of colour are just some of the new technologies that are now available to New Zealand workplaces. These new technologies bring threefold benefits: significant energy and cost savings, new tools for design professionals to create innovative and creative spaces, and improvements in the health and wellbeing of workers, which in turn improves productivity and morale.(i)

Lighting makes up 40 percent of the energy used in offices and new lighting technology can bring significant energy savings. Philips has found on projects in Germany and the United Kingdom that lighting energy savings of up to 70 percent can be made when energy-efficient lighting is combined with systems that recognise light levels outside and identify when individuals are working in a space and adjust the interior lighting accordingly. Philips recently partnered with ceiling tile manufac-turer Armstrong to develop ceiling panels with built-in energy efficient lighting. These panels are significantly thinner than regular lighting installed in ceiling panels, enabling greater ceil-ing heights – particularly useful when older buildings are being retrofitted to achieve Green Star ratings.

An international partnership with Kvadrat Soft Cells has developed innovative luminous textiles by integrating Philips LEDs into Kvadrat’s acoustic panels, giving architects, interior designers and lighting specialists new freedom to enhance

workplaces with texture and light. “With these new developments and tools we have begun to see companies embracing quality lighting in workplaces, acknowledging the significant effect it has not just financially and environmentally but also on staff wellbeing,” says David Procter, Marketing Manager, Philips Lighting.

“Our research(ii) has shown that investing in workplace lighting can contribute to greater employee well-being and performance, as well as reducing employee stress, absentee-ism and industrial accidents,” he said. A study commissioned by Philips and undertaken by City University London’s Center for Performance for Work emphasised the importance of lighting to worker productivity, something also illustrated in the 2006 paper by the New Zealand Parliamentary Commissioner for the Environment, which found that improved lighting design increased worker productivity by up to 23 percent.(iii)

Driving around the world on solar power

Electric motors turn the cogs of industry – but these days they are turning other wheels as well. Global issues with fossil fuel effect-and-supply are finally beginning to power up a serious electric car movement. SEW-Eurodrive NZ is a company that takes electric motors very seriously, providing NZ custom-ers with a comprehensive range of modular electric motor and controller, power, size and drive configurations backed by around-the-clock technical support. SEW-Eurodrive NZ is proud to assist with the Bochum Univer-sity team’s attempt to make the first ever circumnavigation of the globe in an autonomously solar-powered car.

The NZ section of this journey will begin on 24th November from Auckland and, accompanied by electric car expert Mike Duke and a small team of students

from Waikato University with their own experimental electric car, they will proceed down SH1, hopefully arriving at Bluff around 9th December. On reaching Christchurch the ensemble will be joined by the “made in Christchurch” Team SolarFern vehicle. At Bluff the Bochum car will be packed up for shipment to the USA and the next part of its year-long adventure, meanwhile Team SolarFern will turn back northbound for Cape Reinga – an estimated journey of six days. They will attempt the Wellington-to-Auckland section in a single day – theoretically possible given good weather. This unprecedented flurry of solar/electric activity on SH1 should provide the NZ motoring public with some food for thought.

SolarFern was created by a small group of private enthusiasts and raced in the 2007 World So-

lar challenge with the distinction of sporting the oldest solar array in the event, having borrowed solar panels from the Hamilton-built 1993 Solar Kiwi car. This was their “plan B” solution, activated when anticipated sponsorship funding for a state-of-the-art commercial silicon array being specially built for them was withdrawn at the last minute. In true Kiwi fashion, even with this handicap, they outperformed many well-financed teams who were using much more powerful new solar arrays.

Bochum University of Applied Sciences has a history of building and racing solar cars dating back to 1999, beginning with a combined student project under-taken with Southbank University in London. At this point a future connection to NZ was formed as Mike Duke, then working on the project for Southbank, later moved to Waikato University in Hamilton bringing with him a wealth of talent, international experience and passion for the topic.

In 2001 the first German solar car Mad Dog III was solely constructed by German students in London and participated in the epic World Solar Challenge (WSC) event run across the Australian continent from Darwin to Adelaide. Between 2001 and 2003 Bochum developed a new car called Hans Go! that placed fifth in the 2003 WSC, also winning the Technical Innovation Award presented by Australia’s Commonwealth Scientific and Industrial Research Organisation for their implemented telemetry system. They placed eighth in the 2005 WSC.

Next came what they like to call “The most beautiful solar car in the world” – Solarworld-1, which was planned and built from 2005 to 2007. They placed fourth in the 2007 WSC and were awarded Best Design. In 2008 they came third in the North American Solar Chal-lenge and received award for innovation and excellence in the

fields of mechanics and electrical engineering. When not on the road in Australia or America, the most beautiful car in the world resides at the University of Applied Sciences Bochum, on display as a proud inspiration to others.

In 2009 a new vehicle, the BOcruiser was made for the World Solar Challenge. Built with typical street-car dimen-sions and not designed as a race car, though still employing fibre-reinforced composites, high-strength aluminium with newly developed wheel-hub motors, this “sun chariot” brought practi-cal solar transport a step closer to everyday life.

Now Bochum’s latest, even more ambitious, more conventional-looking two door, two seater, public-friendly and solar-powered vehicle will soon be seen on NZ highways as part of its journey around the globe starting from Darwin with the 2011 WSC fleet on the 16th of October. Named SolarWorld Gran Turismo (SolarWorld GT) the car is facing a road journey of some 34,000km and two equatorial crossings to fulfil the official circumnavigation requirements for a place in the Guinness Book of World Records and gain a significant place in transport history. They hope that their example will transform the prevailing public perception of solar/electric cars from merely a motorsport oddity into a vision of achievable, potentially affordable and environmentally preferable personal transport reality.

Essential factors of success in the Bochum project are the integrated interdisciplinary teamwork approach within the University, a great passion for what they are working on, and the continued support of their international sponsors such as SEW-Eurodrive.

BUSINESS PROFILE

HLG power solutions from Mean Well are not only suitable for LED lighting. Thanks to their high IP level they also succeed in harsh-environment applications.

Mean Well’s HLG family of power solutions is well-known in the LED lighting industry for its excellent performance with regard to its efficiency, operating temperature, lifetime and waterproof feature. It won the “Taiwan Excellence” award in 2011 and found favour with many of Mean Well’s customers in the lighting business.

The numerous success stories that have been achieved in LED applications make it easy for people to forget that HLG is actually also a promising power solution for applica-tions in harsh environments. Certificated with EN 60950, the HLG series provides output power from 40W to 320W, world-wide range AC input, and complete output voltage coverage (11V to 57V). The units can operate at 60 degrees Celsius, still with full output. Moreover, the IP67 design with metal case makes them outdoor applicable. With all the features that are included, a superb 95 percent efficiency and five years warranty, the HLG series distinguishes itself among other contemporary industrial power supplies in the market.

Here are some remarkable applications Mean Well have done using HLG power so-lutions in consumer and industrial products:

Application 1: Climate systemTarget spec: 320W, HTHH*1, fan-less, and five-year warranty Model: HLG-320Modification: Input/output connectors, circuit modified for EN 60335

One of Mean Well’s customers was develop-ing an ecology-friendly air conditioner. Inside their air conditioner, a 300W power supply

Industrial power supplies make a mark in demanding applications

was required which could operate in an ambient temperature around 50 degrees Celsius with medium to high humidity levels. As this product belongs in the class of household electrical appliances it was required to pass EN 60335 safety require-ments.

In their designing phase, the first power solution this customer thought of was using an USP-like U type power supply which would have required them to design an additional container box for the heat transferring and safety insulation level of the power supply. After Mean Well’s HLG series was introduced to them, they quickly realised that HLG was perfect for their application for several reasons:

1) The power supply is fan-less, a fact that constituted an overall prerequisite.

2) Only little consideration had to be given to the thermal dissipation.

3) The product is completely protected, therefore no extra protection box is needed.

4) The power solution’s high efficiency meets the customer’s brand image for green products.

5) The HGL series comes with a five-year warranty.

Mean Well has successfully designed the HLG-320 into the air conditioner and the customer is happy with the solution’s performance and also satisfied with Mean Well’s flexible design capability.

Application 2: Agricultural machine – battery chargingTarget spec: 150W to 240W, HTHH, outdoor use (Anti-UV), IP67Model: HLG-150-30, HLG-185-30, HLG-240-30Modification: max. Vo preset to 28V, input/output connectors

Another one of Mean Well’s key account customers are using the HLG-240 power supply as the battery charger for their lawn mower. In this application the charger is placed in a garden where a simple shielding is provided to protect the charger from di-rect immersion into water. Nonetheless, IP67 is still required for the outdoor environment.

For this customer Mean Well again recom-mended HLG because it offers IP67 with metal case, which is most suitable for applications in harsh environments like this. In addition to that, to reduce the customer’s design complexity, the company modified the input cable to 1.5 metre with a local AC plug, and the output cable with a M15 waterproof connector.

HLG Series: Product features• High efficiency (95 percent)• Metal case, IP67/IP65 design for indoor

or outdoor installations• Built-in active PFC function• Built-in 3-in-1 dimming function (1 to

10VDC, PWM signal or resistance) for B type

• five-year warranty

Mean Well is one of the leading switching power supply manufacturers in Taiwan. Established in 1982, the company gained ISO-9001 certification in 1994. Mean Well’s product lines include AC/DC switching power supplies, DC/DC converters, DC/AC inverters and battery chargers.

The Taiwanese manufacturer has over 4,000 standard models widely used in industrial and office automation, communication, LED light-ing, medical, and moving sign.

After the February earthquake in Christchurch, electricity provider Orion New Zealand Ltd started to look for a solution to protect their IT equipment from aftershocks. The quest finally ended in Herborn, close to the German Westerwald, where Rittal provided the perfect solution to keep Christchurch powered. Rittal’s data centre container now houses Orion’s infrastructure for business computing and control of the power network. Stefan Richter reports.

Around 193,000 homes and businesses in Central Canterbury obtain their electricity from Orion, the owner and operator of the greater Christchurch electricity distribution network. The power network, consisting of 13,600 kilometres of lines and cables, covers about 8,000 square kilometres – including Christchurch and Banks Peninsula as well as rural communities and highland areas. When the 6.3 magnitude earthquake hit Christ-

IT INFRASTRUCTURE

From Westerwald to Christchurch

church on 22 February 2011, the company’s office building in Manchester Street in Christchurch’s CBD was severely damaged, and the computer room containing Orion’s suite of network monitoring and control equipment partially sunk. However, the vital computer systems kept functioning and have not failed during subsequent aftershocks.

Shortly after the February quake Orion began an international search for a robust and portable solution to protect its IT equip-ment – and with it secure the city’s power supply. Finally the company commissioned Rittal, one of the world’s leading system suppliers for enclosures, power distribution, climate control, IT infrastructure and soft-ware, to supply a transportable data centre container with direct free cooling technology to house their IT equipment. “We looked at a number of other suppliers, and it came down to functionality, flexibility, support and suitability for our business applications as well as the energy saving from the free cool-ing feature,” reports Neville Digby, Senior

Systems Engineer, Orion New Zealand Limited. “It was also important to us that we chose a technology supplier we could trust.” Orion has already had good experiences with Rittal’s German-engineered solutions for data racks and power infrastructure in the existing facility. “We use Rittal racks in all our power substations as well as our data centres. Our main data centre also relied on Rittal water-cooled LCP units (closed rack cooling) and Rittal in rack fire suppression systems. Therefore the unit we ordered was a good fit,” says Neville Digby.

IT infrastructure in a robust containerRittal immediately star ted configuring the RDCC (Rittal Data Centre Container) unit. At the Rittal Headquarters in Herborn, in the Lahn-Dill region in Hessen, the German engineers integrated all IT infrastructures in the robust outdoor module, a custom built 10x3-metre container, so that there were no outer installations required. The RDCC, which weighs 15 tons, was pre-fabricated

and also pre-tested in Rittal’s data centre container facility in Germany.

Heeding the advice of a consultant, Orion deliberately chose to use Rittal ambient air DFC units (Direct Free Cooling with support-ing DX cooling during hot days). This modular cooling system has an output of 40 kW, re-duces the energy outlay by up to 40 percent as compared to conventional air conditioning units for data centres and ensures a lower PUE (power usage effectiveness) of approxi-mately 1.3. It uses filtered outside air to cool the data centre. The system works according to the cold aisle containment principle. Instead of flooding the data centre with cold air, the cold aisle containment system from Rittal effectively traps the cool air exactly where it is needed: directly in front of the air intake of the servers. Cold air is directed across the whole height of the enclosure, ensuring that there are no hotspots and the hot air is exhausted out of the system. Due to the cold aisle being contained, the hot exhaust air has no chance of mixing with the cold inlet air, therefore the system efficiency increases. Air circulation cooling units can be operated at an optimum thermal efficiency level.

Rittal’s mobile data centre features a fully-redundant UPS with two hours battery backup. This modular solution uses “double conversion” UPS technology according to the highest classification VFI-SS -111, providing a constant output irrespective of the incoming voltage, coupled with a high overall operating ratio and minimal space requirements. The PMC 40 (redundant design) also offers “safe swap” capabilities. The user can easily and safely exchange the module while the system is operational, without having to switch the UPS to bypass mode.

Power in the container’s racks is usu-ally distributed via Rittal’s PSM (Power System Module) rails. This modular solution significantly reduces cabling and assembly work, thanks to a vertical support rail with 3-phase infeed. The various insert modules can be snap-fitted into the support rail in any combination, even when the system is operational, because the support section is shock-hazard protected. The rails are available in 1-phase or 3-phase and with single, dual or quad infeed.

Also on the container’s feature list is a comprehensive web-based monitoring system (Rittal CMC TC, Computer Multi Control-Top Concept) to manage the data centre container and its integrated infrastructure. The CMC-TC package is specially designed according to the chosen system configuration. The customised package allows Orion to monitor the main technical components, such

as air-con, temperature, etc., and includes the possibility to automatically send status/alarm messages via Orion’s own IP-network.

All of the container’s data and power cables are managed in a 300mm high raised floor with heavy-duty rating. The weather- and fire-proof cable and pipe entry ducts ensure very high physical security. Rittal uses specially design contain-ers, not standard shipping containers, to make the units earthquake-protected. The Orion container is reinforced with welded steel for extra stability. The TS8 server racks inside are also secured to the roof and raised floor and are fitted with an earthquake kit. Rittal TS8 standard enclosures with mounting plates and a weight load of 150kg (installed on the

mounting plate) have received certification of their suitability for use up to Telcordia risk zone 3. The racks are currently undergoing additional testing to get them certified to zone 4 (zones with considerable earthquake activity).

Rittal’s engineers have also included a 2-in-1 early-warning fire alarm and extinguisher

system: the Novec1230 gas extinguishing system (DET-AC XL) with integrated early active smoke detection. The DET-AC XL is housed in a 300 x 2000 x 1000mm rack-type enclosure. The DET-AC XL is designed for open rack and room based extinguishing. Orion currently uses the 482.6 mm (19˝) rack mount, which only requires 1 U of space in their existing data centre. With the extin-guisher Novec 1230 integrated in a shallow tank, a volume of up to three m³ can be extinguished (closed rack application).

The container arrives in New ZealandOn Sunday, 10 July 2011, only a few weeks after the order reached Germany, the custom-built data centre was unloaded at the Christchurch’s Port of Lyttelton, which suffered earthquake damage but has resumed operations to ensure the safe flow of commodities and goods through the port and assist in the Christchurch rebuild. Via truck, the container reached its final destina-tion at the Orion site in Christchurch. Neville Digby’s comment: “Commissioning this facility in the next couple of weeks will be a major milestone for Orion and Rittal, and is the key to the network’s recovery after the earth-quakes. Rittal is nearing the end of a huge amount of work to get the data centre ready for operation here – they responded to our urgent request quickly and fast-tracked the manufacturing of the unit to deliver us a solution that fully meets our needs.”

A couple of months later Orion’s Senior Systems Engineer shares his experiences with the outdoor data centre from Germany: “Once the container arrived it became our main data centre for business computing and control of the power network and will continue to do so in the future.” Among the reasons why Orion chose Rittal’s solution

were its pre-fabricated and plug-and-play concept (only data and power cables are required to star t the RDCC), as well as its ability to be moved as required. On being asked how long it took to put the mobile data centre into operation after its delivery, Neville Digby replies, “This question is difficult to answer as we opted for it to leave Germany without the power switchboard and associated cables in place just to meet a particular sailing schedule. That resulted in more work having to be done on arrival. If a container arrived with all the wiring in place, and the site was ready for it as ours was, I guess it could be fully commissioned in under five working days, possibly in only three days.”

“Our mobile data centre now houses the sensitive computer systems that are important for operating and managing the power network in Christchurch and the vicinity,” comments Helmut Binder, Executive Vice President Sales Asia Pacific Middle East at Rittal. “The data centre container at Orion meets exactly the sort of requirements we assumed during its development. It can be used as an interim data centre during expan-sion or rebuilding work, for example, when space is limited in listed historical buildings or as an extension where capacity constraints exist. Large modern data centres also rely on the container modules, since they allow computing capacity to be scaled on demand, which increases utilisation.”

All expectations were metAll in all, Orion only had good things to say about the product and service provided by Rittal. “There is only one word, ‘superb’. Rittal’s solution is meeting all our expecta-tions and we see it as a very flexible business tool. Rittal have an extraordinary range of

products and options, and they know them so well. We were able to get a complete solution for our data centre infrastructure and security needs from one supplier – a much simpler, more time-efficient process that ensures all products work seamlessly together.” And what holds the future for the data centre? “We are seriously looking at embedding one in our future building or placing it besides the building. The current one would then go to our future DR site. The business case for doing this is compel-ling,” says Neville Digby and adds, “Many Australasian utility companies are following the project with interest. Orion has become a test case for installing a robust portable technology solution in the wake of a natural disaster, which can easily move if the com-pany needs to relocate to a new site.”

Another data centre container will soon come to New Zealand. The Red Cross/St. John in Wellington is also impressed by this solution and has ordered a container from Rittal. Peter McDowall, St John ICT Director, explains this decision. “St John selected Rittal’s solution for our infrastructure after a thorough and in-depth look at the market. The main benefit of the Rittal solution for St John is the ability to relocate the data centre as one unit in the event of another major disruptive event. St John have had a data centre in Christchurch for a number of years and although it continued to operate throughout the Christchurch earthquakes, we see the value in being able to respond to what is an ongoing changing environment. We will use the Rittal solution to house one of three data centres that support the activities of St John. We have placed an order and we expect delivery in mid to late January 2012.”

Does your meter measure up?Auckland and Wellington-based TransNet NZ now offer a complete package on customers’ test and measurement requirements. The company emphasizes the importance of knowing that test tools meet today’s tough standards and perform as they should. Here are some steps users can take to make sure their test tools measure up:

1) Look for independent testing and certification

Examine your test tools for proof that they have been tested and certified by two or more inde-pendent testing laboratories, such as Underwrit-ers Laboratories (UL) in the United States, CSA in Canada and TUV Product Service in Europe. This ensures that the tools have passed the most rigorous tests and meet every applicable standard.

2) Inspect the toolsTest tools must be visually inspected frequently to help detect damage and ensure proper operation. Look for problems such as a broken case, worn test leads or a faded display. Inspect the tool’s test leads and probes for frayed or broken wires.

Make sure they have: shrouded connectors, finger guards, CAT ratings that equal or exceed those of the meter, double insulation and a minimum of exposed metal on the probe tips. Use the meter’s own continuity testing function to check for internal breaks. To do that, first insert leads in V/Ω and COM inputs. Then select Ω and touch probe tips. Good leads are in the area of 0.1 to 0.3 Ω. This inspection alone may not detect all possible problems. More testing is needed.

3) Supplementary inspectionIn addition to your thorough visual inspection, check your tools for the following points:

• Look for the 1000-volt, CAT III or 600-volt, CAT IV rating on the front of meters and testers, and a “double insulated” symbol on the back.

• Check the instrument’s manual to verify that the ohms and continuity circuits are protected to the same level as the voltage test circuit.

• Make sure that the amperage and voltage of

meter fuses meets specifications. Fuse voltage must be as high as or higher than the meter’s voltage rating.

• Use the meter’s own test capability to ensure that the fuses are in place and working right. To do that, plug test lead in V/Ω input. Then select Ω. The second step consists in inserting the probe tip into the mA input. Read value. Finally you have to insert the probe tip into the A input. Read value. Typically a fuse in good condition should show a value of close to zero, but you should always check the meter’s manual for the specified reading. Part of the new regulations outline that test meters require calibration testing at regular intervals which TransNet can arrange.

Choosing the best available test tools is vital to helping protect yourself from possible injury or death. Tools that fail any of these inspections should be replaced with new test tools from a leading manufacturer. Replacing an outdated or worn test instrument is a small price to pay for the added protection and reassurance a new tool can provide.

New multi-function testers simplify testing

The latest Megger multi-function testers constitute a step up from the very popular MFT1500 Series. The new MFT1700/1800 models offer more safety, more functions and simplified testing. In addition to all the functionality offered by previous models, earth loop testing is now made easier with the new two-wire non-trip earth loop test feature. RCD testing is now faster and includes an auto RCD test function for applications where the test access point is separate from the RCD location. There is also an RCD ramp test which is ideal for nuisance tripping situations. Users do no longer need an additional earth tester in their arsenals as the MFT1825 & MFT1835 have two and three pole ground rod and

earth resistance testing functions. The optional earth testing kit is required for this function. The usual insulation testing, voltage and resistance ranges complete the feature list. The new MFT1700/1800 models are CATIV-safety rated with an IP54 dust and moisture ingress rating. The three models available will perform all the tests required by the latest electricity regulations and standards with the MFT1710 as the entry-level model, the popular MFT1825 and the top-of-the-range MFT1835. This model is True RMS, has rechargeable batteries and features results storage with easy Bluetooth download. • Go to www.electricaltechnology.co.nz/enquiry quote: E111114

The circuit mapper is the first device of its kind that maps up to 24 branch circuits of wiring systems concur-rently with a single transmitter and receiver. The transmitter connects to the branch lines at the panel, and the receiver displays the corresponding circuit number through digital signal processing, with or without direct electrical contact, so you know exactly which breaker is connected to each transmitter lead. This circuit mapper offers considerable advan-tages over traditional methods. It is labour-saving, eliminates downtime, protects sensitive electronic equipment, and the user can map the circuits on their own. There is also no more need to turn breakers on and off. Last but not least, circuits can be tested with or without power. The circuit mapper is available from

RBC MD Craig Keesing checks progress on a motor refurb.

MD of the local subsidiary of the CMG Engineering Group, Craig Keesing’s life has been turned upside down in recent months – and he is enjoying every moment as he and his newly-merged colleagues from two other companies gear up to move into a brand-spanking new HQ, warehouse and giant workshop a block away from their current Rosebank Road, Avondale premises.

And there is more to come, early in the second quarter of 2012, when the Regal Beliot Corporation

(RBC) USA giant completes its take over, CMG and another name you will recognise, FASCO – as part of the RBC deal CMG NZ has taken this under its wing, with the support of Argon Industries, the NZ Distributor and refrigeration experts, based in Penrose – plus OBA NZ, one of the leaders in insulation and conductor materials, become one integrated operation.

Just for good measure Keesing added another string to the already muscular bow with acquisitions of Rotational Power and South

Pacific Rewinds. “The acquisition of Rotational Power and South Pacific Rewinds, based in Otahuhu, expanded the capabilities of the group in the manufacturing, rewind/repair industry, with all sites implementing the EECA Telarc rewind quality code.

“The next step from there was the ‘electric motor replacement policy’. By now you would have seen this working well and we continue to follow through on this by visiting end-users to help reduce costs to plants,” he says.

“We have kept working with those customers who took advantage of the Motor Bounty scheme, to ensure they see the benefits. And we also see this as an area of our combined business which will continue to expand as New Zealand comes back from the global financial disaster and gets back on track,” Keesing says.

With the benefits of the merged operations taking effect through efficiencies and cost savings, in being in a single designed-to-spec Auckland site, Keesing believes the benefits from the sale of the company to Wisconsin-based Regal Beloit Corporation last year are enabling it to become a ‘one-stop shop for new motors, rewinds, onsite service and much more’. This enabled the company to focus on small and large-end users to support any situation; basically, if you have a motor problem they can sort it. The company has a solid reputation for specialist hazardous area equipment and refurbs in particular.

Regal Beloit is headquartered in Beloit, Wisconsin, and has manufacturing, sales, and service facilities throughout the United States, Canada, Mexico, Europe, Asia and now Australasia. Its common stock is a component of the S&P Mid Cap 400 Index and the Russell 2000 Index. “Regal Beloit Corporation has for some time now recognised the vast market potential of New Zealand and the many benefits of expanding into this country with significant agricultural, oil and gas, mining, pulp and paper industries, to name a few, became increasingly obvious,” Keesing says.

As impressive as that all is, Keesing is hard at it absorbing the American and global way of doing business and has already completed a couple of business courses en route to a residential one in the US later next year. He is focused on both integrating and consolidating the operations in the new premises, without impacting customers. In addition to the Auckland operation, the merged operation will also have outlets in Christchurch, Rotorua and Cambridge.

The new HQ complex includes a 10,000 square feet, ISO 9001 and Telarc code-of-practice certified workshop – with a Verissimo gantry system, capable of lifting 10 tonnes – and 12, 000 square feet of warehouse “to accommodate the largest range of new electric motors held in New Zealand” plus

a suite of offices for sales, customer services and management.

“The fit-out will consist of up-to-date equipment allowing our service shop to provide industry with the best possible work practice, as per the ECCA NZ-promoted Motor Rewind Workshop Quality code 2009.

“Given we will have an expert team of 13 qualified servicemen on the floor, no job will be too big, and when you add more than 250 years of experience in AC, DC motor repair, generators, gear boxes, plus on-site service; not to mention the only IANZ accredited work shop in ‘hazardous areas’, I reckon I can confidently say we can live up to any challenge in this field. No question.”

The move to RBC also brings additional mainstream brands in-cluding: VACON, Lesson, Marathon Electric, Genteq, Morrill Motors, DURST, Gove Gear, Hub City and Lincoln, to add to CMG, VARVEL and the previously mentioned FASCO. Keesing describes the consolidation and move as a $250,000 process. He is expecting large savings from consolidating all existing rentals into a single lease and the benefits of rationalising. He has no plans for cutting staff and is adopting a two-to-three year view when it comes to the economy.

“I’m not very optimistic about prospects in the New Zealand following the conclusion of the Rugby World Cup, and am not expecting things to get much better than they currently are for the next six to eight to 12 months. I expect conditions to be tough. We will meet our objectives, but almost certainly will not exceed them.

“However, that said, we are taking the view that we need to get our ducks in a row for two-to-three years time when we foresee things picking up again. In the meantime, we now have an expanded range of products and a variety of market niches which tend to move up and back counter-cyclically with each other, so we aren’t subjected to some of the all-or-nothing features that the industry can suffer from.

“We are looking to Oil and Gas and additional OEM opportunities with the FASCO range in the next

short while to boost sales and income,” he says.

The hazardous area motors’ opportunities, especially where dust is involved, are another potential growth area, he believes. “We have an established reputation in that area and it is one which a tightening of legislation and policing would grow more rapidly. While most large companies comply with regu-lations there are still some among them who do not, along with a number of smaller companies who take a “Why would we do it?” attitude against a background of very few enforcements of standards,” Keesing says.

The company is a follower of lean manufacturing, favouring the Lean Six Sigma (Black Belt and Green Belt) and the Kaizen approach, and he is taken with the cost savings and efficiencies they derive and the customer service benefits which virtually follow naturally from the management approach. And he is certain that the burgeoning relationships with colleagues in the RBC organisation will further enhance their efficien-cies in the years to come.

CMG was previously a leading Australian-owned supplier in the electric motor industry, which, in recent years, had established facilities in eight countries. The New Zealand subsidiary of CMG, in the experienced and capable hands of Keesing – who has spent 10.5 years with the company over the 12 years it operated in New Zealand, prior to acquisition by RBC – became one of the more respected and largest suppliers of the company’s wide range of electric motors.

The acquisition of shares from the Gringlas family, which had owned CMG since 1948, provided RBC with an ‘open door’ to this lucrative market through CMGEG’s already well-established New Zealand operation. The company had always prided itself in being ‘the one stop shop in the industry’, as a manufacturer of all types and sizes of electric motors, with the promise of ‘you can now have the right answer for the right price’.

“Our sales teams too had also established a reputation of being


able to come up with the right answers in this area, given their backgrounds in mechanical and electrical services, so the right motor or motor gearbox solution was only ever a phone call away for new or existing customers,” says Keesing. He is convinced the efforts CMG and now RBC put into product training and support will continue to provide that platform for continuing to deliver the ‘right answer for the right price’ and further enhance that via the vast RBC range, with its global support and product knowledge.

You get the feeling that the official launch day cannot come soon enough.

Great performance in the compact class

Process efficiency up, investment costs down – that is the formula for success of optimal machining processes. A key factor here is the shortening of cycle times. The DriveLine actuating drives from Siko make this possible. With its small size, the new AG05 actuating drive offers excellent power density for de-centralised positioning tasks. The automatic adjustment of formats, stops, tools and valves as well as many other comparable

positionings: The intelligent AG05 actuating drive easily carries out all of these tasks. The multi-talent in the compact class of actuating drives distinguishes itself here through its broad portfolio of features and a large number of technical benefits.

The AG05 can be flexibly integrated into various machine concepts, which is particularly interesting for OEMs and opera-tors alike. The star t-up is done either at the drive itself or via

the bus communication. No ad-ditional material is required for assembly. Siko DriveLine product manager Michael Schwab: “The programming effort and the set-up and setting times are minimal, facilitating rapid activation. The user is perfectly supported in an easy star t-up by a two-line display. It also facilitates the monitoring of target and actual values during operation.”

The AG05 has a stainless steel hollow shaft with a diameter of 14 millimetres. The robust glass fibre-reinforced plastic housing has a smooth surface which is resistant to acid and leaches as far as possible. The actuating drive is installed directly on the feed and auxiliary axles. In the compact housing, there is a brushless 24V DC motor with planetary gears, controller, power electronics and integrated field bus interface. The innovative drive is characterised by excel-lent running smoothness with an impressive power density of 30 W/dm³.

The integration into various safety concepts can be done very easily with the AG05 as the power supply for the control and power electronics is done separately. The workload of the

higher-level PLC is substan-tially alleviated by the integrated regulating electronics. Monitoring functions for temperature, power and contouring errors are also already integrated in the drive. The charging status of the bat-tery is continuously monitored so that any necessary change of battery, which can be carried out by the user, is indicated or reported early on. Through the battery buffering of the magnetic measurement system, position deviations are also recorded in a powerless state and repeat referencing is no longer needed.

“The customer benefits from the numerous advantages of the AG05. The actuating drive can be flexibly integrated into the new or existing machine concept and the short cycle and set-up times quickly ensure a very high level of productivity. The excellent price-performance ratio is another plus point,” says product manager Michael Schwab about the new development. “Despite all the technical features, the DriveLine AG05 actuating drive is no larger than a 0.33-litre drinks can.” • Go to www.electricaltechnology.co.nz/enquiry quote: E111120

Designed to meet global standards, Centerline low-voltage MCCs offer a rugged, high-performance packaging solution to meet manufacturers’ needs. With embedded IntelliCenter technology, the Centerline MCCs use a preconfigured and pre-tested network with integrated hardware and software. This level of integra-tion helps reduce installation time with its plug-and-play setup and can help minimise facility downtime by providing intelligent diagnostic and predictive failure information.



Grand opening of Australian Nord subsidiary

The inauguration of Nord’s new Australian subsidiary, Nord Drivesystems Pty. Ltd., took place on 6 October 2011 in the presence of Nord founder G A Küchenmeister, Mark Alexander, Managing Director of Nord Drivesystems Australia, and Gernot Zarp, Head of International Sales at Nord. Nord Drivesystems Australia commenced opera-tions in 2010 with the construction of an assembly hall in the Melbourne suburb of Derrimut and star ted manufacturing

gearboxes and electric motors. Investments into an extension of the paint facility and a modern drying room followed at the beginning of 2011.

The plant has state-of-the-art facilities for geared motor manufacturing. The production and quality assurance processes comply with the standards of the German parent com-pany. The Melbourne site also functions as a service center. Nord Drivesystems Australia maintains sales branches in two further port

cities, Sydney and Brisbane. Regional sales managers serve all the States and Territories in Australia and New Zealand. Nord Drive-systems Pty. Ltd. is a wholly-owned subsidiary of the north German Nord Drivesystems, one of the leading suppliers of full-scale, comprehensive drive solutions. Nord has 35 subsidiaries worldwide and a vast network of distributors who ensure fast availability and global service.

The company was founded in 1965 as a gear manufacturing company by G. A. Küchenmeister and G. Schlicht. Power elec-tronics and electric motors later expanded the product range, so that today Nord is one of the few manufacturers that covers the complete spectrum of drive engineering. A unique selling point is that Nord is extremely flexible in offering and developing very fast customer-oriented services and solutions. Nord has been represented on the Austra-lian continent since the mid-1990s. With the establishment of its own production facilities and the expansion of its sales and services, Nord fulfills the growing demand for intel-ligent and high-performance drive technol-ogy. Nord supplies motors conforming to the relevant Australian energy efficiency specification MEPS High Efficiency and frequency inverters with C-Tick certification.

Decentralised servo drive with multi-EthernetWith its decentralised IndraDrive Mi servo

drive, Rexroth paves the way for speedy engineering, the simple realisation of modular machine concepts, and effective safety concepts. Using a multi-Ethernet interface, the IndraDrive Mi simplifies the realisation of the most varied automation structures with one single type of hardware. In addition, it also allows for Ethernet components to be con-nected directly to the drives, thereby further reducing the amount wiring needed. The certi-fied safety function STO (Safe Torque Off), which is integrated into the drive, increases the degree of freedom for modularisation in machine engineering.

The Multi-Ethernet interface of the IndraDrive Mi reduces the configuration of the communication protocols Sercos III, Profinet IO (RT), EtherNet/IP and EtherCAT to a mere adjusting of software settings. As a result, OEM are able to implement the differ-ent automation structures requested by end

users with one single type of hardware. This makes logistics and spare parts management significantly easier.

The decentralised servo drives reduce the amount of wiring needed by up to 85 percent compared to conventional solu-tions. By enabling additional Ethernet actua-tors and peripheral devices to be connected directly to the drive, these components no longer need to be wired all the way into the control cabinet, which brings installation costs down. Users can now connect Rexroth’s pneumatic and hydraulic actuators to the IndraDrive Mi via Sercos III and access these actuators via the control system.

The integrated “Safety On Board” function Safe Torque Off (STO) eliminates hardware and reduces the need for wiring. Axes equipped with STO ensure operational safety without requiring an additional control system. When the STO function is activated, the drive will interrupt the current to the

connected motor within mere milliseconds. This safely prevents a stopped engine from being restarted accidentally by the drive. The STO function in the IndraDrive Mi is certified Cat 4 PL e according to EN ISO 13849-1 and SIL 3 according to EN 62061.

The question of how New Zealand can be more productive remains a hot topic and for good reason. Antony Gollan explains the important role industry training organisations are playing in tackling our productivity challenges.

In the 1970s, New Zealand’s GDP per capita was significantly ahead of Australia’s, but today our fortunes have been reversed. Our workforce is now only 83 percent as productive as our cousins across the ditch. So how bad is it? And what can be done to remedy this prosperity-threatening situation? The first step is to get a clear picture of the issue, as there are a number of myths that circulate. The first is that we can work harder. New Zealanders already work some of the longest hours in the OECD, yet score among the lowest in productivity per hour worked. This means any gains in productiv-ity will have to come from doing more with the time we are already working – not from putting in more hours.

The second myth is that the mix of Australia’s industries is different to New Zealand’s. This is not true, according to recent analysis by the New Zealand Institute of Economic Research (NZIER), which states that for the most part our countries are doing the same things, “but Australia is doing them better”. The report highlights that labour in some

New Zealand industries is actually more productive than Australia’s, notably agriculture, infrastructure and mining. Also our manufacturing sector is only slightly less produc-tive than its Aussie counterpart. The NZIER concludes that where New Zealand is really falling behind is in our service sector, which employs 70 percent of our workforce and is responsible for 65 percent of our growth. In fact, 70 percent of the trans-Tasman productivity gap can be accounted for by poor performance in this sector. Capital investment was not found to be a factor nearly as much as a lack of worker skills, management capabil-ity, and high-quality organisations.

Another factor contributing to this lack of skills is low levels of literacy and numeracy. A 2006 OECD study found that 42 percent of New Zealand’s workforce lacked the literacy and numeracy skills to perform adequately in their everyday work. This equates to around 1.1 million people, making it a major issue for our workforce. This is about more than reading and writing – literacy skills in this sense include listening and speaking to communicate, and critical think-ing. People with low literacy levels develop coping strategies, which are often complex work-arounds to spare themselves the embarrass-ment of being called out publicly. Unfortunately the sum of these coping strategies has a big effect on productivity, which limits the ability of firms to innovate and implement change. This is becoming more of

an issue as IT and computers take a more central role in everyday work, and workers are suddenly expected to carry out high-literacy tasks they are not equipped for.

Industry training in New ZealandWhile looking closely at productiv-ity can be troubling, the fact that it is skills and not some other factor such as infrastructure or capital investment that is holding us back is cause for optimism. New Zealand already has an impressive national qualifications system, as well as in-dustry training organisations (ITOs) that are well-placed to offer some of the solutions needed. ITOs were created by legislation in 1992. They have three broad statutory obliga-tions to carry out on behalf of their industries: to develop skill standards and qualifications, manage national training systems, and provide skills leadership to their industries. There

are 33 ITOs in New Zealand covering fields as diverse as retail and seafood to construction and sports turf maintenance. Around 105,000 Kiwis are currently gaining qualifications through one of these ITOs.

ITOs essentially represent the training infrastructure for their industries. They have a broad and unique perspective that comes from being the bridge and “honest broker” between firms, the wider industry, government and training providers. To increase productivity, ITOs are tasked with achieving better skilled workers, better management of firms, and better performing industries.

Better-skilled workersBy its very nature, the industry training model is highly responsive and able to identify the specific capabilities a worker needs to perform well in their job. This is

SINGER

Genesis Energy Training and long-time electrical and me-chanical services contractor the Singer Group are to combine in 2012 to train selected trainees in a joint venture which is being hailed as the ‘way to go’ for industry generally. Genesis Energy has been developing this breakthrough model over a number of years now to get the balance right between its own needs and those of the New Zealand electrical industry which, like so many in other developed parts of the world, is facing a severe ‘loss of skills’ scenario as the first tranche of the ‘baby-boomers’ who trained in the Sixties star t retiring.

Dean Smith, Training Manager, Genesis Energy, whose team has paved the way for the initiative, said that 2012 will see the company funding seven trainees and Singer five. Genesis Energy is hoping to line up a number of other partnership deals on a

‘Apprenticeships R Us’ say Genesis Energy and Singer in dynamic apprentice training partnership

similar basis with other suppliers. Wintec, which the company has some history with, has secured the tender to provide the preferred polytechnic role which will see it meet all academic and theory elements of NZQA industry qualifications in support of mechanical and electrical apprenticeships.

“In essence,” says Smith, “Genesis Energy and Singer are combining to promote and encourage youth back into the electrical industry as qualified workers in order to mitigate with smart, new young blood the large number of current workers who will retire over the next several years. This is what Genesis has been working to address for some time now and to progress this we have looked to companies we are affiliated to or associated with to partner us in this new model.

“What we think makes this attractive, to a company like

Singer is that the programme is focussed on delivering the ‘generic tradesman’, not simply skills needed in the electricity supply industry.”

Singer Group boss, Jeff Mclar-en, welcomed the initiative which he believes is not only more equitable on the cost-sharing front, but also has the potential to change the way large industry with its highly-skilled and well-resourced corporate structure can cooperate with a trusted, long-term partner to jointly achieve a balanced output of their own and contribute to national requirements, by combining strengths. “We par-ticularly like the innovation and thinking behind the programme and especially like the name, ‘Apprenticeships R Us’, since it epitomises and simply reinforces the stated purpose and out-come, in one. The fact that Dean and his team achieved a full pass-rate in their last year of the

recent trial-run leading up to this programme, signals very clearly that this is going to be an absolute winner, and one we will be very proud to be partnering in.”

Mclaren noted that the fact that the initial part of the training was on both electrical and mechanical skills matched up perfectly with the profile of services which Singer provides to Genesis Energy at Huntly Power Station and the hydro stations in the Central Plateau to meet their particular needs.

“The local electrical industry, in our experience, is becoming more and more demanding as technology plays an ever-increasing role. But if you don’t have the best of ‘the basics’ you aren’t going to be sound enough on the fundamentals to inno-vate – and deliver the ‘Powerful Solutions’ a growing number of our customers expect of us each working day now.

“But, for those trainees with the drive and ambition to go all the way, these are truly stimulat-ing times, and ‘Apprenticeships R Us’ is going to provide a brilliant learning platform for those who make it onto the course,” Mclaren says.

Smith is rightfully proud of the success achieved in the five-year trial with ‘a community of host companies throughout the North Island’. “We achieved a 92.9 percent completion rate, which compares very favourably with the industry’s national completion rate of some 34m percent. Overall we had 57 apprentices/trainees on the programme, with 10 finding positions in the company and 43 – or some 80+ percent – entering the national workforce with recognised qualifications.

“The big change to the

new national apprenticeship programme is a move from a fully-funded model to a user-pays model, with any interested community or host company, like Singer, joining the programme under a service contract with Genesis Energy. We are able to keep the cost to the partner companies low by accessing Modern Apprenticeship co-ordination funding, along with industry funding though the appropriate ITO.”

Current projections see Genesis Energy taking on four to eight apprentices each year to meet their workforce needs and growth requirements, with approximately three to four host companies in addition to Singer expressing interest in joining the new user pays apprenticeship model.

According to Smith, partner companies would be entering into a service contract with Genesis Energy to provide the following services over a three-year apprenticeship:

• Support in the selection of apprentices (if required).

• Recognition of prior learning and competency, prior to the establishment of training agreements.

• Establishment of training agreements and pathways.

• All administration and co-ordination associated with the following parties:• Associated Industry Training a Organisations (ITO’s).• NZQA• Polytechnic• External training providers, if

required. • Partner organisations.

• All on-job assessment in support of agreed training pathways.

• Quarterly reviews and training reporting• All moderation associated with the

apprenticeship programme.• All apprentices will be employees of

the partner company, which will meet all associated mechanical and electrical pathways.

“In return, the partner companies pay a fair share of the costs and they are able to access the apprentices when they need them. A big plus for Genesis Energy is that by working with the partner companies, the apprentices get a broader experience than they would with us, but by the same token those who would only have had partner company experience will also get heavy electrical industry exposure.

“This alone is bound to improve the flexibility, adaptability and development of the new trainees,” says Smith.

The programme organisation is already in full swing. Recruitment advertisements have already been placed in the appropriate

media. Interviews and selection, as well as notification and offers of employment were scheduled for completion in the earlier part of November. The final schedule of the Training Programme will be confirmed between Wintec, Genesis Energy and partner companies before year-end.

Apprentices are scheduled to star t in early February.

Ian Brothers, who recently rejoined Singer as business development manager, Generation Services, and who has long been associated with Genesis Energy’s Huntly Power Station, also welcomed ‘Apprenticeships R Us’.

“As Dean puts it so well; together Genesis Energy and Singer can ensure that trainees get the core competencies they need; giving them both competence and confidence in general trade positions. Singer doesn’t do all the things that a trainee needs to do to get qualified, and vice versa.

“We can give them broader experience simply through our breadth of operations, but Genesis Energy has the skills, experi-ence and staffing in the training profession which we could never hope to have in place.

“That’s why this is such a good model, and I have been more than comfortable championing it to my colleagues and Jeff,” says Brothers, whose own career across the breadth of the electrical industry would set a great benchmark for trainees.

The final word is with Smith who is confident that ‘Apprenticeships R Us’ will deliver a win-win for everyone involved.

“We’ve emphasised the business model and the benefits for the partners, but I’d like to wrap up with what this programme is going to mean for the next generation of trainees: Firstly, they will get a sound gener-alist mechanical and electrical engineering foundation, which turns them into good core tradesmen, with all the skills to make a good living.

“That’s important. But secondly, from there they will have a better understand-ing of their own skills and interests and will have the insight to understand what employers across the industry are looking for, so they can advance and align their skills and specialise in accord with industry needs.

“We anticipate this programme will run for a number of years, and be tweaked and refined based on experience. So those who have missed out on the first intake can get updates on the first course, as it progresses, from our website, and will have early notice of the intake process for 2013,” he says.

because the model is premised on input from industry – qualifications are developed in consultation with subject matter experts and industry associations who cooperate to ensure they are getting what they want from the final qualifications. ETITO is currently in the process

of doing exactly this, with its latest “sector review”. This is a hard look at qualifications across the entire industry, and the qualification review that will follow will take into account the convergence of electrotechnology and telecom-munications skills, while also ensur-

ing that the latest educational practices are taken into account.

Literacy and numeracy in their industries is also a big issue for ITOs. While the method they apply varies depending on the nature of the industry and its ITO, ETITO is using an “embedded literacy” approach for the electrotechnology and telecommunications industries. What this means is that in the long term, ETITO aims to create an environment where apprentices can raise their skills in these areas as they engage in their regular training – by using contextual examples that relate to their work. An example of this would be a tutor developing the communication skills of their ap-prentices by asking them to briefly sum up the content of what they have covered at the end of each lesson. Apprentices are assessed using an online tool at the beginning and the end of their training – so skill levels can be tracked both individually, and across the industry. The results are shared with training providers, so the tutors can use it to inform their lesson planning.

Better management of firmsWhile the main job of ITOs has always been to develop the vocational qualifications for people working in the industry, increasingly their skills leadership function has prompted a look at other ways to improve the performance of firms. Due to the fact that many business owners with trade backgrounds didn’t get where they are today via business school, their toolbox may benefit from a few additional strate-gies. Industry training organisations, including ETITO, are increasingly interested in partnering with firms to move beyond delivering core qualifications and actually working on the business itself.

For ETITO, this has meant the development of business adminis-tration qualifications for office staff in contracting firms, along with the National Certificate in First Line Management [Level 4], which is intended for qualified tradespeople who have moved into a manage-rial role. ETITO is also including business management components into higher level qualifications in response to feedback from industry.

This will continue to be an area of growth as firms come to engage with their industry training organisations as skills partners, and ITOs are able to fulfil that role. ETITO has in the pipeline a Lean Business Thinking qualification that is based on principles of Kaizen, which is about an ongoing commitment to identifying small areas where productivity gains can be made in the business, and then reaping the cumulative benefits.

Better performing industriesITOs also have a role to play in working on behalf of their industries. Their pan-industry focus can foster cooperation between firms when there are clear gains to be made, and they can use their relationship and links to government to advocate on behalf of their industries. The best example of this advocacy in action is the work of the Built Environment Training Alli-ance (BETA) in which ETITO plays a leading role. Among other things, BETA is leading the response from a skills perspective to the challenges of the Canterbury earthquakes and reconstruction.

The challenges that come from rebuilding New Zealand’s second largest city are simply too big and too complex for firms to handle on their own. ITOs have been able to draw together their industry groups and represent their views to government. This has included embedding “skill liaisons” within the project management organisations responsible for awarding projects in the city, to ensure that they are well- versed on matters relating to skills.

The solution lies in working togetherAs the industry training sector continues to mature and discover the value that it can deliver to New Zealand industries, you can expect to see ITOs adapting in the medium term. However we meet New Zealand’s productivity challenges, you can bet that ITOs will play an important role – and this will be done by acting in concert with the industries they represent.

During recent weeks considerable progress has been made with the publishing of the AS/NZS 3000 Amendment A which occurred on the 30 September 2011.

In mid-October 2011 the Government approved the issue of the Electricity (Safety) Amendment Regulations 2011.

The release of these two documents now enables the amendment No. 1 of the Electricity (Safety) Regulations 2010 to proceed, and as Schedule 2 covering the publication dates of the referenced standards has been brought up to date, this will allow also allow AS/NZS 3000 Amendment A to come into force. The date that this milestone will be reached is to be 10 November 2011.

What has changed?AS/NZS 3000 Amendment ANote: There will be a six months phase-in of the new requirements of Amendment A.

The first major change is to clause 2.6.3.2.2 and is being replaced by a re-drafted clause. This will remove the requirement to protect all socket outlets in a school class rooms where school children up to school year 8 (last year of immediate school level) with an 10 mA RCD. This change was made after reconsideration of the safety outcomes delivered by the former requirements.

The only requirement will be to protect socket outlets used for craft work with a 10 mA RCD. All other socket outlets will have no RCD provision but will be required to be marked with intended purpose, for example “IT equipment only, NO RCD protection”.

The existing exceptions 1 to 4 to clause 2.6.3.2.2 are now covered by other provisions within the Wiring Rules and Electricity (Safety) Regulations 2010 + amendment No. 1.

An additional NZ-only paragraph is added to clause 3.4.1, this extends the current position so that if the area where fixed wiring is run is required by the NZ Building Code to have thermal insula-tion fitted, all cabling must be provided on the basis that thermal insulation will be installed after the fixed wiring has been enlivened. All electrical

designs will take to take-in the fact that installation of thermal installation could occur and de-rated all fixed wiring and carefully consider the rating of overcurrent protective devices.

This requirement will result in the many “rules of thumb” used for domestic installations for many years will be needed to be checked and, if required, update these “rules of thumb” to cater for the new circumstances.

A new NZ-only clause 4.1.5 is added for electrical fittings and equipment that could be covered by the later installation of thermal insulation to NZ Building Code requirements. All electrical designs will have to take in the fact that installation of thermal installation could occur and all electrical fittings and equipment must be suitable to be covered or be clearly marked so that when thermal insulation installed the insula-tion installers will be advised that covering of the fitting is not permitted, NZS 4246 refers. This is of particular importance for downlight luminaires.

A new NZ-only provision is to be added to clause 4.5.2.3 to cater for new developed types of downlight luminaires that are tested to AS/NZS 60598.2.2, this standard has a NZ-only amendment to cover NZ-specific conditions.

Table 4.7 dimension C is being amended for NZ use, following testing work done by BRANZ. Figure 4.7 is only used if the downlight luminaire manufacturer’s instructions have been lost or are unavailable. The first option when installing downlight luminaires is to use the manufacturer’s instructions. The second option is to use the default instructions in AS/NZS 3000 clause 4.5.2.3 and figure 4.7.

The AS/NZS 3000 amendment A changes will come into force when the current Electric-ity (Safety) Regulations 2010 schedule 2 is updated in early November 2011. Amendment A will be incorporated into AS/NZS 3000 amendment 2 when issued next year and Amendment A will be revoked.

A greater number of changes will occur in Electricity (Safety) Regulations 2010 amendment No. 1.

The Electricity (Safety) Regulations 2010 amendment No. 1 was first approved as the Electricity (Safety) amendment Regulations 2011 but the amendments will be imbedded into the original Electricity (Safety) Regulations 2010 and

renamed as Electricity (Safety) Regulations 2010 + amendment No 1. It is expected that amended regulations will be available shortly before the in-force date of mid-November 2011. A copy of the amended regulations for downloading is expected to be available from the Energy Safe website.

Schedule 1 – Minor corrections to intent.

Schedules 2 and 4 – Amended to cover updated issues of applicable standards.

General commentsTaking all the above comments the major changes are as follows:

1. Downlight luminaires, the NZ position is that there are additional ap-proved luminaires available for use. The additional fittings have been approved in NZ for NZ conditions.

2. The effect of reduced cooling by additional thermal installation on the fixed wiring and fittings in domestic installations will now require to be fully considered when installing and enlivening the fixed wiring and fittings. This is due to the new provision that the reduced cooling effects caused by thermal insulation must be catered

for at the initial installation, as the NZ Building Code will require the installa-tion of thermal insulation as part of the final building certification process.

3. The use of 10 mA RCD in school classrooms has been reconsidered and the requirements have been reduced.

4. The definition for “Mains work” has been revised to clarify the inspec-tion required by electrical inspectors.

5. The requirements for a DoC (Me-tering) have been reviewed and higher requirements are now necessary.

A period of adjustment will be required by all electrical workers. Changes by the revision of AS/NZS 3000 + amendment No. 2 will occur mid-2012. Many of the major changes being proposed are already covered by the amendment of Electricity (Safety) Regulations 2010 and the amendment A of AS/NZS 3000. New additional items include clearances between electrical installations and gas installations. A general review to clarify intent will also be made.

The review of certification announced earlier this year by the government, is not scheduled to start until late 2012 – early 2013.

Alan Cuthbert, National Secretary

NZEI member and Manukau Institute of Technol-ogy lecturer John Lamb has recently returned from a year’s secondment helping to set up the electrical engineer-ing programme at Bahrain Polytechnic. John gave the Auckland Branch a presenta-tion of his experiences and the efforts being made in Bahrain.

John Lamb’s NZEI presentation at Manukau Institute of Technology (MIT) commenced with some new and not-so-new members

Students at Bahrain Polytechnic used a power drill as prime-mover.

most diligent student.John then gave a fascinating

presentation on “Problem-Based Learning” methods that are being implemented at Bahrain Poly-technic for the BEng Tech Degree – Electrical Engineering, Electrical Power and Machines course. In semester two 2010-2011, John was the teacher for Electrical/Power Machines and assisted with PLCs.

The polytechnic students really

enjoyed the hands-on problem solving methods used to build a three-phase synchronous machine (motor/alternator). They saw it as a great way to cement in place the understanding of fundamentals, such as grabbing the nearest power drill when in need of a prime-mover. This system of working in groups fits the Bahrain psyche as the people there are very socially- oriented by nature. The gender ratio in electrical engineering is about 60/40 male/female.

The female student project was to make a three-phase induction motor from scratch using basic materials, but there were also superb resources available such as Allen Bradley gear and a machines laboratory. Other projects/labs included power factor correction, metering (VAr, Watts, Amps, Volts and PF) and experiments with fluorescent light fitting ballasts and capacitors.

Students at Bahrain Polytechnic are required to complete 80 days of approved work placements. It is expected that this will normally occur in four-week modules in each of the four years of the programme.

Establishing the polytechnic was

driven from the growth and diver-sification of Bahrain’s economy that is creating a demand for a more highly skilled Bahraini workforce and graduates who are work-ready and equipped with the necessary knowledge and skills to make an immediate contribution. The aims are to bridge the labour market demand for skilled technical and applied professional graduates and to replace the increasing expatriate work force in the private sector with skilled Bahrainis.

The attendees learned a lot about the history, industry and social structure of Bahrain during

John’s presentation, far more than can be relayed here. One topic of special interest was John’s introducing the Trade Centre towers that are inter-connected by three wind turbines. It is currently the only such building in the world generating all its own power, and beautifully designed too. It would be great to see such designs con-sidered in New Zealand – maybe with the rebuilding of Christchurch as a true Eco-Centre?

Yokogawa releases multi-input temperature transmitter

Reliable transmission in moving vehicles

Yokogawa Electric Corporation has released its YTMX580 multi-input temperature transmitter. The YTMX580 is based on the ISA100.11a industrial automation wireless communication standard and has eight analog input channels. Yokogawa Managing Director Australia & New Zealand, John Hewitt, said Yokogawa patented the world’s first digital sensors for flow and pressure measurement and moves were afoot to make the ISA 100.11a protocol an international standard to organically integrate wireless technology with existing wired communications networks. A temperature transmitter such as the YTMX580 accepts input from a temperature sensor such as a thermocouple or a resistance temperature detector (RTD) and converts this to an electric signal for transmission to a monitoring and control system. “One application of temperature transmitters is temperature profiling, which involves the use of several internally-mounted temperature sensors to precisely grasp the temperature

Advantech has announced the EN50155 cer tification of its unmanaged Ethernet switches; EKI-6528TI and EKI-6528TPI PoE switch. The switches are designed to transmit data for many applications such as video surveillance systems and carriage status monitors, on high speed rail lines, subways, trams, or buses. The wide temperature range switches have passed EN50155 cer tifica-tion which enables them to withstand severe shock and vibration, therefore ensuring reliable transmission in moving vehicles. The Ethernet switches also offer an auto bypass feature to guarantee train communication is not interrupted in the event of power failure in a carriage. • Go to www.electricaltechnology.co.nz/enquiry quote: E111130a

distribution inside a plant’s reactor, tank, or boiler,” says John Hewitt. In the process auto-mation field, a single temperature transmitter is usually installed for each measurement point. “Hence, with a high-density temperature measurement application such as temperature profiling, a large number of single-channel temperature transmitters is required. By using a temperature transmitter that supports multiple input channels, our customers will not have to use as many transmitters, thereby reducing their initial installation costs and improving maintenance efficiency.”

Conventional transmitters typically output a 4 – 20 mA electric signal, explains John Hewitt. “The latest transmitters rely on digital communications, which enables a single trans-mitter to output a great quantity of informa-tion, including data on device status. This is the essence of Yokogawa’s field digital technology.” The use of secure wireless technology allows customers to easily increase the number of measurement points without having to worry about time-consuming and difficult wiring. “The use of wireless communications also means that transmitters can easily be installed in locations that are physically difficult to wire or that previously were economically unfea-sible. These are the benefits of a Yokogawa field wireless solution,” says John Hewitt.

Based on the field wireless concept, Yokogawa is releasing the YTMX580 to bring users the benefits of secure wireless instru-mentation, which include the reduction of the overall cost of implementing a high-density temperature measurement application. Eight

temperature sensors can be connected to each YTMX580. This product is capable of accepting thermocouple, RTD, millivolt, resistance, and 4 – 20 mA input (requires shunt resistors). The type of input can be independently configured for each channel. When three channels or less are in use, signals can be output to a monitoring and control system at intervals as short as one second; with four or more channels, signal output intervals can be as little as two seconds.

The YTMX580 is powered by internal bat-teries that provide years of use under normal operating conditions. This, combined with the support of the ISA100.11a wireless com-munications standard, makes this transmitter very easy to install. An added benefit is that the YTMX580 has the same battery pack used in Yokogawa’s ISA100.11a compliant EJX-B series pressure/differential pressure transmit-ters and the YTA510 temperature transmitter. Customers already using these wireless products will therefore only need to keep one type of battery pack in their inventory.

“Our major target markets are oil, natural gas, petrochemical, chemical, iron and steel, pulp and paper, electric power, water treat-ment, and other process industries,” says John Hewitt, “with possible applications ranging from high-density temperature measurement in process plant tanks, drying furnaces, boilers, motors to oil, natural gas, and chemical plant cracking furnaces, distillation columns and reactors.” • Go to www.electricaltechnology.co.nz/enquiry quote: E111130



High-density miniature circular connectors

As the demand for portable and miniaturised electronic devices with more functionality growths, so does the need for miniature high-density connectors. The new MiniMax Series from Fischer Connectors is particularly suited for ruggedised devices designed

for handheld or body-worn applications for patient or soldier, instrumentation and test equip-ment where user-friendliness and easiness to handle are a must. The miniature circular connectors offer high pin-density and mixed connections and allow the user

Power monitoring terminal for highly precise measurementThe new EL3773 power monitoring terminal for the Beckhoff EtherCAT I/O system is designed to monitor the condition of a three-phase AC or a DC mains network. It collects instantaneous values of power and voltage at an extremely fast sampling rate of up to 10,000 samples/s and makes them available to the higher-level PC controller for calculation or analysis. The input channels are transferred via oversampling; this results in the acquisition of actual values with a significantly higher resolution in terms of time than the communication cycle time. The EtherCAT distributed clocks method is used as the basis for the highly precise acquisition of measured values in the EtherCAT

to pack more functionality into smaller devices. They feature a unique combination of twenty signal contacts (0.5A) and four power contacts (5A) in one single connector, providing three times more pins compared with a standard Fischer connector with similar size. The ultra-miniature size will save more than 40 percent space compared with a standard Fischer connector with similar pin count and thereby solves many miniaturisation challenges. Thanks to its miniature design and innovative technol-ogy, so the manufacturer says, the connector also saves more than 75 percent in weight and improves the portability of the user’s devices.

Ergonomic rugged design and compactness make it convenient to manipulate with one hand only, even with gloves. It is equipped with endurable keying as well as visual colour coding to avoid misconnection and improve end-

terminal system. These distributed clocks synchronise the EtherCAT devices with very high precision, independently of the PLC cycle.

The EL3773 EtherCAT terminal measures voltage and current via three channels in each case. The six channels are measured simultaneously based on the EtherCAT oversampling principle with a temporal resolution of up to 100μs and passed on to the controller. The maximum sampling frequency for each channel is 1kHz. On the basis of the data supplied, it is possible with the aid of a PC to calculate true RMS values, power, power factors and frequency, and complex user-specific algorithms via the voltage and current curves. The fast sampling rate

also enables the measurement of voltage and current peaks. Using the EL3773 power monitoring terminal, interference can be detected and corrected promptly in order to avoid damage to

devices, increased electric-ity costs and downtime and to optimally boost the productivity of manufacturing facilities.


user safety. It also incorporates a reliable and user-friendly push-pull locking or quick-release system. The Fischer MiniMaxTM Series is IP68 rated, even unmated, which makes it suitable for underwater applications even in case of accidental disconnection. It is also waterproof down to 120m for a full 24-hour submersion. For a fast and easy integration, plugs are pre-cabled and overmolded and receptacles are pre-wired. Soft-sealing caps are also available to protect the connectors in the field. “These connectors are solving design challenges where contact density and space are premium commodities,” says Dominique Glauser, CEO Fischer Connectors SA. “The Fischer MiniMaxTM Series is a perfect marriage of high-density and mixed pins, miniature and ultra-light design and performance.”

Photoelectric sensor for strict hygiene zonesIntended for industrial zones where hygiene is given top priority, the new photoelectric sensor from Schneider Electric is designed to withstand the harsh everyday routine of thorough cleaning. OsiSense XUK-S is encased in a resilient 316L stainless-steel housing, with IP69K protection rating and Ecolab certification. The housing surface is very smooth, cre-ating no gaps or overlaps, therefore

it can easily resist foam baths of aggressive detergents, high-pressure rinses with waters, and temperature peaks of up to 100°C. The sensor can also come in contact with the end product, without the risk of its parts becoming loose or damaged. The smooth steel case of OsiSense XUK-S is equipped with a special feature, a metal flat flush button. Unlike customary push buttons, it is

hermetically sealed into the device housing. This compactness of the sensor makes it suited to the instal-lations in strict hygiene zones, such as those in the food and beverage industry, pharmaceuticals, biomedical technology, and primary packaging.

OKW Walltec wall-mounted casesOKW Gehäusesysteme, repre-sented in New Zealand by So-anar, has released the innovative range of Walltec wall- mounted cases. These sturdy cases are created for use in measuring and control technology, heating, air conditioning and ventilation technology as well as for machine and industrial controllers, etc. This range of wall mounted cases is available in six different case sizes and in two versions, with and without case cover. The cases have two separate areas. The upper area is for the vertical or horizontal installation of printed circuit boards and mounting plates with the help of the integrated attachment domes/ridges. The lower compartment is intended as a separate terminal compartment – accessible at all times for terminal or subsequent maintenance work. To protect the display and operating ele-ments, the Walltec series can be


ordered with a transparent case cover. The standard material for this version is polycarbonate (UL 94 5V). This material has high UV resistance, which means that the cases can also be used outdoors. The transparent cover can be opened and closed easily with the user-friendly locking system (turquoise green, RAL 6016), which can be mounted on the left or on the right using hinges and snap locks. To prevent the case being opened by unauthor-ised persons, it is also possible to lead-seal the case cover as well as the terminal compartment cover.

The second version of the case without cover is made of impact-resistant ABS (UL 94 HB). To complete the case, it is possible to choose either an aluminium-front panel or a front cover in the standard colour of light grey (RAL 7035). The Walltec series can be mounted directly on the

wall or by means of optionally available wall-mounting brackets. The range of accessories also includes suitable DIN mounting rail brackets and the appropri-ate mounting plates. The basic

case with case cover or front cover meets the requirements of protection class IP65.

The data radio can be used to connect a wide variety of field devices directly, including PLCs, control-lers, HMIs, DCSs and transmit-ters as well as level, pressure and temperature sensors. It allows extension of the widely-used Modbus communication proto-col to many applications where wiring is impractical because of distance or accessibility.

The large wireless networks enabled by the new radio provide previously unavailable information to users in a wide range of indus-tries. In irrigation, soil moisture can

be measured, zone valves can be operated and flow rate measured. In automated parking applications, literally thousands of parking spots citywide can be monitored. More traditional applications include tank level, pressure, flow and temperature monitoring in a variety of markets.

Using the data radio clusters can be combined and connected to create systems with 2,400 wire-less points. For even larger sys-tems, multiple wireless networks can co-exist in the same physical area without interference. The radios are configured for rapid, easy connection to all remote and central control elements in a network. They are powered by 10 – 30 VDC. Special low-power sensors can be operated with battery or solar power supply.

Klein test meters and VDV range

Smallest infrared LED in its class

Klein Tools has been manufacturing profes-sional hand tools for over 150 years. The company is dedicated to supporting electri-cians and professional tradespeople with quality and reliability they can count on. The Test & Measurement product line has been exclusively designed from the ground up – by electricians for electricians – working side by side with Klein’s team of engineers and product experts. Based on years of field research, combined with extensive input from electricians, these meters and testers were specifically loaded with the latest innovative features designed to meet and exceed their specific job requirements. Within each prod-uct classification, says the manufacturer, the meters and testers boast more features than comparable products in the category. That translates into more efficiency on the job, additional benefits to the user, and superior

value overall. Some of Klein’s innovative features (which vary by model) include:

• Large backlit displays • High safety ratings • Analogue bar graphs for fast moving values • Low impedance to reduce “ghost” voltage for more reliable readings• Magnetic mounts• Work lights • Hook design for tight spots

Klein has recently released an extensive line of Voice/Data/Video (VDV) testers and tools that meet or exceed the needs of profes-sionals. VDV testers and tools help prepare, connect and test CATV, home theatre, satellite, network, phone and security systems. Hamer Limited is New Zealand’s distributor of Klein Tools products.

The IR Oslon SFH 4715S is, according to its manufacturer, Osram Opto Semiconductors, today’s smallest infrared LED with more than one Watt optical power. The device measures only 3.75 x 3.75 mm² and therefore facilitates very compact illumination units for CMOS and CCD cameras. Osram’s nanostack chip technology and a temperature-stable Oslon Black Series package paved the way for the high performance device. The infrared LED typically provides 1070mW optical power at 1 A operating current, and it features a typical thermal resistance of only 6.5K/W. A lens with +-45° emission angle is integrated in the device. Due to this adapted outcoupling lens the LED delivers 15 percent more output power than components without lens. With a wavelength of 850nm, it is particularly well-matched with the sensitivity of CMOS and CCD camera sensors. The small package allows compact arrangements which enable a very high power density. 3D cameras especially benefit from the improved power since the IR-LED can be modulated up to very high operating currents of 5A in the range of 10MHz.

To achieve the impressive ratio of device

size to power, Osram Opto Semiconductors combines its nanostack chip technology with the temperature-stable Oslon Black Series package. The highly-efficient stack chips have two p-n junctions connected in series and generate nearly twice the optical power of conventional emitters. The Oslon Black Series package is based on a metal lead frame, and its thermal expansion matches exactly the thermal behavior of circuit boards. Thus a high cycle stability is achieved, even at heavily fluctuating temperatures as may, for instance, occur outdoors. In other respects too, the LED complies with the highest quality standards, for example with the automotive standard AEC-Q101. The manufacturer ensures an operating lifetime of up to 50,000 hours. The IR Oslon is fully compatible with its counterpart for the visible spectral range. Manufacturers of street lighting or CCTV systems who combine visible and infrared LEDs can use their experience with Oslon Black Series LEDs and apply existing designs and board layouts.

With the IR Oslon, Osram Opto Semiconduc-tors expands its position in the field of infrared illumination and complements its range of

products with an additional power class. The new device particularly addresses the security industry. Possible applications range from spotlights for IR cameras and CCTV systems via machine vision solutions to number plate recognition. For Dr Joerg Heerlein, Marketing Manager for infrared devices with Osram Opto Semiconductors, the IR Oslon hallmarks the beginning of a new product family: “As our next move we plan a 940nm version. The longer wavelength reduces the so-called red glow effect: since humans perceive intensive infrared light as a faint red glow, this IR Oslon is especially tailored for light sources which should not be seen by people.”

Reliable power supply over four decades

POF repeater with integrated diagnostic function

Since 1971, well over a hundred million of Hirschmann’s ST-series connectors have been produced. Still retaining practically the same original design, these connec-tors are used to provide power for electric awnings, blinds and shutters. The maximum rated voltage is AC 400 V/DC 250 V, with a rated current of up to AC 16 A/DC 10 A. Because the connectors are reliable, easy to install and have a long operational life they have become the standard for a wide range of applications including mechanical engineer-

ing, lighting technology and the medical sectors. The ST-series includes cable plugs and panel-mounted connectors together with their respective sockets. Four connector versions with different numbers of poles are available: (2+PE, 3+PE, 4+PE, 5+PE). The connectors are offered in molded-cable or field-attachable versions. Customer-specific variants can also be supplied on request. The field-attachable versions are suitable for cross-section diameters of up to 1.5mm. They can be attached rapidly and securely using screw or

crimp terminals without the need for any special tools. Strain relief is provided by a PG11 cable gland

and an interior cable clamp.


With its FreeCon Active Repeater, Weidmüller offers a POF repeater with an integrated diagnostic function for deployment in Profinet networks. Today, fibre-optics based on polymer optical fibres (POF)

are increasingly being used, not only because they are immune to electromagnetic interference, but because they are also able to meet the demands of auto-mated applications for greater data volumes. However, these fibres are subject to a natural aging process, which successively increases fibre attenuation. That in turn increases the need for exact diagnostics of the transmission path. Weidmül-ler developed the repeater in response to this need: to guarantee

reliable transmission of the Eth-ernet data being transmitted the FreeCon Active checks the entire transmission path in real time with regard to its optical budget – for example, from the electrical cabinet to the head of the robot. The device sends an alarm signal to a higher-level controller if a defined tolerance level is exceeded and the user needs to replace the cable set. By continuously checking the at-tenuation of fibreoptic transmission paths, FreeCon Active Repeaters

now make it possible to pre-cisely plan when to replace robot cable sets. In conjunction with the HTX-IE POF multifunctional tool, which is designed to ensure rapid and repeatable preparation and termination procedures for SC-RJ type connectors, Weidmüller offers a complete all-round package of components for transmission solutions based on POF cabling.
