There’s no need to be fearfulof bidding on an explosionproof project. The importantkey is to make sure thatyou’ve got the correcthazardous location rating.
Remember that you’ll needthe Class, Division, NEMAand Group that the electricalequipment needs to complywith. Any safety officer onsite should know thisinformation.
It is not enough to requestonly that the equipment mustmeet explosion proofrequirements as there are threeways this can be done.
If non explosion proofequipment is installed inlocations that require thisprotection an explosion canoccur.
Taking on a explosion proofproject can go smoothly or notgo smoothly. Let us help youwith it so it goes as smoothlyas possible.
By taking on an explosionproof project like this you’llbe separating yourself fromthe other guys. It could be away of carving out a niche foryourself as an explosion proofelevator components installer.
Add explosion proof to yourproject portfolio and you’llsee more opportunities forfuture work.
Pictured Above:, A grainprocessing facility explodedwhen too much grain dustbuilt up and ignited. Whenwe think of explosion proof,we typically think about oiland gas, however any smallparticle has the power toexplode with out warning.
The following is an overview ofhazardous location classificationsas they apply to elevatorequipment. This is intended to giveelevator sales, technical and fieldpersonnel a better understanding ofthe hazardous locationdesignations and the equipmentavailable to meet theserequirements. The actual processesemployed to define and assignhazardous location designationsare complex and beyond the scopeof this summary. For completedetail and installation instructionssee Article 500 of the NationalElectrical Code.
GeneralHazardous location elevatorequipment is necessary in any areawhere the possibility of fire orexplosion exists, or may existbecause of flammable gases orvapors, flammable liquids,combustible dust, or ignitablefibers. These types of dangers areofficially classified by location(Class, Division, and Group)depending on the properties of theflammable vapors, liquids orgases, combustible dusts or fibersthat may be present and/or thelikelihood that a flammable orcombustible concentration orquantity is present.
From an elevator contractorperspective it is safe to say that ifthere is any likelihood that a fire orexplosion could conceivablyhappen, hazardous locationequipment should be installed,even if not specified by thecustomer.
Class I AreaClassificationAreas in which flammable gasesor vapors are or may be present inthe air in quantities sufficient toproduce explosive or ignitablemixturesareClass I.
Group A, B, C & D - Defines thetype of combustible gases in theClass I location atmosphere.
Class I Area Groups:Division 1 and 2A(acetylene)B (hydrogen) C (ethylene) D (propane)
Class II AreaClassification Areas where combustible metal,carbonaceous dust, or othercombustible dust such as flour,grain, wood, etc., are or may bepresent in the air in quantitiessufficient to produce explosive orignitable mixtures are Class II.
Group E, F, & G - Defines thetype of combustible dust in theClass II location atmosphere.
Class II Area GroupsDivision 1 & 2 E (metals -— Div. 1 only)F (coal)G (grain)
Class IIIAreaClassificationAreas that are hazardous becauseof the presence of easily ignitablefibers or flyings, but are not likelyto be in suspension in the air inquantities sufficient to produceignitable mixtures are Class III.
Class III GroupsDivision 1 & 2 None.
Division 1 AreaClassificationADivision 1 location is one inwhich the ignitable or combustiblegases, vapors or dust can existunder normal operating conditions.
Division 2 AreaClassificationADivision 2 location is one inwhich the ignitable or combustiblegases, vapors or dust are stored,handled, processed or used, butnormally confined within closedcontainers or systems, or dispersedby positive mechanical ventilation.In this division the hazard iscreated by accidental rupture ofcontainers or systems, orequipment failure.
NEMA ClassificationsHazardous location enclosures arerated based on the Class andGroup to which they will beinstalled. These are:
NEMA 7 - Enclosures for use inlocations classified as Class I,Groups A, B, C, or D.(Combustible gases)
NEMA 9 - Enclosures for use inlocations classified as Class II,Groups E, F, or G. (Combustibledust).
NEMA 4X - Enclosures for usein Class 1, Division 2 locations ifused in conjunction withhermetically sealed contacts.Water/Corrosion ResistantEnclosures are constructed toprovide a degree of protectionagainst falling dirt, rain, sleet,snow, windblown dust, splashingwater and corrosion.
Summary &RecommendationsTo summarize these hazardouslocation classifications for elevatorapplications: (1) the Class andGroup designation specifies if theexposure is gaseous orcombustible dust and (2) theDivision specifies if the hazard isalways present or exists only whena problem occurs.
Because the Class I or II, Division1 category indicates that the hazardexists under normal conditions it isour recommendation that elevatorcomponents used have a NEMA7or 9 rated enclosure. This is themost stringent application.
In Class I or II, Division 2 areasexceptions to the enclosure ratingare allowed. For elevatorapplications in Division 2, generalpurpose enclosures are permissibleif used in conjunction withhermetically sealed contacts. Formaximum protection the generalpurpose enclosure should beNEMA4X rated.

Custom made for passenger or freight elevators,these CJAhazardous location fixtures aredesigned for Division 1 applications, will containan internal explosion, and prevent the ignition ofcombustible dust.
Class 1 & 2, Division 1 are stringent ratings.For these we use NEMA7/9 enclosures, buttonsand key switches. To make this applicationmore attractive or eye appealing we often willattach a stainless steel cover “skin.” This “skin”can be custom engraved and gives the fixturemore of a conventional elevator productappearance. In addition, it can containinformation such as fire service instructions, etc.which cannot be put on the covers of thestandard NEMA7/9 enclosure.
Custom engraving is available, including arrows,words, pictograph, logos and instructions.

Custom made for passenger or freight elevators,these CJAhazardous location fixtures aredesigned for Division 2 applications. InDivision 2 conditions, enclosures for non-hazardous locations may be installed if theequipment does not constitute a source ofignition under normal operating conditions.
For these Class 1 & 2 Division 2 applicationsthere are several different approaches which canbe used to accommodate these requirements.The one most often selected is the CJAstainlesssteel button coupled with hermetically sealedcontacts. These buttons and contacts can beused with NEMA7/9 enclosures as shown here,or with NEMA4X enclosures. The NEMA4Xenclosures are less expensive and can containmany more features than the NEMA7/9enclosures.

Purged CabinetsIf you have a purged line throughout thebuilding you may be able to utilize it anduse a NEMA 4/12 or 4X cabinet insteadof a NEMA7. Purging devices pump acontinuous supply of air into the cabinetand creates more pressure inside thecabinet than outside.
Available for both Class 1, Division 2and Class 1, Division 1 this option is onethat might be preferable to the traditionalNEMA 7 Cabinet option.
VVVF Variable Voltage Variable FrequencyFor traction elevators traveling faster than 100 FPM. Solid Statecontrols, dynamic braking and force guided relays make ourcontrollers the most solid state in the industry. For elevators thatare under 150 feet per minute no encoder feedback from themotor is required. For speeds 150 feet per minute and above werecommend that you use encoder feedback. We can provide anew motor and encoder for your elevator system along with anew controller.
RTC-1 - Soft Start For One Speed MotorsFor traction elevators that travel less than 90 FPM. With thissystem, stopping of the elevator occurs when the elevatorcomes to the floor and the door zone sensor is activated. Thebrake sets and the elevator stops. The slower the elevatorelevator travels the better this controller stops. Motor control isby Power Electronics Smooth Control or soft start from one ofthe other soft start manufacturers.
RTC-2 - Soft Start For Two Speed MotorsFor traction elevators with speeds less than 180 feet per minute.This is a very good alternative for older elevators. Soft startunits are controlled by the Power Electronics 2 Speed SmoothMove. It slowly ramps up into the first motor winding and thenthe second and it also has the ability to slow down when aselector is added to your elevator. We can provide this as a PLCBased system or relay logic without Fire Service for repair orlike for like replacements.
Hydraulic - Soft Start, Wye Delta or SOLOur CJAcontrollers for hydraulic projects are ideal for directreplacement or new installations and have solid state industrytype PLC and components that are readily available and off theshelf in the event of a shut down. Available with Soft Start, WyeDelta or Straight Accross The Line, we can build a controller tomeet your specifications.
VVVF Line RegenLine Regeneration with elevator controllers is being specifiedfor more and more projects. Instead of energy transforming intoheat when the elevator stops and dissipating into a resistor bank,the energy that’s created when the elevator stops gets pushedback into the AC line through a REGEN unit. The upfront costassociated with line regenerative drives is more than atraditional VVVF controller. However over time you’ll knowthat your elevator is conserving what used to be wasted energyand helping in your effort to keep your building green.
SCR - For DC MotorsThey are still out there, elevators running with DC motors. Westill build elevator controllers for these types of applicationsutilizing a solid state SCR Drive. We also use PLC Based logic,encoder feed back and recommend you installing a new lineisolation transformer to ensure that noise and interference iskept to a minimum. There’s still a market for DC controllers, it’sjust not as large as for VVVF AC elevators.
Microprocessor Control (PLC) CJAutilizes the best software and PLC’s to achieve the bestperformance for your elevator. Each Control System has a“brain” which contains a non volatile memory program thatcannot be erased in the event of a power outage.
Microprocessor control allows CJA to upgrade programs in thefuture to allow for code changes and new elevator requirements.We also manufacture controllers using PLC’s that are industrialtype. One of the most popular among the ones we build with isAllen Bradley.
Relay Logic Need Relay Logic? We still make them. Keep in mind that theprice of a Relay based system when compared to aMicroprocessor based system is actually more due to anincreased number of relays and time involved withmanufacturing and testing the controller. Also note that certainFire Service Codes are not available with this type of logic, andSingle Automatic Pushbutton operation can only beaccommodated with elevators over three floors. Ideal forelevator speeds under 100 Feet Per Minute and using motorcontrols that are anything but VVVF. Perfect in some cases forlike for like repair replacements.
Touchscreen DiagnosticsCJAMicroprocessor control systems come equipped with touchscreen controls for monitoring the elevator and reporting faultsof the system, such as bad door interlock contacts. Each LCDscreen is easy to navigate through and also allows the mechanicthe ability to change simple parameters such as door timing andalternative floor for fire service. This is a standard feature on allPLC based controllers.
Easy to Wire Terminal BlocksEasy to view and wire terminal blocks make wiring a breeze.We specifically use easy to wire blocks to help with wiring.
Controller Air Conditioners & HeatersWe can upon request provide cabinet cooled air conditioners toprevent damage to both microprocessor and solid state motorcontrols for excessively hot machine rooms. Available inNEMA 1, 4/12 and 4X, we can easily provide them should yourequire one. Each unit is wired directly in to the control systemand comes with a manually adjusted thermostat. Heaters arealso available for colder climates as well.
Motor ControlConstant Pressure, Car Switch, Single Speed, Two Speed,Hydraulic, Variable Frequency Variable Voltage or DC SCRApplications. We can manufacture your controller for anyhorsepower or elevator speed you need. This is dependent uponwhat type of system you have.
These are just a few of the many features available to you whenyou purchase a CJA Control System. Each control system isbuilt to your job specifications and tested prior to shipping. Call today for controller pricing on your next project.
