1. PLC Network Features
1.2. System requirements
The PLC network is read by EMS10, and the tariff shifting times of PLC/Router modules are also updated from EMS10.
Data between EMS10 and the PLC/Router module requires set-up of a PLC Concentrator and a PLC Single Router, if necessary. Planning is made in cooperation with Kamstrup.

The PLC Network consists of several components as illustrated in below system overview.
The PLC/Router module is installed in Kamstrup meters and collects registers, load profiles and events such as voltage cutoffs. These data are transmitted via the low-voltage mains network to a PLC Concentra-tor, from which data is transmitted to the utility company’s reading systems e.g. via GSM.
The PLC/Router module and the PLC Concentrator communicate on one single phase, and the capaci-tive coupling between the phases is utilized to transmit data irrespec-tive which phase the PLC/Router module is actually connected to. On top of that transmission of data is stable due to the FSK modula-tion.
In certain cases it might be expedi-ent to amplify the signals by means of a PLC 3 Phase Cover or a PLC Single Router.
Measuring data from a PLC/Router module placed far away from the PLC Concentrator can be transmit-ted via other PLC/Router modules. On installation, each PLC/Router creates its own local list consis-ting of a list of a signal/noise ratio between the module and the other PLC/Router modules, to which contact can be established immedi-ately. The local lists form the basis for determination of the optimal reading of all PLC/Router modules, in a so-called net list that is created in the PLC Concentrator.

3. Installation and commissioning
OBS: Please note that installation and commissioning may pose a poten-tial shock hazard (230 V). Installa-tion and commissioning should be made by authorised personnel only.
3.1. Installation of PLC Concentrator
The PLC Concentrator can be installed as a single component solution, where the PLC Concentra-tor inclu-ding an integral GSM5i modem can be installed in a typical 10/0.4 transformer station. Alternatively, a total solution of both PLC Concentrator and RF Concentra-tor can be installed in a temperate and protective cabinet with external antennas. This solution is outlined below, here combined with a RF Concentrator and a GSM Modem 3.
PLC Concentrator
Connection diagram
The RF PLC Concentrator Box has fixtures to ensure safe mounting on poles.
Supply to the RF OPLC Concentrator Box is lead through the bottom of the box (see draft overleaf), max 95 mm2.
Adjust the thermostat to the opera-ting temperature required.
Correct mounting direction is shown on the sketch (DIN-rail with heating element, thermostat and multicell switch below).
Special wall fixtures must be used for mounting on walls.

3.2. Commissioning PLC Concentrator
Before commissioning it ought to be checked that the GSM5i module is correctly mounted, that it includes a SIM-card, and that voltage has been connected. In addition, we refer to the instructions for GSM5i.
PLC Concentrator has a pushbutton and three light-emitting diodes (LED) at the top.
Keep the pushbutton pressed and release it again when the left LED begins to emit light. The LED goes out briefly and starts to emit light again to indicate that a connected GSM modem (external or integrat-ed) has obtained contact with the GSM network, and the two remain-ing LEDs start blinking. If the first LED remains off, this can mean that there is no contact between PLC Concentrator and the GSM Modem or between the GSM modem and the network.
Subsequently PLC Concentrator starts updating its local list. The two LEDs furthest to the right indi-cate the signal conditions to other Kamstrup PLC units: one LED is OK, two LEDs are best.
When all LEDs go out again com-missioning has been completed.
3.3. Installation of the PLC/Router
If the module is mounted in the electricity meter on delivery, please go to the paragraph concerning “Commissioning”. If not, please follow below directions:
Switch off the supply voltage to the electricity meter
Remove the top cover and install the module (please note that the 6 pins on the module obtain full contact)
Connect the supply and signal cables as stated in paragraph 3.3.1 to 3.3.2.
Connect the supply voltage to the electricity meter
Mount the top cover (if required, this can be done after commis-sioning, see paragraph 4.2).
Following paragraph states correct connection of the PLC/Router module depending on the meter type in which the module is to be installed.

3.4. Commissioning of the PLC/Router Module
Before commissioning check that the module has been correctly mounted and that voltage has been connected.
In the middle of the PLC/Router module there is a pushbutton and at the top of the module there are three light-emitting diodes (LED).
As soon as supply voltage has been switched on the module will automatically start an initialization routine, during which the left LED is constantly lighted for 5–10 seconds (if not, press the pushbutton on the module and release it again when the left LED starts emitting light).
The LED goes out for a short period. When the LED starts emitting light again, the module has carried out its initialization correctly. If, on the other hand, it does not start emit-ting light again or it starts flashing quickly an error has occurred and the installation must start from the beginning.
3.5. PLC/Router modul service
In the middle of the PLC/Router module there is a pushbutton and at the top of the module there are three light-emitting diodes (LED).
Start initialization by pressing the pushbutton until one of the below functions have been obtained. If the pushbutton is not released until all LEDs have gone out none of the below functions will be carried out.
Keep the pushbutton down until LED1 is lightedThe module initializes itself and communicates with the meter.
If OK, LED1 is lighted and the mod-ule creates a local list.
If it detects another router with signal strength 15, the second diode is lighted.
If it detects another router with signal strength 35, the third diode is lighted.
Keep the pushbutton down until LED1 and LED2 are lightedThe router sends a notification.
Keep the pushbutton down until all three diodes are lightedThe router’s local list is indicated in the form of a “flash code”
a long flash means 10
a short flash means 1
I.e. one long and two short flashes mean that the module’s local list consists of twelve units.
LED2 shows the number of routers in the local list
LED3 shows the number of concen-trators in the local list

3.6. Installation of PLC Single Router
A PLC Single Router ist used if com-munication is not robust enough to secure stable reading due to dis-tance or signal/noise ratio between two PLC/Routers or between a PLC/Concentrator and a PLC/Router.
3.7. Commissioning of the PLC Single Router
Before commissioning check that the router has been correctly mounted and that voltage has been connected.
PLC Single Router has a pushbut-ton and three light-emitting diodes (LED) at the top.
Press the pushbutton and release it again when the left LED starts emitting light. The LED goes out for a short period and when it starts emitting light again the two other LEDs start flashing. The PLC Single Router now starts to update its lo-cal list. The two LEDs furthest to the right indicate the signal conditions to other Kamstrup PLC units: one LED is OK, two LEDs are best.
When all LEDs go out again, com-missioning (i.e. updating the local list) has been finished.

4. Data in the PLC/Router Module
The PLC/Router module is furnished with a data logger in which daily and monthly values, load profiles and events are stored.
All registers and data are reset when the module detects a new electricity meter (e.g. in connection with new installations or meter replacements).
4.1. Daily logger/ Monthly logger
The daily/monthly logger consists of registers including tariffs and status information concerning the real time clock, among other things.
Daily logger values are stored at midnight (at 00:00), and monthly logger values every month (at 00:00).
The logging depth is 45 days and 45 months respectively.
Please note that daily and monthly loggers cannot be activated at the same time.

4.3. Event logger
The event logger (or incident logger) consists of status information con-cerning the real time clock, among other things. Status information is stored after each modification, e.g. adjustment of time. Among other things, the time adjustment is used to determine the duration of a voltage cutoff, 2 minutes being the least recordable cutoff.
The logging depth is 64 events.

Monday – Friday 1 shift/day 1 shift/day
Saturday – Sunday 1 shift/day 1 shift/day
It is possible to have 2 shiftings within 60 minutes.
Example:
Definition of tariff 2: 1 January – 31 December, Monday – Friday, 8 a.m. to 4 p.m.
To this should be added 30 op-tional days where low tariff can be active.
