2. Introduction This second generation microprocessor module, created by C.R.E., is a module for manual coupling which integrates a synchronisation column and the syncheck authorisation relay. The synchronisation column allows visualisation of phase, frequency and voltage difference between one or several gensets to be coupled to a bus bar or reference bus. The authorisation relay allows safe coupling only when the conditions meet the requirements of the installation. This new version of C2S features the following functions:     CE mark conformity, thanks to a new electronic and mechanical...

Putting into service The Synchronisation and Safety Column (C2S) is powered by the generator voltage on Vgen terminals 4 and 5. WARNING : The module C2S is powered from 60% of nominal generator voltage value, and up to 115% as a maximum. Not damage the C2S, Voltage must not exceed 115%. 3.2 Auto/Manual Mode The bargraphs and signalling of the C2S module function as follows:  In manual mode (terminals 6-7 open), all the displays and functions are in order. The "AUTO" LED is not lit.  In automatic mode (terminals 6-7 closed), the synchronoscope and the 2 differential bargraphs (voltmeter and...

3.4 Micro-shunts The micro-shunt JP1 configures the C2S to authorise the closure of the output relay when no voltage is present on the bus and the generator voltage is correct (between 85% and 115% of the nominal value). The JP2 micro-shunt allows a self-test of all the module's LEDs when the system is powered up. Chapitre : Operation WARNING : The LEDs test lasts approximately 8 seconds.

4. Configuration - Factory settings To access potentiometers and micro-shunts, it is necessary to remove the back cover of the module. WARNING : Check that no voltage is present on the terminal trip before removing the cover. Note : The RV1 potentiometer is factory configured and should not be altered. - RV2 "phase difference" Potentiometer: This potentiometer enables the adjustment of the allowed phase difference between +/-5° (fully counter-clockwise) and +/-20° (fully clockwise). Factory setting 10°. - RV3 "voltage difference" Potentiometer: This potentiometer enables the adjustment of the...

5. Putting into service – Control - Disconnect the wires from the coupling authorisation relay's isolated contact (terminals 8-9), so as to prevent the coupling of the generator with the bus. - Feed the C2S module with generator voltage Vgen, on terminals 4 and 5. Generator voltage to be coupled and the bus voltage should both be present. - Check the relationship between the phases applied in VGEN (terminals 4-5) and VBUS (terminals 2-3) on the C2S 2 opposite phases generate a 180° coupling. Different phases on VGEN and VBUS generate a +/-120° coupling. - Check that the voltage presence LEDs...

6. EMC precaution - CE mark conformity The C2S version A25Zx is conformed to European CE mark requirements. Here below some tips to use the C2S. - Faraday cage effect: The C2S is painted with a conductive paint. We recommend maintaining surface contact between the C2S casing and the switchboard housing. If the back cover needs to be removed, replace it and screws must be fully tightened. Chapitre : EMC precaution - CE mark conformity For IP65 protection use a gasket (preferably conductive to ensure EMC). For more details about the positioning and the dimensions (in mm) of the gasket, refer to...

WARNING : Check carefully that the phases connected on the generator voltage are the same as those connected on the reference bus voltage and in the same order. Remember that 2 opposite phases generate a 180° coupling and that different phases on the generator voltage and the bus voltage generate a +/-120° coupling. C2S – CRE Technology – Official Technical documentation Chapitre : WIring Diagram The voltage VGEN of the generator to be coupled is connected by 2 wires on terminals 1 and 2. The voltage VBUS of the reference bus is connected by 2 wires on terminals 3 and 4. If the supplying voltages...
