15. APPENDIX VI: CALIBRATION OF THE
CONTROL UNIT
The CEC7 control unit allows calibration adjustments to be made to the voltage
measurements of the genset and network (only control units CEA7 and CEC7).
For this purpose, it is enabled in the Parameters menuàMeasurements of
parametersà 3, 4 and 5 for calibrating the voltages R, S and T of the genset.
Also, parameters 14, 15 and 16 are enabled for calibrating the voltages U, V and
W of the network (only control units CEA7 and CEC7). To carry out this process,
the enabling of a manufacturer level password is required.

Pressing the key ücompletes the calibration process. The calibration process
can be interrupted by pressing the key û. Calibration of the system can be
reset by writing parameter 17 for the network voltage and parameter 18 for
the genset voltages.
