12.3.3. VERIFICATION
There is an incorporation of the menus MaintenanceàSynchronizationà
AmplitudeàTest and MaintenanceàSynchronizationàFrequencyàTest in order
to verify the correct operation of the synchronization process between network
and genset of the CEC7 control unit. To perform the synchronization verication
process, the following is required:
• Stable motor.
• Stable network signal.
• Open genset contactor.
Once the menu option has been selected the verication process begins while
the deviation is displayed between the network and genset signals (volts for
testing the amplitude synchronization and ‰ for the deviation of the frequency
synchronization). This process can take several minutes during which the
deviation between the network and genset signal is shown ashing indicating
that this deviation exceeds the synchronization threshold for amplitude or
programmed frequency in parameters 2 and 3 of the Synchronization table.

This process can take several minutes during which the current synchronization
coefcient values are shown ashing; if the deviation between the network and
genset signal is shown ashing, this indicates that the deviation exceeds the
synchronization threshold for amplitude or programmed frequency
(Synchronization table parameter 2 and 3).When the CEC7 control unit has found
synchronization coefcients values which adapt to the generator set response,
the value reached is shown lit. Once nished, it is possible to save or discard the
values obtained using the keys on the control unit.
