Mains ROCOF
The module detected that the mains frequency had changed at a
rate larger then the Mains ROCOF Alarm Trip level when the
generator was in parallel with the mains.
Mains Under Positive
Sequence
The module detected the mains voltage positive sequence had fallen
below the configurable Trip level for the configured delay timer.
Mains Vector Shift
The module detected that the mains voltage waveform’s vector had
shifted more then the Mains Vector Shift Alarm Trip level when the
generator was in parallel with the mains.
MSC Failure
That module detected that the MSC communication failed, most
likely caused by it being disconnected.
MSC ID Error
The module detected that another module on the MSC link had the
same GenSet MSC ID configured.
MSC Old Version Unit

NOTE: For further details, refer to DSE Publication:
056-047 Out of Sync and Failed to Close Training Document.
If the module detects that the mains supply is not sync when the
