For this example we assume that the following alarms have been triggered:
Signal fault SS83 : Remote start,
Signal fault LAL28 : Lube oil level low,
Signal fault ZS97 : Remote switch,
Signal fault LAH92 : OMD alarm,
Signal fault TAH 29-27 : CCMON alarm,
Signal fault : Emergency generator mode,
Signal fault : Switch isochronous / droop mode
