Alarms
GC1100 controller allows to configure several Shutdown/Electrical trip, Warning and Notification alarms
such as Low Oil Pressure Shutdown, Over Load Warning and many more.
An alarm condition occurs when the preconfigured parameter is out of pre-set level. On initiation of an
alarm, the Alarm LED will start blinking and Sounder alarm will be activated if configured. The controller
will display name of alarms along with count on ALARMS screen and the nature of alarm on ENGINE
STATUS screen. For acknowledging the alarms, press “UP + DOWN” keys simultaneously. All the
alarms have activation from Engine ON i.e. after crank disconnect or Monitoring ON i.e. after
completion of safety monitoring timer or Always. The controller will not issue the start command if the
Warning, Electrical trip or shutdown alarm left unacknowledged.
