10. Alarms
10.1 Alarms
When a Shutdown alarm occurs the controller commands the genset to stop. The controller does not send the start command if the
Shutdown alarm is not acknowledged.
When an Electrical trip alarm occurs, the controller opens the genset contactor and then commands the genset to stop. The
controller does not send the start command if the Electrical trip alarm is not acknowledged.
If the Warning alarm occurs while the genset runs, the controller does not send the stop command. But if the Warning alarm is not
acknowledged when the genset is stopped, the genset cannot be started.
If Auto warning clear is enabled, the Warning alarms are automatically cleared when the conditions that triggered the alarm are
cleared.
