ta Fail
The module is configured for CAN
operation and does not detect data
on the engine CAN data link.

Electrical Trip Alarm Icons
Electrical trips are latching and stop the Generator but in a controlled manner. On initiation of the electrical
trip condition the module de-energises all the `Delayed Load Output' and the `Close Gen Output' outputs to
remove the load from the generator. Once this has occurred the module starts the Cooling timer and allows
the engine to cool off-load before shutting down the engine. The alarm must be accepted and cleared, and
the fault removed to reset the module.
Electrical trips are latching alarms and to remove the fault, press the STOP/RESET mode button on the module.
The alarm condition must be rectified before a reset will take place. If the alarm condition remains, it is not
possible to reset the unit (The exception to this is the Low Oil Pressure alarm and similar `active from safety
on' alarms, as the oil pressure is low with the engine at rest).
