The controller will automatically return to this screen from any other screen after a period of inactivity.
Alarms Screen
The Alarms (
) screen(s) will display all the alarms, warnings, engine DTC alarms, and the trouble codes. When
an alarm occurs, the controller will automatically jump to this page and will not automatically leave it. The Stop LED
will also flash on and off.
Warnings are non-critical alarm conditions and do not affect the operation of the generator system, they serve to
draw the operator's attention to an undesirable condition. By default, warning alarms are self-resetting when the fault
condition is removed.
Electrical trips are latching and stop the generator in a controlled manner. On initiation of the electrical trip condition,
the controller de-energizes all the outputs, including the lights, to remove the load from the generator. Once this has
occurred, the controller starts the cooling timer and allows the engine to cool off-load before shutting down the engine.
Shutdown alarms are latching and immediately stop the generator. On initiation of the shutdown condition, the
controller de-energized all the outputs, including the lights, to remove the load from the generator. Once this has
occurred, the controller shuts the generator set down immediately to prevent further damage.
Diagnostic Trouble Codes (DTC) alarms are detected by the engine ECU and displayed by the controller.
