Alarm
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 but 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-energizes 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.
Note: 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.
To remove the fault of the latching alarms, refer to
Note: The LCD backlight is on if the unit has sufficient voltage while the unit is turned on, unless the unit is cranking,
for which the backlight is turned off.
If the controller is left in Stop mode without pressing any buttons for 30 minutes, the controller enters Power Save
mode. To 'wake' the controller, press the Stop/Reset (O) button.
AUTO MODE
This button will place the unit into Auto mode. This mode allows the generator to operate fully automatic, starting
and stopping as required with no user intervention.
MANUAL/START MODE LED
This LED will be lit when the unit is in Manual mode.
MANUAL/START MODE
This button will start the engine and place the unit in Manual mode, provided there are no shutdown errors, and the
engine satisfies the start status.
STOP/RESET MODE
This button will shut down the unit and put the controller into Stop mode, whether the controller is in Manual mode
or Auto mode.

The measured current has risen above the configured trip level for a
configured duration.
The measured current has fallen below the configured trip level. This is
used to detect lamp failure.
