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
“Resetting the Maintenance Alarms”
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 for a period of inactivity, the controller enters Power Save mode. To ‘wake’ the
controller, press the Stop (O) button.

Event Log Screen
The controller’s event log (
) displays a list of the last 15 record electrical trip or shutdown events and the engine
hours at which they occurred. Once the log is full, any subsequent electrical trip or shutdown alarms overwrites the
oldest entry in the log. Hence, the log always contains the most recent shutdown alarms.

The engine ECU has detected that the engine speed has risen
above its configured over speed alarm level.
Low Fuel Level
The engine ECU has detected that the engine’s fuel level has
fallen below its configured low fuel level alarm.
Battery Under/Over Voltage
The engine ECU has detected that the engine’s DC supply has
fallen below or risen above its configured alarm level.
