2.2 SHUTDOWNS
Shutdowns are latching and stop the Generator. The alarm must be accepted and cleared, and the
fault removed to reset the module.
In the event of a shutdown alarm the LCD will display:-
The COMMON ALARM LED will also illuminate (Red Flashing). The appropriate LCD icon will also
be displayed flashing
NOTE:- The alarm condition must be rectified before a reset will take place. If the
alarm condition remains it will not be possible to reset the unit (The exception to this is the
Low Oil Pressure alarm and the like, as the oil pressure will be low with the engine at rest).
Any subsequent warnings or shutdowns, which occur, will be displayed steady, therefore
only the first-up shutdown will appear flashing.
FAIL TO START, if the engine does not fire after the pre-set number of attempts has been made a
shutdown will be initiated. The LCD will indicate:-
The COMMON ALARM and LED will flash (Red).
EMERGENCY STOP, removal of the +ve DC Supply from the Emergency Stop input initiates the
following sequence, firstly it will initiate a controlled shutdown of the Generator and prevent any
attempt to restart the Generator until the Emergency Stop push-button has been reset. Secondly it
removes the +ve DC supply from both the Fuel Solenoid and Starter Solenoid. The LCD will
indicate:-
The COMMON ALARM LED will flash (Red).
NOTE:- The Emergency Stop +Ve signal must be present otherwise the unit will
shutdown.

oil pressure trip setting level after the Safety On timer has expired, a shutdown will occur. The
LCD will indicate:-
The COMMON ALARM LED will flash (Red).
HIGH ENGINE TEMPERATURE, if the module detects that the engine coolant temperature has
exceeded the high engine temperature trip setting level after the Safety On timer has expired, a
shutdown will occur. The LCD will indicate:-
The COMMON ALARM LED will flash (Red).
OVERSPEED, if the engine speed exceeds the pre-set trip a shutdown is initiated. The LCD will
indicate:-
The COMMON ALARM LED will flash (Red). Overspeed is not delayed, it is an immediate
shutdown.
