6.5 SHUTDOWN ALARMS
NOTE: The alarm condition must be rectified before a reset takes place. If the alarm
condition remains, it is not be 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).
Shutdown alarms are latching and immediately stop the Generator. On initiation of the shutdown
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 shuts the generator set
down immediately to prevent further damage. The alarm must be accepted and cleared, and the fault
removed to reset the module.
Example
1/2 Alarm
Low Oil Pressure
Shutdown
Shutdowns are latching alarms and to remove the fault, press the Stop/Reset Mode
button on the
module.
Fault Description
Analogue Input A to D
The module detects that an input configured to create a fault
condition has become active and the appropriate LCD message is
displayed.
CAN ECU Data Fail
The module is configured for CAN operation and does not detect
data on the engine Can data link.
Charge Alternator Failure
The auxiliary charge alternator voltage is low as measured from
the W/L terminal.
Coolant Temperature Sensor
Fault
The module detects that the circuit to the coolant temperature
sensor has been broken.
Emergency Stop
The emergency stop button is pressed. This failsafe (normally
closed to emergency stop) input and immediately stops the set
when the signal is removed.
Delayed Over Current
The measured current has risen above the configured trip level for
a configured duration.
Digital Inputs A to F
The module detects that a digital input which has been user
configured to create a fault condition has become active and the
appropriate LCD message is displayed.
ECU Amber
The module detects that the engine ECU has detected a fault
causing an Amber alarm.
ECU After Treatment
The module detects that the engine ECU has detected that the
after treatment is currently in progress.
ECU Malfunction
The module detects that the engine ECU has detected a fault
causing a Malfunction alarm.
ECU Protect
The module detects that the engine ECU has detected a fault
causing a Protect alarm.
ECU Red
The module detects that the engine ECU has detected a fault
causing a Red alarm.
ECU Water In Fuel
The module detects that the engine ECU has detected that there is
water in the fuel.
