6.4 ELECTRICAL TRIP ALARMS
NOTE: The alarm condition must be rectified before a reset takes 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).
Electrical trips are latching and stop the Generator but in a controlled manner. On initiation of the
electrical trip 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 starts the
Cooling timer and allows the engine to cool off-load before shutting down the engine. The alarm must
be accepted and cleared, and the fault removed to reset the module.
Example
1/2 Alarms
Generator Overcurrent
Electrical Trip
Electrical trips 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.
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.
Expansion Unit Failure
The module detects the DSE Net link to the expansion module has
failed or communications to the expansion module has been lost.
Generator kW Overload
The measured kW has risen above the configured trip level for a
configured duration.
High Fuel Level
The level detected by the fuel level sensor is above the high fuel
level pre-set pre-alarm setting.
Low Fuel Level
The level detected by the fuel level sensor is below the low fuel
level pre-set pre-alarm setting.
