6.2.2.2 Electrical trip alarm icons
Electrical trips are latching and stop the light tower, but in a controlled manner. On initiation of the electrical trip condition the Lc1003™ module de-energises all the
‘Light Output’ outputs to remove the load from the light tower. Once this has occurred the Lc1003™ 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 Lc1003™ module.
Electrical trips are latching alarms and to remove the fault, press the STOP button on the Lc1003™ module.
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.
Display Description Reason
Engine High Temperature
The module detects that the engine coolant temperature has exceeded the high engine
temperature pre-alarm setting level after the Safety On timer has expired.
Low Fuel Level The level detected by the fuel level sensor is below the low fuel level setting.
Delayed Over Current The measured current has risen above the configured trip level for a configured duration.
Low Current
The measured current has fallen below the configured trip level. This is used to detect lamp
failure.
