Engine/Generator Control Panel - MQ Power WHISPERWATT Series Operation Manual

The definitions below describe the controls and functions
of the Engine/Generator Control Panel (Figure 5).
1. Engine Warning LEDs — There are six engine
warning lamps, they are defined as follows:
A. Engine Shutdown LED— Indicates that the
engine has shut down due to an engine failure.
LED will turn ON.
B. Engine Pre-Alarm LED — Indicates that an
engine failure has occured. LED will turn ON or
blink.
C. Battery Charge Alarm LED — This LED is ON
when the output voltage of the alternator drops
below a set value. If this lamp is on during normal
operation, the emergency shutdown system will
immediately stop the engine.
D. Fuel Filter Water Level LED — This LED is
ON when the water level in the fuel filter is
extraordinarily high.
E. Fuel Leak Detected Lamp LED — This LED is
ON when the fluid in the containment is higher than
the allowable level.
F. Pre-Heat LED — The pre-heat LED will be
ON during the pre-heating cycle (cold weather
conditions). When the pre-heat cycle is completed
the LED will turn OFF and the engine can be
started.

2. Auto START/STOP Controller (CAN 78) — This
controller has a vertical row of status LEDs (inset), that
when lit, indicate that an engine malfunction (fault) has
been detected. When a fault has been detected, the
engine controller will evaluate the fault and all major
faults will shut down the generator. During the cranking
cycle, the ECU will attempt to crank the engine for
10 seconds before disengaging.
If the engine does not engage (start) by the third
attempt, the engine will be shut down by the engine
controller's Over Crank Protection mode. If the engine
engages at a speed (RPM) that is not safe, the
controller will shut down the engine by initializing the
Over Speed Protection mode.
The engine controller will also shut down the engine in
the event of low oil pressure, high coolant temperature,
low coolant level, and loss of magnetic pickup. These
conditions can be observed by monitoring the LED
status indicators on the front of the controller module.
