Auto Start/Stop Controller (ECU 750) — This
controller has a vertical row of five status LED’s, 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 shutdown the generator. During
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 shutdown by the engine
controller’s
Over Crank Protection mode. If the
engine engages at a speed (RPM’s) that is not
safe, the controller will shutdown the engine by
initializing the
Over Speed Protection mode.
Also the engine controller will 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.
• Low Oil Pressure LED — This LED will light
when the engine oil pressure drops to 14.2 psi
(98 kPa). This condition will cause the engine
to shut down. This is considered a
major fault.
The definitions below describe the controls and functions
of the Engine Control Panel (Figure 7).

Gauge Unit Assembly — This assembly houses the
various engine monitoring gauges. These gauges
indicate: oil pressure, water temperature, charging
voltmeter, fuel and engine speed RPM (tachometer).
A.
Oil Pressure Gauge — During normal
operation this gauge should read approximately
50 psi. (345 kPa). When starting the generator, the
oil pressure may read a little higher, but after the
engine warms up the oil pressure should return to
the correct pressure range.
B.
Water Temperature Gauge — During normal
operation this gauge should read approximately
180°F (82°C).
C.
Charging Voltmeter Gauge — During normal
operation this gauge indicate minimum 14 VDC.
D.
Fuel Gauge — Indicates amount of diesel fuel
available.
E.
Tachometer — Indicates engine speed in RPM’s
for 60 Hz operation. This meter should indicate
1800 RPM’s when the rated load is applied.
