The definitions below describe the readouts and functions
of the Gauge Unit Assembly (Figure 10).
1. ECU-670 Gauge Unit Assembly — This assembly
houses the various engine monitoring gauges. These
gauges indicate: oil pressure, water temperature,
charging voltmeter, generator load, fuel level, DEF
level and engine speed RPM (tachometer).
A. Oil Pressure Gauge — During normal operation,
this gauge should read approximately 44 psi.
(300 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 between 185°
and 207°F (85°~97°C).
C. Tachometer — Indicates engine speed in RPM's
for 60 Hz operation. This meter should indicate
1800 RPM's when the rated load is applied.

D. Battery Voltmeter Gauge — During normal
operation this gauge indicates a minimum 14 VDC.
E. Generator Load Gauge — Indicates the generator
load rate. It is recommended the load be above the
red area (20%) for maintaining sufficient exhaust
temperature.
F. Fuel Gauge — Indicates amount of diesel fuel
available. The red area in the gauge indicates a
low fuel level (20%).
G. DEF Gauge — Indicates amount of diesel exhaust
fluid available. The red area in the gauge indicates
a low DEF level (10%).
H. Exhaust System State Indicator Lamps — Lamps
illuminate when engine is at Exhaust System State or
DEF state. Refer to the maintenance section of this
manual for more detailed indormation.
I. Low fuel Warning LED — When ON (lit) indicates
that fuel level is low.
