ENGINE/GENERATOR CONTROL PANEL
The definitions below describe the controls and functions
of the Engine/Generator Control Panel (Figure 5).
1. 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 be should read between 40 to 60 psi.
(276~414 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 be should read between 180°
and 225°F (82°~107°C).
C.  — During normal
operation this gauge indicate minimum 26 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.
2.  — For operation at night, panel light
illuminates control panel for ease of reading meters
and gauges. Make sure oanel light switch is in the OFF
position when light is not in use.
3.  — When activated will turn on
control panel light.
4. — Indicates the system is active.
5. — Indicates the output frequency
in hertz (Hz). Normally 60 Hz.

6. AC Ammeter — Indicates the amount of current the
load is drawing from the generator per leg selected by
the ammeter phase-selector switch.

output in any fashion, it is for current reading only.
10. — This switch allows
