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. charging voltmeter gauge — 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. panel light — 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. panel light switch — When activated will turn on
control panel light.
4. pilot lamp — Indicates the system is active.
5. Frequency meter — 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.
7. ac voltmeter — Indicates the output voltage present
at the u,v, and W output terminal lugs.
8. voltage regulator control — Allows ±15% manual
adjustment of the generator’s output voltage.
9. ammeter change-over switch — This switch allows
the AC ammeter to indicate the current flowing to the load
connected to any phase of the output terminals, or to be
switched off. This switch does not effect the generator
output in any fashion, it is for current reading only.
10. voltmeter change-over switch — This switch allows
the AC voltmeter to indicate phase to phase voltage
between any two phases of the output terminals or to
be switched off.
11. emergency stop Button — Push this button inward
to stop the engine in the event of an emergency. dO
NOT use this button as a means of stopping the engine.
12. engine speed switch — This switch controls the
speed of the engine (low/high).
13. auto/start switch — This switch selects either manual
or automatic operation . Center position is OFF (reset).
14. hour check Button — With the engine stopped, press
and hold ths button. The total running hours, fuel level,
and battery voltage will be displayed.
15. main circuit Breaker — This three-pole, 800 amp
main breaker is provided to protect the u,v, and W
output terminal lugs from overload.
