The definitions below describe the controls and functions
of the Generator/Engine Control Panel (Figure 11).
1. Fuel Leak Alarm Lamp — This lamp turns on when
the fluid in the containment is higher than the allowable
level.
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. Frequency Meter — Indicates the output frequency
in hertz (Hz). Normally 60 Hz
5. AC Ammeter — Indicates the amount of current the
load is drawing from the generator per leg selected by
the ammeter phase-selector switch.
6. AC Voltmeter — Indicates the output voltage present
at the U,V, and W Output Terminal Lugs.
7. Voltage Regulator Control — Allows ±15% manual
adjustment of the generator's output voltage.
8. 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.

9. 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.
10. Emergency Stop Switch Button — In the event of an
emergency press this button to shut down the generator.
This switch is an option on the DCA3000SSJU4F2.
On DCA300SSJU4F3 models S/N 9110376 and above
this switch is located on the outside of the enclosure.
11. Hour Check Button — With the engine stopped, press
and hold ths button. The total running hours, fuel level,
and battery voltage will be displayed.
12. Auto/Start Switch — This switch selects either manual
or automatic operation. Center position is OFF (reset).
13. Engine Speed Switch Switch — This switch controls
the speed of the engine low or high.
14. Voltage Change-Over Board — 6 jumper plates that
allows the generator to be configured for either 3Ø,
240 or 480 VAC output.
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.
