PAGE 20 — DCA-400SSV— OPERATION AND PARTS MANUAL — REV. #0 (04/19/06)
Figure 6. Generator Control Panel
8. Panel Light Switch – When activated will turn on control
panel light.
9. Voltage Regulator Control – Allows ±15% manual
adjustment of the generator’s output voltage.
10. Main Circuit Breaker – This three-pole, 1,000 amp
main breaker is provided to protect the the
U,V, and W
Output Terminal Lugs
from overload.
11. Auto On/Off Engine Controller (MPEC) –
This controller has a vertical row of status LED's (inset),
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 MPEC will attempt to
crank the engine for 10 seconds
before disengaging.
The definitions below describe the controls and functions of
the DCA-400SSV
Generator Control Panel
(Figure 6).
1. Pilot Lamp – Indicates the
2. Panel Light – Normally used in dark areas or at night
time. When activated, panel lights will illuminate. When
the generator is not in use be sure to turn the panel
light switch to the OFF position.
3. AC Voltmeter – Indicates the output voltage present at
the
U,V, and W Output Terminal Lugs
.
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. 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.
7. 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.
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.
