Generator Control Panel - MULTIQUIP Power WhisperWatt DCA45SSIU4 Operations & Parts Manual

MOOOOO-20001Q
The definitions below describe the controls and functions
of the DCA45SSIU4 Generator Control Panel (Figure 4).
1. voltage regulator Control — Allows ±15% manual
adjustment of the generator's output voltage.
2. main Circuit breaker—This three-pole, 110A main
breaker is provided to protect the the U,V, and W
Output Terminal Lugs from overload.
3. 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.
4. 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.
5. aC voltmeter — Indicates the output voltage present
at the U,V, and W Output Terminal Lugs.
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. Frequency meter — Indicates the output frequency
in hertz (Hz). Normally 60 Hz.

Located behind the generator control panel is the Generator
Control Box. This box contains some of the necessary
electronic components required to make the generator
function.
The Control Box is equipped with the following major
components:
„ Over-Current Relay
„ Automatic Voltage Regulator (AVR)
„ Starter Relay
„ Current Transformer
„ Voltage Selector Switch
„ Main Circuit Breaker
NOTICE
Remember the overcurrent relay monitors the current
flowing from the U,v, and W output terminal lugs
to the load.
In the event of a short circuit or over current condition,
it will automatically trip the 110 amp main breaker.
To restore power to the Output Terminal Panel, press
the reset button on the overcurrent relay and place the
main circuit breaker in the closed position (ON).
