The defi nitions below describe the controls and functions
of the DCA125SSIU Generator Control Panel (Figure 4).
Main Circuit Breaker
1.
—This three-pole, 300A main
breaker is provided to protect the the U,V, and W Output
Terminal Lugs from overload.
Voltage Regulator Control
2.
— Allows ±15% manual
adjustment of the generator’s output voltage.
Ammeter Change-Over Switch
3.
— This switch allows
the AC ammeter to indicate the current fl owing 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.
Voltmeter Change-Over Switch
4.
— 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.
Frequency Meter
5.
— Indicates the output frequency
in hertz (Hz). Normally 50 Hz.
AC Ammeter
6.
— Indicates the amount of current the
load is drawing from the generator per leg selected by
the ammeter phase-selector switch.
AC Voltmeter
7.
— Indicates the output voltage present
at the U,V, and W Output Terminal Lugs.
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
fl owing 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 300 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
).
