DCA-56SPX — GENERATOR CONTROL PANEL
The definitions below describe the controls and functions of
the DCA-56SPX 
Generator Control Panel (Figure 6).
1.
Frequency Meter – Indicates the output frequency in
hertz (Hz). Normally 60 Hz.
2.
AC Ammeter – Indicates the amount of current the load
is drawing from the generator per leg selected by the
ammeter phase-selector switch.
3.
AC Voltmeter – Indicates the output voltage present at
the 
U,O, and V Output Terminal Lugs.
4.
Voltage Regulator Control – Allows ±15% manual
adjustment of the generator’s output voltage.
5.
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.
6.
Main Circuit Breaker – This three-pole, 250A main
breaker is provided to protect the the 
U,O, and V Output
Terminal Lugs from overload.
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
Voltage Rectifer (AVR)
Starter Relay
Current Transformer
Voltage Selector Switch
Single Phase Circuit Breaker
Figure 6. Generator Control Panel
Remember the 
overcurrent
relay monitors the current
flowing from the 
U,O and V
Output Terminal  Lugs to the
load.
In the event of a short circuit or over current condition, it will
automatically trip the 250 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).
