GENERATOR CONTROL PANEL
The definitions below describe the controls and functions of
the DCA-180SSJU
(Figure 7).
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.
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.
Voltage Regulator Control –
Allows ±15% manual
adjustment of the generator’s output voltage.
5.
AC Voltmeter –
Indicates the output voltage present at
the .
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.
Main Circuit Breaker –
This three-pole, 500A main
breaker is provided to protect the the
from overload.
Located behind the generator control panel is the
. 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:

Remember the
monitors the current
flowing from the
to the
load.
In the event of a short circuit or over current condition, it will
automatically trip the 500 amp main breaker.
To restore power to the
, press the
button on the overcurrent relay and place the
circuit breaker in the
position (
ON
).
