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.ACVoltmeter – 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:

■Over-Current Relay

■Voltage Rectifer (AVR)

■Starter Relay

■Current Transformer

■Voltage Selector Switch

■Three Phase Circuit Breaker

Remember the

NOTEmonitors 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).
