DCA-25USIXF/DCA-25USI2XF— GENERATOR CONTROL PANEL

Figure 6. Generator Control Panel

The definitions below describe the controls and functions of the "Generator Control Panel " (Figure 6).

1.Frequency Meter – Indicates the output frequency in hertz (Hz). Normally 60 Hz ±1 Hz.

2.Voltage Regulator Control – Allows ±15% manual adjustment of the generator’s output voltage.

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.Main Circuit Breaker – This three-pole, 60 amp main breaker is provided to protect the UVWO output terminals from overload.

5.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.

6.AC Voltmeter – Indicates the output voltage present at the UVWO terminals.

7.AC Ammeter – Indicates the amount of current the load is drawing from the generator per leg selected by the ammeter phase-selector switch.

Located behind the generator control panel is the Generator Control Box. This box contains some of the necessary electronic components required to make the genertator function.

The “Control Box” is equipped with the following major components:

Over-Current Relay

Voltage Rectifer

Starter Relay

Three Pole Circuit Breaker

Current Transformer

Voltage Selector Switch

Remember the overcurrent relay monitors the current flowing from the UWVO output terminals to the

NOTE load.

In the event of a short circuit or over current condition, it will automatically trip the main 60 amp breaker.

To restore power to the UWVO output terminals, press the reset button on the overcurrent relay and place the main circuit breaker in the closed position (ON).
