Figure 4. Generator Control Panel

The definitions below describe the controls and functions of the DCA45SSIU4 Generator Control Panel (Figure 4).

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

2.Main Circuit Breaker—This three-pole, 110A main breaker is provided to protect the the U,V, and W Output Terminal Lugs from overload.

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.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.

5.AC Voltmeter — Indicates the output voltage present at the U,V, and W Output Terminal Lugs.

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

7.Frequency Meter — Indicates the output frequency in hertz (Hz). Normally 60 Hz.

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 flowing 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 110 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).
