Figure 6. Generator Control Panel

The definitions below describe the controls and functions of the DCA-20SPX 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, 90A main breaker is provided to protect the the U,O, andV 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

Remember the overcurrent

NOTErelay 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 90 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).
