Figure 4. Generator Control Panel
The defi nitions below describe the controls and functions of the DCA125SSIU Generator Control Panel (Figure 4).
1.Main Circuit
2.Voltage Regulator Control — Allows ±15% manual adjustment of the generator’s output voltage.
3.Ammeter
4.Voltmeter
5.Frequency Meter — Indicates the output frequency in hertz (Hz). Normally 50 Hz.
6.AC Ammeter — Indicates the amount of current the load is drawing from the generator per leg selected by the ammeter
7.AC Voltmeter — Indicates the output voltage present at the U,V, and W Output Terminal Lugs.
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:
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 300 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).
