DCA-70SSIU (60 Hz) — GENERATOR CONTROL PANEL
Figure 6. Generator Control Panel
The definitions below describe the controls and functions of the
1.Main Circuit Breaker – This
2.Frequency Meter – Indicates the output frequency in hertz (Hz). Normally 60 Hz.
3.AC Ammeter – Indicates the amount of current the load is drawing from the generator per leg selected by the ammeter
4.Ammeter
5.ACVoltmeter – Indicates the output voltage present at the U,V, and W Output Terminal Lugs.
6.Voltmeter
7.Voltage Regulator Control – Allows ±15% manual adjustment of the generator’s output voltage.
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
■Three Phase Circuit Breaker
Remember the overcurrent
NOTErelay 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 175 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).
