Figure 5. Generator Control Panel

The definitions below describe the controls and functions of the Generator Control Panel (Figure 5).

1.Main Circuit Breaker—This three-pole, 90A main breaker is provided to protect the the U,O, and V Output Terminal Lugs from overload.

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

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

6.AC Voltmeter — Indicates the output voltage present at the U,O, and V 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:

„„Over-Current Relay

„„Automatic Voltage Regulator (AVR)

„„Starter Relay

„„Current Transformer

„„Engine Controller
