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

1.  Voltage Regulator Control — Allows ±15% manual 

adjustment of the generator’s output voltage.

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 phase-selector switch.

4.  AC Voltmeter — Indicates the output voltage present 

at the U,V, and W Output Terminal Lugs.

5.  Ammeter Change-Over Switch — This switch allows 

the AC ammeter to indicate the current fl owing 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.  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.

7.  Main Circuit Breaker—This three-pole, 60A main 

breaker is provided to protect the the U,V, and W 
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

 

 Automatic Voltage Regulator (AVR)

 

 Starter Relay

 

 Current Transformer

 

 Voltage Selector Switch

 

 Main Circuit Breaker

Remember the overcurrent relay monitors the current 
fl owing 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 60 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).
