Installation Manual

7.Normal no load frequency is 62.0 to 62.5 Hz. If adjustment is needed at no load, slowly rotate the governor adjustment nut (Figure 14) clockwise and/or counterclockwise until frequency is 62.0 to 62.5 Hz.

8.Turn the service disconnect to the transfer switch off. The transfer switch will connect to the generator after a short time delay.

9.Load generator to rated Natural Gas rating.

10.Connect an accurate frequency meter to the load side of the main circuit breaker (on the back of the control panel). Frequency should be above 57.0 Hz.

11.If frequency is below 57.0 Hz, slowly rotate the governor adjustment nut clockwise and/or counterclockwise until frequency is above 57.0 Hz.

12.Turn the service disconnect to the transfer switch on. The transfer switch will connect to the utility after a short time delay.

13.Set the AUTO/OFF/MANUAL switch to OFF.

14.After the engine has stopped running, reinstall the control panel wiring cover to the air intake guard.

15.Reinstall the air intake and control panel access doors.

16.Set the AUTO/OFF/MANUAL switch to AUTO.

The generator’s control panel houses a logic control circuit board.This control board constantly monitors utility power source voltage. Should that voltage drop below a preset level, control board action will signal the engine to crank and start.

When utility source voltage is restored above a preset voltage level, the engine is signaled to shut down.

The actual system operation is not adjustable and is sequenced by sensors and timers on the control board, as follows:

Utility Voltage Dropout Sensor

This sensor monitors utility source voltage.

If utility source voltage drops below about 70 percent of the nominal supply voltage, the sensor energizes a

6-second timer.The timer is used to ‘sense’ brown-outs.

Once the timer has expired, the engine will crank and start.

Utility Voltage Pickup Sensor

This sensor monitors utility power supply voltage.When that voltage is restored above 80 percent of the nominal source voltage, a time delay starts timing and the engine will go to engine cool-down.

Engine Cool-down Timer

When the load is transferred back to the utility power source, the engine cool-down timer starts timing.

The timer will run for about one minute, then the generator will stop.

Minimum engine run time is 5 minutes.
