Voltage Regulator Adjustment | Generac Power Systems 004916-0

Section 3 — Operation

With the generator running and loads powered by generator AC output, turn ON the utility power supply to the transfer switch. The following should occur:

•After about six seconds, the switch should transfer loads back to the utility power source.

•About one minute after retransfer, the engine should shut down.

Air-cooled 11 kW Generators

4.Run the unit for one hour at 25% rated load.

5.Run the unit for one hour at 50% rated load.

6.Run the unit for one hour at 75% rated load.

7.Run the unit for one hour at 100% rated load.

8.Turn ON the utility power supply to the transfer switch, which will allow the transfer switch to transfer back to utility power. The unit will con- tinue to run for one minute and then shut down.

2.6VOLTAGE REGULATOR

ADJUSTMENT

With the frequency between 60-60.5 Hertz, slowly turn the slotted potentiometer (Figure 2.1) until line voltage reads 247-252 volts.

NOTE:

The access panel on top of the control panel must be removed to adjust the voltage regulator.

Figure 2.1 – Voltage Adjustment Potentiometer

NOTE:

The voltage regulator is housed inside the gen- erator's control panel. The regulator maintains a voltage in direct proportion to frequency at a 2-to-

1ratio. For example, at 62 Hertz, line-to-neutral voltage will be 124 volts.

3.1BREAK-IN PROCEDURE

Once the unit has been installed and all electrical checks have been made, it is strongly recommended that the following “Break-in Procedure” be completed to ensure correct generator operation in the future.

1.Set the generator’s AUTO/OFF/MANUAL switch to AUTO.

2.Turn OFF the utility power supply to the transfer switch using the means provided (such as a utility main line circuit breaker).

3.The unit will start, and the transfer switch will transfer to standby.

9.Allow the unit to cool.

10.Set the generator's AUTO/OFF/MANUAL switch to OFF. Remove the 7.5A and 15A fuses from the generator control panel. Disconnect the battery cables as outlined in “General Hazards” (page 2).

11.Drain the oil and remove the oil filter. Replace the oil filter according to Section 4.4, “Changing the Oil Filter”. Replace the oil with synthetic oil as recommended in Section 4.3, “Changing the Engine Oil”.

12.Reconnect the battery cables as outlined in “General Hazards” (page 2) and insert the 5A and 15A fuses into the generator control panel. The generator is now ready for service.

3.2USING THE AUTO/OFF/MANUAL SWITCH (FIGURE 3.1)

3.2.1 “AUTO” POSITION

Selecting this switch position activates fully automat- ic system operation. It also allows personnel to start and exercise the engine every seven days with the set- ting of the exercise timer (see Section 3.5).
