Section 3 — Operation

Air-cooled Generators

4.Use the manual transfer handle inside the trans- fer switch to move the main contacts to their STANDBY position, i.e., loads connected to the standby power source (Figure 3.2).

5.To crank and start the engine, set the AUTO/OFF/ MANUAL switch to MANUAL.

6.Let the engine stabilize and warm up for a few minutes.

7.Set the generator’s main circuit breaker to its ON (or CLOSED) position. The standby power source now powers the loads.

Figure 3.2 – Manual Transfer Switch Operation

‹3.4.2 TRANSFER BACK TO UTILITY POWER SOURCE

When utility power has been restored, transfer back to that source and shut down the generator. This can be accomplished as follows:

1.Set the generator’s main circuit breaker to its OFF (or OPEN) position.

2.Let the engine run for a minute or two at no-load to stabilize the internal temperatures.

3.Set the generator’s AUTO/OFF/MANUAL switch to its OFF (or OPEN) position. The engine should shut down.

4.Check that utility power supply to the transfer switch is turned OFF.

DANGER

Do not attempt to activate the transfer switch manually until all power voltage supplies

to the switch have been positively turned off. Failure to turn off all power voltage supplies may result in extremely hazardous and possibly fatal electrical shock.

5.Use the manual transfer handle inside the trans- fer switch to move the main contacts back to their UTILITY position, i.e., loads connected to the util- ity power source (Figure 3.2).

6.Turn ON the utility power supply to the transfer switch using the means provided.

7.Set the system to automatic operation as outlined in Automatic Transfer Operation section.

3.5SETTING THE EXERCISE TIMER

This generator is equipped with an exercise timer. Once it is set, the generator will start and exercise once every seven days, on the day of the week and at the time of day the following sequence is completed. During this exercise period, the unit runs for approx- imately 12 minutes and then shuts down. Transfer of loads to the generator output does not occur during the exercise cycle unless utility power is lost.

A switch on the control panel (see Figure 3.1) per- mits selection of the day and time for the system to exercise. At the chosen time, perform the following sequence to select the desired day and time of day the system will exercise. Remember seasonal time changes affect the exercise time settings.

1.Verify that the AUTO/OFF/MANUAL switch is set to AUTO.

2.Press and hold the "Set Exercise Time" switch for several seconds, then release. All the red LED's will flash for approximately 10 seconds and then stop.

3.Once the red LED's stop flashing, the generator will start and run for approximately 12 minutes and then shut down. The exerciser is now set to run at this time of day each week.

Example: If the "Set Exercise Time" switch is pressed on Saturday afternoon at 2:00 p.m., the generator will start and exercise for approximate- ly 12 minutes every Saturday at 2:00 p.m..

NOTE:

The exerciser will only work in the AUTO mode and will not work unless this procedure is per- formed. The exerciser will need to be reset every time the 12-volt battery is disconnected and then reconnected, and when the 15A fuse is removed.

The 16kW unit has a low speed exercise option. Dip switch 1 on the control board is factory set to OFF. This allows the engine to run at a slower speed dur- ing weekly exercise periods for quieter operation. If this Dip switch is set to ON, the generator will exer- cise at it's normal speed.

This DIP switch position is only read at board power up. If the DIP switch position is changed, power to the board must be cycled for the micro controller to recognize the new DIP switch position.
