3.6 AUTOMATIC OPERATION

Figure 3.2 - “Set Exercise” Switch

To set the system for fully automatic operation, pro- ceed as follows:

Check that load circuits are connected to the utility power supply.

Set the AUTO/OFF/MANUAL switch to its AUTO position.

Set the generator main circuit breaker to its ON or CLOSED position.

3.7WEEKLY EXERCISE CYCLE

The engine control board will start and run the gen- erator once every seven days for approximately 12 minutes. If utility should fail during this exercise period, the engine control board will transfer the load to the generator output and continue to run until util- ity returns.

On the day, and at the time of day chosen for the gen- erator to exercise, set the weekly exercise cycle as fol- lows:

1.Place the AUTO/OFF/MANUAL switch in the AUTO position.

2.Press and hold the “Set Exercise” switch for three seconds, then release.

At this time all five red LEDs will flash for approxi- mately 10 seconds, then the engine will start and run for it’s 12 minute exercise period, then shut down. The generator will now start and run each week at the same time.

If DC power to the control board is lost, the weekly exercise setting will be lost. This is indicated by all five red LEDs continually flashing. In this state the generator will still start and run in manual mode, or automatically start and run if UTILITY is lost while in Auto mode, but it will not perform a weekly exercise cycle.

If a failure occurs while running in this mode, the five red LEDs will stop flashing, the individual fault LED will turn on and the engine will shut down. Once the AUTO/OFF/MANUAL switch has been switch to OFF, the individual fault LED will turn OFF and the five red LEDs will begin flashing to show exercise has still not been set.
