3.6AUTOMATIC OPERATION

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.

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 switched 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.

•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.

3.8CONTROL BOARD DIP SWITCH

SETTINGS

Located on the control board is an eight position DIP switch (see Figure 3.2). The eight different switches, are used to configure the control board for the spe- cific engine and governor being used and are pre-set at the factory.

On the day, and at the time of day chosen for the generator to exercise, set the weekly exercise cycle as follows:

1.Place the AUTO/OFF/MANUAL switch in the AUTO position (Figure 3.3).

2.Press and hold the “Set Exercise Time” switch for five 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.

TO SET EXERCISER TIME

1)PLACE AUTO/OFF/MANUAL SWITCH TO AUTO POSITION.

2)HOLD "SET EXERCISE TIME" SWITCH IN "ON" POSITION FOR THREE SECONDS AND RELEASE. (SEE OWNER'S MANUAL FOR COMPLETE DETAILS)

THE EXERCISER IS NOW SET. ALL FIVE RED LED'S WILL FLASH FOR 10 SECONDS

THEN THE UNIT WILL START, RUN THROUGH THE EXERCISE CYCLE AND SHUTDOWN.

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 the DIP switch settings are not set correctly, the generator may not start or operate correctly.

240 VAC can be present within the control panel.

If it is necessary to select an alternate switch posi- tion, move the AUTO/OFF/MANUAL switch to the OFF position. Remove the 15 amp fuse in the genera- tor control panel. Move the DIP switch position that needs to be changed to its new position. Wait five seconds, then re-install the 15 amp fuse.

The ON position is marked on the switch and is shown in Figure 3.2.

Switch Position 1 — Selects the generator alternator output frequency and is factory pre-set for 60 Hz.

Switch Position 2 — Selects the type of transfer switch and is factory pre-set for an automatic trans- fer switch (ATS).

Switch Position 3 — Selects the type of governor control used, and is factory pre-set for stepper motor operation.

Switch Position 4 — Selects the type of fuel being used and is factory pre-set for natural gas (NG).

Switch Position 5 — Selects the engine displacement and is factory pre-set for a 2.5 liter (2.5L) engine.

Switch Position 6 — Selects the number of engine cylinders and is factory pre-set for four cylinders.

Switch Position 7 — Selects the direction of rotation of the governor stepper motor and is factory pre-set for CCW rotation (rotation is observed looking at the stepper shaft as it moves from closed throttle to open throttle).
