Automatic Operation Sequence

The generator’s control board constantly monitors utility voltage. Should utility voltage drop below a preset level, the control board will signal the engine to crank and start.

When utility 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 3 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 voltage. When utility 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 utility power is sensed and the load transfers to the utility source, the engine will go into a cool down period as described below:

• If the generator has run for MORE than 5 minutes, once the utility transfer occurs, the engine will continue to run for about 1 minute before shutting down.

• If the generator has run for LESS than 5 minutes, once the utility transfer occurs, the engine will continue to run until 5 minutes has elapsed before shutting down.

Setting Exercise Timer

The generator is equipped with an exercise timer. During the exercise period, the unit runs for approximately 20 minutes and then shuts down. Electrical load transfer DOES NOT occur during the exercise cycle (unless an utility power outage occurs).

SELECT DAY: Use the left or right arrow to toggle through the days of the week, Once the day is selected, hit the “OK” button.

SELECT HOUR: Use the left or right arrow to toggle through between 1 and 12. Choose the hour of day you want the generator to exercise then hit the “OK” button.

The generator will only enter the exercise cycle if the unit is in the AUTO mode and this exact procedure is followed.

4. Go to the SET EXERCISE prompt and hit the “OK” button.

To set the exercise timer:

between :00 and :59. Choose the minute of the day you want the generator to exercise then hit the “OK” button.

SELECT AM/PM: Use the left of right arrow to toggle between AM and PM. Once chosen, hit the “OK” button.

run for 20 minutes, but it will not supply power to the home.

During the exercise cycle, the in-home monitor will continue blinking the GENERATOR READY green LED.

3. Verify and/or set the time and date on the unit.

If you want to change the day and time the unit exercises, simply perform the procedure again.

NOTICE Items will flash until they are selected.

To turn off the generator exercise cycle, go to the OFF selection within the day of the week menu and press OK. The display will then scroll: EXERCISE CYCLE OFF.
