Operation

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.

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.

Automatic Operation Sequence

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).

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

To set the exercise timer:

NOTICE

The generator is set with a default exercise cycle

setting of Tuesday at 2:00 P.M, Central Time. To change the

cycle setting, proceed to the following steps:

1. Choose the day and time you want your generator to

exercise.

2. Press and hold the left arrow and right arrow

simultaneously for 3 seconds to enter the General

Set-Up program mode. See

General Set-Up

flow chart

in Menu Section.

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

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

button.

NOTICE

Items will flash until they are selected.

Setting Exercise Timer

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.

SELECT MINUTE: Use the left of right arrow to toggle

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.

NOTICE

During the weekly exercise cycle, the generator will

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