automatic operation
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.
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).
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 deservice code 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 three 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.

Utility Voltage Pickup Sensor
This sensor monitors utility 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 back 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.
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.
