Operation

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.

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 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.
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.
NOTICE Items will flash until they are selected.
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.
