Operation

Automatic Operation

The standby generator system constantly monitors utility
power voltage. When the utility power voltage drops below
a pre-set level, the controller will signal the engine to crank
and start, and then switch electrical loads to the generator.
When utility power voltage is restored above the pre-set
level, electrical loads are switched back to the utility and the
engine is signaled to shut down.
System operation is controlled and sequenced by sensors
and timers on the controller and transfer switch. The system
operation is not adjustable.

Utility Voltage Dropout Sensor

This sensor monitors utility power voltage. If utility power
voltage drops below approximately 70 percent of the nominal
supply voltage, the sensor energizes a 6-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 supply
voltage, a time delay begins 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 as
follows:
If the generator has been running more than 5 minutes, the
engine will continue to run for about 1 minute before shutting
down.
If the generator has run for less than 5 minutes, the engine
will continue to run until 5 minutes has elapsed before
shutting down.

Setting the Exercise Timer

The generator should run an automatic exercise cycle once
every seven days. During the exercise cycle, the unit runs for
approximately 20 minutes and then shuts down. Electrical
load transfer does not occur during the exercise cycle
(unless a utility power outage occurs).
The generator will only enter the exercise cycle if the unit is
set to AUTO mode.
The generator is shipped with a default exercise cycle setting
of Tuesday at 2:00 PM. To change this exercise cycle setting,
proceed with the following steps:
1. Choose the day and time desired for the generator to
run the exercise cycle.
2. On the system controller, 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 Screen.
3. Verify and/or set the time and date on the unit.
4. Go to the SET EXERCISE prompt and press the "OK"
button.
Each of the following items will flash until selected:
SELECT DAY: Use the left or right arrow to toggle to
the desired day, then press the "OK" button.
SELECT HOUR: Use the left or right arrow to toggle to
the desired hour (between 1 and 12), then press the
"OK" button.
SELECT MINUTE: Use the left of right arrow to toggle
to the desired minutes (between :00 and :59), then
press the "OK" button.
SELECT AM/PM: Use the left of right arrow to toggle
between AM and PM, then press the "OK" button.
During the weekly exercise cycle, the generator will run
for approximately 20 minutes but will not supply power to
the home. The in-home monitor will continue blinking the
GENERATOR READY green LED.
To turn off the generator exercise cycle, press the OFF
selection within the SELECT DAY menu and press OK. The
display will show EXERCISE CYCLE OFF.
