Controls

See the Operator's Manual for complete description of the
residential generator controls.

Operation

Automatic Operation Sequence

The generator's control panel houses a logic control circuit
board. This control board constantly monitors utility power
source voltage. Should that voltage drop below a preset
level, control board action will signal the engine to crank
and start.
When utility source 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 10 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 supply voltage. When that
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 the load is transferred back to the utility power
source, the engine cool-down timer starts timing.
• The timer will run for about one minute, then the
generator will stop.
• Minimum engine run time is 5 minutes.

Setting Exercise Timer

The residential generator is equipped with an exercise
timer that will start and exercise the system once every
seven days. During this 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).
A button on the control panel is labeled "Set Exercise"
(see System Control Panel). The specific day and the
specific time of day this button is pressed is programmed
into the control board memory. This date and time is then
used to automatically initiate the system exercise cycle. The
"SET EXERCISE" legend on the control panel will flash until
the set exercise cycle is set.
To perform the Set Exercise procedure:
1. Choose the day and time you want your residential
generator to exercise.
2. On that day and time, press and hold down the "Set
Exercise" button for three seconds.
NOTE: "SET EXERCISE" will flash until the button is
pressed for three seconds, then "SET EXERCISE" will
illuminate for 5 seconds, and finally turn off.
3. Seven days later the unit will then start and run it's
20 minute exercise cycle.
For example, if you press the "Set Exercise" button on
Sunday morning at 10:00 AM, the unit will run an exercise
cycle the following Sunday at 10:00 AM (+/- 1/2 hour).
NOTE: "Set Exercise" will only work if the unit is in
the AUTO mode and this exact procedure is followed.
The exerciser will need to be re-set if the 15 Amp fuse
is removed or changed, or if the 12 Volt DC battery
is disconnected.
If you want to change the day and time the unit exercises,
simply perform the "Set Exercise" procedure at the exact
weekday and time you want it to take place.

Installation Inspection

Before placing the generator system into service, inspect the
entire installation carefully.
Complete the "Installation Checklist" as you make the
inspection. Ensure all items have been filled-in and all
signatures have been obtained. Return the completed form
to your records department.
More detailed Operating, Maintenance and Troubleshooting
information is given in the Operator's Manual.
