* Natural gas rating will depend on specific fuel but typical
derating of generator is between 10 to 20% off the LP gas
rating.
This generator is rated in accordance with UL (Underwriters
Laboratories) 2200 (stationary engine generator assemblies)
and CSA (Canadian Standards Association) standard C22.2
No. 100-04 (motors and generators).
AUTOMATIC OPERATION
To select automatic operation, do the following:
1. Set service disconnect or main distribution panel circuit
breaker that sends utility voltage to transfer switch to
ON.
2. Set generator’s main circuit breaker to ON position.
3. Set AUTO/OFF/MANUAL switch to AUTO.
Checking Automatic Operation
To check the system for proper automatic operation, proceed
as follows:
1. Turn OFF service disconnect or main distribution panel
circuit breaker sending power to automatic transfer
switch.
The generator will crank and start once the utility voltage
drops out and the sensor has timed out. Let the system go
through its entire automatic operation sequence.
2. With generator output supplying load, turn ON service
disconnect or main distribution panel circuit breaker that
supplies utility power to automatic transfer switch.
3. Automatic transfer switch will transfer loads back to
utility power after five minute minimum run time and
utility is restored.
4. Generator will run for approximately an additional minute
for engine cool down, then shut down.
5. Install control panel access door and roof following
instructions in Removable Roof and Access Door.
NOTE: If generator does not shut down after approximately
10 minutes, put AUTO/OFF/MANUAL switch to OFF and
contact your local service center.
This completes the test procedures for automatic operation.
The Home Standby Generator will now start automatically
when utility power is lost and will supply power to the
transfer switch.
Servicing the System
To service system:
1. Remove roof by removing four screws and lifting off.
2. Remove screw at top of control panel access door.
3. Pull access door outward (away) from unit while pulling
door upward and out of base. Door will come free of
generator enclosure.
4. Set AUTO/OFF/MANUAL switch to OFF.
5. Set generator’s main circuit breaker to OFF position.
6. Pull service disconnect from disconnect box.
7. Remove 15A fuse from control panel.
FAULT DETECTION SYSTEM
The generator may have to run for long periods of time with
no operator present. For that reason, the system is equipped
with sensors that automatically shut down the generator in
the event of potentially damaging conditions, such as low oil
pressure, over speed, and other conditions.
A light on the remote LED plate is called the Diagnostic LED.
The LED will turn on and off in a series of blinks if certain
problems are detected in your Home Standby Generator. The
blink pattern is repeated with a brief pause between each
series. The number of blinks in the series indicates the
detected fault, as listed on the mounting plate and as follows:
