Setting the Exercise Timer
This generator is equipped with a configurable exercise
timer. There are two settings for the exercise timer.
Day/Time: Once set, the generator will start and exercise
at a predetermined day and time. During this exercise
period, the unit runs for approximately 5 minutes and
then shuts down.
Exercise frequency (how often the exercise will take
place): Exercise frequency can be set to Weekly,
Biweekly or Monthly. If Monthly is selected, the day of the
month must be selected from 1–28. The generator will
exercise for 5 minutes on that day each month. Transfer
of loads to the generator output does not occur during the
exercise cycle unless utility power is lost.
NOTE: If the installer tests the generator prior to
installation, press the “enter” button to skip setting up the
exercise timer.
NOTE: The exercise feature will operate only when the
generator is placed in the AUTO mode and will not work
unless this procedure is performed. The current date/time
will need to be reset every time the 12 volt battery is
disconnected and then reconnected, and/or when the
fuse is removed.
Table 3-1 details the exercise information and
programming options for all Home Standby generators.
Figure 3-8 shows the engine speed profile during a
typical low speed exercise cycle. While providing the
necessary periodic exercise operation, the lower rpm
also reduces fuel consumption, engine wear and noise.

Battery Charger
NOTE: The battery charger is integrated into the control
module in all models.
The battery charger operates as a smart charger that
verifies:
• output is continually optimized to promote
maximum battery life.
• charging levels are safe.
NOTE: A warning is displayed on the LCD when the
battery needs service.
Manual Transfer Operation
Prior to automatic operation, manually exercise the
transfer switch to verify that there is no interference with
proper operation of the mechanism. Manual operation of
the transfer switch is required if electronic operation
should fail.
Transfer to Generator Power Source
1. Verify generator is OFF.
2. Set the main line circuit breaker (MLCB) (generator
disconnect) to OFF (OPEN).
3. Turn off the utility power supply to the transfer
switch using the means provided (such as a main
line utility breaker).
4. Use the manual transfer handle (A in Figure 3-9)
inside the transfer switch to move the main
contacts to STANDBY (loads connected to the
standby power source).
5. Press the control panel MANUAL button to crank
and start the engine.
6. Allow the engine to stabilize and warm up for a few
minutes.
7. Set the MLCB (generator disconnect) to ON
(CLOSED). The standby power source now
powers the loads.

Disconnect transfer switch from all power sources
prior to manual transfer. Failure to do so will result
in death or serious injury, and equipment damage.
