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
for the period defined, on the day of the week and at the
time of day specified. During this exercise period, the unit
runs for approximately 5 or 12 minutes, depending on the
model, and then shuts down.
Exercise frequency (how often the exercise will take
place):
It 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 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 3-7 illustrates the engine speed profile during a
typical exercise cycle for 22 kW generators. Figure 3-8
shows the engine speed profile for 16-20 kW generators.
8-11 kW generators exercise at a constant 3600 rpm.
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
ensures:
• 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.
