Operation
16 Owner’s Manual for 60 Hz Air-Cooled Generators
Setting the Exercise Timer
This generator is equipped with a configurable exercise
timer. Configuration can be performed directly at the control
panel or though the Mobile Link™ application. There are two
settings for the exercise timer:
Day/Time:
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 five or 12 minutes, depending on the model,
and then shuts down.
NOTE:
The exercise timer does not automatically adjust for
Daylight Savings Time.
Exercise frequency:
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 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 in 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
illustrates the engine speed profile during a typical exercise
cycle for 22 kW generators.
Figure 3-9
shows the engine
speed profile for 16–20 kW generators. Smaller generators
(9–11 kW) exercise at a constant 3600rpm.
The exercise timer must be reset if the 7.5 amp fuse is
removed.

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.
