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 minutes and then shuts down.
NOTE: If Wi-Fi is enabled, the exercise timer will
automatically adjust for Daylight Saving 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: The exercise feature will operate only when
generator is in AUTO mode, and will not work unless this
procedure is performed. If Wi-Fi is NOT enabled, 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 3-10
illustrates the engine speed profile during a typical exercise
cycle.

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 maxi-
mum battery life.
•
charging levels are safe.
IMPORTANT NOTE: Contact an IASD if the controller
screen displays “CHARGER MISSING AC.”
NOTE: A warning is displayed on the LCD when the
battery needs service.
NOTE: Do not use external battery chargers.
