Setting the Exercise Timer
This generator set is equipped with a configurable exer-
cise timer. There are two settings for the exercise timer:
Day/Time: Generator set 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 auto-
matically adjust for Daylight Saving Time.
Exercise frequency: Exercise frequency can be set to
Weekly, Biweekly, or Monthly. If Monthly is selected, day
of the month must be selected from 1-28. Generator set
will exercise on that day each month. Transfer of loads to
the generator output does not occur during the exercise
cycle unless mains power is lost.
NOTE: The exercise feature will operate only when the
generator set 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 exercise information and programming
options for all home standby generator sets. Figure 3-7
illustrates the engine speed profile during a typical exercise
cycle.
