3.9 — Setting the Exercise Timer
This generator is equipped with a configurable exercise timer. There are two settings for the exercise timer. One is Day/Time. Once it is 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. The other is for the exercise frequency (how often the
exercise will take place). It can be set to WEEKLY, BIWEEKLY or MONTHLY. If monthly is chosen, the date of the month must be selected and
the generator will exercise on that day each month.Transfer of loads to the generator output does not occur during the exercise cycle unless util-
ity power is lost.
IF THE INSTALLER TESTS THE GENERATOR PRIOR TO INSTALLATION, PRESS THE "ENTER" BUTTON TO SKIP SETTING UP THE
EXERCISE TIMER.
Table 3-1 details the exercise information and programming options for all Home Standby generators. Figure 3-7 illustrates the engine speed pro-
file 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.
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
