Section 3: Operation

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
programming options for all Home Standby generators.
