Setting The Exercise Timer - Generac 20 kW Synergy Guia De Instalacion

7.8 — Setting the Exercise Timer
This generator is equipped with a configurable exercise timer. The first of two settings specifies the Day/Time of the
exercise. Once set, the generator will start and exercise on the day of the week and at the time of day specified. During
the exercise period, the unit runs for approximately five minutes, and then shuts down. The second setting establishes
exercise frequency, and can be set to WEEKLY, BIWEEKLY (the default), or MONTHLY. If monthly is selected, the day
of the month must be entered. Transfer of loads to the generator does not occur during the exercise cycle unless utility
power is lost.
IF THE INSTALLER TESTS THE GENERATOR PRIOR TO INSTALLATION, PRESS ENTER ON THE CONTROL PAD
TO SKIP EXERCISE TIMER SETUP.
The exercise information and programming options is shown in Table 7-1.
Figure 7-3 illustrates the engine speed profile during a typical low speed exercise cycle. While providing the necessary
periodic exercise, the lower RPM reduces fuel consumption, engine wear, and noise.
NOTE: The exercise feature operates only when the generator is in the AUTO mode and the Exercise Timer is
properly set. The current date/time must be reset every time the T1 circuit is shut down, the 12 volt battery is
disconnected, the 7.5 amp fuse is removed, and/or the battery charger is disconnected (control pad has no
power and LCD screen is blank).
