Generac Power Systems H-100 Internal Exercise Function, Quiettest Setup Using Genlink

INTERNAL EXERCISE FUNCTION

Generators best maintain their readiness by being exercised once per week. This prevents the machine from stagnating and provides an opportunity to dis- cover any maintenance items that may need service before the unit is actually needed for emergency power. In the past, the generator had to be exercised manually or an external exerciser was attached to the generator or transfer switch to activate the remote start once per week for a period of time long enough for the generator to warm up. With the advent of QT series of generators, that function was moved into the generator controller. This allows the QT series generator to have the QuietTest® mode of exercise as one of its key features. Normal mode exercise can be selected instead which can also exercise a Generac Commercial Transfer Switch (HTS) if desired. These features are all standard in the PowerManager® H- 100 controller, but require setup by the installer or end user. The internal exercise can be set up using GenLink or by using the front panel displays. This section describes the procedures needed to perform this setup.

The QuietTest® mode and Normal mode of exercise run the generator for approximately 20 minutes starting at a preset day and time once per week when the key switch is in the AUTO position and internal exercise is enabled. If the Normal exercise is used with the option to exercise an HTS selected, the exercise duration may vary based on the HTS set- tings. QuietTest® cannot exercise the HTS since the lower generator frequency and voltage used to reduce noise levels is incompatible with the standard system loads.

If the generator is needed for emergency power while exercise is running, exercise will be terminated auto- matically and the system will change to providing emergency power.

NOTE:

If “transfer on exercise” is selected with an HTS that is not a “Closed Transition Transfer Switch”, there will be a momentary (possibly several sec- onds) interruption in power to the load when switching from Utility to Emergency power and when switching back. For this reason, “transfer on exercise” is normally not selected.

QUIETTEST® SETUP USING GENLINK

Connect to the H-100 control panel. Using the “Configuration” pull down, select “Exercise Configuration” to display the Exercise Configuration screen.

Click on ”Select Exercise” to enable internal exercise and allow the changing of the other exercise param- eters.
