Internal Exercise Function; Quiettest ® Setup Using Genlink - Generac Power Systems H-100 Technical Manual

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.
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.
