3.11 Exerciser Setup
The GSC400 can be set to automatically start the genset at regular intervals
while in the AUTO mode. This is controlled by the Exerciser Setup menu. The
Exerciser Enable should be set to Enabled if this feature is desired.
The GSC400 will display a message and sound the buzzer for a set amount of
time (Pre-Alarm Delay) to alert nearby personnel that the generator is about to
start. The engine/generator will run for a set period of time (Run Duration) and
then shut down.
The Start Date and Start Hour determine the date (0 to 31) and time when the
engine/generator will first start. After the first exerciser start, the
engine/generator will start up on regular intervals given by the Repeat Freq
which is measured in hours.
The exerciser feature depends on the GSC400 internal clock. Make sure the
clock is set to the proper time and date.
GSC400 internal clock information can remain “in memory” for approximately 2
weeks when no DC power is supplied to the controller. Two week memory
storage is available in a completely charged controller clock. DC power is
required to be supplied continually to the GSC400 for approximately 1 hour to
allow for a completely charged clock.
The remote start contacts (RSC) are ignored in an exerciser started run until
the GSC400 enters cool-down or AUTO. To prevent the engine from shutting
down set the cool-down time to a value other than 0. While in cool-down the
GSC400 will detect the RSC and will go back into the RUN mode without shutting
down.
