COOLDOWNREQ RUN Mode
If the unit is in RUN mode when the Cool Down Request is
received, the unit is forced to unload and open its breaker and then
go into a cooldown cycle. While in the cool down cycle, the unit will
display “COOLDOWN REQ” in addition to displaying the cooldown
timer. After the cooldown timer expires, the unit will remain running
in RUN mode. The Cool Down Request must be removed before
the breaker can be closed again; this element blocks breaker
closures.
If the Cool Down Request is removed during the cool down
process, the unit will remain running in RUN mode. Furthermore, if
a condition occurs that normally causes the unit to close its breaker
in RUN mode, the unit will close its breaker and reload.
AUTO Mode
If the unit is in AUTO mode and the Cool Down Request is
received, the unit is forced to unload and open its breaker and go
into a cooldown cycle. While in the cooldown cycle, the unit will
display “COOLDOWN REQ” in addition to displaying the cooldown
timer. After the cool down timer expires, the unit will remain running
in AUTO mode, unless there are no conditions that cause the unit
to run in AUTO mode, in which case it will shut down and remain in
AUTO mode. The Cool Down Request must be removed before the
breaker can be closed again; this element blocks breaker closures.
If the Cool Down Request is removed during the cool down process
and some condition that would normally cause the unit to run in
AUTO mode is true, the unit will remain running in AUTO mode.
Furthermore, if a condition occurs that normally causes the unit to
close its breaker, the unit will close its breaker and reload.
ENGINERUN The Start input starts the generator. No load is applied. The
breaker remains open. The Stop input stops the generator. The
DGC-2020 only responds to this logic element when in AUTO
mode.
EXTSTARTDEL If the Set input is TRUE while the DGC-2020 is in the Pre Start
state, the DGC-2020 will remain in the Pre Start state until the Set
input is FALSE.
