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.
DROOPOVERRIDE When the droop override logic element is true, the speed
and voltage trim functions are disabled. The machine
operates in speed droop and voltage droop to accomplish
kW and kvar sharing. This is useful when it is desired to
operate a system in droop rather than isochronous load
sharing.
DPFMANREGEN Diesel Particulate Filter Regeneration is forced manually
when the Set input is true.
DPFREGENINHIBIT Diesel Particulate Filter Regeneration is inhibited when the
Set input is true.
