Data Log
Trigger A data log is triggered when the Trigger input is pulsed true.
DPF Manual
Regeneration Diesel Particulate Filter Regeneration is forced manually when
the Set input is true.
DPF
Regeneration
Inhibit Diesel Particulate Filter Regeneration is inhibited when the Set
input is true.
Droop Override 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.
Emergency
Stop When the Set input is true, an Emergency Shutdown alarm is
annunciated and the Emergency Stop LED on the RDP-110 is
illuminated.
Engine Run The Start input starts the generator. No load is applied. The
breaker remains open. The Stop input stops the generator. The
DGC-2020HD only responds to this logic element when in AUTO
mode.
EPS Supplying
Load When true, the Set input forces a supplying load indication. This
is useful when it is necessary for the supplying load indication to
be true during test runs, but the system load is not enough to
light the supplying load indication.
A supplying load indication is true when the supplying load logic
element is true and the generator is stable (voltage and
frequency are within programmed limits). This is OR’ed with the
traditional supplying load criteria that supplying load is true when
the generator current is above a percentage of CT primary
current (typically 3% minimum).
When the supplying load indication has been driven from logic or
from generator current levels, the DGC-2020HD will go through
a cool down cycle when it is in AUTO mode and the ATS contact
has been removed.
External Start
Delay If the Set input is true while the DGC-2020HD is in the Pre Start
state, the DGC-2020HD will remain in the Pre Start state until
the Set input is false.
