Name Description Symbol
Setting Group There is a direct correlation between each logic input and the
setting group that will be selected. That is, asserting input D0
selects SG0 (Setting Group 0) and asserting input D1 selects
SG1 (Setting Group 1), etc. The active setting group latches-in
after the input is read so they can be pulsed. It is not necessary
that the input be maintained. If one or more inputs are asserted
at the same time, the numerically higher setting group will be
activated. A pulse must be present for approximately one
second for the setting group change to occur.
Single-Phase
Override When the Set input is true, the DGC-2020HD switches to single-
phase sensing configuration and uses the Single Phase
Override Sensing setting (A-B or A-C).
Speed Lower This element lowers the speed setting of the DGC-2020HD by
up to 2 rpm per second. After the speed has not been lowered
for 30 seconds, the modified speed is saved to nonvolatile
memory.
Speed Raise This element raises the speed setting of the DGC-2020HD by up
to 2 rpm per second. After the speed has not been raised for 30
seconds, the modified speed is saved to nonvolatile memory.
Speed Trim
Inhibit When true, this element inhibits operation of the DGC-2020HD
speed trim PID controller. For example, speed trim is not desired
in multiple generator systems during start up synchronization
until the generators are stable.
Start Delay
Bypass This element allows the Pre Start state to be skipped based on
logic. For example, a start delay may not be necessary when the
engine is warm. This also allows an external device, such as an
ECU, to control the pre start interval.
Start Output This element is used to drive the start output relay from logic
when the Start Output Relay configuration is set to
“Programmable”. When the Start Output Relay configuration is
set to “Programmable”, the start relay will not close unless logic
is used to drive this element. When the Start Output Relay
configuration is set to “Predefined”, the start relay is closed
according to the predefined start functionality of the DGC-
2020HD. When the “Predefined” functionality is selected, the
relay will not respond to this element.
Stop kvar
Ramp When the Set input is true, any kvar ramping in progress will be
stopped at the current value. When the input is removed,
ramping will resume.
Stop kW Ramp When the Set input is true, any kW ramping in progress will be
stopped at the current value. When the input is removed,
ramping will resume.
Test Inhibit When this logic element is true, the generator exercise timer
cannot start the generator. If the TESTINHIBIT logic function is
false during an exercise period, or transitions from true to false
at any time during an exercise period, the DGC-2020HD will
start and run the generator for the duration of the exercise
period.
