DGC-2020ES
Description
This element is used to connect the breaker open and
close output signals from the DGC-2020ES to physical
output contacts to open and close the generator breaker,
and map breaker status feedback to a contact input. In
addition, contact inputs can be mapped to allow switches
to be implemented to manually initiate breaker open and
close requests.
Inputs
Status: This input allows a contact input to be mapped
that will provide breaker status feedback to the DGC-
2020ES. When the contact input is closed, the breaker is
indicated to be closed. When the contact input is open,
the breaker is indicated to be open.
Open: This input allows a contact input to be mapped that
can be used to initiate a manual breaker open request.
When this input is pulsed closed while the DGC-2020ES
is in RUN or AUTO mode, the breaker will open.
Close: This input allows a contact input to be mapped
that can be used to initiate a manual breaker close
request. When this input is pulsed and the DGC-2020ES
is in AUTO or RUN mode, and the generator is stable, a
close request will be initiated. If bus is dead, the breaker
will close; if the bus is not dead the generator breaker will
not be closed.
Outputs
The outputs must be mapped to the contact outputs of
the DGC-2020ES that will be used to drive the breaker.
Open: This output is pulsed true (closes the output
contact it is mapped to) when the DGC-2020ES is
providing a signal to the breaker to open. It will be a pulse
if the Breaker Output Contact Type is set to Pulse on the
Breaker Hardware screen under Breaker Management in
the Settings Explorer, and the length is determined by the
Open Pulse Time. It will be a constant output if the
Generator Breaker Hardware Contact Type is set to
continuous. Note the pulse time must be set long enough
for the breaker to actually open before the pulse is
removed.
Close: This output is pulsed true (closes the output
contact it is mapped to) when the DGC-2020ES is
providing a signal to the breaker to close. It will be a
pulse if the Breaker Output Contact Type is set to Pulse
on the Breaker Hardware screen under Breaker
Management in the Settings Explorer, and the length is
determined by the Open Pulse Time. It will be a constant
output if the Generator Breaker Hardware Contact Type
is set to continuous. Note the pulse time must be set long
enough for the breaker to actually open before the pulse
is removed.
When this element is true, the DGC-2020ES sends an
idle request to the ECU on J1939 engines that are
equipped to receive such a request. The request consists
of an enable bit command and an idle RPM setting. At
this time, only Volvo and Cummins are implemented.
ECUs that accept the idle RPM setting set the engine to
the requested RPM. ECUs that accept only the enable bit
command, set the engine to their internal idle speed
setting, ignoring the requested idle RPM from the DGC-
2020ES.
