GENBRK

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.

IDLEREQUEST

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.

LAMPTEST

The lamp test will be performed when this element is true.
The lamp test can also be accomplished by simultaneously
pressing the Up and Down buttons on the front panel of the
DGC-2020ES.
