Engine Control Parameter Transmit
When the Engine Parameter Transmit setting is enabled, the DGC-2020HD broadcasts engine metered
parameters over CAN. When the Engine Parameter Transmit setting is disabled, transmission of J1939
commands from the DGC-2020HD to the engine are disabled, but commands from the engine to the
DGC-2020HD are allowed.
ECU Contact Control - Output Select
Select whether the RUN output relay or the PRE (Prestart) output relay closes to give the ECU its
“energize to run” signal. In some implementations, this relay may actually be providing ECU power.
ECU Contact Control - Pulsing Enable
Select if the ECU is not to be on line at all times. Often ECUs are allowed to go “off line” to conserve
battery drain when the engine is not running. The DGC-2020HD will “pulse” it periodically to force it to be
active to allow the DGC-2020HD to read data such as coolant temperature and coolant level. This is
required if the DGC-2020HD is to report low coolant temperature conditions (which may indicate a failure
of a block heater), or low coolant level conditions (if a leak occurs while the machine is not running).
Pulsing is also used to check the integrity of CAN communications when the machine is not running.
ECU Related Time Values - Engine Shut Down
Set this parameter for a value longer than the duration required to stop the engine after being shut down.
The ECU is pulsed after this time expires. If the time is too short, the pulse may occur while the engine is
still turning which could cause a brief re-start and possibly damage the flywheel and starter system.
ECU Related Time Values - Pulse Cycle Time
Set this parameter for the desired time between ECU pulse cycles.
