Basler Electric DGC-2020 - Manual (Page 132)

Not being able to stop the engine without removing ECU power causes two problems. The first problem is
that the only way to stop the engine is to turn the ECU off and wait for the engine speed to decrease
below 60 rpm before powering the ECU back on. Otherwise, the engine will take off running. The second
problem is that while the ECU is off, you can no longer meter and update coolant level, coolant
temperature alarm/pre-alarm, and crank control.
The DGC-2020 Solution
The DGC-2020 resolves ECU limitations by using four timers:
•
Engine Shutdown. G The time in seconds to stay disconnected from the ECU when going from
running to shutdown before starting the first pulse. This timer should allow enough time for the
engine to slow down so that when the DGC-2020 pulses, the ECU will not start the engine.
•
Pulse Cycle Time. H The time in minutes that the controller waits before pulsing.
•
Settling Time. I The time in tenths of seconds to gather data after connecting to the ECU during
the pulsing state. This allows all the metered values to be sent and ramp as designated by the
J1939 protocol. ECU values initially sent are low and the ECU takes time to average out its own
data values.
•
Response Timeout. J The time in seconds to attempt communication with the ECU when the DGC-
2020 is in the pulsing state or connecting state.

ECU Setup
The DGC-2020 can be configured for Standard, Volvo Penta, MTU MDEC, MTU ADEC, MTU
ECU7/ECU8, GM/Doosan, Cummins, MTU Smart Connect, Scania, or John Deere
A . When the Generator
Parameter Transmit B setting is enabled, the DGC-2020 broadcasts generator metered parameters over
CANBus as listed in Table 4-5. The Generator Parameter Transmit setting is not used when ECU Type is
set for MTU MDEC, MTU ECU7/ECU8, or MTU Smart Connect.
