DGC-500 Installation 5-9
Volvo Penta EDC Applications
Engines equipped with Volvo Penta EDC controllers can receive engine control commands (such as start and
stop) from the DGC-500 through the SAE J1939 communication interface. To invoke this feature, the EDC
must receive a J1939 message containing engine control information within one second of waking (exiting
sleep mode). If the EDC does not receive an engine control message within the prescribed time, it will enter
the stand-alone mode and ignore any J1939 control messages. If this occurs, the EDC must be forced back
into sleep mode by pressing the auxiliary stop pushbutton on the engine or by momentarily disconnecting EDC
power.
The interconnection diagrams of Figures 5-10, 5-11, and 5-12 illustrate the DGC-500 and EDC connections
that allow the DGC-500 to awaken the EDC and start the engine, or simply acquire engine status information.
Wake-up of the EDC is initiated by using the DGC-500 Fuel output contacts to apply battery power to the
EDC. To stop the engine, the DGC-500 issues a sleep command through the J1939 interface to the EDC and
opens the Fuel output contacts. This causes the EDC to stop the engine and enter the sleep mode.
In order for the DGC-500 to communicate with the EDC, two DGC-500 settings must be changed from their
default values.
C
The J1939 address of the DGC-500 must be set at 17
C The engine start/stop configuration setting must be set for Volvo Penta
Both settings are configured on the System Settings screen of BESTCOMS. Section 4, BESTCOMS Software
has information about adjusting DGC-500 settings through BESTCOMS.
