COM2: MDEC MTU communication
The MDEC Engine Management System controls and monitors all the functions of MTU 2000 and 4000
Series genset engines. This system includes an Engine Control Unit (ECU), an Engine Monitoring Unit (EMU),
a Local Operating Panel (LOP) and engine wiring and sensors.
It incorporates a self-diagnosis system, complemented by a load profile recorder which stores the “service-
life data” of the engine in much the same way as a flight recorder.
MDEC also serves as the interface between the engine electronics and the overall generator including
gearbox, coupling and alternator.
Note: Selecting MTU MDEC communication prevents you from using extension remote I/O modules.
1/ MDEC configuration
To correctly communicate with GENSYS 2.0, MDEC internal variables have to be configured. The MDEC
should be configured as follows to activate the CAN communication:
200 set to 450.
201.01 set to 32.
201.05 set to 201.
For more information on MDEC configuration contact your MTU dealer.
2/ GENSYS 2.0 configuration
To activate the MTU CAN connection enter “Configuration/Engine/J1939-MTU” menu, and select:
Manufacturer : MTU
ECU type: MDEC.
Download the custom language. MDEC has labels and codes or numbers which correspond to the MDEC
variables:
Z090210_2_vxxx.txt corresponds to the English version.
Z090210_3_vxxx.txt corresponds to the French version.
Note: vxxx is the corresponding software version of your GENSYS 2.0.
