EMR 2
System Functions
4 System Functions
The EMR 2 makes a broad range of functions available and these can be activated by the application-
dependent configuration and the allocation of the inputs and outputs. It makes possible signal exchange
between the engine (via the engine plug) and the EMR 2, as well as between the vehicle (via the vehicle
plug) and the EMR 2. The signals can be transmitted as analog, digital, impulse modulated (PWM signals)
and as CAN-Bus messages.
Which functions are used, depends on the application conditions of the engine. Correspondingly, there are
different variations of the functions and the pin assignments of the plugs.
The functions of the EMR 2 refer to the speed control, quantity limitations (fuel injection), monitoring,
vehicle and apparatus functions and communication and diagnostic interfaces.
The EMR 2 offer a basic equipment on which all the optional variations can be structured.
Because of the numerous possibilities of combinations, DEUTZ has defined function ranges. These can be
crossed off in the DEUTZ pocket handbook. The switching diagram for each function range should also be
noted especially for the wiring required on the customers side.
