The electronic controller of each engine must be programmed with the correct engine number. The CCM will identify components by the engine number. The electronic controller is programmed to Engine Number 1 at the factory. Installations with one generator set per CCM will not need to change the engine number. Refer to the Operation and Maintenance Manual, "Data Link Guidelines" for more information on programmable engine modules. To change the engine number of the electronic controller, follow these steps: EMCP II Applications
Refer to the Systems Operation, "Engine Setpoints - OP5" of the appropriate EMCP II or EMCP II+ Service Manual. Follow the procedure for adjusting setpoints. The setpoint number is P22 - GSC Engine Number. The default value is 1, which corresponds to Engine Number 1.
Follow the procedure in the EMCP II manual to change the value of P22 - GSC to the desired value. The range of possible values are 1 through 8, which correspond to the engine number. Each unit that is connected on the same data link must have a unique number (MID).
