Caterpillar Ecm Speed Governing

06/22/2011 9:35 AM

Hi all

I am trying to synchronize three C18 caterpillar generators with emcp 3.1 control modules by the DKG-707 multi generator set paralleling unit .I choose this paralleling unit because I have used it to synchronize Cummins generators and I do have the controller now. But I haven't synchronize the caterpillar generator set before and I am not clear of the following points

1. Does the ADEM III ECM for C18 engine have an option for adjusting the speed from the speed up/down relay output of the DKG-707 control module?

This is the paragraph from the controller manual about the digital relay output.

"9.18 speed up/down relay output

The DkG-707 is able to control motorized potentiometers through up/down output functions. In order to use up/down functions, corresponding digital output function P_8x0 parameters should be set properly.

If speed up/down outputs are enabled, the master unit will operate in order to adjust itself to the nominal speed defined in program parameter P_A38.

If speed-up or speed-down functions are assigned to digital outputs, then the unit will start to generate speed up/down pulses to control the external speed potentiometer. Thus the analog GOV control output is no more valid.

The minimum pulse width is set through program parameter 9P_A33), the minimum delay between two successive pulses is set through program parameter (P_A34), and the maximum speed pulse width is set though program parameter (P_A39)"

2. If it is possible do we need to have a password or do we need a caterpillar service tool to enable this function on the ECM.

3. I know that the ECM has a PWM speed adjustment input .do we need the caterpillar service tool to enable this function.

CURRENTLY I DON'T HAVE THE GENSET MANUAL BUT I WILL HAVE IT LATTER ON .THAT IS I WHY AM ASKING SOME OF THE QUESTION.

PLEASE SUGGEST ME ANY LINKS WHERE I CAN FIND THE ECM SCHEMATIC FOR THE C18 GENERATOR ENGINE

Thanks
