How to Synchronize CAT C18 Model Diesel Engine

Dear Members,

I have 3 no's of CAT C18 model Diesel generating sets(MUEI). Now I want to automatic synchronize each others. I have already identified for alternators biasing systems but I am unable to identify for Engine speed biasing system. I found the existing CATERPILLAR used 9X9857 speed governor but noted that "speed control not fitted when electronic load share required". Mentioned details as bellows:

Speed controller Wire no. ---------------(Module point no)

42, 43, 44, S-SPD, 0-SPD, 10 and 30----(1, 2, 3, S, D, +B, -B)

42(3), 43(2), 44(1) also connected with 1K, 10T speed adjust potentiometer. Do u know for electronic load sharing what is P/N or model no will be applicable? My question is how it will be shared the load automatically? Is there any alternative controller required? Please advice me details. I also checked that the S-SPD is connected with the Engine ADEM3 at pin no 66 (mentioned rated speed) but 0-SPD is not connected. Please advice me details. Thanks
