A natural gas booster station adopts HGM9310CAN genset controller and two AIN24 analog input module with Perkins 800KW gas turbine in Yulin, Shanxi.
Fault: customer said genset cylinder water temperature, A and B side main mixture gas temperature did not display(sometimes they displayed when stop).
After inspection finding that the positive pole and negative pole of charger power supply connect to controller directly, it disturbs signal when the charger works.
The corresponding solution is clearly in mind after finding problem: the positive pole and negative pole of charger connect to the positive pole and negative pole of battery directly. Then genset temperature signal, genset crank, stop operation temperature display are normal in the field.
