I’m hoping someone here might be able to help me out. I was working on a Dover Relay Logic Hydro today. It has two tanks/pumps/pump motors. The car was shutdown, and I was able to trace the issue down to a bad overload relay on the MS1 contactor without prints. I replaced it with a spare and had car back up and running. I noticed that both pump motors continued running while at the bottom floor, nonstop. I waited atleast ten minutes and the motors were still running so I left the car shutdown. I spoke to the new route mechanic who says he’s always seen them both running constantly.

Is anyone able to provide me any print remotely close to this so I can see what feeds my motor contactor coils? Much appreciated if you can.

Controller Model: E-40761
Serial #: CW-16343
Volts: 460
