Hello to everyone,
I have a chiller mounted on a commercial building which has stopped functioning and gives a control motor error.This model has one single screw steples compressor and on his side it has mounted a control motor which controls the load of the compressor. I tested that control unit according tot the service manual and it is working ok.But the system says it is a control motor error, so i started to look on the electrical circuit of that unit and it inlucdes 2 optocouplers and 1 contactor.so i managed to resolve to work for the load down but when it is loading up the control motor is does not run, in the circuit it does not have 230 v to run that litle motor.
Can anybody help to solve this problem?
I can atache the service manual so you can look over the electrical wireng.
Need help SOS it is werry hot outside and the chiller does not work over a month so the management is realy pissed of.
Thanks Alex.
