The barrel temperature of the moulding machine seem to be out of control as the temperature kept rising . I had changed a new contactor but the problem remains. Then I changed the themocouple and the electronic temperature controller as well but the problem still was not solved. I could not figure out what went wrong as this had never happen before. Dear members can you give me some advice. Thank you.
Regards
What are you running and what is the setpoint temperature? Is this a reactive system which could be creating the exotherm?

Check for reversed thermocouples or plugs.
The material used is PC . I had replace a new set of controller ,T.C , contactor and also check that all electrical connection was properly done, The contactor should be in a cut off posistion when the barrel temp. has reach the set- temp. but it does not.
But yesterday the problem solved without any reason. I still don't know why ?
