    High Oil temperatuer reading on Injection molding BOY

    We have a BOY injection molding machine. Yesterday I noticed a high temperature reading on oil about ~80 degree Celsius which I thought was a false reading because we shut down the machine two days ago and nothing should be hot. I check this morning the problem still persist. Do any one have any idea? is the thermosensor broken? Thank you very much for all the help and information you can provide! (I attach the screen shot of the machine window)

    If the pump was left running or the start up clock turned on the pump with the cooling water off, The it may be hot. Can you reach tank and put a hand on it to see if it’s really hot? It may be a bad sensor but that’s rare for the oil temperature unit.
