Hot Runner Temperature Controller alarm display-- shorted T/C

Hot Runner Temperature Controller alarm display-- shorted T/C


Possible reasons:

    The thermocouple is broken, the wire core touches the short circuit, the wiring at the connector touches the short circuit, and the connecting wire is melted and the wire core touches the short circuit. 


Diagnosis method:

1) Do the multimeter test the resistance of the corresponding pin or hole of the mold connector.

2) Remove the mold connector and check the wire end wiring, and directly measure the thermocouple resistance

3) The multimeter measures the two ends of the connecting cable to detect whether the inner wire is melted and shorted.

4) Remove the mold plate to check if the wire is pressed, the wire is broken and shorted
