U better check the mold open/close valve & coils.the coils resistance is 22 ohm.if coil is ok then coil voltage, it very 16 volt to 24 volt for differant kind of pressure. if voltage ok then check open/close pressure valve it might be jammed with dirt. change it or clean it.if valve, volt & coils r ok then u need to change PLC card.

Check fuse in attached photo.
Two years passed, you'd better replace the PLC.

there is no NEUTRAL output signal any of the 8 red cables on the right bottom side of PLC Card.

So Machine is not working because of this problem. Please inform me if there is any solution for this problem.

Do we have to change PLC card ?
