How can I Bypass External Hold Temorarily

The external hold circuit is normally closed. So if the external hold circuit is open you can put a jumper in the circuit. I would need to know what controller you have to tell you where to start looking.

Also are you sure it's an external hold and not a hold because the PLC is not on line or a welder is not on line?

You can edit in LAD Editor to coil "40067" False is not holding State.
