I changed out air compressor and Tech changed out arm bearing and gearbox. 04 circuit prot tripped is showing. Checked all breakers checked all manual operations working. Is there a reset for codes?
If your machine has an FX2N or FX3U, please check PLC inputs X17, or anything between X70-X77. If any of those are still "on", you have a circuit protector or current relay tripped.
