Used E-Stop, reset, removed part from chuck then shut machine down. Powered it back up the next morning and now have a 106 Alarm-A. I checked the breakers in the cabinet, nothing is tripped, so I fiddled with the e-stop button and reset a couple of times until it reset, but now the chuck wasn't working. The hydraulic pump was running and I could see the pedal switch working in the data. I shut it down and restarted, alarm was back but reset, chuck still wasn't working so I turned up the chuck pressure and heard it activate then the alarm set again.

Where do I look from here? I don't have a wiring diagram. I bypassed the e-stop button to rule that out, are there other relays on that circuit that may be faulty?

Thank you - Matt
