I recently got a call from a division I have not worked at in over a year, they have a mrc welding machine they wanted to fire up.
Nobody took my advice about keeping power to the machine and they shut it all down and off.
So I took a look, I am checking the deadman switch right now as we speak.
Normally, I make sure the safety doors are closed, and that all the sensors are green and nothing to it, throw it in teach turn on servos, and master job call and they are rolling..
I really like these old motoman machines, but when they go down, and people have no documentation at all, it sucks!
Does anyone have any tips or advice about troubleshooting? (I at this moment can not get the stations to reset?
no obvious errors to clear (am not sure I am looking in all the right places, I I went from NX, to XRC, to MRC ,,,(started in erc's, then went to IGM,s so).
(I am pulling out voltmeters and looking, at switches for continuity)
I also am thinking battery issues are gonna be part of this.
Also I just noticed the shock sensor even when the head is jostled its lit like its in place? (wondering if someone shorted around it?),,,this worries me.
Verified the dead man switch, appears good.
So on the the holding circuit?
