Want to run a job today and the door safety switch started acting up. It does this once and a while and I just do a soft reset and proceed. Machine was running ok for an hour of two setting up tools before this happened. Then it threw a 53+ error and I had to restart. I tried adjusting the door key stop as that has helped before, restarted then it wouldn't get past I01 initialization by pressing ON and CLEAR buttons. I had a spare new euchner switch not exact pn but the same type red contractors inside. Swapped out the contractors no change. I checked all the control relay contactors and all seem ok with no high resistance.
I did notice before changing the red contractors and after that the switch keep magnet was on whether the door was closed or not. Pin 3 on the euchner barrier was hot, 24vdc. Maybe that little circuit board that controls the magnet is bad?
Anyone have a similar problem on their DMU50V?
Ok I put the machine into diagnostics mode (rubber band on the 7S2 switch and it initialized! I moved the axis around some and then was able to restart normally. Ive been running a warmup program for the past 10 min.
