palletizer cell, 02:30, been down since the shift change. safety relay is a guardmaster msr127rp. friday day shift swapped the k2 contactor because the coil burnt, stores gave them a 100 c09 with the same coil voltage and they wired a1 a2 and the three poles like the old one.
now it wont reset. power led on, ch1 and ch2 leds on, k1 and k2 leds off, all e-stops pulled, both doors closed. press reset, nothing.
i metered 24.0v at a1 a2 and 24v on both channels, and s33 to s34 with the reset button held in reads open, which i dont get. day shift left a note saying jumper the feedback terminals to prove the relay is dead. im not doing that.
edit: forgot to say, no other faults on the panel today, photo of the relay and the new contactor attached. is it dead, any help would be appreciated?
One question. What's the wire number on S33, and where does the drawing say it goes before it gets to the button? Follow it on paper, not in the panel.
wire 412 off s33. drawing says 412 goes to k1 terminals 21 22, then 413 to k2 terminals 21 22, then 414 up to the reset button, then s34. on the old k2 the 21 22 was on a little block clipped to the front. new 100 c09 has nothing on the front. just coil and the three poles. day shift didnt move the block over, its in the scrap bin probably.
