3-stop hydro faulting out on a 1027. Door zone monitoring error.
Comes up as “selector” in IMS.
I have replaced DZ1, and DZ2 relays. Made sure all the relays are making connection because it’s easy to not have them seated correctly, stupid design. I have checked for missing magnets and or debris in the selector, selector tape is clean. I have the prints and I have replaced additional relays that affect this circuit as well to play it safe. Unit will run for about 15 min and faults out. I hope im going down the correct rabbit hole as I’ve heard horror stories of tac20’s throwing incorrect faults. Im a bit lost on this one. It’s been down for almost a week and really seeking some guidance.
Any information would be helpful, thank you
