Did you call savaria? 800-265-5416. I have this number saved in my phone for the old concord stuff. Not 100% sure it's been years since I called it but I think the ladies name I talked to there was Carrie. She was very good on them 8000 controllers. Hopefully they could at least email you schematics or a manual
I have all the prints, but I can't figure out what turns the cabin light off when the elevator is idle. I think it must be on one of the cards, but I don't have a clue. Hints anyone?
