Hi all, company took on a job with a Kone KCM831 Hydro, 2001. Building lost power and car never came back on. I have my safeties, doors, Thermals and overloads, my 24v and 5v feeds to car and hoistway. I cant run on inspection, E1 shows a 0041 Emergency Brake fault, which makes no sense to me since its a hydro with an old Allen Bradley soft start. I also dont have the "shaft communcation ok" LED.

Any help would be greatly appreciated, I have prints but no real manuals or guides. I have a fault list but I am not even 100 percent sure its for this. I went though the car top board with a few safeties and door inputs. I havent gone through the COP to see what the condition of that board is. I havent found the LED on the prints for Shaft Communication to figure out what feeds it, is there a serial connection to a board in the shaft maybe?
