To anyone who has had this problem. While changing the small watch type battery in the car station on the clc board with the power on. Once the battery was changed the elevator would not respond to any type of calls or run on top of car inspection. When the elevator is sitting on automatic at floor level I have all the relays energized except "in" and the question is how do I get "in" to energize and what does "in" stand for? The prints on this site do not seem to match the unit which makes it even more difficult. Do I need the "programming tool" in order to correct this problem or is there something that I am completely missing? Any suggestions would be greatly appreciated.
