Hello, this is the first time i have asked a question in this forum. I took over maintaining a duplex of resolve 20 kone controllers with the bar reader. One of the units comes into the floor kind of strange. On these controllers I beleive the relevel signals (61u 61n) are generated in the drv board from channels A,B from the bar reader. On car2 the 61u 61n signals come in backwards to the way they do on car 1. If car 2 doesn't stop level and has to relevel the controller starts and stops the relevel process because the signals seem contrary to the direction it is trying to relevel to. It will start/stop four or five times then take itself out of service and wait for another call in the system to answer. I think a new setup drive is required but to do that you have to start the car slightly below the bottom landing with the 61n signal off but these ones are backwards. Not sure if it will start the set up drive. To do a new setup drive you have to clear the old one. I may end up with a car that won't run. Any thoughts?
