If you look at the print, the up directional limit feeds UXA but level up comes in to pick U1, U2 even with UXA de-energized ( Page 3 of the print I’m looking at.) Seems like the car is leveling up but LU never drops. If you can’t catch it in the act with a meter in hand, the optical leveling card might be a good guess. Then again, if it has NEVER kept leveling up through another floor, maybe there is something wrong with the top floor plate. Could the selector carriage stick or bind on level up but the car keep moving?
