We are working on a 80's vintage solid state Westinghouse ERL controller which works normally when leveling into the floor. However if it needs to relevel due to load conditions or whatever it picks up 1 or 2 plus 6,6A, but will not pick-up 6P, which is the Brake. The print we have even shows that 6 and 6P are mechanically interlocked which is not the case on our controller. It has to have both to run. Obviously not the right prints. It's the same case in both directions.
