hi ag. it certainly sounds like you have a contact fault with the slow down cct. its always alot easier to sequence relays with another lift next to you. if you notice ux/dx not coming in and on the other controller it does, find when the timing tells you it should be in, then just try pushing in the relay at that time and see if the lift levels in.if it does it certainly looks like you have a brush or contact fault whether its those or a trailing wire fault. either way you need to get the sequence right and alot of times over here the tuners used to write in pencil on the side of the selector the divisions from the master floor.
