Put this one to bed. Apparently the route mechanic had a vane pile up on the MUS & MDS mags (mfs sw’s) a few weeks back. He remounted the MDS & MDS1 switches opposite of what they drive in the controller. MDS drives FSP MDS1 drives HSP. So in the down direction FSP flashed before HSP which initiated a 1SD slowdown prematurely dropping HS way early then leveling all the way into the target floor. Corrected that now onto the problem with stepping up.

A simpler one here. From the bottom floor up the elevator never saw the MUS & MUS1 at the 2nd floor which caused the elevator to get out of step. The MSU & MSU1 vane didn’t engage the MSU & MSU1 mfs switch enough. Adjusted & rts.
