Miprom HS 3 stop

Car will not stop at the 2nd landing up or down. But will run fine otherwise with no faults. All LEDS are showing correct operation but high speed valves drop and pick back up. We have replaced sensors and have a new hydro level shifter board coming on Monday. Anyone have this problem before.

Usually a problem like this is due to the slow down or leveling magnets having the wrong polarity. At the 1st floor if all the magnets are north, the next floor should be south. The next one north etc; etc; White is south, black or a groove is north. If the polarity is wrong on a magnet the floor count goes off in the weeds, and the car doesn't slow down. also check the running clearance on the sensors. It should be near 3/8",
.

New board fixed the problem. Thanks
