[Ultimaker Original+ after z-limit swich clicks, bed goes down about 150mm when doing auto home]

Just, assambled new Ultimaker Original+, but cannot set bed level to the right pisition. When doing auto home on ulticontroller or bed leveling via Cura, the bed goes to the nozzle, touches it, z limit switch clicks, and then bed is going down about 150mm and stays there.
