The the best of my knowledge, A kone with wittur AMD/SGV doors will, when power is first applied to the main KCM controller, door will open slowly if at a landing (otherwise close), then close slowly if open. This is done to ensure no jumpers are on the door locks, since the door is initially blind to its location. Once at the closed end, both KONE and Wittur SUPRA/MIDI versions will encounter a reference switch (REFSW on the door board of both versions). Once REFSW is lit, door should return to normal speed.
