Dear colleagues, I have a problem with EFW. unfortunately I can't get it up and running. when switched on, it moves to a position between two positions. it throws an error during calibration. calibration failed. I tried to tighten and loosen the center screw. The wheel everything seems to be working properly, it just can't be calibrated and ended up in the wrong position. powered directly from about air by original cable. Tested in all possible positions. Carusel is rotating freely, but it always stop betwen two positions. Thank you very much for any advice.
