METHOD AND DEVICE FOR CONTROLLING A VERTICAL OR HORIZONTALLY MOVING GATE WHILE SECURING THE GATE CLOSING PLANE AGAINST OBSTACLES

摘要

The invention relates to a method for controlling a gate by means of a motor drive along at least one straight guide device over a rectangular gate opening, wherein distance measuring detector beams are moved synchronously to create a forked detector beam probe system in front of and behind the gate closing plane, wherein the individual distance measuring detector beams create safety curtains configured in a particular manner on a gate inner side and a gate outer side separated by the door closing plane, and wherein detector output signals arising when an obstacles occur can be input to a simplified processor due to the synchronous pivoting of the distance-measuring detector beams.
