Controller for an automatic drive of a door

摘要

A controller for an automatic drive of a door with rabbet casement, swing leaf or shash with an electric drive motor and an electronic control device is described. In order to obtain an optimum opening and closing speed and in order to optimise the operational safety for the user, the control device has a data processing unit which carries out a sequencing program in such a form that a multitasking system carries out the chronological sequence of the continuous test procedures, and continuous monitoring of the process hardware and of the external control elements is carried out.
