ABSTRACT:
An electromechanically operated door having a control and regulation system for the door, the door for being driven by an electric motor, the movement of the door being controlled by sensors. The control and regulation system is equipped with a microprocessor control. In addition to the normal path of data to the microprocessor control, a dual redundancy is achieved, in that there is a safety monitoring system which receives the same safety-related information as the microprocessor control. This safety monitoring system, for its part, is capable of detecting a fault, i.e. if the microprocessor control system has not shut off the door, the door is shut off by the safety monitoring system, which for its part reports any faults which occur in the system to a fault detection unit, and here again, by means of a redundant shutdown unit, brings the connected motor and thus the door to an immediate stop. In addition to the automatic verification of the safety-related functions, manual verification of the safety functions is also possible. Also contemplated is a control and regulation system, having the above features, for a door.
