Abstract

Es wird eine Aufzuganlage mit einer in einem Aufzugschacht (10) mittels eines Antriebsmotors (14) verfahrbaren Aufzugkabine (12) beschrieben, wobei der Antriebsmotor (14) mit einer Sicherheitsschalter (24) eines Sicherheitsschaltkreises (22) bewertenden Steuerung (26) zusammengeschaltet ist. Die Steuerung (26) weist mindestens einen Mikrocontroller (28) auf, in dem der Sicherheitsschaltkreis (22) abgebildet ist. Der mindestens eine Mikrocontroller (28) ist dazu vorgesehen und geeignet, dass der Antriebsmotor (14) zur Durchführung einer Not-Befreiungsfahrt eingeschaltet wird, wenn der mindestens eine Mikrocontroller (28) feststellt, dass ein für die gegebene Situation und/oder Position der Aufzugkabine (12) unkritischer Sicherheitsschalter (24) offen ist.The invention relates to an elevator installation with an elevator car (12) which can be moved in an elevator shaft (10) by means of a drive motor (14), wherein the drive motor (14) is interconnected with a controller (26) evaluating a safety switch (24) of a safety circuit (22). The controller (26) has at least one microcontroller (28) in which the safety circuit (22) is shown. The at least one microcontroller (28) is provided and suitable for switching on the drive motor (14) for carrying out an emergency release drive if the at least one microcontroller (28) determines that one for the given situation and / or position of the elevator car (12) non-critical safety switch (24) is open.
