Abstract:
PCT No. PCT/DE90/00793 Sec. 371 Date May 10, 1991 Sec. 102(e) Date May 10, 1991 PCT Filed Oct. 18, 1990 PCT Pub. No. WO91/09197 PCT Pub. Date Jun. 27, 1991.A sliding door with two for example panels coupled with a belt-drive mechanism driven in turn by a motor. The panels are also connected to an auxiliary drive mechanism that is provided with energy by the panel as it slides into a closed position and that can move the panel when the clutch is deprived of current. At least one programming switch, a motion sensor, and a limit switch activate regular controls that move the panel automatically. Self-monitoring additional electronic controls constitute a door-safety module. The object is to monitor the opening of the door in response to a signal from the motion sensor and to allow self-testing of the function of the auxiliary drive mechanism and ensure inherent reliability of the door-opening monitoring process. A door-safety module is controlled in accordance with a program and has at least one motion sensor and one limit switch associated with it.
