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.
Sliding door with at least one panel coupled with a belt-drive mechanism driven in turn by a motor by way of an electromagnetic clutch, whereby the panel is also connected to an auxiliary drive mechanism that is provided with energy by the panel as it slides into a closed position, that can move the panel when the clutch is deprived of current, with at least one programming switch, motion sensor, and limit switch for activating regular controls that move the panel automatically, and with additional electronic controls, characterized by a door-safety module (26) that is controlled in accordance with a program and has at least one motion sensor (27) and one limit switch (29) associated with it.
