The invention concerns a device in electrically operated sliding doors and the like to control the pattern of movement of the door (1). The device comprises an electrically operated driving motor (15) to open and close the door (1), and an electronic control unit (18) connected to the driving motor (15). To said unit is connected a switch (20) in order to emit a signal, should the motor (15) be overloaded during the door closing movement, as also a means (21) for detecting the presence of any obstacles in the path of movement of the closing door (1), and a switch to sense the position of the door (1) as the latter reaches an end phase of its closing movement. As the door (1) reaches this position, the switch (23) is arranged to emit a signal to the electronic control unit (18), which is arranged to measure the time as from this very moment and to interrupt the closing movement, should it not have received a stop signal from the switch (20) and/or the sensing means (21) within a prescribed period of time. |
