The control device can be activated by means of opening and closing signals, but it ensures an independent control of the opening and closing movements of the door. With an opening signal present, during the actuation of a door handle the door is opened for a predetermined period of time. With a closing signal present, a closed door is locked, an open unused door is closed and locked, and an open used door is kept open for a predetermined period of time and then a closing operation is initiated. If the door is used during a closing operation this is at all events maintained for a predetermined period of time, then reversal occurs for a further period of time, subsequently a neutral holding of the door takes place for a further period of time, and then a new closing operation occurs. With a closing signal present, only a preadjustable number of reversing operations is possible, and subsequently the closing operation proceeds uninterruptably. The control device thus ensures that, after the closing signal has occurred, the door at all events closes within a specific period of time, and it is not possible to keep it open by a constant actuation of the reversing device. <IMAGE> |
