<p>The system (1) has an electrical power source (54) and a solar module (56). A data processing unit provided in the system comprises an active state and a passive state, where electrical signal connection of a control unit (50) of a gate or door drive unit (52) e.g. motor, is disconnected in the passive state. An initiation or wake-up signal with a control signal received by a control signal unit is supplied over an output signal unit of the control unit in the active state. An independent claim is also included for a gate or door closing system for a swivel gate or rolling shutter.</p> |
