- the energy storage cell takes over the supply of the moving system part electrical energy while the door leaf is in motion and thus the Coupling loop is broken.
- the path is closed Supply of the movable system part with electrical energy Sensors for door area monitoring via this path and thus loads the Energy storage cell not while it is being charged at the same time.
- the supply of the sensors for the door area monitoring is again from the Energy storage cell taken over.
- a further development of the device according to the invention is characterized in that that a device for monitoring the state of charge of the energy storage cell Movable system part is provided, the insufficient charge of the Energy storage cell a movement of the door leaf from the position in which the path to Supply of the movable system part with electrical energy is closed, prevented. This ensures that the door leaf only moves occurs when the moving system part has sufficient operating energy.
- the device for monitoring the State of charge of the energy storage cell via a device for measuring the Charging capacity of the energy storage cell. This enables a decrease in the Diagnosing the performance of the memory cell towards the end of its lifespan and ensure timely exchange.
- the system parts can expediently be supplied with electricity from the general electricity network Energy are supplied, with voltage converters being interposed if necessary are.
- the mains voltage can already be external to that for electronic devices necessary low voltage can be reduced.
- the fixed system part has a Data interface, in particular a serial interface, for connecting a Computer on.
