Abstract
An elevator system includes a control for controlling an elevator into an idle state and/or for cancelling the idle state. The elevator system is configured to receive data from a control circuit external to the elevator system, and the control is arranged to form a control command for controlling the elevator into an idle state and/or for cancelling the idle state on the basis of data received from a control circuit external to the elevator system.
Claims4
An elevator system, comprising:
- an elevator control unit for controlling the movement of an elevator car in an elevator hoistway,
- wherein the elevator control unit is configured to receive data from a control circuit external to the elevator system, and the elevator control unit is arranged to start a new run sequence for cancelling an idle state of the elevator by transferring the elevator car from its current location during the idle state to that entrance at which it is assumed, on the basis of the information received from the control circuit external to the elevator system, that a passenger will arrive,
- wherein the elevator is controlled into an energy-saving mode during the idle state,
- wherein the elevator car is driven to a predefined point in the elevator hoistway during the idle state of the elevator, and
- wherein the electricity supply of one or more devices of the elevator system is arranged to be disconnected for the duration of the energy-saving mode.
