Abstract
Present invention relates to an automatic door operator 10 and method of operating said automatic door operator 10. The automatic door operator 10 is arranged to operate the movable door member D1, said automatic door operator 10 comprising a drive unit 24 for moving the movable door member D1 between a closed position and an open position, a controller 32 configured to control said drive unit 24 and a sensor S1 operatively connected to said controller 32. The sensor is configured to monitor the operation of the movable door member D1 and transfer sensor data to said controller 32.
Claims17
An automatic door operator for an entrance system having at least one movable door member, whereby the automatic door operator is arranged to operate the movable door member, said automatic door operator comprising a drive unit for moving the movable door member between a closed position and an open position, a controller configured to control said drive unit and a sensor operatively connected to said controller, said sensor being configured to monitor the operation of the movable door member and transfer sensor data to said controller, whereby the controller is configured to:
- receive a lock detection command and in response to said lock detection command cause the drive unit to attempt to move the movable door member towards a position (P) disposed between the closed position and open position, wherein such attempt to move the door member is opposed by a lock in a locked status,
- determine a door member status indicating whether the movable door member is locked by the lock in the locked status based on sensor data obtained from the sensor during the attempt to move the movable door member to the position (P), and
- generate a door member status signal based on said door member status.
A method of operating an automatic door operator for an entrance system, the entrance system having at least one movable door member, whereby the automatic door operator is arranged to operate the movable door member, said automatic door operator comprising a drive unit for moving the movable door member between a closed position and an open position, a controller configured to control said drive unit, a lock, and a sensor operatively connected to said controller, said sensor being configured to monitor the operation of the movable door member and transfer sensor data to said controller,
- wherein the method comprises:
- receiving a lock detection command;
- in response to the lock detection command causing the drive unit to attempt to move the movable door member to a position (P) disposed between the closed position and open position, wherein such attempt to move the door member is opposed by the lock in a locked status;
- determining a door member status indicating whether the movable door memberis locked by the lock in the locked status based on sensor data obtained from the sensor during the attempt to move the movable door member to the position (P);
- and
- generating a door member status signal based on said door member status.
