Abstract: A swing door operator for moving at least one door leaf between a first and a second position includes a motor and a mechanical drive unit connected to and capable of moving the at least one door leaf from the first position to the second position, and a braking circuit connected to the motor. The braking circuit includes a diode circuit arranged to apply a voltage drop to the motor. The motor is adapted to act as a generator and is configured to generate a voltage when the drive unit moves the at least one door leaf, and to brake a movement of the at least one door leaf when the voltage generated by the motor is larger than the voltage drop applied by the diode circuit. The diode circuit includes at least three diodes connected in series.

Abstract: An automatic door operator (30) for a swing door assembly (10) having a door leaf (14) rotationally supported by a door frame (12) is disclosed. The automatic door operator has a motor (34) for causing opening of the door leaf (14) with respect to the door frame (12), and a controller (31) being configured for performing different functions (60) of the automatic door operator. The controller (31) is configured to detect (42) a movement of the door leaf (14), not caused by the motor (34), identify (44) a predefined movement matching the detected movement, determine (46), among the different functions, a function (61-A, 61-B) being associated with the predefined movement, and perform (48) the determined function.

Abstract: A method (1000) for testing of a door operator (100), the door operator (100) being configured to via a mechanism (104) move at least one door leaf (200) between a first position and a second position. The door operator (100) includes a first drive unit (102) configured to optionally move the door leaf (200) into said first position and a control unit (103) connected to a sensor (105). The method includes the steps of initiating a simulated powerless mode, measuring operation of the door leaf by the sensor, and comparing measured values of movement with reference values.
