An entrance system comprising: a swing door having opposing first and second door leaf surfaces (12-1, 12-2) and being pivotally supported at a vertical door edge, also known as a secondary closing edge, by at least one hinge for allowing opening of the swing door from a closed position to an open position with the first door leaf surface being a leading surface and the second door leaf surface being a trailing surface during such opening, as well as for allowing closing of the swing door from the open position to the closed position; an automatic door operator comprising a motor capable of causing opening of the swing door in an automatic mode of the entrance system, characterized in that the entrance system also has a manual mode in which a human user may cause opening and closing of the swing door by manual force; and a control arrangement for controlling the automatic door operator, the control arrangement comprising a controller and a plurality of sensor functions (S1... Sn) for monitoring respective zones at the entrance system for presence of a person or object, wherein the sensor functions comprise: • a first sensor function for monitoring a first zone at the first door leaf surface and non-proximate to said vertical door edge, and • a second sensor function for monitoring a second zone (PDHA) at the first door leaf surface and proximate to said vertical door edge; and wherein the controller is configured to: when any of the first sensor function or second sensor function detects presence in the first zone or second zone (PDHA) in the automatic mode during an ongoing opening of the swing door, control the automatic door operator to stop opening of the swing door, and when the second sensor function detects presence in the second zone (PDHA) in the manual mode, control the automatic door operator to counteract an attempt by a human user to manually open the swing door. a swing door having opposing first and second door leaf surfaces (12-1, 12-2) and being pivotally supported at a vertical door edge, also known as a secondary closing edge, by at least one hinge for allowing opening of the swing door from a closed position to an open position with the first door leaf surface being a leading surface and the second door leaf surface being a trailing surface during such opening, as well as for allowing closing of the swing door from the open position to the closed position; an automatic door operator comprising a motor capable of causing opening of the swing door in an automatic mode of the entrance system, characterized in that the entrance system also has a manual mode in which a human user may cause opening and closing of the swing door by manual force; and a control arrangement for controlling the automatic door operator, the control arrangement comprising a controller and a plurality of sensor functions (S1...
