  • control of the door member 110 between the open and closed positions is performed. During said control, the acquired positional difference is taken into account such that the respective positions of the automatic door operators lOa-b are adjusted. Hence, levelness between the leading edge 112 and the floor level 21 is consistently achieved.
  • adjusting the respective positions of the automatic door operators lOa-b in the travelling direction involves causing either one or both of the automatic door operators lOa-b to be driven in a vertical upwards or downwards direction, with respect to the floor level 21, for a distance determined by the positional difference. For instance, if it is determined that the positional difference between the two automatic door operators lOa-b is 10 cm, the goal is to make the automatic door operators lOa-b level. This may be done either by causing vertical movement of one of them 10 cm towards the other, or alternatively by causing vertical movement of one of them 9 cm towards the other, and 1 of the other towards the first.
  • 8/2 cm, 7/3 cm, 6/4 cm or any other suitable driving procedure relation may be realized, provided that the effect is an achieved levelness between the automatic door operators lOa-b. If levelness between said the automatic door operators lOa-b can be achieved, the leading edge 112 will accordingly be levelled with respect to the floor level 21 in the door member’s 110 closed position, hence ideally eliminating air flow leaks.
  • adjusting the respective positions of the automatic door operators lOa-b in the travelling direction involves causing the first and second automatic door operators lOa-b to drive the door member 110 until one of the lateral sides 115, 116 reaches its closed position. Subsequently, the adjusting involves causing either the first or second automatic door operator lOa-b whose associated lateral side 115, 116 has not yet reached the floor level 21 to be driven in the travelling direction for a distance determined by the acquired positional difference. In this embodiment, a corresponding opposite control procedure is realized for the opening movement.
  • This embodiment may involve driving the first and/or second automatic door operators lOa-b differentially with respect to a travelling distance, a travelling speed, or a combination thereof.
  • the adjusting of relative positions between the automatic door operators lOa-b may be caused any time during the normal operation in the operation mode.
  • the adjusting of relative positions is caused upon the door member 110 approaching the closed position and upon leaving the closed position.
  • Upon approaching or upon leaving may, for instance, correspond to 1 to 10 centimeters from triggering an output switch of the door status module 20 (transitioning from closed to non-closed state, or vice versa).
  • the effect is that the door member 110 is driven along the vertical structures of the entrance system 100, for instance the door frame 114, without causing wear and tear on said structures.
  • tilting of the door member 110 is caused such that the alignment thereof corresponds to the tilt of the floor level 21.
  • the calibration values are determined in the calibration mode of the entrance system 100, and the relative positional adjustment of the automatic door operators lOa-b, and thus the door member 110, is caused in the operation mode whenever a few centimeters (for instance less than approximately 5 cm) are left before the closing of the door member 110, or whenever the door has moved a few centimeters (for instance less than approximately 5 cm) away from the closing position during the opening procedure.
  • the last thing that happens before the door status module 20 outputs a closed state is thus a tilt of the door member 110 with respect to the floor level 21.
  • the first thing that happens after the door status module 20 no longer outputs a closed state is thus an “un-tilt” of the door member 110 with respect to the floor level 21.
