Abstract
At least one leaf of this door is equipped with a detection device comprising a mechanical detection device and a contactless sensor each capable of detecting a presence. The control circuit board comprises a control unit for movement of each leaf and a diagnostic unit, while means transfer, from the detection device in the direction of the diagnostic unit and the control unit, a first item of information representative of the activation state of the mechanical device, and a second item of information representative of the activation state of the contactless sensor. The diagnostic unit can identify a malfunction at least of the contactless detection device, when the first item of information has an active value while the second item of information has an inactive value. The invention allows redundancy to improve the availability of the detection device, while performing predictive maintenance for the operator, in particular a malfunction of the contactless sensor.
