Medical automatic door will continue to open or close on their own, regardless of whether someone passes.
There may be moving objects into the induction sensor range of sensors, such as pedestrians, vehicles, flags and even shaking the shadows;
The detection range of the probe is too down. When the door is about to close, the probe and the sensor to the activities of the door, detection sensors mistakenly believe that there are activities through the object, resulting in re-opening the door;
The probe may be fixed on the beams of the beam jitter phenomenon, so that the probe along with jitter, resulting in non-stop switch door.
