In the daily use of the induction automatic door, the door leaf can't be closed normally, which will lead to serious security risks. Then what are the reasons for the induction automatic door can't be closed and the solutions, which are analyzed one by one below.
1. The detection signal line is short circuited. Confirm whether the door leaf is closed after removing the control signal line from the wiring terminal. If it can be proved that the signal line is wrongly connected, you need to replace the signal line.
2. The auxiliary light sensor (i.e. the infrared beam opposite to the left and right of the automatic door opening) works continuously. At this time, we can first confirm whether there is dirt in the light receiver, remove it if there is, and then detect whether the optical axis deviates from a straight line if there is not.
3. The sensor works continuously. To cause this consequence, first of all, we need to detect whether there are items causing automatic door malfunction in the detection range of the sensor. If there are, we need to remove the items causing automatic door malfunction. If not, we need to replace the sensor.
