Reasons why automatic induction doors cannot close automatically and how to deal with them

2015-8-18 16:16:33 Article source: http://junpairhy.com/click :
There are two cases where the automatic door cannot close automatically:
是门禁系统继电器损坏。 The first type: the automatic door is always open. The cause of this problem may be the damage of the sensor, and the door open signal is always input to the automatic door controller. It may be that the automatic door remote control or the mode switch is adjusted to the open state. If the access control system is installed, the access control system relay may be damaged.
The second is the case where the door moves but cannot be closed. This reason is that the sensor has a door open signal input, that is, there is interference in the sensor's sensing range. Compared with: direct sunlight, moving objects, Unstable light source, etc.
Through the above analysis, you should basically be able to solve the automatic door failure that you have proposed. The actual automatic door maintenance should be simple and complicated. First, remove the simple cause of the failure, and then gradually troubleshoot. The other is that the automatic door is always open.

)或有不稳定光源:相比日光灯等。 Cause analysis: Most of these failures are caused by accidental interference caused by accidental interference of this type of sensor that senses flowing objects. Compared with moving objects or reflective objects in the sensing range (compared to direct sunlight, sunlight Smooth glass marble, etc. within the sensing range ) or unstable light sources: compared to fluorescent lamps, etc. There are also a few reasons for the aging or damage of the automatic door accessory products described above, but most of them are the interference of the sensor, not the actual sensor damage. Will cause abnormal opening and closing of automatic doors.
Specific failure analysis: After the automatic induction door is fully opened, the door leaf cannot be closed normally. Sometimes the door action is opened again immediately, sometimes it can be closed half or almost completely closed, and sometimes even an abnormality occurs when the door is closed. .
过而仍旧引起自动门开关异常,就只能更换相应自动门感应器了。 Solution: According to the above analysis, a targeted solution is a matter of course. Remove flowing objects when there are moving objects, treat reflective objects on reflective surfaces to avoid interference, and replace incandescent lamps with unstable light sources. Stabilize the light source. When these reasons are corrected and the automatic door switch is still abnormal, you can only replace the corresponding automatic door sensor.
