Common faults and troubleshooting techniques of glass automatic door

2015-4-27 09:44:56 Article source: http://junpairhy.com/click :
Common false failures 1: Door leaves stop running (not moving)
1. Check whether the moving door leaf is mopping. If this phenomenon occurs, the door is strenuous during startup. The main controller will mistakenly think that there is an obstacle and the operation protection function will stop the door leaf.
2. Check if the pulley of the door leaf falls off the track. If there is such a phenomenon, the unit will not be able to move. Generally, this fault often occurs after a person (object) collides with the door leaf.
3. Please pay attention to whether the induction automatic door is installed with "safety light". The dust cover on the safety light receiver will also cause malfunction. The main control of the automatic door mistakenly believes that there is an object in the middle of the door, so it stops closing and does not move.

Common false failures 2: The door leaf switches on and off by itself 1. There may be moving objects entering the sensing range of the sensor, such as the shaking of pedestrians, vehicles, flags, potted plants, and even the reflection of strong light may cause the sensor to malfunction.
2. Check the sensing probe to see if the detection range of the sensing probe is adjusted too downward. When the door leaf is closed, the sensor detects the moving door leaf. The sensor device mistakenly believes that something is moving and the door leaf opens again.
3. Check it carefully to see if there is a strong electric wave from the object near the induction automatic door, because the strong electric wave may also cause the sensor to be interfered and cause malfunction.
4. Check whether the stainless steel cover plate on the beam has a shake phenomenon, because if the cover plate shakes, the sensor mounted on it will also shake with it, which will cause the sensor to malfunction and the door leaf will keep turning.

Common false failure three: The door leaf is loud and not smooth when walking (this failure often occurs on automatic induction doors that have been used for a long time)
1. The door pulley's sling pulley has a certain amount of wear due to long-term operation. If only slight wear and tear occur, you can clean the track and the pulley once (to clean up the track dust); you can also add a little to the bearing of the pulley Lubricating oil, but please be careful not to add lubricating oil to the track and pulley surface of the automatic door. After adding oil, it is easier to make the track stick to dust, which will cause the pulley to be damaged faster. Happening.
2. Check the hardware spreader of the automatic door. If some of the spreader connectors are loose, just re-reinforce it. This article originated from: junpairhy.com
