Weak current College】 【automatic door common failure and troubleshooting.

First of all here to talk about is the automatic door sensors (Pan, automatic valve) pseudo fault, which is the result of external factors on the symptom, not the machine parts. If this is false, you own is very easy to fix; of course, if the judgment is host internal electrical or mechanical problems, we recommend that you contact the dealer from them as you are responsible for troubleshooting, and replacement parts, this is because each manufacturer has private each manufacturers and other manufacturers of accessories, products are not compatible.
A common pseudo fault: door stops running (fixed) * first to see if there is power to the automatic valve unit *.
1. check whether there is a moving door leaf mopping phenomenon, if it has this phenomenon, the door is difficult when it starts, the main controller for impaired while running protection role of door leaf stops running.
2. check the door leaf of Sling pulley parts are shedding from orbit, if it has this phenomenon and crew will walk; General who has happened (objects) and the door leaf impact, often appears this fault.
3. Please pay attention to induction of automatic door is installed on the "security light", due to security light light on dust cover can also cause malfunction, so that there is an automatic menzhu control incorrectly identified as objects in the middle of the door leaf to stop the door, not move.
Common pseudo failure II: door leaf do not stop switch
1. There may be activities objects into the sensor induction range, such as pedestrians, vehicles, colorful, potted plants and other things, even light reflection may cause malfunction of the sensor.
2. check induction probe to see if induction probe for the detection range is too down, causing the door is closed, the sensors and sensing to move the door leaf, the sensor unit for objects in the movement, and the door leaf to open again.
3. a detailed check induction automatic door there is no object to issue strong waves, because of the strong waves is also possible to make the sensor interference, taken as a result of incorrect operation.
4. check on the beam is of stainless steel cover, because if dithering cover jitter will make in the above sensors with jitter, resulting in sensors produce malfunction, do not stop switch door leaf.
Three common pseudo fault: door leaf moving sounds great, not smooth (this failure often at used longer auto-sensing door)
1. door leaf of Sling pulley for the long run but has some wear, if there is a slight wear, you can track and wheel once clean (clean up dirt track); you can also add to the pulley bearings a little Lube, but be careful not to automatic door tracks and pulley surfaces add lubricating oil, because oil is easier to add the track stick on dust, so that the wheel damage faster; and prone to slipping spreader pulley, hit the door.
2. check the automatic door hardware, such as partial Sling Sling joints loose phenomenon, simply back reinforcement.
3. check the bottom of the door leaf to wheel (only damper), such as loose or damaged also occur loud, reinforcement or replaced.
Four common pseudo fault: Mobile door leaf response slow
1. sensor detection range.
2. sensor internal dust, just need to clean the sensor.
3. move the door leaf of door weight exceeds the automatic door motor bearing, can also cause this phenomenon
