很多朋友在安裝、使用卷簾門時，經(jīng)常會遇到一些故障，又不知道是什么原因造成的，也不知道該如何維修，今天就我自己修理卷簾門的故障跟大家聊聊

　　Many friends often encounter some malfunctions when installing and using rolling shutter doors, and they don't know what causes them or how to repair them. Today, I will talk to you about repairing the faults of rolling shutter doors myself

　　卷簾門容易出故障的位置就是導(dǎo)軌、卷軸、簾板及控制線路四項，前三項基本大家都可以搞定，就控制線路這一項，很多人還是有疑問。今天我碰到就是控制線路的故障。

　　The areas where rolling shutter doors are prone to malfunction are the guide rails, rollers, curtain panels, and control circuits. Most people can handle the first three items, but many still have doubts about the control circuit. Today I encountered a malfunction in the control circuit.

　　今天使用部門報到我這邊，說卷簾門無法上升，就按上升按鈕，還是在下降，導(dǎo)致卷簾門的門片脫軌，到現(xiàn)場后，手動升起卷簾門后，現(xiàn)場操作，確實如此，我們是內(nèi)、外兩扇門聯(lián)動控制，內(nèi)門正常，就外門無法上升，按照正常修理，我先檢查外門的兩個繼電器，線圈正常，懷疑是觸點問題，之前也發(fā)生這個故障，于是更換繼電器，試開，不行，檢查按鈕開關(guān)的觸點，也是正常。由于是聯(lián)動控制，于是我拆除內(nèi)門控制線路，單獨試外門，結(jié)果還是一樣，這就確定是外門的問題。

　　Today, the department reported to me that the rolling shutter door could not be raised, so I pressed the up button, but it continued to descend, causing the door panel of the rolling shutter door to derail. After arriving at the scene, I manually raised the rolling shutter door and operated it on site. It was indeed the case. We controlled the linkage between the inner and outer doors, and the inner door was normal, but the outer door could not be raised. According to normal repairs, I first checked the two relays of the outer door, and the coils were normal. I suspected it was a contact problem, which had occurred before. So I replaced the relay, tried to open it, but it did not work. I checked the contact of the button switch, which was also normal. Due to the linkage control, I removed the control circuit of the inner door and tested the outer door separately. The result was still the same, which confirmed that it was the problem with the outer door.

　　用萬用表量上升及下降的兩根控制線，沒有短路，問題應(yīng)該在電機后面的控制線路，一一檢查該位置的線路，沒有問題，這下腦子就蒙了！手動拉鏈條可以控制升和降，說明電機離合器正常，兩個繼電器也更換，上、下的行程開關(guān)也是正常，問題到底出在哪里？沒有檢查的是電容，這個電容是電機的啟動電容20UF，難道是電容引起嗎？沒有可用的電容更換，于是我把內(nèi)門的電容拆下來換上去，結(jié)果上升正常了！我從事維修工作已經(jīng)20多年了，還沒碰到過，電容的容量下降或壞了，會導(dǎo)致卷簾門不會上升。在市場上買了一個電容，恢復(fù)線路，卷簾門正常使用！

　　Use a multimeter to measure the two control wires for rising and falling, and there is no short circuit. The problem should be in the control circuit behind the motor. Check the circuit at that position one by one, and if there is no problem, your mind will be confused now! The manual zipper strip can control the up and down, indicating that the motor clutch is normal, the two relays have been replaced, and the up and down travel switches are also normal. Where exactly is the problem? The only thing not checked is the capacitor, which is the starting capacitor 20UF of the motor. Could it be caused by a capacitor? There was no available capacitor to replace, so I removed the capacitor from the inner door and replaced it, and the result showed that the rise was normal! I have been engaged in maintenance work for more than 20 years and have not encountered it before. If the capacity of the capacitor decreases or breaks, it will cause the rolling shutter door to not rise. I bought a capacitor in the market, restored the circuit, and the rolling shutter door is functioning normally!

　　不知各位在平時修理中是否或碰到跟我一樣的故障，往往就被我們忽視的部件，有可能就是問題所在！希望我的經(jīng)歷會給你們一些啟發(fā)！

　　I don't know if you have encountered the same faults as me during regular repairs, which are often overlooked components. It may be the problem! I hope my experience will give you some inspiration!

　　感謝觀看，我會每天發(fā)一些自己在工作中碰到的維修問題，關(guān)注我，一起交流經(jīng)驗！

　　Thank you for watching. I will post some repair problems I encounter at work every day, follow me, and exchange experiences together!
