Now the rolling shutter door is more and more popular, and has already become a necessary equipment and facilities for many industrial enterprises. However, in the process of using the rolling shutter door, it is always inevitable to encounter some small problems, which makes users very annoyed. For example, if the rolling shutter door cannot be closed, you should first know what causes the rolling shutter door to fail to close. Next, the editor of Jinan roller shutter factory will talk about the reasons why roller shutter doors cannot be closed.
1、自动状态下，超越设定延时封闭时刻，门体仍然未下降，查看红外线的指示灯是赤色仍是绿色，绿色为正常状态，赤色表明故障，恰当调整红外线位置直到绿灯亮为止。
1. In the automatic state, the door body is still not lowered beyond the set delay closing time. Check whether the infrared indicator light is red or green. Green is the normal state. Red indicates failure. Adjust the infrared position properly until the green light is on.

2、要查看地感控制器，如果地感控制器的绿灯长亮，此刻手自动开关均不能操作，须按住地感器上的复位键5秒钟以上，松开后红灯长亮，绿灯灭，如复位后绿灯仍然长亮，请查看地感线圈周围是否有相应体积铁器。
2. To check the ground sensor controller, if the green light of the ground sensor controller is on for a long time, and the manual and automatic switches cannot be operated at this moment, you must press and hold the reset key on the ground sensor for more than 5 seconds. After releasing, the red light is on for a long time, and the green light is off. If the green light is still on after resetting, please check whether there is a corresponding volume of iron around the ground sensor coil.
3、门体重复运转，门体出现重复运转现象时，要查看门体在下降过程中是否有物体或帘体自身切断红外线状况，采纳相应方法扫除。
3. The door body runs repeatedly. When the door body runs repeatedly, it is necessary to check whether there is an object or the infrared ray cut-off condition of the curtain body itself in the process of falling, and adopt corresponding methods to sweep it.
4、门体有卡滞现象或门体吊带脱落。
4. The door body is stuck or the sling of the door body falls off.
卷帘门出现不能封闭的原因有如上几点，此外还有的用户会碰到卷帘门反复自动运行，无法封闭的情况，这是由于卷帘门在封闭的过程中，碰到物品堵截了两条相互对应的红外线，造成红外线被阻挡，导致门体无法封闭，挪开物品就可以了。更多相关内容就来我们网站http://www.jnhsjlm.com咨询了解吧。
The reasons why the roller shutter door cannot be closed are as follows. In addition, some users will encounter the situation that the roller shutter door repeatedly operates automatically and cannot be closed. This is because the roller shutter door blocks two corresponding infrared rays when it encounters objects in the process of closing, causing the infrared rays to be blocked, resulting in the door body cannot be closed. Just remove the objects. Come to our website for more relevant content http://www.jnhsjlm.com Consult and understand.
