电动卷帘门在使用的过程中，难免会遇到这样或那样的问题。可不要一遇到问题就打电话报修，有很多小问题，自己动动手，分分钟就解决了。我们把之前客户经常遇到的一些小问题搜集在一起，又咨询了济南卷帘门厂的技术人员，总结了几个技巧：

In the process of using the electric Roller shutter, it is inevitable to encounter problems of one kind or another. Don't call and report any problems as soon as you encounter them. If there are many small problems, take action and solve them in minutes. We collected some small problems that customers often encountered before, and consulted the technicians of the Roller shutter factory in Jinan, and summarized several skills:

01

01

帘布忽上忽下不停

The curtain fabric keeps moving up and down

这种问题可能是机械有卡死或者润滑不良导致的，检查一下机械负载。机械可能有共振现象，调整载波，改变减速比，避开共振频率，加装减震垫片即可。别急着报修，先调试。

This problem may be caused by mechanical jamming or poor lubrication. Check the mechanical load. Mechanical resonance may occur. Adjust the carrier wave, change the reduction ratio, avoid resonance frequency, and install shock absorbers. Don't rush to report for repairs, debug first.

卷帘门向上时卡顿

Stuck when the Roller shutter is upward

常见的是轴承问题。如果不能确定是否是轴承问题，建议先把负载和电机脱开。以确定是电机问题还是负载问题。开电和没上电前都要用手转下电机，检查是否有卡阻感。电机有卡阻感，电机连接线没碰到一起那就是控制器坏了。如果电机有转动声，但不见门体运行，那有可能是需要更换电容。如排除了电机问题，那有可能是门体运行轨道有杂质，这些杂质的存在会导致门体的运行受阻。

A common issue is with bearings. If it is uncertain whether it is a bearing issue, it is recommended to disconnect the load from the motor first. To determine whether it is a motor issue or a load issue. Before turning on or off the power, manually rotate the motor to check for any jamming. The motor has a jamming feeling, and if the motor connecting wires do not touch each other, it means that the controller is broken. If the motor makes a rotating sound but the door body is not running, it is possible that the capacitor needs to be replaced. If the motor problem is ruled out, it is possible that there are impurities in the running track of the door body, which can cause the operation of the door body to be hindered.

卷帘布总会不受控地下滑

Rolling curtains always slide uncontrollably

可能是抱闸或是卡住机械的东西坏了，还有可能是抱闸不紧导致的，不能抱住卷闸门，电动卷闸门应有个机械抱死的部件，就是能卡住卷闸门卷轴的那个。检查一下，如果确实是坏了，就需要更换一个，如果只是偶然一次没卡死，可以重新上下调试一下。

It may be due to the brake or something stuck in the machinery that is broken, or it may be due to the brake not being tight enough to hold the rolling gate. The electric rolling gate should have a mechanical locking component that can hold the rolling gate shaft. Check it out, if it is indeed broken, it needs to be replaced. If it doesn't get stuck by chance, you can debug it up and down again.

遥控打不开卷帘门

The remote control cannot open the Roller shutter

安装调试的时候有没有问题，如果安装调试没问题的话，一般电机和卷轴也不会有问题。那么通常会考虑无线遥控的问题。遥控器有没有设置好、是否有电、有没有损坏。如果是一樘很老的、使用时间很久的卷帘门，又排除了遥控器的问题，那么就用开关操作一下，听一下电机是否还在工作。电机没有声音，卷轴也不工作，那么就需要考虑更换电机了。

Are there any problems during installation and debugging? If there are no problems during installation and debugging, generally the motor and winding shaft will not have any problems. So the issue of wireless remote control is usually considered. Is the remote control set properly, powered, and damaged. If it is a very old Roller shutter with a long service life, and the problem of the remote control is eliminated, use the switch to operate it and listen to whether the motor is still working. The motor has no sound and the winding shaft is not working, so it is necessary to consider replacing the motor.

卷帘门为何点一下动一下

Why did the Roller shutter move a little

通常是因为模式设置为“点动”模式了，可以重新进入行程设置，对模式进行修改。修改为“手动”或者“自动”。

Usually, because the mode is set to "jog" mode, you can re-enter the travel setting and modify the mode. Change to "manual" or "automatic".

电动卷帘门无法向上

Electric Roller shutter fails to move upwards

排除电机问题，通常考虑控制键坏了，需要打开控键盒面板，进行检修。

When troubleshooting the motor, it is usually considered that the Control key is broken, and the control box panel needs to be opened for maintenance.

卷帘一边高一边低

The roller shutter is high on one side and low on the other

排除安装时没装好的可能，或者有硬物阻塞。需要检查一下卷帘行进的通道。还有什么疑惑或者需求，随时来我们网站http://www.jnhsjlm.com做咨询！
