1. The electric roller shutter door keeps moving up and down when it reaches the top

机械有卡死或者润滑不良，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。

If the machine is stuck or poorly lubricated, check the mechanical load. Mechanical resonance may occur. Adjust the carrier wave, change the reduction ratio, avoid resonance frequency, and install shock absorbers.

2、电动卷帘门总是卡顿

2. The electric roller shutter door always gets stuck

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.

3、电动快速卷帘门下到位了，却还自动下滑

3. The electric fast rolling shutter door is in place, but it still automatically slides down

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.

4、电动卷帘门遥控打不开

4. The remote control of the electric roller shutter door cannot be opened

，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。

Firstly, there are no issues during installation and debugging. If there are no issues during installation and debugging, generally there will be no problems with the motor and winding shaft. 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 and long used roller shutter door, and the problem with the remote control is eliminated, then use the switch to operate it and listen if 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.

5、电动卷帘门行程调法

5. Electric roller shutter door stroke adjustment method

先根据安装说明书上的知识，输入初始密码，进入“设置”，再进入“行程设置”，然后再根据自己的需求进行调整。

Based on the knowledge in the installation manual, enter the initial password, enter "Settings", then enter "Travel Settings", and then adjust according to your own needs.

6、卷帘门电动门内部线路如何检查

6. How to check the internal wiring of the electric roller shutter door

打开帘布右侧的“控制箱”进行检查。

Open the "control box" on the right side of the curtain for inspection.

7、电动卷帘门半夜自动开

7. Electric roller shutter door opens automatically at midnight

可能该电动移门安装了雷达感应器。夜间雷达碰到感应物，就自动打开了。建议夜间不使用卷帘门的情况下，更好是锁死，并切断电源。

Perhaps the electric sliding door is equipped with a radar sensor. At night, the radar automatically turns on when it encounters sensing objects. It is recommended to lock and cut off the power supply when not using the rolling shutter door at night.

8、电动卷帘门能不能改成手动的

8. Can the electric roller shutter door be changed to manual

可以，进入行程，进行模式设置，改为手动。

Yes, enter the travel mode and set the mode to manual.

9、电动卷帘门按一下动一下

9. Press and move the electric roller shutter door

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"

10、电动卷帘门向上不好使

10. The electric roller shutter door is difficult to operate 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。

To troubleshoot motor issues, it is usually considered that the control keys are broken and the control box panel needs to be opened for maintenance.

11、电动卷闸门一边高一边低

11. Electric roller shutter with one side high and one side low

排除按装时没装好的可能，或者有硬物阻塞。需要检查一下卷帘行进的通道。

Eliminate the possibility of not being properly installed during installation, or having hard objects blocking it. We need to check the passage of the roller shutter.

12、快速卷帘门检修那些项目

12. What are the maintenance items for fast rolling shutter doors

PVC快速卷帘门主要是要防撞柱断裂，帘布卡死下不来，内外压差太大运行不畅，滚筒脱焊，控制器不灵等。

The main purpose of PVC fast rolling shutter doors is to prevent collision column breakage, stuck curtain fabric, large internal and external pressure difference, poor operation, roller detachment, and ineffective controller.
