一、卷帘门故障现象：电机无法启动

1、 Fault phenomenon of rolling shutter door: The motor cannot start

卷帘门的电机是驱动的关键部分，如果电机无法启动，卷帘门就无法正常工作。可能的原因为电源未接通、电机损坏或电路接触不良。

The motor of the roller shutter door is a crucial part of the drive. If the motor cannot start, the roller shutter door will not function properly. Possible reasons may be power failure, motor damage, or poor circuit contact.

维修方法：

Repair method:

检查电源是否接通，检查电路是否接触良好。

Check if the power supply is connected and if the circuit is in good contact.

检查电机是否有损坏，如损坏需要更换新的电机。

Check if the motor is damaged, and if so, replace it with a new one.

二、卷帘门故障现象：门体卡住

2、 Fault phenomenon of rolling shutter door: The door body is stuck

卷帘门在升降过程中，如果出现卡住的情况，可能是由于轨道堵塞、门体变形或电机过载等原因。

If the roller shutter door gets stuck during the lifting process, it may be due to reasons such as track blockage, door deformation, or motor overload.

维修方法：

Repair method:

检查轨道是否堵塞，清理轨道内的杂物。

Check if the track is blocked and clean up any debris inside the track.

检查门体是否有变形，如有变形需校正。

Check if there is any deformation in the door body, and correct it if there is any deformation.

检查电机是否过载，如过载需减少负载。

Check if the motor is overloaded, and if it is overloaded, reduce the load.

三、卷帘门故障现象：遥控器失灵

3、 Fault phenomenon of rolling shutter door: remote control malfunction

卷帘门的遥控器是操作的关键工具，如果遥控器失灵，可能是电池电量不足、信号干扰或电路故障等原因。

The remote control of the rolling shutter door is a key tool for operation. If the remote control fails, it may be due to low battery power, signal interference, or circuit failure.

维修方法：

Repair method:

检查电池是否电量不足，更换新的电池。

Check if the battery is low and replace it with a new one.

检查周围是否有信号干扰，如有需移开干扰源。

Check for signal interference around and remove the interference source if necessary.

检查电路是否故障，如故障需进行维修。

Check if the circuit is faulty, and if so, repair it.

四、卷帘门故障现象：自动门反应迟钝

4、 Fault phenomenon of rolling shutter door: slow response of automatic door

自动卷帘门在感应过程中，可能会出现反应迟钝的情况，可能是由于感应器堵塞、电机力矩不足或门体重量过重等原因。

During the induction process, automatic rolling shutter doors may experience slow response, which may be due to sensor blockage, insufficient motor torque, or excessive weight of the door body.

维修方法：

Repair method:

检查感应器是否堵塞，清理感应器。

Check if the sensor is blocked and clean it.

检查电机力矩是否不足，如不足需更换电机。

Check if the motor torque is insufficient, and if it is insufficient, replace the motor.

检查门体重量是否过重，如过重需减少负载。

Check if the weight of the door body is too heavy. If it is too heavy, reduce the load.

卷帘门的故障可能有很多种，但是掌握了基本的维修方法，就能轻松应对大部分问题。在遇到故障时，要保持冷静，然后根据具体情况进行分析和维修。当然，如果对维修不熟悉，建议寻求人员的帮助，以免造成更严重的后果。

There may be many types of malfunctions with rolling shutter doors, but mastering basic maintenance methods can easily solve most problems. When encountering a malfunction, the first thing to do is to stay calm, and then analyze and repair it according to the specific situation. Of course, if you are not familiar with maintenance, it is recommended to seek professional assistance to avoid more serious consequences.
