He is originally a combination of multiple detachable door pieces, which is more prone to failure. Now let's share some common faults of roller shutter door. I hope it will help you.

1、卷帘门无法正常工作，不能启动。可能是因为电动机内线路老化，所以出现了短路现象。还可能是电动机与卷帘门之间的皮带脱落，不能传输动力。或者是卷帘门被杂物卡住，不能升降，还可能是电动机的控制开关发生了故障，而不能正常传输信号了。

1. The roller shutter does not work properly and cannot be started. It may be that the circuit in the motor is aging, so there is a short circuit phenomenon. It may also be that the belt between the motor and the rolling shutter door falls off and cannot transmit power. Or the rolling shutter door is stuck by sundries and cannot be lifted or lowered, or the control switch of the motor fails to transmit signals normally.

2、卷帘门的开关速度过于缓慢，需要等待很久。

2. The opening and closing speed of the roller shutter door is too slow. It takes a long time.

①由于电动机内电压出现异常或者是电动机与卷帘门中间所连的皮带出现了松动现象。或者活动门与固定门和地板发生了摩擦所导致的；

① Because the voltage in the motor is abnormal or the belt between the motor and the roller shutter door is loose. Or the friction between the movable door and the fixed door and the floor;

②卷帘门在没有操控的时候自行打开或者关闭，原因是操控传感器发生了故障，或是传感器被其他物体干扰，不能正常接收到命令；

② The rolling shutter door opens or closes itself when it is not under control, because the control sensor fails, or the sensor is interfered by other objects, so it cannot receive the command normally;

③卷帘门在开关时发生抖动，并有刺耳的声音发出。可能是由于电动卷帘门移动轨道内有杂物，阻碍了滑轮的运动；

③ The rolling shutter door vibrates when opening and closing, and there is a harsh sound. It may be that there are sundries in the moving track of the electric rolling shutter door, which hinders the movement of the pulley;

④卷帘门门扇在向内关闭时有碰撞声音传出来。是因为电动卷帘门关闭的速度太快，或者电动机自身发生了故障。

④ There is a collision sound when the shutter door leaves are closed inward. It's because the electric roller shutter is closing too fast, or the motor itself fails.
