1、电动机不动或转速慢

1. The motor does not move or the speed is slow

故障原因：一般是线路断路、电机烧损、停止按钮没复位、限位开关动作、负载较大等引起。

Fault causes: generally, it is caused by open circuit of the line, burning of the motor, failure to reset the stop button, action of the limit switch, large load, etc.

处理方法：检查线路、并接通；更换烧损电机；更换按钮或重复按动几次；拨动限位开关滑块使它脱离微动开关触点，并调整微动开关位置；检查机械部分有无卡阻，若有则消除卡阻清理障碍物。

Treatment method: check the line and connect it; Replace the burned motor; Change the button or press it repeatedly for several times; Toggle the limit switch slider to separate it from the microswitch contact, and adjust the microswitch position; Check whether the mechanical part is blocked. If so, remove the blockage and clear the obstacles.

2、控制失效

2. Control failure

故障发生的部位及原因：继电器（接触器）触点粘死、行程微动开关失效或触片变形、滑块紧定螺钉松、靠板螺丝松使靠板移位，使滑块或螺母不能随丝杆转动而移动、限位器传动齿轮破损、按钮上、下键卡死。

The position and cause of the fault: the contact of the relay (contactor) is stuck, the travel microswitch is invalid or the contact piece is deformed, the fastening screw of the slider is loose, and the screw of the backup plate is loose, which makes the backup plate shift, so that the slider or nut cannot move with the rotation of the screw rod, the transmission gear of the limiter is damaged, and the upper and lower keys of the button are stuck.

处理方法：更换继电器（接触器）；更换微动开关或触片；紧定滑块螺钉并使靠板复位；更换限位器传动齿轮；更换按钮。

Treatment method: replace the relay (contactor); Replace the microswitch or contact piece; Tighten the slider screw and reset the backup plate; Replace the transmission gear of the stopper; Replace the button.

3、手拉链不动

3. Hand zipper does not move

故障原因：环形链条堵住十字槽；棘爪无脱离棘轮；压链架卡死。

Fault cause: the ring chain blocks the cross groove; The pawl has no disengagement ratchet; The chain pressing frame is stuck.

处理方法：理顺环形链条；调整棘爪与压链架相对位置；更换或润滑销轴。

Treatment: straighten out the circular chain; Adjust the relative position between the pawl and the chain pressing frame; Replace or lubricate the pin shaft.

4、电机振动或噪声较大

4. The motor has high vibration or noise

故障原因：刹车盘不平衡或断裂；刹车盘无紧固；轴承失油或失效；齿轮啮合不顺、失油或磨损严重；电机电流声或振动。

Fault cause: the brake disc is unbalanced or broken; The brake disc is not fastened; Bearing oil loss or failure; Gear meshing is not smooth, oil loss or serious wear; Motor current sound or vibration.

处理方法：济南电动卷帘门安装维修人员认为您应该更换刹车盘或重新调整平衡；紧固刹车盘螺母；更换轴承；修配电机轴输出端齿轮、润滑或更换；检查电机，如电机坏损则更换。

Treatment: Jinan electric roller shutter door installation and maintenance personnel think you should replace the brake disc or readjust the balance; Tighten the brake disc nut; Replace the bearing; Repair, lubricate or replace the gear at the output end of the motor shaft; Check the motor and replace it if it is damaged.
