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，若有则卡阻清理障碍物。

Solution: Check the circuit and connect it; Replace the burnt out motor; Replace the button or press it repeatedly several times; Move the limit switch slider to detach it from the microswitch contacts and adjust the microswitch position; Check if there is any jamming in the mechanical part, and if there is, eliminate the jamming and clean the obstacles.

控制失效故障

Control failure fault

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。

Location and cause of occurrence: The contact of the relay (contactor) is stuck, the travel micro switch is ineffective or the contact piece is deformed, the fastening screw of the slider is loose, and the screw of the support plate is loose, causing the support plate to shift, making the slider or nut unable to move with the screw rotation, the transmission gear of the limiter is damaged, and the up and down 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。

Solution: Replace the relay (contactor); Replace the microswitch or contact pad; Tighten the slider screw and reset the support plate; Replace the transmission gear of the limiter; Replace the button.

手拉链不动

Hand zipper not moving

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。

Cause of malfunction: The circular chain is blocking the cross groove; The pawl does not detach from the ratchet; The chain holder 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。

Solution: Smooth out the circular chain; Adjust the relative position between the pawl and the chain press frame; Replace or lubricate the pin shaft.

电机振动或噪声较大

Excessive motor 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。

Cause of malfunction: Unbalanced or broken brake discs; The brake disc is not tightened; Loss of oil or failure of bearings; Uneven meshing, oil loss or severe wear of gears; Motor current sound or vibration.

处理方法：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。

Solution: Replace the brake discs or readjust the balance; Tighten the brake disc nuts; Replace bearings; Repair, lubricate or replace the gear at the output end of the motor shaft; Check the motor and replace it if it is damaged.

检查电动卷帘门的支位偏差及螺丝松紧情况。

Check the support deviation and screw tightness of the electric roller shutter door.

检查皮带的松紧情况，检查控制器对电机输出清洁机箱内部的油污、 灰尘检查自动电动门各部件的磨损情况高速门，开关门宽度、速度、制动等情况检查电压参数是否正常维修、更换损坏的部件业主还需注重自动门的定期保养与维护，自动门由于受安装质量及使用环境的影响，使用过程中难免会发生问题。

Check the tightness of the belt, clean the motor output of the controller, and check the oil and dust inside the chassis. Check the wear of various components of the automatic electric door. For high-speed doors, check the width, speed, and braking of the opening and closing doors. Check whether the voltage parameters are normal. Repair and replace damaged components. The owner also needs to pay attention to the regular maintenance and upkeep of the automatic door. Due to the influence of installation quality and usage environment, the automatic door is affected, Problems are inevitable during use.

如果长期缺乏保养，导致电动卷闸门存在的隐患及小故障得不到及时处理，马达得到一定运行电流后做正向运行，将动力传给同步带， 再由同步带将动力传给吊具系统使门扇 开启；门扇开启后由控制器作出判断，如需关门，通知马达作反向运动，关闭门扇。将会由小故障变成大故障，终可能导致自动电动门的瘫痪。感应探测器探测到有人进入时，将 脉冲信号传给主控器，主控器判断后通知马达运行，同时监控马达转数，以便通知马达在一定时候加力和进入慢行运行。

If there is a long-term lack of maintenance, the hidden dangers and small faults of the electric roller gate cannot be dealt with in a timely manner. After receiving a certain operating current, the motor operates in a forward direction, transmitting power to the synchronous belt, which then transmits power to the lifting system to open the door leaf; After the door leaf is opened, the controller makes a judgment. If it needs to be closed, the motor is notified to move in reverse and close the door leaf. It will transform from a minor malfunction to a major one, ultimately leading to the paralysis of the automatic electric door. When the induction detector detects someone entering, it sends a pulse signal to the main controller. After the main controller judges, it notifies the motor to run and monitors the motor speed to notify the motor to apply force and enter slow operation at a certain time.

内部的流动性。你可能需要安装电动卷闸门终结一个或多个室内门以及。操作人员应随时留视伸缩门门体运行情况，以免发生意外。轨道内应经常清扫，以免杂物堆积影响运行。

Internal liquidity. You may need to install an electric roller shutter to terminate one or more indoor doors. Operators should always keep an eye on the operation of the telescopic door body to avoid accidents. The track should be cleaned regularly to prevent debris accumulation from affecting operation.

驱动器每年少要加注一次润滑脂，链条应经常加注润滑油，并检查各部件磨损情况，磨损严重的机件要及时维修或更换。

The driver should be lubricated at least once a year, and the chain should be lubricated regularly. The wear of each component should be checked, and severely worn parts should be repaired or replaced in a timely manner.
