故障原因：線路斷路、電機燒損、停止按鈕沒復位、限位開關動作、負載較大等引起。

Cause of malfunction: Circuit open circuit, motor burnout, failure to reset stop button, limit switch action, high load, etc.

處理方法：檢查線路、并接通；更換燒損電機；更換按鈕或重復按動幾次； 撥動限位開關滑塊使它脫離微動開關觸點， 并調整微動開關位置；檢查機械部分 有無卡阻，若有則卡阻清理障礙物。

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

發生的部位及原因：繼電器（接觸器）觸點粘死、行程微動開關失效 或觸片變形、滑塊緊定螺釘松、靠板螺絲松使靠板移位，使滑塊或螺母不能隨絲 桿轉動而移動、限位器傳動齒輪破損、按鈕上、下鍵卡死。

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.

處理方法：更換繼電器（接觸器）；更換微動開關或觸片；緊定滑塊螺釘并 使靠板復位；更換限位器傳動齒輪；更換按鈕。

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.

手拉鏈不動

Hand zipper not moving

故障原因：環形鏈條堵住十字槽；棘爪無脫離棘輪；壓鏈架卡死。

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

處理方法：理順環形鏈條；調整棘爪與壓鏈架相對位置；更換或潤滑銷軸。

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

電機振動或噪聲較大

Excessive motor vibration or noise

故障原因：剎車盤不平衡或斷裂；剎車盤無緊固；軸承失油或失效；齒輪嚙合不順、失油或磨損嚴重；電機電流聲或振動。

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.

處理方法：更換剎車盤或重新調整平衡；緊固剎車盤螺母；更換軸承；修配電機軸輸出端齒輪、潤滑或更換；檢查電機，如電機壞損則更換。

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.

檢查電動卷簾門的支位偏差及螺絲松緊情況。

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

檢查皮帶的松緊情況，檢查控制器對電機輸出清潔機箱內部的油污、 灰塵檢查自動電動門各部件的磨損情況高速門，開關門寬度、速度、制動等情況檢查電壓參數是否正常維修、更換損壞的部件業主還需注重自動門的定期保養與維護，自動門由于受安裝質量及使用環境的影響，使用過程中難免會發生問題。

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.

如果長期缺乏保養，導致電動卷閘門存在的隱患及小故障得不到及時處理，馬達得到一定運行電流后做正向運行，將動力傳給同步帶， 再由同步帶將動力傳給吊具系統使門扇 開啟；門扇開啟后由控制器作出判斷，如需關門，通知馬達作反向運動，關閉門扇。將會由小故障變成大故障，終可能導致自動電動門的癱瘓。感應探測器探測到有人進入時，將 脈沖信號傳給主控器，主控器判斷后通知馬達運行，同時監控馬達轉數，以便通知馬達在一定時候加力和進入慢行運行。

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.

內部的流動性。你可能需要安裝電動卷閘門終結一個或多個室內門以及。操作人員應隨時留視伸縮門門體運行情況，以免發生意外。軌道內應經常清掃，以免雜物堆積影響運行。

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.

驅動器每年少要加注一次潤滑脂，鏈條應經常加注潤滑油，并檢查各部件磨損情況，磨損嚴重的機件要及時維修或更換。

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.
