1、電動機不動或轉速慢此故障原因一般是線路短路、電動機燒壞、停止按鈕未復位、限位開關動作、負載等引起的。

1. The cause of motor failure or slow speed is usually caused by a short circuit in the circuit, motor burnout, failure to reset the stop button, limit switch action, load, etc.

處理方法：檢查電路，并放上；更換燒電機；更改按鈕或重復按幾次；撥限位開關滑塊，將其從微動開關接觸點移開，并調整微開關位置；檢查機械部分有無卡陰，如有，則將卡陽清洗除去。

Processing method: Check the circuit and place it on; Replace the burning motor; Change the button or press it multiple times; Move the limit switch slider away from the microswitch contact point and adjust the microswitch position; Check the mechanical part for any sticking points, and if so, clean and remove the sticking points.

2、控制失效故障發生的部位及原因：.繼電器牽引器觸點接觸脫膠，行程微動開關失效或接觸變形，滑動緊固螺釘松動，后螺釘松開使滑塊或螺母不能與螺釘轉動，制動齒輪斷裂，按鍵，下匙卡死。

2. The location and cause of control failure: The contact of the relay traction device is out of contact, the travel micro switch is ineffective or deformed, the sliding fastening screw is loose, the rear screw is loose, making the slider or nut unable to rotate with the screw, the brake gear is broken, the button, and the lower key 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。

Handling method: Replace the relay (contactor); Replace microswitches or contacts; Tighten the slider screws and reset the backup plate; Replace the transmission gear of the limiter; Replace the button.

3、手拉鏈不動故障原因：環鏈塊十字槽；棘爪不能從鏟輪上脫落；壓鏈架卡死。處理：環鏈；調整棘輪和鏈架的相對位置；更換或潤滑銷軸。

3. Reason for the malfunction of the hand zipper not moving: cross groove of the chain block; The pawl cannot detach from the shovel wheel; The chain holder is stuck. Handling: Chain Link; Adjust the relative position of the ratchet and chain frame; Replace or lubricate the pin shaft.

4、電機振動或噪聲較大故障原因：剎車盤不平衡或斷裂；剎車盤無緊固；軸承失油或失效；齒輪哦合不順、失油或磨損嚴重；電機電流聲或振動。

4. Causes of motor vibration or loud noise: brake disc imbalance or fracture; The brake disc is not tightened; Loss of oil or failure of bearings; Improper engagement, oil loss, or severe wear of gears; Motor current sound or vibration.

處理方法：更換剎車盤或再平衡；緊固制動盤螺母；更換軸承；固定電機軸輸出端輪，潤滑或更換；檢查電機，如果電機損壞，則更換。

Solution: Replace the brake disc or rebalance; Tighten the brake disc nuts; Replace bearings; Fix the output end wheel of the motor shaft, lubricate or replace it; Check the motor and replace it if it is damaged.

5、檢查電動卷簾門的支位偏差及螺松緊情況，檢查皮帶的松緊情況，檢查控制器是否清潔電機出風箱內的潤滑油；粉塵檢查自動電動門組件的磨損情況——高速門、開閉寬度、速度、制動等。檢查電壓參數是否正常維修，更換受損部件。使用過程中難免會發生問題。

5. Check the support deviation and screw tightness of the electric roller shutter door, check the tightness of the belt, and check whether the controller is clean of the lubricating oil in the motor outlet box; Dust inspection for wear of automatic electric door components - high-speed doors, opening and closing width, speed, braking, etc. Check if the voltage parameters are normal for maintenance and replace damaged components. Problems are inevitable during use.

6、濟南電動卷簾門安裝維修人員提醒，如果長期缺乏保養，導致電動卷簾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；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。

6. Jinan electric roller shutter door installation and maintenance personnel remind that if there is a long-term lack of maintenance, which leads to the existence of hidden dangers and small faults of the electric roller shutter door can not be handled in time, the motor gets a certain running current and then runs forward to transmit power to the Timing belt, and then the Timing belt transmits power to the sling system to open the door leaf; After the door is opened, the controller makes a judgment. If the door needs to be closed, the motor is notified to move in reverse and close the door. It will change from a minor malfunction to a major malfunction, which may eventually lead 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.

7、內部的流動性。你可能需要安裝一個電動百葉窗來結束一個或多個室內門以及。操作人員應時刻注意伸縮門體的操作，以避免發生事故。應經常清理軌道，以避免雜物堆積影響作業。

7. Internal liquidity. You may need to install an electric louver to end one or more indoor doors as well. Operators should always pay attention to the operation of the telescopic door body to avoid accidents. The track should be cleaned regularly to avoid debris accumulation affecting the operation.

8、驅動器每年少潤滑一次，鏈條應定期潤滑，部件應進行磨損，任何嚴重磨損的部件必須及時修理或更換。

8. The drive should be lubricated at least once a year, the chain should be lubricated regularly, the components should be worn out, and any severely worn components must be repaired or replaced in a timely manner.

因為電動卷簾門造型美觀、功能齊全、控制方便、停電時也可手動操作，它的使用已經非常廣泛，很多門店，工廠、銀行、車庫等地方隨處可見電動卷簾門。更多事項就來我們網站//domachine.com.cn咨詢了解！
