What if the electric rolling shutter door can't be closed? Fault causes and treatment methods.

故障原因及處理方法如下：

The fault causes and treatment methods are as follows:

1.電動卷簾門不動或轉速慢，原因：線路斷開、電機燒壞、停止按鈕未復位、限制開關動作、負載過大等。處理方法：檢查線路、并接通；更換燒損電機；更換按鈕或多次按動；撥動開關的限位滑塊與微動開關接觸點分開，調節微動開關位置；檢查機械部分是否有卡阻，如果有，卡阻障礙。2.控制失效故障的故障位置和原因：繼電器(接觸器)觸點粘合、行程開關失效或觸片變形.滑塊松開螺釘松開、靠板螺釘松開，靠板移動。滑塊或螺母在轉動時不能移動、限制器驅動齒輪損壞、按按鍵。處理方法：更換繼電器(接觸器)；更換一個微動開關或觸片；緊固滑塊螺釘，使靠盤復位；更換限位齒輪；更換按鈕。

1. The electric rolling shutter door does not move or the speed is slow. The reasons are: the line is disconnected, the motor is burnt out, the stop button is not reset, the limit switch acts, the load is too large, etc. Treatment method: check the line and connect it; Replace the burned motor; Replace the button or press it for many times; The limit slider of the toggle switch is separated from the contact point of the microswitch to adjust the position of the microswitch; Check whether there is jamming in the mechanical part. If so, eliminate the jamming and remove the obstacles. 2. Fault location and cause of control failure: relay (contactor) contact bonding, travel switch failure or contact deformation Loosen the screw of the slider and the screw of the backup plate, and the backup plate moves. The slider or nut cannot move when rotating, the limiter driving gear is damaged, and press the key. Treatment method: replace the relay (contactor); Replace a microswitch or contact piece; Tighten the slider screw to reset the backup plate; Replace the limit gear; Replace the button.

3.手拉鏈不動故障原因：環形鏈條堵塞十字槽；棘爪未脫離棘輪；壓鏈架卡死。處理方法：理順環鏈；調整棘爪與壓鏈的相對位置；替換銷軸或潤滑。4.電動機振動或噪聲大的原因：制動器不平衡或破裂；制動器未緊固；軸承漏油或失效；齒輪嚙合不良.油污或磨損嚴重；電機電流或振動。處理方法：更換制動盤或重新調整平衡；緊固制動盤螺母；更換軸承；更換電機軸輸出.潤滑或更換電機；檢查電動機，如果電機損壞，則更換。

3. Failure cause of hand zipper immobility: the ring chain blocks the cross groove; The pawl is not separated from the ratchet wheel; The chain pressing frame is stuck. Treatment method: straighten out the chain; Adjust the relative position between the pawl and the pressure chain; Replace the pin or lubricate it. 4. Causes of high motor vibration or noise: unbalanced or broken brake; The brake is not fastened; Oil leakage or failure of bearing; Poor gear engagement Oil stain or serious wear; Motor current or vibration. Treatment method: replace the brake disc or readjust the balance; Tighten the brake disc nut; Replace the bearing; Replace the motor shaft output Lubricate or replace the motor; Check the motor and replace it if it is damaged.

電動卷簾門沒有進行日常維修和保養。

The electric rolling shutter door was not repaired and maintained daily.

日常所用損耗還需定期清理維護，以免故障無法及時發現。可能需要安裝電控卷閘門結束的一個或多個室內門。在任何時候，操作人員都要注意伸縮門的工作狀況，以免發生事故。清掃道岔時要經常清潔，以免雜物堆積影響操作。傳動裝置每年少要加一次潤滑脂，鏈條要經常加油，檢查各部件磨損情況，對磨損嚴重的機件要及時維修或更換。

The daily losses also need to be cleaned and maintained regularly, so as to prevent the failure from being found in time. It may be necessary to install one or more indoor doors at the end of the electric rolling gate. At any time, operators should pay attention to the working condition of the telescopic door to avoid accidents. The turnout shall be cleaned frequently to avoid the accumulation of sundries affecting the operation. The transmission device shall be greased at least once a year, the chain shall be frequently oiled, the wear of each component shall be checked, and the severely worn parts shall be repaired or replaced in time.
