現在，卷簾門已經進入千家萬戶，電動卷簾門若無電，一般安裝電機時都會有手動鏈條，方便停電時用來把門打開，前提是人和電機在同一邊，如果門是弄著的，只是想把它鎖上，只要拉一下電機尾部的手動離合就可以了，這樣就可以利用門的重量把它鎖起來。因此，一般都會看到電動卷閘門安裝的時候，都會有一條鎖鏈附著在電機上，其原因也只是為了方便宜斷電才能使用。

Now, the Roller shutter has entered thousands of households. If the electric Roller shutter has no power, it usually has a manual chain when installing the motor, which is convenient for opening the door in case of power failure, provided that the person and the motor are on the same side. If the door is held, just want to lock it, just pull the manual clutch at the tail of the electric machine, so that it can be locked with the weight of the door. Therefore, it is common to see a chain attached to the motor when installing an electric roller gate, and the reason is only for the convenience of power outage before use.

與此同時，部分電機還具有蓄電功能，可保證停電或無電時，也可照常使用。

At the same time, some motors also have a power storage function, which can ensure that they can still be used as usual when there is a power outage or no power.

以下是濟南卷簾門廠家提供的一些特定的小方法：

The following are some specific small methods provided by the manufacturer of Roller shutter in Jinan:

1、停電時門開著，去拉一條電機鏈，花點時間就能把門關上。但人們會被關在室內。

1. When there is a power outage, the door is open. Pull a motor chain and take some time to close the door. But people will be locked indoors.

2、停電時門關著，人又在室內，去拉電機上的一條鏈條，花點時間就能開門。

2. When the power outage occurs, the door is closed and the person is inside. Pull a chain on the motor and it takes some time to open the door.

3、斷電時門關著，人又在外面，只有等來電才能解決。

3. When the power is cut off, the door is closed and people are outside. Only by waiting for a call can we solve the problem.

電卷簾門門簾由開門傳感器提供觸發信號給控制系統，控制系統根據卷閘的當前位置發出指令，啟動驅動電機使門簾快速上升，車輛行人通過后門簾自動下降，直到下一個開門信號再次打開。卷閘門，顧名思義，起動速度很快，不能像鋼制卷閘門那樣直接停止，卷閘門一般需要變頻器來控制電機的轉速。

The electric Roller shutter curtain is provided with a trigger signal by the door opening sensor to the control system. The control system sends a command according to the current position of the roller shutter, starts the drive motor to make the curtain rise quickly, and the vehicle and pedestrian automatically descend through the rear curtain until the next door opening signal is opened again. The rolling gate, as the name suggests, starts quickly and cannot be stopped directly like steel rolling gates. Rolling gates generally require a frequency converter to control the motor speed.

電動卷簾門筒下端做包箱或吊頂時，必須安裝可拆卸的活動蓋板，在電動卷門機的一側下端必須預留500×500mm活動大孔以供維修保養。

When the lower end of the electric Roller shutter drum is used as a box or ceiling, a removable movable cover plate must be installed, and 500 must be reserved at the lower end of one side of the electric roller × 500mm movable large hole for maintenance and repair.

電動卷簾門是以多關節活動門片串聯，由電機組帶動，在固定滑道內，以門扇上方卷軸為轉動上下門。利用遙控器的控制實現窗簾的升、停、降動作。另外設有斷電手動釋放系統，在斷電時，可用手搖桿使卷簾門升降。更多相關事項就來我們網站http://www.yeesentw.com咨詢吧！

The electric Roller shutter is connected in series with multi joint movable door pieces, driven by the electric unit, and rotates the upper and lower doors in the fixed slide way with the roller above the door leaf as the center. Use the remote control to control the lifting, stopping, and lowering of curtains. In addition, there is a manual release system for power-off. In case of power-off, the Roller shutter can be raised and lowered with a hand rocker. For more related matters, come to our website http://www.yeesentw.com Consult!
