现在，卷帘门已经进入千家万户，电动卷帘门若无电，一般安装电机时都会有手动链条，方便停电时用来把门打开，前提是人和电机在同一边，如果门是弄着的，只是想把它锁上，只要拉一下电机尾部的手动离合就可以了，这样就可以利用门的重量把它锁起来。因此，一般都会看到电动卷闸门安装的时候，都会有一条锁链附着在电机上，其原因也只是为了方便宜断电才能使用。

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.

与此同时，部分电机还具有蓄电功能，可保证停电或无电时，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.

以下是济南卷帘门厂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、停电时门开着，去拉一条电机链，花点时间就能把门关上。但人们会被关在室内。

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、停电时门关着，人又在室内，去拉电机上的一条链条，花点时间就能开门。

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、断电时门关着，人又在外面，只有等来电才能解决。

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.

电卷帘门门帘由开门传感器提供触发信号给控制系统，控制系统根据卷闸的当前位置发出指令，启动驱动电机使门帘快速上升，车辆行人通过后门帘自动下降，直到下一个开门信号再次打开。卷闸门，顾名思义，起动速度很快，不能像钢制卷闸门那样直接停止，卷闸门一般需要变频器来控制电机的转速。

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.

电动卷帘门筒下端做包箱或吊顶时，必须安装可拆卸的活动盖板，在电动卷门机的一侧下端必须预留500×500mm活动大孔以供维修保养。

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.

电动卷帘门是以多关节活动门片串联，由电机组带动，在固定滑道内，以门扇上方卷轴为转动上下门。利用遥控器的控制实现窗帘的升、停、降动作。另外设有断电手动释放系统，在断电时，可用手摇杆使卷帘门升降。更多相关事项就来我们网站http://www.jnzxmy.com咨询吧！

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.jnzxmy.com Consult!
