           由开门传感器提供触发信号给控制系统,控制系统根据快速卷帘门的当前位置发出指令给变频器,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,关闭通道,直到下一个开门信号再次打开。
    Provided by a door opening sensor trigger signal to the control system, control system according to the current position of the rapid rolling door sends out the instruction to the frequency converter, start driving motor make the curtain rise rapidly, the vehicles and pedestrians through the back door curtain down automatically and close the channel, until the next open signal to open again.
        快速卷帘门升降速度非常快,不能像钢制卷闸门一样直接启动停止,一般需要变频器来控制电机的转速。上升时越快越好,快到位时(20cm左右)需要有一个减速缓冲停止过程,以防止撞击轨道,防止夹人,降低噪音,这也是衡量快速卷帘门性能好坏的一个标准。
    Fast shutter door lifting speed is very fast, not like steel gate as direct start stop, the general need to control the speed of the motor frequency converter. Rise the sooner the better, faster in place (20cm or so) need to have a slow process of buffer stops to prevent hit track, prevent clamping, reduce the noise, a standard which is to measure the performance of rapid rolling door.
        防火卷帘门因在两侧人员无法操作侧除外分别设置手动按钮控制电动卷帘门配件的升、降、停,并应在防火卷帘门火灾时下降关闭后提升该防火卷帘门的功能,且该防火卷帘门提升到位后应能自动恢复原关闭状态。
    Fire shutter doors for on both sides are respectively provided personnel to operate side except manual button control of electric rolling door accessories up and down, stop, and should decline to boost the fireproof rolling shutter door after the closure of the function in the fire shutter doors fire, and the fire doors ascension in place should be able to automatically restore the original closed.
