卷簾門電機不(bu)動或轉(zhuan)速慢(man)： 此故障原因一般是線路斷路、電機燒損、停止按鈕沒復位、限位開關動作、負載較大等引起。

處理方(fang)法(fa)：檢查線路、并接通；更換燒損電機；更換按鈕或重復按動幾次；檢查遙控控制模塊.撥動限位開關滑塊使它脫離微動開關觸點，并調整微動開關位置；檢查機械部分有無卡阻，若有則消除卡阻清理障礙物。

電(dian)機更(geng)換(huan)安裝：電動卷簾的電機與卷筒芯軸之間是由傳動鏈條來連接，電機地腳用螺釘固定在鏈輪支架板上。更換電機前，必須將卷簾門降至最低端或用支架將卷簾門撐住。一是卷簾門的制動是靠電機本體上的制動器來起作用，電機拆除后，卷簾門則沒有制動而自動下滑；二是可以使傳動鏈條放松，方便將鏈條取下。

更(geng)換(huan)電機的步驟：將電機接線做好標記然后拆除，將電機地腳螺絲擰松將傳動鏈條摘下，最后將電機地腳螺絲拆除將電機取出；新電機安裝順序相反，但要注意，電機安裝好后，其本體上的環形手拉鏈條應自然垂直向下，不得有卡阻現象。

Rolling shutter door motor fixed or slow speed: This fault is generally caused by circuit break, motor burnout, stop button not reset, limit switch action, load, etc.

Processing methods: check the circuit, and connect; replace the burned motor; change the button or press repeatedly several times; check the remote control module. Push the limit switch slider to make it out of the micro-switch contact, and adjust the position of the micro-switch; check whether there is a mechanical part of the sticking resistance, if there is, remove the sticking resistance to clear the obstacles.

Motor replacement and installation: electric curtain motor and reel mandrel are connected by transmission chain, motor foot is fixed on the sprocket bracket plate with screws. Before changing the motor, the shutter door must be lowered to the lowest end or the shutter door should be braced with the support. One is that the brake of the rolling shutter door is operated by the brake on the motor body. After the motor is removed, the rolling shutter door slides automatically without braking. The other is that the driving chain can be relaxed and the chain can be easily removed.

The steps of replacing the motor are: marking the connection of the motor and removing it, loosening the anchor screw of the motor to remove the drive chain, and finally removing the anchor screw of the motor to remove the motor; the installation sequence of the new motor is opposite, but it should be noted that after the motor is installed, the ring-shaped hand zipper on the motor body should be naturally vertical downward, not allowed. There is a blockage phenomenon.
