注意觀察限位開關(guān)的動作變化和限位調(diào)整輪的運動變化。卷簾限位的控制，是通過轉(zhuǎn)動軸上兩個小輪的左右碰觸微動開關(guān)來實現(xiàn)的，左右移動兩個限位輪在運動的過程中，電動卷簾門下限位調(diào)節(jié)方法只需觸動微動開關(guān)即可實現(xiàn)。
Pay attention to observe the movement change of limit switch and the movement change of Limit Adjustment Wheel. The control of the roller shutter limit is realized by touching the micro-switch of the two small wheels on the rotating shaft. During the movement of the two limit wheels, the lower limit adjusting method of electric shutter door can be realized only by touching the micro-switch. 

卷簾下限調(diào)整方法：
Adjustment of the lower limit of the roller shutter:

先確定哪一種控制開關(guān)為下限位，一般濟南電動卷簾門升頂部，觀察哪一個微動開關(guān)處于“動作”狀態(tài)時，其為上限位開關(guān)，下限位開關(guān)。
First determine which kind of control switch for the lower limit, generally Jinan Electric Shutter door to the top, observe which micro-switch in the “Action”state, its for the upper limit switch, lower limit switch.

At the beginning of the reason, because the shutter program is set to two-level down, in accordance with the control panel debugging method, adjust for a step down.
