卷帘门的限位开关有两个，一个是上限位，有一个是下限位，能够控制开关的开启和关闭，调节的时候有两个人来操作，一个人要在上边调节转动杠杆的位置，另外一个人需要调节卷帘门的上下。具体操作的时候，将上面的一个卡片拨动到适合的度数，能够脱离螺母或者松开上面的螺钉。将门将卷帘门调到合适的位置之后，再将螺母压住开关上的滚轮，能够听到咔嚓的一声，也就是卡片已经卡入到相应的槽中，这时候就可以将螺钉拧紧。如果位置不合适，还可以再进行调整，直到的位置为止。

　　There are two limit switches for the roller shutter door, one is the upper limit and the other is the lower limit, which can control the opening and closing of the switch. When adjusting, it is best to have two people to operate. One person needs to adjust the position of the rotating lever on the upper side, and the other person needs to adjust the up and down of the roller shutter door. When performing specific operations, move one of the cards on top to the appropriate degree to detach the nut or loosen the screw on top. After adjusting the roller shutter door to the appropriate position, press the nut onto the roller on the switch. A click can be heard, indicating that the card has been inserted into the corresponding slot. At this point, the screw can be tightened. If the position is not suitable, further adjustments can be made until the optimal position is reached.
