1.先找出电动卷帘门的限位器所在的位置，然后用扳手将电动卷帘门上的一个固定螺钉松开，然后手动将卷帘门摇动。接着将电动卷帘门限位器上的螺钉再旋转，调整相应的位置，听到“滴答”一声后就不易拧紧，不是螺钉紧固。电卷帘门的限位调整不是一次就能成功的操作，所以要不断地上下调整卷帘门的位置，防火卷帘门然后再重复地进行松紧限制器的操作，直到Z后调整到合适的位置为止。

1. First, locate the position of the limiter for the electric roller shutter door, then use a wrench to loosen one of the fixing screws on the electric roller shutter door, and manually shake the roller shutter door. Next, rotate the screw on the limit switch of the electric roller shutter door again and adjust the corresponding position. After hearing a "tick" sound, it is not easy to tighten it, not the screw. The limit adjustment of the electric roller shutter is not successful once, so the position of the roller shutter shall be adjusted up and down continuously, and the fire roller shutter shall be operated repeatedly until it is adjusted to the appropriate position after Z.

2.调一个电动卷帘门限位器时，要检查遥控器是否能正常工作，电动卷帘门是否能收到遥控器的信号，而要进行升降操作，有问题要及时调整。

The lifting operation should be carried out, and any problems should be adjusted in a timely manner.

3.在试机前，需要将限位上的螺丝松开，并用手拉出环状链条，让门帘离地约1 m。然后，试着按“上、停、下”等键，并仔细观察卷门的升、停、降等各项功能是否灵敏。

Before testing the machine, it is necessary to loosen the screws on the limit and pull out the circular chain by hand, so that the door curtain is about 1 meter above the ground. Then, try pressing the "up, stop, down" buttons and carefully observe whether the functions of the rolling door, such as lifting, stopping, and lowering, are sensitive.

如果一切都正常，下一步你可以把门帘抬起或降到确定的位置，旋转螺套，调整触头，直到微动开关滚轮，听到“滴答声”将螺钉拧紧。Z终，经过反复调试，如果限位达到了z好的位置，只需拧紧螺钉即可。

If everything is normal, the next step is to lift or lower the door curtain to the designated position, rotate the screw sleeve, adjust the contacts, until you hear a "ticking sound" on the microswitch roller and tighten the screws. After repeated debugging, if the limit reaches the good position of Z, just tighten the screw.
