With the development of high-speed rolling door series products, the reasonable requirements for door appearance, wind resistance, driving and control system, manufacturing process and service life are higher and higher. We are using the high-speed rolling shutter door, and we can't close it when we encounter a fault

1.檢查地感控制器：如果地感控制器的綠燈長亮，此時手自動開關均不能操作；須按住地感器上的復位鍵5秒鐘以上，松開后紅燈長亮，綠燈滅；如復位后綠燈仍然長亮，請檢查地感線圈周圍是否有相應體積鐵器；

1. First check the ground sense controller: if the green light of the ground sense controller is on for a long time, the manual automatic switch can not operate at this time; Press and hold the reset key on the ground sensor for more than 5 seconds. After releasing, the red light will be on for a long time and the green light will be off; If the green light is still on for a long time after reset, please check whether there is corresponding volume iron around the coil;
             

2.自動狀態下，超過設定延時關閉時間，門體仍然未下降，檢查紅外線的指示燈是紅色還是綠色，綠色為正常狀態，紅色表示故障，適當調整紅外線位置直到綠燈亮為止；

2. Under the automatic state, if the door still does not descend after the set delay closing time, check whether the infrared indicator is red or green. Green is normal state, red indicates fault, and adjust the infrared position properly until the green light is on;

3.門體有卡滯現象或門體吊帶脫落。

3. The door body is stuck or the sling falls off.

4．門體反復運行：門體出現反復運行現象時，檢查門體在下降過程中是否有物體或簾體本身切斷紅外線狀況，采取相應辦法排除。

4. Repeated operation of door body: when repeated operation of door body occurs, first check whether there is any object or curtain body cutting off infrared in the process of falling, and take corresponding measures to eliminate it.
