1. Check the grounding induction coil. If the green light of the ground sensing controller is on for a long time, the manual and automatic switches of the fast automatic rolling shutter door will fail. During operation, you need to press and hold the restart button of the ground sensing controller for 5 seconds. Turn off the traffic lights, the red light will be on for a long time, and the door can be closed. If the green light is on for a long time, please check whether there are iron chips near the grounding sensor, remove the iron chips, and the door body returns to normal.

2、檢查快速自動快門的紅外指示器。如果設置門自動延遲關閉時間，快速自動快門不能下降或關閉，紅外燈為紅色，指示紅外位置異常。需要調整紅外線位置，直到故障排除，綠燈亮起，門才能正常關閉。

2. Check the infrared indicator of the fast automatic shutter. If the door automatic delay closing time is set, the fast automatic shutter cannot be lowered or closed, and the infrared light is red, indicating that the infrared position is abnormal. The infrared position needs to be adjusted until the fault is eliminated and the green light is on, so that the door can be closed normally.

3、檢查快門吊索、快門等部件脫落，快門無法關閉。操作時，應逐一檢查和可疑零件，確認正常。

3. Check that the shutter sling, shutter and other parts fall off and the shutter cannot be closed. During operation, check and remove suspicious parts one by one to confirm that they are normal.

4、快速自動快門不能升降。原因:可能是電源故障、電機故障或門本身堵塞。措施:檢查主電源、控制電源和電機，檢查門。

4. Fast automatic shutter cannot be raised or lowered. Cause: it may be power failure, motor failure or door blockage. Measures: check the main power supply, control power supply and motor, and check the door.

5、防火快速自動快門不降不升。理由：上下按鈕，接觸器觸頭線圈、限位開關、接觸器鎖常閉觸點。操作步驟:檢查上下按鈕、下或上接觸器觸頭開關和線圈，檢查限位開關、底部或上接觸器的常閉觸點。

5. Fireproof fast automatic shutter does not fall or rise. Reason: up and down buttons, contactor contact coil, limit switch, contactor lock normally closed contact. Operation steps: check the upper and lower buttons, lower or upper contactor contact switches and coils, and check the normally closed contacts of limit switches, bottom or upper contactors.

6、控制中心無法連接快門。原因:控制中心本身的控制裝置故障、控制模塊故障和聯動輸送線故障。過程:檢查控制中心控制單元本身、控制模塊和傳輸線路。

6. The control center cannot connect the shutter. Cause: control device failure, control module failure and linkage conveyor line failure of the control center itself. Process: check the control unit itself, control module and transmission line of the control center.
