電動卷簾門主要安裝在工廠、工業車間等場所，如果長期使用的話，地磁環還是不可避免地會出現故障。接下來，廠家淺談如何處理電動卷簾門地磁感應故障的問題。

Electric roller shutter doors are mainly installed in factories, industrial workshops and other places. If they are used for a long time, the geomagnetic ring will inevitably fail. Next, the manufacturer talks about how to deal with the geomagnetic induction fault of the electric roller shutter door.

檢查接收器故障：

Check for receiver failure:

自行開關或紅色發光二極管發光的檢測環不受控制。

The detection ring that switches on and off by itself or emits light from the red LED is not controlled.

可能原因：接地線故障;第二個檢測環干擾;有物體在檢測環中移動;

Possible cause: ground wire fault; The second detection loop interferes; An object moves in the detection ring;

解決方案：與閃爍六次的解決方案相同。如果開關時輸出繼電器產生電感，也會導致故障。當這種情況發生時，必須使用干擾抑制器進行保護。

Solution: the same as the solution of flashing six times. If the output relay generates inductance when switching, it will also cause fault. When this happens, interference suppressors must be used for protection.

電動卷簾門地磁連續閃爍。

The geomagnetic field of the electric roller shutter door flashes continuously.

可能原因：雙列直插或開關設置不正確;

Possible cause: dual inline or incorrect switch setting;

解決方案：切斷電源，取下外殼，更正雙列直插式開關設置。

Solution: cut off the power supply, remove the housing, and correct the dip switch settings.

電動卷簾門地磁閃動兩次。

The magnetic field of the electric roller shutter door flashes twice.

可能原因：探測環太大或繞圈太多(探測環電磁的理想數據是80~300uH);

Possible cause: the detection ring is too large or there are too many circles (the ideal electromagnetic data of the detection ring is 80~300uh);

解決方案:更換檢測環或減少繞組數量(通常3~5圈是合理的)，重置，更換敏感度開關，等待3秒左右，然后將敏感度開口改回原來設定的位置。如有必要，在操作前切斷電源5秒。

Solution: replace the detection ring or reduce the number of windings (usually 3~5 turns is reasonable), reset, replace the sensitivity switch, wait about 3 seconds, and then change the sensitivity opening back to the original set position. If necessary, cut off the power supply for 5 seconds before operation.

電動卷簾門地磁閃動四次。

The magnetic field of the electric roller shutter door flashes four times.

可能原因：探測環太小或繞圈數太少;

Possible causes: the detection ring is too small or the number of turns is too small;

解決方案：增加地磁線的繞圈組數，然后重置。

Solution: increase the number of winding groups of geomagnetic lines, and then reset.

電動卷簾門地磁閃動六次。

The magnetic field of the electric roller shutter door flashes six times.

可能原因：檢測環干擾、接地線故障或短路。

Possible causes: detection ring interference, ground wire failure or short circuit.

解決方案：修復檢測環。如有必要，更換檢測環或找到檢測環附近的金屬物體進行。然后重置并更改敏感開關，等待約3秒，然后將敏感開口更改為原始設置位置。如有必要，在操作前切斷電源5秒。

Solution: repair the detection ring. If necessary, replace the detection ring or find metal objects near the detection ring for removal. Then reset and change the sensitive switch, wait about 3 seconds, and then change the sensitive opening to the original setting position. If necessary, cut off the power supply for 5 seconds before operation.

地磁感應控制濟南電動卷簾門的工作原理是通過車輛的金屬部件改變環傳感器的值，發送信號控制開啟和關閉。因此，地磁感應通常用于車輛需要經常通過的地方。它具有操作簡單、提高工作效率、安裝成本低、無人員監督等優點。

The working principle of Jinan electric roller shutter door controlled by geomagnetic induction is to change the value of the ring sensor through the metal parts of the vehicle and send signals to control the opening and closing. Therefore, geomagnetic induction is usually used where vehicles need to pass frequently. The utility model has the advantages of simple operation, improved work efficiency, low installation cost and no personnel supervision.
