电动卷帘门主要安装在工厂、工业车间等场所，如果长期使用的话，地磁环还是不可避免地会出现故障。接下来，厂家浅谈如何处理电动卷帘门地磁感应故障的问题。

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.

检查接收器故障：

Check for receiver failure:

自行开关或红色发光二极管发光的检测环不受控制。

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

可能原因：接地线故障;第二个检测环干扰;有物体在检测环中移动;

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

解决方案：与闪烁六次的解决方案相同。如果开关时输出继电器产生电感，也会导致故障。当这种情况发生时，必须使用干扰抑制器进行保护。

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.

电动卷帘门地磁连续闪烁。

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

可能原因：双列直插或开关设置不正确;

Possible cause: dual inline or incorrect switch setting;

解决方案：切断电源，取下外壳，更正双列直插式开关设置。

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

电动卷帘门地磁闪动两次。

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

可能原因：探测环太大或绕圈太多(探测环电磁的理想数据是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);

解决方案:更换检测环或减少绕组数量(通常3~5圈是合理的)，重置，更换敏感度开关，等待3秒左右，然后将敏感度开口改回原来设定的位置。如有必要，在操作前切断电源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.

电动卷帘门地磁闪动四次。

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

可能原因：探测环太小或绕圈数太少;

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

解决方案：增加地磁线的绕圈组数，然后重置。

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

电动卷帘门地磁闪动六次。

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

可能原因：检测环干扰、接地线故障或短路。

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

解决方案：修复检测环。如有必要，更换检测环或找到检测环附近的金属物体进行。然后重置并更改敏感开关，等待约3秒，然后将敏感开口更改为原始设置位置。如有必要，在操作前切断电源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.

地磁感应控制济南电动卷帘门的工作原理是通过车辆的金属部件改变环传感器的值，发送信号控制开启和关闭。因此，地磁感应通常用于车辆需要经常通过的地方。它具有操作简单、提高工作效率、安装成本低、无人员监督等优点。

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.
