1、由于故障或移位，兩個傳感器之間出現通訊故障或無法互相通信。

1. Due to a malfunction or displacement, there is a communication failure or inability to communicate with each other between two sensors.

如果其中一個傳感器出現故障或者失靈，它將發送信號給門控電機，告訴它不要關閉門。因此，如果您遇到濟南車庫門無法完全關閉或關閉一半又自動打開的情況，一步應該是檢查傳感器是否因為人為或其他原因離開了軌道，如果是，請將其重新安裝回原位，并確保兩個傳感器之間保持水平。如果是傳感器故障，就需要更換傳感器。這種情況比較復雜，建議請相關人士進行維修。

If one of the sensors malfunctions or malfunctions, it will send a signal to the door control motor, telling it not to close the door. Therefore, if you encounter a situation where the Jinan garage door cannot be fully closed or partially closed and then automatically opens, the first step should be to check if the sensor has left the track due to human or other reasons. If so, please reinstall it back in place and ensure that the two sensors remain level. If it is a sensor malfunction, the sensor needs to be replaced. This situation is quite complex, it is recommended to hire relevant professionals for maintenance.

2、在傳感器正常工作的情況下，它們之間存在障礙物。

2. When the sensors are working properly, there are obstacles between them.

如果傳感器發射的信號在傳輸過程中遇到障礙物會出現什么情況呢？其中一個原因可能是，經過一段時間后，傳感器的信號發射或接收鏡頭上積滿了灰塵。因此，請用干抹布擦拭鏡頭，特別是鏡頭上的灰塵。當然，如果有其他障礙物，如存放在車庫中的輪胎、掃帚甚至一片葉子擋住了傳感器的信號發射路徑，也可能導致門無法關閉。

What happens if the signal emitted by the sensor encounters obstacles during transmission? One reason may be that after a period of time, the signal transmission or reception lens of the sensor is covered with dust. Therefore, please use a dry cloth to wipe the lens, especially the dust on the lens. Of course, if there are other obstacles, such as tires stored in the garage, brooms, or even a leaf blocking the signal transmission path of the sensor, it may also cause the door to fail to close.

大多數情況下，當門控電機在關閉門的過程中收到“不要關閉門”的信號時，它會將門拉回打開狀態，并在完全歸位后發出“滴答滴答滴答”的聲音，提示我們門不能安全關閉。

In most cases, when the door control motor receives a signal of "do not close the door" during the process of closing the door, it will pull the door back to the open state and emit a "click click click" sound after fully returning, reminding us that the door cannot be safely closed.

如果再次遇到這種情況，建議先簡單檢查家里的傳感器是否存在問題或周圍是否有障礙物，然后再考慮是否需要找維修人員，以免花費不必要的開銷。更多相關事項就來我們網站http://www.llswdz.com咨詢!

If you encounter this situation again, it is recommended to first briefly check if there are any problems with the sensors at home or if there are obstacles around, and then consider whether professional maintenance personnel are needed to avoid unnecessary expenses.
