The reason why the rolling shutter door of garage has a large dynamic opening is that the remote control of garage door selects the triple system (3-phase) for the purpose of transmission. They are equipped with printed circuit boards based on crystal or submerged arc welding to meet severe EMC requirements. The remote controls (types 94335e, 94330e and 94333e) are equipped with two 3V lithium batteries (CR2032). The battery life is five years. When the remote control is activated, it generates a pulsating radio signal.

當開門機中的接收機拾取到信號時，它把信號與存儲的代碼作比較。接收機驗證編碼兩次。假設它承受代碼，則會建議開門機。接收機解碼器的照應時刻為0.3秒-從建議遙控器到翻開車庫門。

When the receiver in the door opener picks up the signal, it compares the signal with the stored code. The receiver verifies the code twice. Assuming it bears the code, a door opener is recommended. The receiver decoder takes care of 0.3 seconds - from the recommended remote control to the garage door.

電動車庫門翻開動態大的原因剖析

Analysis of the reason for the dynamic opening of electric garage door

1.合頁、軌跡等的固定螺絲松動。查看固定合頁和導軌的螺絲看是否松動，如有松動，用老虎鉗上緊

1. The fixing screws of hinges and tracks are loose. Check the screws that fix the hinge and guide rail to see if they are loose. If they are loose, tighten them with a vise

2.設備車庫門時，沒有保持在一個水平方位，門板一邊靠近軌跡，另一邊遠離導軌，導致門體上升過程中，門板上的鉸鏈和導軌之間沖突力增大，然后發生吱吱的噪音。解決方法，調整兩端導軌，確保門板在兩端導軌正中間。

2. When the garage door is installed, it is not kept in a horizontal position. One side of the door panel is close to the track, and the other side is far away from the guide rail. As a result, the collision force between the hinge on the door panel and the guide rail increases, and then squeaking noise occurs. The solution is to adjust the guide rails at both ends to ensure that the door plate is in the middle of the guide rails at both ends.

3.門板側邊鉸鏈上面悉數涂上潤滑油，特別留神鉸鏈和軌跡對應的那一周圍面、鉸鏈孔內部都要加潤滑油

3. All the hinges on the side of the door panel shall be coated with lubricating oil, especially the surrounding surface corresponding to the hinge and track, and the inside of the hinge hole
