Signal Reset of Space Scanner

If I save the game when the space scanner outputs a green signal, the state of the space scanner may be reset when the game is loaded again. As I continued the game, the space scanner output a red pulse signal that caused my bunker door to open. So I had to set the buffer time to 0.1s before starting the game or save the game when the space scanner outputs a red signal.

（As shown in the picture, my closed bunker door has received a green signal. I must adjust the buffer time to 0.1s to prevent the bunker door from opening）
