When we open door 1 to enter Airlock, the display light of door 1 will be green, meaning it can go and the display light of door 2 will be red, ie the door is forcibly closed, cannot open. OK. The open state of the door will be for a certain amount of time (about 6 seconds and adjustable) after a while, the lock will signal the need to close. Then we have to wait for 6s (the time has 2) can only open the second door. Until the lights of both doors turn green, we can start opening the second door to enter the clean room. When the 2nd door is opened to enter the clean room, the second door's light will be green, while the light of the 1st door will be red, meaning that it is not open. And after a certain period of opening, the lock will indicate closing.
