The entrance must remain open until the area is
clear of pedestrians.
If the area is clear, then the gate must close
automatically after one minute.
Standard solution
As long as the detector B1 or B2 detects someone
approaching, the switch, K3 will be on and open the door.
If the two detectors don’t detect a person after a short
time, trigger K4 and close the door.
