1. Anti-clip: there are strip pressure sensors mounted at the entrance /exit columns, once the passenger is bumped by the rotor
wing, the door will stop immediately. Once the person leaves, the door resumes normal speed.
2. Anti-colide: on the top-front of the display case, there's one wide-rang infrared sensor. If the rotor wing approximates near
the passenger, the door will speed down and stop. When the passenger moves forward, the door will resume rotating again.
3. Emergent stop: in case of emergency, just press down the red button and the door will stop immediately. When emergency removed,
turn the button clock wise and the door will return to normal working.
4. Disabled: the disabled button can be used when there's disabled passing-by. The door will keep running one cycle at low speed
to ensure the safety.
