Door sensor with self-diagnosing function |
摘要 |
A door panel is actuated when an actuator sensor disposed near the door panel senses an object approaching the door panel. When a safety sensor mounted on the door panel senses an object while the door panel is opening, the door panel is stopped. When a safety sensor mounted on the door panel senses an object while the door panel is closing, the door panel is opened. Each of the sensors includes a light-emitting unit, a light-receiving unit and a control unit, and the sensor can detect for itself failure in any of the light-emitting unit, the light-receiving unit and the control unit.
