6� Settings The switching distance to the object can be taught in for both outputs by pressing the teach-in key on the sensor (default setting is foreground teach-in). Teach-In for Switching Output 1 1. Mount the sensor in accordance with the mounting instructions. 2.
7�1�2 Background Teach-In Teach-In is performed while the sensor spot is aligned to the background. The switching distance is then au- tomatically set to a distance which is slightly less than the clearance between the sensor and the background. The sensor is thus activated whenever an object is located between the background and the sensor. Sensor Teach-in distance Object...
