[. . . ] For the 2-point window evaluation mode, two switching points must be set. Teaching the switching points in the normal mode The sensor is set at the factory for both outputs to BGS, light on. Place the target object in front of the sensor at the desired position. Teach the switching point for output 1: · Beginning with the key, press it simultaneously with the ENTER key. Threshold level is obtained and the output/ LED is updated. point B Enter in m with / Output 1 Switch. point B set Setting of Switching point C Output 2 2. ) 0 . . . 2. 5 m in 1 cm increments Ad-C Enter Set Switch. point C Enter in m with / Output 2 Switch. point C set Setting of Switching point D 1. ) Output 2 2. ) 0 . . . 2. 5 m in 1 cm increments Ad-d Enter 2 s Enter Set Switch. point D Enter in m with / Output 2 Switch. point D set 5Et 1. ) In the 2-point window evaluation mode, two switching points (A/B and C/D) can be set for each output. In the foreground and background suppression modes, only one switching point (A and C) can be set for each output. Then, only these switching points, A and C, can be set in the TEACH menu path. B and D switching points are not available. 2. ) If connector pin 2 is set as an input, only the switching points for Output 1 can be set.

A second switching output is not available. [. . . ] If this should not be possible, the reflecting surface should not be parallel to the sensor's optical axis, but should be rotated by at least 10°. Mirror-like objects can cause malfunction inside and outside the sensing range. Avoid mirror-like objects in or close to the optical axis. Inspection and Maintenance Cleaning Do not use any scratching or abrasive cleaning materials. The protective pane of the optical system might get damaged. [. . . ]
