Sensing range

Adjust the distance between the sensor and the reflector according to the correspond‐
ing diagram [figure 10] (x = sensing range, y = operating reserve).
After alignment, place a non-transparent object into the path of the beam. Check the
function as described in table
table 5, check the application conditions.
