6 Commissioning
1 Alignment
Figure 2: Alignment
2 Sensing range
Adjust the distance between the sensor and the reflector according to the corresponding
diagram [see figure 3] (x = sensing range, y = operating reserve).
After alignment is complete, move a non-transparent object into the path of the beam. Use
table 1 to check the function. If the switching output fails to behave in accordance with
table 1, check the application conditions.
