Turn ON the sensor to perform beam alignment.
Move the emitter from side to side (Figure 3) to align it to a center position where the stable-state
indicator (STB) is turned ON while checking the top beam state and bottom beam state with the top-
beam-state indicator (TOP) and bottom-beam-state indicator (BTM). (Figure 4)
Next, move the receiver from side to side (Figure 3) to align it to a center position where the stable-
state indicator (STB) is turned ON. (Figure 4)

- Confirm that there is no interrupting object in the detection zone before adjusting beams.
- If the stable-state indicator (STB) does not turn ON despite performing alignment, check if the mounting surfaces of
the emitter/receiver are parallel, and if the mounting height of the emitter/receiver is appropriate. Using optional
Laser Alignment Kit (F39-PTJ) makes alignment easier.
