Wiring/Installation
6.
Turn ON the sensor to perform beam alignment.
Move the emitter from side to side (Figure 21) 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 22)
Next, move the receiver from side to side (Figure 21) to align it to a center position where the stable-
state indicator (STB) is turned ON. (Figure 22)
- 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.
7.
Tighten the lightly tightened the hexagon socket head cap screws (M3 x 18) of Intermediate Bracket (3)
to prevent rotation. (Figure 23)
If there are three or more Intermediate Brackets, tighten the hexagon socket head cap screws (M3 x
18) from the order of top, bottom and middle brackets with a tightening torque at 0.54 N•m
(recommended).
Tightening screws with a torque that considerably exceeds the recommended torque may cause failure.
Mounting is complete.
