4-4-4. Beam Alignment Procedure
The Free-Location Bracket and Top/Bottom Bracket allow beam alignment after fixing the bracket to a wall surface.
1.
Verify the following points:
- The optical surfaces of the emitter and receiver are clean.
- There is no interrupting object in the detection zone of the F3SG-R.
2.
Align the beams of the emitter and receiver:
Move the emitter and receiver from side to side to align each of these to the center position where the
Stable-state indicator (STB, green) of the receiver is illuminated while checking the state of the top and
bottom beams with the Top-beam-state indicator (TOP, blue) and Bottom-beam-state indicator (BTM,
blue) of the receiver.
Perform beam alignment to the primary sensor first, when using the F3SG-R in a cascade conection.
3.
Verify that all the three indicators of the receiver, Top-beam-state (TOP, blue), Bottom-beam-state
(BTM, blue) and Stable-state (STB, green) indicators are illuminated.
4.
Make sure to keep the beams aligned and tightly fasten all screws.
The table below shows the recommended tightening torques for the included screws.
- If any of the Top-beam-state (TOP, blue), Bottom-beam-state (BTM, blue) and Stable-state (STB, green) indicators are
not illuminated, check if the emitter and receiver are mounted parallel and at the same height.
- Tightening screws with a torque that considerably exceeds the recommended torque may cause failure.
- It is recommended to use the Light Level Monitoring with the Configuration Tool for beam alignment. Refer to
Safety
