Beam Alignment Procedure - Omron F3SG-PGA-A User Manual

5-3-5. Beam Alignment Procedure

The Adjustable Side-Mount Bracket (Intermediate Bracket) (F39-LSGA) and Adjustable Top/Bottom Bracket (F3SJ, F3SN
Adapter) (F39-LSGTB-SJ) allow beam alignment after fixing the brackets to a wall surface. The Side-Mount Bracket
(Intermediate Bracket) (F39-LSGF) does not allow beam alignment.
1.
Verify the following points:
- The optical surface of the sensor is clean.
- There is no interrupting object in the detection zone of the sensor.
2.
Align the beams of the sensor.
Move the emitter and receiver, the emitter/receiver, and the passive mirror, from side to side to check
the state of the beams with the ABI indicators or the TOP and BTM indicators. When the stable
unblocked state is established, the TOP and BTM indicators turns blue and the ABI indicators change
the color at every second from green -> orange -> green -> orange -> green, indicating that the beam
alignment is complete.
Adjust the angle of the sensor to bring the beams in the stable unblocked state.
1-4. LED Indicators on F3SG-SR/PG
- The ABI indicators are for F3SG-SRA and F3SG-PG. The TOP and BTM indicators are for the F3SG-SRB only.
- The ABI indicators of the emitter are illuminated only in the case the Wired Synchronization is enabled and are off in
the case the Optical Synchronization is enabled.
- Perform beam alignment to the primary sensor first, when using the F3SG-SR in a cascade connection.
- It is recommended to use the Light Level Monitoring with the SD Manager 3 for beam alignment. Refer to Chapter 4
Setting with SD Manager 3 for more information.
- The ABI indicators (green) will not be illuminated if the blanking function is used and there is a blocking object in the
detection zone. Perform beam alignment again to illuminate the ABI indicators (green) after setting the blanking
function.
- If any of the ABI indicators (green) or either TOP or BTM indicator is not illuminated, check if the emitter and receiver
are mounted parallel and at the same height.
3.
When the Start Interlock is disabled, the safety outputs are turned to the ON state simultaneously with
the establishment of the stable unblocked state. Confirm that the ABI indicators are illuminated in
green and the TOP and BTM indicators are illuminated in blue when the safety outputs are in the ON
state.
When the Start Interlock is enabled, the ABI or TOP/BTM indicators are turned off simultaneously with
the establishment of the stable unblocked state. Confirm that the ABI indicators are illuminated in
green and TOP and BTM indicators are illuminated in blue when the Start Interlock is released (and the
safety outputs are in the ON state) by turning the RESET input in the ON state.
