2-4-4 Adjustment Procedures
[Procedures]
1. Ensure the following points.
• The optical surfaces of the emitter and receiver are clean.
• There should be no light-interrupting objects in the F3SN-A detection zone.
2. Adjust the beams of the emitter.
Adjust the torsion angle of the emitter while monitoring the light intensity level indicators and locate the
emitter in the point where the light intensity level indicators are lit.
3. Adjust the receiver.
Adjust the torsion angle of the receiver while monitoring the light intensity level indicators and locate the
receiver in the point where the light intensity level indicators are lit.
4. Confirm all the light intensity level indicators are lit.
5. When the above adjustments have been completed, tighten all brackets and mounting screws while being
careful not to change the beam adjustment for the light curtain.
6. If all of the light intensity level indicators are not lit through the above angle adjustment of the receiver,
check for parallelism between the emitter mounting surface and the receiver mounting surface and also
check if the emitter and receiver are mounted to the same height.
A person in charge should check the following check boxes.

5.
Machine structure does not hinder stop and other safety functions.
Intrusion into a hazardous part of the machine is not possible without passing through the F3SN-A
Protective structure allows the F3SN-A to detect an operator when he/she works in the hazardous area.
The switch to reset the interlock condition has to be installed so that the entire hazardous area is visibly
The safety distance has been calculated. Calculated distance: S = (
The actual safety distance is greater than the calculated distance. Actual distance = (
Reflective surfaces are not installed in prohibited areas.
The power supply is connected only to the F3SN-A and to the devices related to the electro-sensitive
The power supply unit is a 24 VDC unit that conforms to the EMC Directive, Low-voltage Directive, and
The polarity of the power supply connection is not reversed.
The emitter cable is properly connected to the emitter and the receiver cable is properly connected to
Double insulation is used between I/O lines and the hazard potential (commercial power supplies, etc.).
