ADJUSTMENT Section 

 

3-1 Adjustment Procedure 

 
1. Ensure the following points. 

• 

A hazardous part of a machine cannot move during the adjustment. 

• 

The optical surfaces of the emitter and receiver are clean. 

• 

There should be no light-interrupting objects in the F3S-B detection zone. 

2. Adjust the torsion angle of the emitter while monitoring the indicator on the receiver and locate the point 

where the ON-state indicator (lit: green) is lit and the Instability indicator (UNSTAB: orange) goes OFF. 

3. Adjust the torsion angle so that the light-receiving condition becomes as stable as possible.  When the 

above adjustments have been completed, tighten all brackets and mounting screws while being careful 
not to change the optical axis adjustment for the F3S-B. The tightening torque for these screws is shown 
in the following table.

4.3 N·m (43.9 kg·cm) 

 

4. If a stable light receiving condition is not obtained through the angle adjustment of the emitter, perform the 

following adjustments. 

If the Instability indicator does not go OFF, temporarily fix the emitter at the most stable state and 
conduct angle adjustment for the receiver according to the procedure described in the above step 2. 

5. If a stable light receiving condition is not obtained 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. 

 

3-2 Check List 

 

Check the following items to make sure the installation is correct

 

 

1. 

%

  Machine structure does not hinder stop and other safety functions. 

2. 

%

  Intrusion into a hazardous part of the machine is not possible without passing through the F3S-B de-

tection zone. 

3. 

%

  Protective structure that allows the F3S-B to detect an operator when he/she works in the hazardous 

area. 

4. 

%

  The actual safety distance is greater than the calculated distance. 

5. 

%

  Reflective surfaces are not installed in prohibited areas. 

 

Check the following items to make sure wiring is correct before turning ON power.

 

 
  1. 

%

  The power supply is connected only to the F3S-B and to the devices related to the electro-sensitive 

protective function of the F3S-B, such as a safety controller and muting sensors, and it has enough 
rated current for all the devices.  

  2. 

%

  The power supply unit is a 24-VDC unit that conforms to the EMC Directive, Low-voltage Directive 

and output holding specifications. 

  3. 

%

  The polarity of the power supply connection is not reversed. 

  4. 

%

  The emitter extension cable is properly connected to the emitter and the receiver extension cable is 

properly connected to the receiver. 

  5. 

%

  Double insulation or reinforced insulation is used between the output and the hazard potential 

(commercial power supplies, etc.), and between the Relay monitoring input and the hazard potential. 

  6. 

%

  Outputs are not shorted to the +24V line. 

  7. 

%

  Loads are not connected to the +24V line. 

  8. 

%

  No lines are connected to a commercial power supply.
