Wiring/Installation
No Connection
Mutual interference is prevented in up to 3 sets, using interference light avoidance algorithm. If 4 or
more sets of F3SJ are installed and are not connected to each other, arrange them so that mutual
interference does not occur. If 2 sets are installed near each other, reflection from the surface of the
F3SJ may cause mutual interference. When mutual interference occurs, the safety outputs are turned
OFF in a moment or the F3SJ enters lockout.
Combining countermeasures 1 to 4 shown below is effective.
1. Install a physical barrier between 2 sets
2. Alternate the direction of emission between 2 sets (alternation)
If 2 sets are installed near each other, reflection from the surfaces may cause mutual interference.
For such a case, it can be improved by reducing operating range through the setting tool (see Step 3).
3. Reducing operating range (setting change by the setting tool is required)
