<Reference: Preventing light interference of muting sensor>
When a photoelectric sensor is used as a muting sensor, light interference may cause a muting error of
F3SJ-B.
The cause and measures for light interference are shown as follows:

Value
Minimum time difference between muting inputs 1 and 2.
0.1 s If the time difference between muting inputs 1 and 2 is smaller
than this value, a muting error occurs.
Maximum time difference between muting inputs 1 and 2.
3 s If the time difference between muting inputs 1 and 2 is larger than
this value, a muting error occurs.
This is the muting function continuation time.
60 s
If muting state exceeds this time, the function is canceled.
Maximum muting input time with allowable waveform cracks in
