User’s Manual
System Configuration and Functions
To enable the muting function, D1 and d1 must satisfy formulas (1) and (2), respectively.
This distance must prevent the muting function from being enabled by a person passing through the
muting sensors.
Also, install the F3SJ-B and muting sensors so that each workpiece passes through all muting sensors
before the next workpiece arrives at the first muting sensor.

Variable Variable name Value Description
T1min
Muting input time limit value
(minimum)
0.1 s
Minimum time difference between muting inputs 1 and 2.
If the time difference between muting inputs 1 and 2 is smaller
than this value, a muting error occurs.
T1max
Muting input time limit value
(maximum)
3 s
Maximum time difference between muting inputs 1 and 2.
If the time difference between muting inputs 1 and 2 is larger than
this value, a muting error occurs.
T2 Muting time limit 60 s
This is the muting function continuation time.
If muting state exceeds this time, the function is canceled.
T3
Maximum muting input pulse
duration
0.1 s
Maximum muting input time with allowable waveform cracks in
muting input 1 and 2.
