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.

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.
