The muting function is released
Muting sensor A1 is turned OFF, the muting function is released, and the safety function of the F3SJ is
enabled.
 Installation Distance
The minimum distance, D1 [ m ], required for muting sensors to keep the muting function enabled is
D1
<
L . . . . . Formula (1)
L [ m ] : Length of a workpiece
The maximum distance, d1 [ m ], required for muting sensors to keep the muting function enabled is
V x T1min
<
d1
<
V x T1max . . . . . Formula (2)
V [ m/s ] : Approach speed of a workpiece
T1min [ s ] : Muting input time limit value (minimum). 0.03s.
T1max [ s ] : Muting input time limit value (maximum). 3s.
Use the PC tool for F3SJ to change following values:
•T1min: Muting input time limit value (minimum)
•T1max: Muting input time limit value (maximum)
Muting function p.90
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 and muting sensors so that a workpiece passes through all muting sensors
before the next workpiece arrives at the muting sensors.
