User’s Manual
System Configuration and Functions
3. The muting sensors are blocked and the safety function of the F3SJ is disabled
Muting sensors A1 and B1 are turned OFF but A2 and B2 are ON, so the muting function is still
working. Safety outputs 1 and 2 are turned ON.
4. The muting function is released
Muting sensor A2 is turned OFF and the muting function is released, and the safety function of the
F3SJ is working.
Installation Distance
The minimum distances, D2 [ m ] and D3 [ m ], required for the muting sensors to keep the muting
function enabled are
D2
< L . . . . . Formula (3)
D3
< L . . . . . Formula (4)
L [ m ] : Length of a workpiece
The maximum distance, d2 [ m ], required for muting sensors to keep the muting function enabled is
V x T1min
< d2 < V x T1max . . . . . Formula (5)
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.
To enable the muting function, D2, D3, and d2 must satisfy formulas (3), (4), and (5), respectively.
