System Operation and Functions
3.
Muting state is maintained (Muting sensor A1: OFF)
The workpiece has completely passed the muting sensor A1 and the sensor is now in the OFF state. In
the Standard Muting mode, the Muting state is released here. In the Exit-Only Muting mode, the F3SG-
SR's safety function is disabled for the exit-only muting delay time: T5.
4.
Muting state is maintained (Muting sensor B1: OFF)
The workpiece has completely passed the muting sensor B1 and the sensor is turned OFF. The F3SG-
SR disables its safety function if it is within the exit-only muting delay time.
5.
The workpiece passed the F3SG-SR's detection zone
A workpiece has passed the F3SG-SR's detection zone. When the muting end wait time: T4 (1 s:
configurable) passes after the F3SG-SR is unblocked, the MUTING state is released.
 Installation distande
Distances between the muting sensors A1, B1, and the F3SG-SR must be configured based on speed
of a workpiece.
Distance d1 between the muting sensors A1 and B1 must satisfy Equations (1) and (2).
Distance d2 between the muting sensor A1 and F3SG-SR must satisfy Equations (3) and (4).
Time t1 [ s ] to turn the muting sensors A1 and B1 in this order is:
t1 = d1 / VEquation (1)d1 [ m ] : Distance between muting sensors A1 and B1
V [ m/s ] : Approach speed of a workpiece
Time t1 in Equation (1) for F3SG-SR to enter MUTING state is within a range shown below:
T1min < t1 < T1maxEquation (2)T1min [ s ] : Muting input time limit value (minimum)
T1max [ s ] : Muting input time limit value (maximum)
