System Configuration and Functions
3. The muting sensor is blocked and the safety function of the F3SJ-B 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 B2 is turned OFF, the muting function is released, and the safety function of the F3SJ-B
is enabled.
<Installation distance>
The minimum distance, D3 [m], required for muting sensors to keep the muting function enabled is :
D3 < L . . . . . Formula (3)
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 (4)
V [m/s] : Approach speed of a workpiece
T1min [s] : Muting input time limit value (minimum). It is set as 0.1 s.
T1max [s] : Muting input time limit value (maximum). It is set as 3 s.
