4.
The muting state is released
Muting sensor A1 is turned OFF, the muting state is released, and the safety function of the F3SG-RA
is enabled.
<Installation distance>
The minimum distance, D1 [m], required for muting sensors to keep the muting state 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 state 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). It is set as 0.1 s.
T1max [s]: Muting input time limit value (maximum). It is set as 4 s.
To enable the muting state, D1 and d1 must satisfy formulas (1) and (2), respectively.
