Omron F3SG-SRB Series User Manual page 105

The values of T1 and T1
min
Time t2 [ s ] for a workpiece to pass the F3SG-SR's detection zone after passing the muting sensor A1
is:
t2 = d2 / VEquation (3)d2 [ m ] : Distance between muting sensor A1 and F3SG-SR
V [ m/s ] : Approach speed of a workpiece
Time t2 in Equation (3) must satisfy following condition:
t2 < T5Equation (4)T5: Exit-only muting delay time
The value of T5 can be changed by the SD Manager 3.
Sensors must be installed so that person's passing should not cause the MUTING state.
Also, the muting sensors and F3SG-SR must be installed so that MUTING state caused by a
workpiece should be ended before the next workpiece arrives at the first muting sensor.
