A workpiece passed F3SJ's detection zone
A1 : Muting sensor to be connected
to muting input 1
B1 : Muting sensor to be connected
to muting input 2
A workpiece passed F3SJ's detection zone. When muting end waiting time: T4 (0.1s) passed after
F3SJ received light, muting state is released.
• Installation Distance
Distances between muting sensors A1, B1, and F3SJ must be configured based on speed of a
workpiece.
Distance d1 between muting sensors A1 and B1 must satisfy Equations (1) and (2).
Distance d2 between muting sensor A1 and F3SJ must satisfy Equations (3) and (4).
Time t1 [ s ] to turn muting sensors A1 and B1 in this order is:
t1 = d1 / V . . . . . . . . . . . Equation (1)
Time t1 in Equation (1) for F3SJ to enter muting state is within a range shown below:
T1min < t1 < T1max. . . . Equation (2)
The PC tool for F3SJ can change T1min and T1max.
Time t2 [ s ] for a workpiece to pass F3SJ's detection zone after passing the muting sensor A1 is:
t2 = d2 / V . . . . . . . . . . . Equation (3)
Time t2 in Equation (3) must satisfy following condition:
t2 < T5 . . . . . . . . . . . . . . Equation (4)
The PC tool for F3SJ can change T5.
Sensors must be installed so that person's passing should not cause muting state.
