•T3: Muting input time with allowable waveform cracks
This is the maximum value for the waveform cracks allowed for muting input 1 and 2 when muting is
in effect. It is set to 0.1 sec.
 Installation Example 2 of Standard Muting Mode (using 4
muting sensors)
This installation example uses 4 through-beam type photoelectric sensors as muting sensors.
The use of 4 muting sensors is useful when the length of the workpieces (L) is constant or longer.
1. Before a workpiece passes through
All muting sensors are turned OFF and the safety function of the F3SJ is working.
2. The muting sensors are blocked and the safety function of the F3SJ is disabled
When muting sensors A1 and B1 are turned ON in this order, the muting function is enabled. In this
state, the safety function of F3SJ is disabled.
