Installation example 2 of standard muting mode (Using four muting sensors)
This installation example uses four through-beam type photoelectric sensors as muting sensors.
The use of four muting sensors is useful when the length of the workpieces is constant or longer, and
the entrance and exit have enough space. Muting can be performed from both directions in the
arrangement as shown below.
1.
Before a workpiece passes through
All muting sensors are turned OFF and the safety function of the F3SG-RA is working.
2.
The muting sensor is blocked and the safety function of the F3SG-RA is disabled
When muting sensors A1 and B1 are turned ON in this order, the muting state is enabled. In this state,
the safety function of F3SG-RA is disabled.
