System Operation and Functions
 Installation example 1 of standard muting mode (Using two muting sensors)
This is an example of two retro-reflective type photoelectric sensors used as muting sensors installed
in a cross pattern.
Use two sensors when the length L of the workpieces are not constant or are insufficient.
1. Before a workpiece passes through
The output state of muting sensors A1 and B1 are both OFF, and the safety function of the F3SG-RA is
working.
In this example where two muting sensors are used, the crossover point of muting sensors A1 and B1
is in the hazardous zone. This configuration prevents the muting function from being enabled by a
person passing through the crossover point.
2. Muting state started
When muting sensors A1 and B1 are turned ON in this order, the F3SG-R enters the muting state. In
this state, the safety function of F3SG-RA is disabled.
