Description
Position Detection muting function
Position Detection
Muting Function is
used in applications
where the workpiece
is set in position
each time by an
operator, and a
turntable or position-
ing robot then moves
the workpiece to the
area where the work
is performed. A limit switch or other means is used to detect when
the robot is in a safe position and muting is then applied.
Warning Zone function
With the F3SJ-A, part of the detection zone can be used as
warning zone to generate an alarm when someone approaches
the danger zone. If the person then enters the danger zone the
F3SJ-A will send a stop signal to the guarded machine. In addi-
tion, the auxiliary output can be used to activate a flashing lamp
to alert the person in the warning zone.
The detection zone for a single F3SJ-A can be divided into two
zones or set a single warning zone for multiple, cascaded F3SJ-A
units.
Dividing the zone between series-connected sensors
Detection zone
Partial muting function
Muting temporarily disables the F3SJ-A when an object must
pass through the detection zone, such as when supplying a
workpiece to your equipment.
The F3SJ-A beams
Partial muting

increases the level of
areas except for where
safety by only muting
the workpiece passes
through.
the beams of the
safety light curtain
where the workpiece
passes through, while
preventing muting in
all other areas.
Warning zone
Only the beams of the safety
light curtain interrupted by
the workpiece are muted.

SD manager Software
Using the SD Manager software, all
features of the F3SJ-A can be set and
checked. Features include:
• Display of system specifications:
– Model
– Number of beams
– Minimum object resolution
– Response time
• Settings for:
– Fixed blanking
– Floating blanking
– Warning zone configuration
– Muting – Both partial and position
detection
– External indicator function
– Auxiliary outputs
– EDM parameters
– Operating range
• Monitoring of received and ambient
light intensity
• Maintenance information:
– Power on time
– OSSD switching frequency
• Recovery of settings
• Safety distance calculations based on
parameters for connected system
Setting console
When you don’t want to take a computer into
the field with you the F39-MC21 setting console
is a convenient way to set parameters and
check the system status.

All parameters can be set and the system status can be checked
with a personal computer. In addition to making it easy to monitor
the beam alignment, the ambient incident light intensity can be
displayed in bar graph form for an easy check of the system status.

Applications
With built-in muting and
blanking functions, the F3SJ-A
can be employed in a wide
variety of applications from
robotic work cells to small
machines. The potential
for cascaded design and a
broad selection of minimum
object resolutions adds to this
versatility.
The incident light level when the light emission of the
Safety Light Curtain is stopped is displayed in a bar
graph.
Selecting the Best configuration
Space efficient and low cost
The built-in external device monitoring function
eliminates the need for a safety relay unit.
