Muting Function
Summary
Makes settings related to the muting function.
The muting function disables the safety functions of the device.
Additional safety measures must be taken to ensure safety while this
function is working.
Install muting sensors so that they can distinguish between the object
that is being allowed to be pass through the detection zone and a
person.
Muting lamps (external indicators) that indicate the status of the
muting function must be installed where they are clearly visible to
workers from all the operating positions.
Muting times must be precisely set according to the application by
qualified personnel who have received appropriate training. In
particular, if the muting time limit is to be set to infinity, the person who
makes the setting must bear responsibility.
Use two independent input devices for the muting inputs. (For the
PNP output-type F3SJ, use a sensor with a PNP transistor output or
N.O. contact. For the NPN output-type F3SJ, use a sensor with an
NPN transistor output or N.O. type contact.)
To prevent a worker from entering the hazardous area while the
muting function is engaged, install the F3SJ, muting sensor, and then
a protective barrier and set a limited muting time.

Example Applications
Description of Functions (See User's Manual for details.)
Operation Modes
When the SD Manager Setting Support Software is being used, any
one of the following three operation modes can be selected for the
muting function.
1. Standard Muting Mode
Note: Settings such as the muting time limit value can be changed.
2. Specialized Exit Muting Mode (Can be set with the SD Manager
3. Position Detection Muting Mode (Can be set with the SD Manager
Partial Muting (Muting area) Settings
The light beams controlled by the muting function can be specified
with a setting tool. (When the F3SJ is shipped, all light beams are set.)
The light beams can be specified by teaching/recording the blocked
light beams as muting light beams or manually specifying the desired
light beams.
• Allowing only work pieces to pass into the conveyor entrance
• Operating the muting function in a specific area only
• Setting a different muting mode when standard muting is not
appropriate for the application
This is the default operation mode, which is set when the F3SJ is
shipped from the factory.
The muting function is enabled by turning ON muting inputs 1 and
2 with a time lag.
Setting Support Software only.)
The muting function is enabled by turning ON muting inputs 1 and
2 with a time lag.
Installation of the muting input sensors is simpler than standard
mode because the Safety Light Curtain's blocked light status is
used to end muting.
Setting Support Software only.)
Sensors such as limit switches are used for the muting inputs and
the muting function is enabled by turning muting input from OFF to
ON and then turning muting input 2 from ON to OFF within time
difference T1 max. Use hybrid redundant inputs such as a
combination of an N.O. contact input and an N.C. contact input.
(When using a PNP-output photoelectric switch, use L/ON
operation on one side and D/ON operation on the other side.)
This mode is useful when you want to disable the F3SJ
temporarily, such as when a person is placing an object at the
conveyor entrance.
