For mounting
Make sure to test the operation of the F3SJ after installation to verify
that the F3SJ operates as intended. Do not operate the machine until
the test has been completed and F3SJ operation has been verified.
Unintended function settings may cause a person to go undetected,
resulting in serious injury.
Make sure to secure the safety distance between the F3SJ and the
hazardous parts. Otherwise, the machine may not stop before a
person reaches the hazardous part, resulting in serious injury.
Install a protective structure so that the hazardous part of a machine
can only be reached by passing through the sensor's detection zone.
Install the sensors so that part of the person is always present in the
detection zone when working in a machine's hazardous areas. If a
person is able to step into the hazardous area of a machine and
remain behind the F3SJ's detection zone, configure the system with
an interlock function that prevents the machine from being restarted.
Otherwise it may result in heavy injury.
Install the interlock reset switch in a location that provides a clear view
of the entire hazardous area and where it cannot be activated from
within the hazardous area.
The F3SJ cannot protect a person from an object flying from a
hazardous area. Install protective cover(s) or fence(s).
When detection of an area has been disabled by the fixed blanking
function, provide a protective structure around the entire area that will
prevent a person from passing through it and reaching the hazardous
part of the machinery. Failure to do so may prevent detection of
people and result in serious injury.
After setting the fixed blanking function, be sure to confirm that a test
rod is detected within all areas that require detection. Failure to do so
may prevent detection of people and result in serious injury.
When the fixed blanking function or the floating blanking function is
used, the diameter for the smallest detectable object becomes larger.
Be sure to use the diameter for the smallest detectable object for the
fixed blanking function or the floating blanking function when
calculating the safety distance. Failure to do so may prevent the
machinery from stopping before a person reaches the hazardous part
of the machinery, and result in serious injury.
The muting and override functions disable the safety functions of the
device. Additional safety measures must be taken to ensure safety
while these functions are 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. If the muting function is activated by the detection of a person,
it may result in serious injury.
Muting lamps (external indicators) that indicate the state of the muting
and override functions 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.
Install the F3SJ, Muting Sensors, or a protective wall so that workers
cannot enter hazardous areas while muting is in effect, and set muting
times.
Position the switch that is used to activate the override function in a
location where the entire hazardous area can be seen, and where the
switch cannot be operated from inside the hazardous area. Make sure
that nobody is in the hazardous area before activating the override
function.
Install the sensor system so that it is not affected by reflective
surfaces. Failure to do so may hinder detection, resulting in serious
injury.
!WARNING
When using more than 1 set of F3SJ, install them so that mutual
interference does not occur, such as by configuring series
connections or using physical barriers between adjacent sets.
Make sure that the F3SJ is securely mounted and its cables and
connectors are properly connected.
Make sure that no foreign material, such as water, oil or dust, enters
the inside of the F3SJ while the cap is removed.
Do not use the sensor system with mirrors in as retro-reflective
configuration. Doing so may hinder detection. It is possible to use
mirrors to "bend" the detection zone to a 90-degree angle.
When using series connections, perform inspection of all connected
F3SJs as instructed in the User's Manual.
For wiring
For PNP output, connect the load between the output and 0 V line.
For NPN output, connect the load between the output and +24 V line.
Connecting the load between the +24 V and 0 V lines results in a
dangerous condition because the operation mode is reversed to "ON
when light is interrupted".
[For PNP output]
Do not short-circuit an output line to +24 V line. Otherwise, the output
is always ON, creating a dangerous situation. Also, 0 V of the power
supply must be grounded so that output should not turn ON due to
grounding of the output line.
[For NPN output]
Do not short-circuit an output line to 0 V line. Otherwise, the output is
always ON, creating a dangerous situation. Also, the +24 V line of the
power supply must be grounded so that output does not turn ON due
to grounding of the output line.
