Make sure to test the operation of the F3SJ-B after installation to verify that the F3SJ-B operates
as intended. Make sure to stop the machine until the test is complete. Unintended function
settings may cause a person to go undetected, resulting in serious injury.
Make sure to install the F3SJ-B at the safe distance from the hazardous part of the equipment.
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 a
person that passes 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 zones,
eliminating areas where the sensors do not reach. If a person is able step into the hazardous
zone of a machine and remain behind the F3SJ-B's detection zone, configure the system with an
interlock function that prevents the machine from being restarted. Failure to do so may result in
serious injury.
Install the interlock reset switch in a location that provides a clear view of the entire hazardous
zone and where it cannot be activated from within the hazardous zone.
Introduction
The F3SJ-B cannot protect a person from a projectile exiting the hazardous zone. Install
protective cover(s) or fence(s).
Install the F3SJ-B so that it is not affected by a reflective surface. Failure to do so may hinder
detection, resulting in serious injury. Details on installation distance from the reflective surface,
see "Distance from Reflective Surfaces" on page 23.
When using more than one set of F3SJ-Bs, 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-B is securely mounted and its cables and connectors are properly
secured.
Do not use the sensor system with mirrors in a retro-reflective configuration as shown below.
Doing so may hinder detection. It is possible to use mirrors to "bend" the detection zone to a 90degree angle.

Introduction
Perform an inspection for all F3SJ-B as described in "Chapter 5 Checklists".
For wiring
Connect the load between the output and +24 V line (NPN output). Connecting the load between
the output and 0 V line will result in a dangerous condition because operation is reversed to "ON
when blocked".
Do not short-circuit the output line to the 0 V line. Otherwise, the output is always ON. Also, the
+24 V of the power supply must be grounded so that output does not turn ON due to grounding
of the output line.
Configure the system by using the optimal number of safety outputs that satisfy the requirements
of the necessary safety category.
Do not connect each line of F3SJ-B to a DC power supply of more than 24 VDC+20%. Also, do
not connect to an AC power supply. Failure to do so may result in electric shock or breakdown of
the device.
Make sure to perform wiring while the power supply is OFF.
Do not use the auxiliary output for safety applications. Human body may not be detected when
F3SJ-B fails, resulting in serious injury.
For the F3SJ-B to comply with IEC 61496-1 and UL 508, the DC power supply unit must satisfy
all of the following conditions:
• Must be within the rated power voltage (24 VDC
± 20%)
• Must have tolerance against the total rated current of devices if it is connected to multiple
devices
• Must comply with EMC directives (industrial environment)
• Double or reinforced insulation must be applied between the primary and secondary circuits
• Automatic recovery of overcurrent protection characteristics
• Output holding time must be 20 ms or longer
• Must satisfy output characteristic requirements for class 2 circuit or limited voltage current circuit
defined by UL 508. Refer to p.65 for details.
• Must comply with laws and regulations, regarding EMC and electrical equipment safety, of the
country or region where the F3SJ-B is used (Ex: In EU, the power supply must comply with the
EMC Directive and the Low Voltage Directive.)
vi
Double or reinforced insulation from hazardous voltage must be applied to all input and output
lines. Failure to do so may result in electric shock.
Extension of the cable must be within a specified length. If it isn't, safety function may not work
properly, resulting in danger.
F3SJ-B

Other
To use the F3SJ-B in PSDI mode (Reinitiation of cyclic operation by the protective equipment),
you must configure an appropriate circuit between the F3SJ-B and the machine. For details
about PSDI, refer to OSHA1910.217, IEC 61496-1, and other relevant standards and
regulations.
Do not try to disassemble, repair, or modify this product. Doing so may cause the safety functions
to stop working properly.
Do not use the F3SJ-B in environments where flammable or explosive gases are present. Doing
so may result in explosion.
Perform daily and 6-month inspections for the F3SJ-B. Otherwise, the system may fail to work
properly, resulting in serious injury.

Self-test Function
The F3SJ-B performs the self-test when power is turned ON (within 2 seconds) to check for errors.
Also, it regularly performs the self-test (within a response time) while operating.
This function cannot be cancelled.
If an error is found in the self-test, the F3SJ-B enters lockout state, keeps the safety output in the OFF
state, and indicates the error at the same time.
Self-test details
The self-test detects the types of errors described below.
Emitter
• Failure of emitter element or circuit
• CPU failure
• Disconnected or short-circuited cable
Receiver
• Abnormal external power supply voltage
• Failure of internal power supply circuit
• Failure of receiver element or detection circuit
• CPU failure
• Memory failure
• Incidence of disturbance light
• Failure of safety output circuit
• Disconnected or short-circuited cable
Chapter2 Description of Functions
Waveform of safety outputs
When the F3SJ-B is receiving light, the safety outputs cyclically turn OFF as shown below to test the
output circuit. When this OFF signal is fed back, the output circuit is diagnosed as normal. If the output
signal does not include an OFF pulse signal due to short-circuit, etc, the receiver diagnoses a failure in
the output circuit or wiring, and it enters lockout state.
