maintenance.

For machines

iv

Do not use this sensor for machines that cannot be stopped by electrical control. For example,
do not use it for a pressing machine that uses full-rotation clutch. Otherwise, the machine may
not stop before a person reaches the hazardous part, resulting in serious injury.

F3SJ-E/B

User’s Manual

For installation

Reflector

Position with retro-reflection

Position with detection zone bent at 90°

Reflector

Make sure to test the operation of the F3SJ-E/B after installation to verify that the F3SJ-E/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-E/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-E/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-E/B cannot protect a person from a projectile exiting the hazardous zone. Install
protective cover(s) or fence(s).

Install the F3SJ-E/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 41.

When using more than one set of F3SJ-E/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-E/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.

F3SJ-E/B

User’s Manual

E

v

Introduction

Perform an inspection for all F3SJ-E/B as described in "Chapter 5 Checklists".

Install muting sensors so that they can distinguish between the object that is being allowed to be
passed 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.

Use independent two input devices for muting inputs.

The muting and override functions disable the safety functions of the device. You must ensure
safety using other method when these functions are operating.

Install the switch that uses hold-to-run device such as a spring-return key switch and is installed
in a location that provides a clear view of the entire hazardous zone and where it cannot be
activated from within the hazardous zone. Make sure that nobody is in the hazardous zone
before activating the override function.

For wiring

Connect the load between the output and 0 V line (PNP output). Connecting the load between
the output and +24 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 +24 V line. Otherwise, the output is always ON. Also,
the 0 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-E/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.
