F3SG-SR

User’s Manual

Machines

Do not use this sensor for machines that cannot be stopped quickly 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.

To use the F3SG-SR in PSDI mode (initiation of cyclic operation by a presence sensing device),
you must configure an appropriate circuit between the F3SG-SR and the machine. For details
about PSDI, refer to OSHA 1910.217, IEC 61496-1, and other relevant standards and
regulations.

Installation

Make sure Responsible Person tests the operation of the F3SG-SR and F39-SGIT-IL3 after
installation to verify that the F3SG-SR and F39-SGIT-IL3 operate as intended. Make sure to stop
the machine until the test is complete. Unintended installation, wiring or function settings may
cause a person to go undetected, resulting in serious injury.

Make sure to install the F3SG-SR at the safety distance from the hazardous part of the machine.
Otherwise, the machine may not stop before a person reaches the hazardous part, resulting in
serious injury.

Introduction

Install a protective structure so that the hazardous part of a machine can only be reached by
passing through the sensor's detection zone. If access to the hazardous part by reaching over
the detection zone of a vertically mounted F3SG-SR cannot be excluded, the height of the
detection zone and the safety distance shall be determined in consideration of such a risk. Install
the sensors so that part of the person is always present in the detection zone when working in a
machine's hazardous zones. If a person is able to step into the hazardous zone of a machine
and remain behind the F3SG-SR's detection zone, configure the system with Restart Interlock
function. Failure to do so may result in serious injury due to unexpected startup.

Install the 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.

Install the pre-reset switch always in the hazardous zone and where it cannot be activated from
outside the hazardous zone.

The F3SG-SR cannot protect a person from an object flying from the hazardous zone. Install
protective cover(s) or fence(s).

Install a protective structure to cover the whole blanked zone in order to prevent personnel
approach to hazardous part of the machine through the blanked zone.

Detection capability gets larger when Fixed Blanking, Floating Blanking or Reduced Resolution
function is used. When these functions are used, the safety distance calculation must be based
on the increased detection capability for these functions. Otherwise, the machine may not stop
before a person reaches to the hazardous part, resulting in serious injury.

F3SG-SR

User’s Manual

Introduction

If detection capability may get larger and a human body may pass a detection zone to reach a
hazardous source, additional safety protection equipment must be installed such as a safety
fence.

A warning zone must not be used for safety applications. Always install your system so that a
detection zone should be passed before reaching a hazardous part of the machine. If access to
the hazardous part by reaching over the detection zone of a vertically mounted F3SG-SR cannot
be excluded, the height of the detection zone and the safety distance shall be determined in
consideration of such a risk.

When a warning zone is configured, you must attach labels that indicate a border between
normal detection zone and warning zone. Otherwise, the machine may not stop before a person
reaches to the hazardous part, resulting in serious injury.

A warning zone must be configured based on a safety distance.

The Muting and Override functions disable the safety functions of the device. Especially setting
the Muting Time Limit parameter to infinite may cause the safety functions to be disabled for a
long time. Install the F3SG-SR, muting sensor and physical barrier and configure time settings
for Muting and Override so that an operator should not enter hazardous zone when the Muting
and Override are active.

Install muting sensors so that they can distinguish between the object that is being allowed to
pass through the detection zone and a person. If the Muting function is activated by the detection
of a person, the machine may not stop operating, resulting in serious injury.

Muting lamps 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.

Use two independent input devices for muting inputs. Failure to do so may cause the MUTING
state due to a single muting sensor's failure.

Install the switch that activates the Override and that uses hold-to-run device, such as spring
return key 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. Make sure that nobody is in the
hazardous zone before activating the Override function.

Make sure to connect an override cancel switch to the RESET line when using the Override
function. Otherwise, the OVERRIDE state may not be released by the override cancel switch,
resulting in serious injury.

Install the F3SG-SR so that it is not affected by reflective surfaces. Failure to do so may hinder
detection, resulting in serious injury. For an installation distance from reflective surfaces, see 5-
1-3. Distance from Reflective Surfaces.

viii

When using more than one set of F3SG-SR's in adjacent areas, the emitter of one F3SG-SR
may interfere with the receiver of the other, causing the safety functions to stop working properly.
Install, configure and maintain them so that mutual interference does not occur.

To change the response time, calculate the safety distance based on the setting. Otherwise, the
machine may not stop before a person reaches the hazardous part, resulting in serious injury.

F3SG-SR

User’s Manual

Do not use the F3SG-SR with mirrors in a retro-reflective configuration. Doing so may hinder
detection. It is possible to use mirrors to alter the detection zone to a 90-degree angle.

Wiring

When using the PNP output, connect the load between the output and 0 V line. When using the
NPN output, connect the load between the output and +24 VDC line. Connecting the load
between the output and a different power supply line from the above line will result in a
dangerous condition because the operation mode of safety outputs are reversed to "Dark-ON".

When using the PNP output, do not ground +24 VDC line. When using the NPN output, do not
ground 0 V line. Otherwise, a ground fault may turn the safety outputs ON, resulting in a failure of
stopping the machine.

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 the F3SG-SR to a DC power supply of higher than 24 VDC+20%.
Also, do not connect it to an AC power supply. Failure to do so may result in electric shock.

Make sure to perform wiring while the power supply is OFF.

Do not use the output signal of the auxiliary output or IO-Link output for safety applications.
Failure to do so may result in serious injury when the F3SG-SR fails.

Introduction

For the F3SG-SR to comply with IEC 61496-1 and UL 508, the DC power supply unit must
satisfy
all of the following conditions:

• The DC power supply operates within the rated power voltage (24 VDC ± 20%).

• The DC power supply has tolerance against the total rated current of devices if it is connected
to multiple devices.

• The DC power supply complies with EMC directives (industrial environment).

• Double or reinforced insulation is applied between the primary and secondary circuits.

• The DC power supply has an automatic recovery type of overcurrent protection characteristics.

• Output holding time is 20 ms or longer.

• The DC power supply satisfies output characteristic requirements for class 2 circuit or limited
voltage current circuit defined by UL 508. Refer to 5-4-2. Power Supply Unit.

• The DC power supply complies with laws and regulations, regarding EMC and electrical
equipment safety, of the country or region where the F3SG-SR is used. (For example, in EU,
the power supply must comply with the EMC Directive and the Low Voltage Directive.)

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 functions may not work
properly, resulting in danger.

Settings

Make sure the Responsible Person tests the operation of the F3SG-SR after setting with the DIP
Switch on the F39-SGIT-IL3, Teach-in, SD Manager 3 or End Cap to verify that the F3SG-SR
operates as intended. Make sure to stop the machine until the test is complete. Unintended
settings may cause a person to go undetected, resulting in serious injury.

When performing the Backup, make sure to set the DIP Switch Position 1 at OFF (Unlock) before
turning on the power. If the DIP Switch Position 1 is at ON (Lock), the Restoration is performed,
which may case the settings of the F3SG-SR to be overwritten and a person to go undetected,
resulting in serious injury.

When performing the Restoration, make sure to set the DIP Switch Position 1 at ON (Lock)
before turning on the power. If the DIP Switch Position 1 at OFF (Unlock), the Backup is
performed, which may cause the settings of the Intelligent Tap to be overwritten and a person to
go undetected, resulting in serious injury.

When the Restoration is performed, if the DIP Switch Position 2 is at ON (DIP Switch Enabled)
and settings of the DIP Switch Positions 3 to 8 are different from the backup data in the F39­SGIT-IL3, the settings in the DIP Switch takes priority and are saved in the F3SG-SR. To prevent
such an accident, it is recommended that you set the DIP Switch Position 2 at OFF before
performing the Restoration when you use the settings backed up from the F3SG-SR or make
settings with the SD Manager 3.

When pairing your device with the F39-SGBT Bluetooth® Communication Unit, make sure that
the model name and serial number of the sensor to be configured match the information on your
device.

• Do not install, use, or store the product in the following types of environments:

- Areas with a temperature or humidity out of the specified range

- Areas submerged in water or subject to rain water

• This is a class A product (for industrial environments). In residential areas it may cause radio
interference, in which case the Responsible Person may be required to take adequate measures to
reduce interference.

 Wiring and installation

• Properly perform the wiring after confirming the signal names of all the terminals.

• Do not operate the control system until 3 s or more after turning ON the power of the F3SG-SR.

• When using a commercially available switching regulator power supply, make sure to ground the PE
terminal (protective earth terminal).

• Install the emitter and receiver to the same vertical direction.

• Use brackets of specified quantities and locations according to the dimensions. If the brackets
described above are not used, ratings and performance cannot be met.

• Do not install the F3SG-SR close to a device that generates high-frequency noise. Otherwise, take
sufficient blocking measures.

• Sharing the power supply with other devices may cause the F3SG-SR to be affected by noise or
voltage drop. It is recommended that the F3SG-SR use a power supply dedicated for safety
components, not shared with other devices.

• Do not change the scan code during normal operation. The F3SG-SR transitions to lockout.

• Do not apply load to the connectors.

• The operating range of the safety light curtain attached with the spatter protection cover is 10%
shorter than the rating. Install the product in consideration with the decrease of the operating range.

 Cleaning

• Do not use thinner, benzene, or acetone for cleaning. They affect the product's resin parts and paint
on the housing.

• Use a soft cloth which is dry or wetted with clean water for cleaning. Do not use solvents.

 Object detection

• The F3SG-SR cannot detect transparent and/or translucent objects.

 Settings

• Do not operate the DIP Switch on the F39-SGIT-IL3 during normal operation of the F3SG-SR.
Otherwise, the F3SG-SR enters the LOCKOUT state.

• Do not operate the DIP Switch and Push Switch on the F39-SGIT-IL3 with tools that may damage the
product.

• Be sure that the F3SG-SR is in the SETTING state when making a change to the setting.

1-6-3. Calculation of Response Time of Cascaded Segments

Chapter1 List of Models

F3SG-SRA X F3SG-PG-A/-L ­F3SG-SRB X F3SG-PG-C -

The F3SG-SR can be used in cascade connection. In cascade connection, a response time is
determined by the total number of beams.
If the total number of beams of all F3SG-SR's in a cascade connection is 12 or less, its response time
is 7 ms (Code A)/8 ms (Code B) when the Optical Synchronization is activated and 9 ms or less when
the Wired Synchronization is activated.

2-3. Mutual Interference Prevention

Make sure the Responsible Person tests the operation of the F3SG-SR after setting with the End
Cap to verify that the F3SG-SR operates as intended. Make sure to stop the machine until the test
is complete. Unintended settings may cause a person to go undetected, resulting in serious injury.

When using more than one set of F3SG-SR's in adjacent areas, the emitter of one F3SG-SR
may interfere with the receiver of the other, causing the safety functions to stop working properly.
Install, configure and maintain them so that mutual interference does not occur.

The F3SG-SR has two types of mutual interference prevention methods, the Optical Synchronization and the
Wired Synchronization. When the Optical Synchronization method is used, the F3SG-SR prevents mutual
interference by the Scan Code Selection.

2-3-1. Mutual Interference Prevention of F3SG-SR

Chapter2 Mutual Interference Prevention

2-3-1-1. Optical Synchronization

F3SG-SRA 
F3SG-SRB 

 Overview

Synchronization is required between an emitter and a receiver for normal operation of the F3SG-SR.
The optical synchronization method of F3SG-SR uses a specific beam to realize synchronization. The
beam is hereinafter called "synchronization beam".

By connecting the emitter and receiver with the Intelligent Tap simultaneously, the wired synchronization is configured. If
using the Intelligent Tap and optical synchronization configuration together, do not connect the emitter with the
Intelligent Tap.

Depending on sensor configuration, the synchronization beam is either of the followings:

• One segment system: End beams (Top or Bottom beam)

• Cascaded system : End beams (Top or Bottom beam) of the primary sensor
For an emitter and a receiver to synchronize, at least one synchronization beam must be unblocked.

The synchronization process is performed when:
(1) The power is turned on for an emitter and a receiver
(2) All beams of the primary sensor are blocked and then unblocked
(3) Synchronization is lost due to an error such as noise and ambient light

The sensor can maintain the synchronization in other cases than those described above and it is not necessary to keep

the synchronization beam unblocked all the time.

In the Optical Synchronization, use the same F3SG-SR models for the emitter and receiver.

state.
Response time of “OFF (Not synchronized)  ON” is the response time from when the F3SG-SR is in
the OFF state and the emitter and receiver are not synchronized to when the F3SG-SR is turned to the
ON state. This response time is longer than that of “OFF (Synchronized)  ON” since the F3SG-SR

The F3SG-SR has two scan codes (Code A and Code B). These scan codes have different internal
processing time. The use of different scan codes allows for placement of systems in close proximity
and in line with each other and minimize mutual interference.
The response time for Code A is 1 ms shorter than that for Code B.

Refer to 1-6-1. List of Models and Response Times for more information on the response time at the time of optical

synchronization setting.

Refer to 5-1-4. Mutual Interference Prevention for how to mitigate mutual interference.

SR. The Wired Synchronization for F3SG-SR is realized by wired communication between an emitter
and a receiver. In the Wired Synchronization setting, in up to three sets of the F3SG-SR can prevent
mutual interference.

The Mutual Interference Prevention does not work between the F3SG-SR in the Optical Synchronization and the F3SG­SR in the Wired Synchronization.

Refer to 1-6-1. List of Models and Response Times for more information on the response time.
Refer to 5-1-4. Mutual Interference Prevention for more information on the Mutual Interference Prevention.

There are two ways to operate the F3SG-SR in the Wired Synchronization setting.

1) Connect the emitter and the receiver with the Intelligent Tap.

2) Connect the COM(+) and COM(-) lines of the emitter and receiver with each other.

The COM(+) and MUTE A use the same line and so do the COM(-) and MUTE B. If you use the Muting
and the Wired Synchronization, make sure to connect the F3SG-SR with the Intelligent Tap.

In the Wired Synchronization setting, the Area Beam Indicator (ABI) of the emitter can be linked with
that of the receiver.

In the Optical synchronization, the Area Beam Indicator (ABI) of the emitter keeps off regardless of the operation of the
F3SG-SR.

Refer to 5-4-3-1. Root-Straight Cable for more information on the wiring.

The F3SG-SR in the Wired Synchronization setting also requires the connection with the End Cap. Connect the emitter

and remain behind the F3SG-SR's detection zone, configure the system with Restart Interlock
function. Failure to do so may result in serious injury due to unexpected startup.

Install the 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.

Chapter2 Interlock

2-8-1. Over view

The F3SG-SR turns the safety outputs OFF when its power is turned on or the F3SG-SR is blocked
and holds this state until a RESET signal is received. This state is called "INTERLOCK state". The
function to keep the INTERLOCK state is called "Interlock function". The SEQ indicator is illuminated in
yellow in the INTERLOCK state.
The F3SG-SR has two Interlock functions, Start Interlock and Restart Interlock.

• Start Interlock

The F3SG-SR turns the safety outputs OFF at power-on or recovery from power failure and keep this
state until a reset signal is received. This is useful when you keep the machine stopped until a pre­operation check is completed after the power is turned ON.

• Restart Interlock

The F3SG-SR turns the safety outputs OFF when the F3SG-SR is blocked and keep this state until a
reset signal is received. Restart interlock is useful when you restart the machine being stopped upon
blocking the F3SG-SR, only after the operator confirms a safe condition.

The F3SG-SR has three ways to reset the INTERLOCK state: Auto Reset, Manual Reset, and Pre­Reset applicable to specific applications. Refer to 2-9. Pre-Reset for more information.

• Auto Reset mode

In the Auto Reset mode, the Start Interlock and Restart Interlock are disabled. When the blocking
object is removed from the detection zone, the INTERLOCK state is automatically released and the
safety outputs are automatically turned ON. The Auto Reset mode is desirable for application where
a worker is not able to enter the area between the detection zone and the hazardous part of the
machine or you use a relay unit to activate Start Interlock and Restart Interlock.

• Manual Reset mode

In the Manual Reset mode, the Start Interlock and the Restart Interlock are enabled. When a reset
signal is given while no blocking object exists in a detection zone, the safety outputs are turned ON.

Refer to 2-1. Combination of Functions for more information on the use in conjunction with other functions.

2-10. PSDI

To use the F3SG-SR in PSDI mode (initiation of cyclic operation by a presence sensing device),
you must configure an appropriate circuit between the F3SG-SR and the machine. For details
about PSDI, refer to OSHA 1910.217, IEC 61496-1, and other relevant standards and
regulations.

F3SG-SRA 
F3SG-SRB 

2-10-1. Overview

PSDI (Presence Sensing Device Initiation) is the function that F3SG-SR judges the unblocked/blocked
state of the detection zone and operates the machine cyclically (repeatedly). Operations of two-hand
push button switches are made unnecessary majorly on press machines, so operator’s burden can be
reduced and machine availability can be improved.
The following two types of PSDI can be realized without using controllers.

This function monitors if external relays (or contactors) operate normally to detect malfunctions, such as
welding, in the external relays. When the NC contact of the external relays is open before the safety
outputs switch from OFF to ON, the safety outputs remain in the OFF state. When the NC contact is not
open within the allowable delay time after the safety outputs switch from OFF to ON, the F3SG-SR enters
the LOCKOUT state.

 Basic wiring diagram

Perform wiring so that the specified voltage is applied to the RESET line via the NC contact of the
extenal relays. Refer to the table below for the specified voltage.

User’s Manual

2-13. Muting

The Muting and Override functions disable the safety functions of the device. Especially
setting the Muting Time Limit parameter to infinite may cause the safety functions to be
disabled for a long time. Install the F3SG-SR, muting sensor and physical barrier and
configure time settings for Muting and Override so that an operator should not enter
hazardous zone when the Muting and Override are active.

Install muting sensors so that they can distinguish between the object that is being
allowed to pass through the detection zone and a person. If the Muting function is
activated by the detection of a person, the machine may not stop operating, resulting in
serious injury.

Muting lamps 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.

Use two independent input devices for muting inputs. Failure to do so may cause the
MUTING state due to a single muting sensor's failure.

2-13-1. Overview

Muting function temporarily disables safety function of the F3SG-SR, keeping safety outputs ON even
if beams are blocked. This makes it possible to install safety light curtains for AGV passage, enabling
both safety and productivity. When muting is active, the area beam indicator (ABI) *1 or the TOP/BTM
indicator blinks to notify people around the sensor that the safety functions are disabled.
The following three operation modes are available for the Muting function.

1. Standard Muting mode (factory default setting)

2. Exit-Only Muting mode

3. Position Detection Muting mode

*1 F3SG-SRA is applicable.
*2 F3SG-SRB is applicable.

 Using muting function

<Muting sensor>
The muting sensor is the sensor to trigger a signal to temporarily disable the safety functions of the
F3SG-SR. You can use a photoelectric sensor of through-beam type or reflective type proximity
switch, or limit switch. (Recommended: OMRON E3Z series, E2E series (3-wire type), D4N series)
Use a 3-wire type transistor output, which is the same as the output type of the F3SG-SR, or NO type
contact. Two-wire type sensor must not be used.
The Intelligent Tap is necessary when using the Muting with the F3SG-SR in the Wiring
Synchronization.
The Intelligent Tap cannot be used when using the Muting with the F3SG-SR in the Optical
Synchronization.

When the F3SG-SR is in PNP settings, use the muting sensor of the PNP transistor type.

When the F3SG-SR is in NPN settings, use the muting sensor of the NPN transistor type.

<Muting lamp>
You may need a muting lamp depending on your application or as a result of a risk assessment
analysis. Before determining the use of the muting lamp, check laws and regulations of the country or
region where the F3SG-SR is used and make sure of full compliance with them. For the muting lamp,
use a commercially available external indicator.
The external indicator can be connected to the auxiliary output.

For settings of the auxiliary output, see 2-12. Auxiliary Output.

<LED indicator statuses>

Area beam indicator (ABI) *1 Blinks under the MUTING or OVERRIDE state.
TOP/BTM indicator *2
SEQ indicator Blinks during a muting sequence error.
CFG indicator If the Dynamic Muting function is enabled, the indicator blinks while measuring the

workpiece height.
If the Dynamic Muting function is enabled, the indicator turns on after the new

muting zone is determined.

*1 F3SG-SRA is applicable.
*2 F3SG-SRB is applicable.

For muting error indication, see 8-1-3-3. Muting Sequence Error Indication.

<Muting zone range>
You can specify a detection zone to be muted within the detection zone of the F3SG-SR.

Muting zone range Description

Full zone muted
(factory default setting)

Partial zone muted A specified area in the detection zone configured by the SD Manager 3 is muted.

Dynamic Muting This can be used by enabling the Dynamic Muting function.

Full area of the detection zone is muted.
This allows the safety function to be disabled in the full detection zone. This is a typical usage.

This can be used if you want to disable the safety function only in a specific area of the detection zone.
Setting the full detection zone for the muting zone allows the full zone to be muted.

The full detection zone is muted for a certain time period from the start of the muting, then a partial
zone is muted depending on the detected workpiece size.

2-13-5. Dynamic Muting

2-13-2. Standard Muting Mode

2-13-2-1. Overview

The factory default setting is set to this mode.
Turning the muting inputs A and B ON with time difference enables the Muting state.

Chapter2 Muting

 Start Conditions

If both of the following two conditions are satisfied, the MUTING state is enalbed.

1. No blocking object is found in the F3SG-SR's detection zone, and safety outputs are ON.

2. After the muting input A is turned ON*, the muting input B is turned ON* within the range between
the muting input time limit values T1min (0.1 s) and T1max (4 s).

*PNP setting: Vs-3V to Vs, NPN setting: 0 to 3V

The MUTING state can be enabled in up to 80 ms after the condition No.2 is satisfied.
When the condition No.1 is satisfied but the time requirement of the condition No.2 is not, a muting
sequence error occurs and the SEQ indicator on the receiver blinks. However, when there is a muting
sequence error, the F3SG-SR does not enter the MUTING state but it continues the normal operation
with the safety function enabled.

For muting error indication, see 8-1-3-3. Muting Sequence Error Indication.

The Muting error state can be released by any of following conditions:

1. Correct initial muting condition continues for 0.1 s or longer. *

2. Power cycle when the muting inputs A and B are in the OFF state.

* The correct initial muting condition is the state where the following two conditions are satisfied.

• Safety outputs of the F3SG-SR are turned ON.

• Muting input A and B are turned OFF.

 Installation requirements for muting sensors

• Set the muting sensors so that they can detect all of the passing detection (palettes, automobiles,
etc.). Do not install the muting sensor in a position so that only the front or rear end of the objects is
detected.

• Set the muting sensors so that they detect the objects even when they are loaded on palettes or
other transport devices.

• Also, install the F3SG-SR and muting sensors so that each object passes through all muting sensors
before the next object arrives at the first muting sensor. Also, install all F3SG-SRs and muting
sensors so that no person is able to accidentally enter the hazardous zone while the muting function
is enabled.

• If objects' speeds can vary, the allocation of muting sensors must be taken into consideration.

• 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.
