Indications and Meanings for Safe Use
The precautions listed in this document indicated by alert symbols and statements must
be followed for the safe use of the F3SG-SR. Failure to follow all precautions and alerts
may result in an unsafe use or operation.Thoroughly read this document before using
the F3SG-SR. The following word and symbols are used in this document.
Alert Statements
DANGER
Make sure that the machine can be controlled correctly and as
intended. Also make sure that the machine can be stopped
immediately at any time of the operation cycle without danger to
machine operators when the machine behavior does not meet
safety-related requirements. Otherwise, continued use of the
machine may result in serious injury or death.
Users
WARNING
The F3SG-SR must be installed, configured, and incorporated into a
machine control system by a sufficiently trained and qualified person.
An unqualified person may not be able to perform these operations
properly, which may cause a person to go undetected, resulting in
serious injury.
Machines
WARNING
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
WARNING
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.
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.
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 to activate the Override function 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.
When muting error occurs with workpiece blocking the F3SG-SR, there are two
methods to forcibly remove the workpiece.
1) Manual operation (with additional safety measure); or
2) Override function (Override at Normal Operation / Override upon Startup)
Only one of the methods, either 1) or 2) must be used.
If they are used at the same time, the Override may be activated at an unexpected timing.
Install the F3SG-SR so that it is not affected by reflective surfaces. Failure to do so
may hinder detection, 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.
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.
Do not use the F3SG-SR with mirrors
in a retro-reflective configuration.
Mirror
Doing so may hinder detection.
It is possible to use mirrors to alter
the detection zone to a 90-degree
angle.
Position with retro-reflection
Wiring
WARNING
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.
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.
• 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
