Nomenclature
Protective height
Series connection types
The F3S-B can detect in the area indicated by ”Protective
height” in the figure below. The protective height is from ”the
Optical-axis line mark above the indicator area” to ”the end of
the yellow metal case”.
When your application requires an additional protective zone,
for example, to prevent someone from staying behind a primary detection zone, the F3S-B may be connected in series.
The system consists of a master unit, a slave unit, and a series connection cable, type F39-JB1B.
The series connection allows up to 96 axes and 2.4 m of pro-
Optical-axis line mark
The center line for optical axes is indicated by the triangle
mark. This position is a reference line for measuring safety
distance.

Series connection types have the same characteristics as a

unit or that of the slave unit is interrupted, the outputs of the
master unit go to the OFF-state.

Note: The F3S-B is not in normal operation during connection with the F39-E1.
The control outputs are held in their OFF-state. For detailed information
please refer to “Details of F39-EU1E” in this data sheet.
!WARNING
After setting the blanking function, check that the F3S-B detects a test
rod at any position in the F3S-B detection zone through which a person reaches the hazardous part of the machine. If any positions are
found by check above, install protective structures to there to prevent
intrusion which F3S-B can not detect. Failure to do so may result in
serious injury.
Perform the installation check and the periodical inspection described
in the F3S-B manual.
Disconnect the outputs of the F3S-B from the load when programming it using the F39-U1E software and with F39-E1 interface unit.
Failure to do so may result in serious injury.
Do not connect the F39-E1 to a power supply with a voltage higher than
24 VDC +20 %. Do not connect the F39-E1 to an AC power supply.

1.3.2 Wiring Procedure
1. Connect the F3S-B (see the instruction manual of the F3SB for wiring.)
2. Connect the Interface cable (F39-JB1C) to the Interface
unit (F39-E1).
3. Connect the 4 wires of the Interface cable to each appropriate line of the F3S-B.
4. Connect an RS-232C cable to the PC and the Interface
unit.
1.4 Software-Installation
Copy the file „F39-U1E_ver#.#.exe“ and F39-U1E_ver#.#dat
from the enclosed 3.5-inch floppy disk onto the hard disk of
the PC.
2.2 Relay Monitoring
MPCEs (Machine Primary Control Elements) are usually relays or contactors used to control hazardous movement directly. The state of the MPCEs can be checked with the Relay
monitoring function.
A voltage of 17 VDC to Vs (Supplied voltage to F3S-B) has to
be applied to the Relay monitoring input through the NC contacts of the MPCEs when the F3S-B control outputs are in the
OFF-state (see the F3S-B manual for wiring information). To
ensure this logic relation, the MPCEs must be safety approved types, with forcibly guided contacts.
Allowed Relay Delay Time
The allowed relay delay time can be set between 20 and 300
ms. This delay time has to be set at least 20 milliseconds
shorter than the Outputs ON delay time.
2.3 Outputs ON Delay
You can set the ON delay time of control outputs between 80
and 400 ms. This corresponds to the time which the control
outputs go to ON-state after the detection zone is not interrupted.
Note: 1 . When the Relay monitoring function is also used, the ON delay time
must meet the formula below.
2 . ON delay time Allowed relay delay time + 20 ms After the Relay monitoring function is set, if the ON delay time does not meet the above
formula, the ON delay time will be changed automatically into ”Allowed
relay delay time” + 20 ms.
2.4 Blanking
With the Blanking function, one or more axes can be disabled.
This function is useful in an application where a part of the
F3S-B detection zone is always interrupted. The Manual-setting and the Teaching-setting are available to select the
blanked axes.
Note: 1 . In the case the blanked zone is not filled with structure completely and
remains some opening, the opening must be filled with the protective
structure.
2 . All axes can not be disabled. At least one axis needs to be active.
F3S-B
1.3 Hardware Connection
2. Function Description
2.1 Start Interlock
When the Start interlock function is used, the F3S-B does not
go to the ON-state automatically after power ON. Interrupting
one or more axes resets the start interlock condition of the
F3S-B then starts normal operation. The duration of the interruption must be equal or shorter as defined in the „Max. interruption time (sec)“.
Max. Interruption Time
The max interruption time can be set between 0.3 and 2 s.
Note: In the case both the Start interlock and the Start/restart interlock are selected, only the Start/restart interlock will be activate.

Precautions
!WARNING
1. Do not use the F3S-B on machines that can not be stopped by electrical control in case of an emergency.
2. Do not use the F3S-B in flammable or explosive environments
3. Always maintain the safety distance between F3S-B and a hazardous part of the machine. Serious injury may result if the machine does not stop before someone reaches the hazardous part.
4. Install protective structures around a machine so that you must pass through the detection zone to reach a hazardous part of
the machine.
5. Install F3S-B so that some parts of the operator’s body remain in the detection zone at all times when the operator works in the
hazardous area.
6. Failure to do so may result in serious injury.
Correct installation
Incorrect installation
A hazardous part of a machine can be
reached only by passing through the sensor detection zone.
A hazardous part of the machine can be
reached without passing through the sensor detected zone.
Some part of the operator’s body remains
in the detection zone while they are working.
A worker is between the sensor detection
zone and a hazardous part of a machine.
!WARNING
1. Be sure to install the F3S-B to minimize the effects of reflections from reflective surfaces. Failures to do so will create an inability
to detect and may result in serious injury
2. Install the F3S-B with a minimum distance D as shown below form the reflective surface (highly reflective surfaces) like metal
walls, floors, ceilings, and work pieces.

!WARNING
1. The F3S-B is a TYPE 2 Electro-sensitive protective equipment, intended to be used as or with the safety related part
of control system to category 2, 1 or B as defined in the European standard EN954-1.
Do not use the F3S-B in category 3 or 4 systems.
2. A qualified person, as determind by local regulations, must
confirm that installation, inspection and maintenance are
implemented correctly.
3. Do not short the output lines to the +24 V line. Doing so will
cause the output to be always ON, creating a hazardous situation.
4. Do not connect the F3S-B to a power supply with voltage
higher than 24 VDC + 20%. Do not connect the F3S-B to an
AC power supply.
5. Be sure to conduct inspections regularly.
6. The F3S-B cannot be used in applications where hazardous projectiles may exit the protected zone.
7. Do not disassemble, repair or modify the F3S-B.
8. DC power supply units must satisfy all of the conditions below so that the F3S-B can comply with the applicable standards IEC 61496-1 and UL 508.
(4.) The power supply automatically resets overcurrent
protection characteristics (voltage drop).
(5.) The power supply maintains an output holding time of
at least 20 ms.
(6.) FG (frame ground terminal) must be connected to PE
(protective earth) when using a commercially available
switching regulator.
(7.) The power supply must have output characterisitics required for the power source for Class 2 Circuit or Limited Voltage / Current Circuit as defined in UL508.
(8.) The power supply must conform to regulatory requirements and standards, regarding EMC and electrical
equipment safety, of the country where the F3S-B is installed and where machinery will be operated, for example: The EMC Directive (industrial environment)
and the Low Voltage Directive in EU.
9. Do not use the F3S-B in a direct retroreflective configuration. Otherwise detection may fail.
F3S-B
(1.) The power supply voltage must be within rating
(24 VDC ± 20%).
(2.) The power supply is connected only to the F3S-B and
to the electro-sensitive protective function of the F3SB, such as a safety controller and muting sensors, and
it has enough rated current for all the devices.
(3.) The power supply uses double or reinforced insulation
between the primary and secondary circuits.
