Nomenclature

Protective height

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”.

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.

Stand-alone type

This is the most common configuration, and it is used to pro­tect a hazardous part of a machine when approached from
one direction only.

Series connection types

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 pro­tective height in total.
Series connection types have the same characteristics as a
stand-alone types. When the detection zone of the master
unit or that of the slave unit is interrupted, the outputs of the
master unit go to the OFF-state.

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.

information.

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. 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 se-

lected, only the Start/restart interlock will be activate.

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

Open Output 2 (White 1)

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

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

must meet the formula below.

2 . ON delay time Allowed relay delay time + 20 ms After the Relay mon-

itoring 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.

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.

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 work-

A worker is between the sensor detection
zone and a hazardous part of a machine.

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.
(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.

(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 re-

quired 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 require-

ments 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.
