You can re-adjust sensitivity during detection without stopping the
operation.
The sensor continues operation with the previous sensitivity setting
until sensitivity readjustment is completed.
CUE: External calibration with several units
When several units are connected, the sensitivity of all the FS-T2(P)
expansion units can be simultaneously set using the external calibration input through the FS-V1(P).
You can select a unit to be externally calibrated by setting its key protection switch to the LOCK position.
External calibration is effective for all the units which are locked. Set
the key protection switch to LOCK on the FS-T2(P) expansion unit to
be externally calibrated.

• To connect a fiber unit with a small diameter, use the adaptor
included with the FU series.
1. Attach the adaptor to the fiber
unit.
2. Fully insert the adaptor into the
mounting holes of the amplifier,
and then lift the quick-release
lever.

• You cannot use the FS-V1(P)’s SET button to set the sensitivity of the
expansion unit.
• The red LED and green LED turn ON and OFF in response to the
expansion unit [FS-T2(P)] turning ON and OFF.
Note 1: You cannot control the [FS-M2(P)] (Manual calibration model).
Note 2: The channel for the [FS-M2(P)] is displayed as “------”. The
red LED and green LED turn ON and OFF in response to the [FSM2(P)] turning ON and OFF.
Note 3: If you add an FS-V20 Series expansion unit, you may not be
able to control the FS-V20 Series and any expansion units added after
the FS-V20 Series .
Note: If the fiber unit is improperly connected, the sensor cannot meet
the specifications.
• The required adaptor is included in each model of the FU series. If an
inadequate adaptor is used, the fiber unit cannot be properly installed.

MOUNTING MAIN UNIT
Mounting/Detaching the unit to/from a DIN rail or the
mounting bracket.
Hook the claw located at the unit cable side onto the DIN rail, and then hook the
front side claw to the rail while pressing the amplifier forward. To detach the
unit, unhook the front claw by lifting the unit front side while pressing it forward.
Mounting Detaching
MUTUAL INTERFERENCE SUPPRESSION FUNCTION
When using several fiber units, each fiber unit is free from light
interference from up to 4 adjacent fiber units.
When the fiber units are mounted closely, each fiber unit and its 4 adjacent units are designed to receive light at different pulse frequencies to
avoid interference.
MOUNTING EXPANSION UNITS
Mounting EXPANSION units
1. Detach the protective cover from the
unit’s side panel.
2. Mount units to a DIN rail one by one.
3. Slide one expansion unit toward
another. Align the front claws of the
units and push the unit together until
they click.
4. Fix the units together by pushing an
end unit onto each end. (The end units
are included in the expansion unit)
Detaching units from DIN rail
1. Remove the end units.
2. Slide the expansion units apart, and
detach them individually.
(Do not detach multiple units connected together with end units.)
• When several units are connected, confirm the ambient temperature. (See "Specifications" on P. 1.)
NOTICE
• To connect several units, be sure to use a DIN rail and end units.
• To mount or detach several units, be sure to turn the power off.
• Do not remove the protective cover of the expansion connector
on the outmost unit.

HINTS ON CORRECT USE
• To extend the cable length, use a cable with at least a 0.3 mm2
cross-section area. Limit the length of cable extension to no more
than 100 m. (To connect several units, contact Keyence for further
information.)
• If the amplifier cable is placed together with power lines or high voltage lines in the same conduit, detection error may occur due to noise
interference, or the sensor may be damaged. Isolate the amplifier
cable from these lines.
• When using a commercially available switching regulator, ground the
frame ground terminal and ground terminal.
• Do not use the FS series outdoors, or in a place where extraneous
light can enter the light receiving surface directly.
• During maximum sensitivity setting, the detecting distance may vary
due to the difference in characteristics of each unit.
• When the stability output is not used, cut the orange cable at the root
or connect it to the 0 V (“+” for PNP output model) terminal of the
power supply, in order to avoid contact with other cables.
• When the external calibration is not used, cut the pink cable at the
root or connect it to the “+” (“0 V” for PNP output model) terminal of
the power supply, in order to avoid contact with other cables.
