CUE: Calibration input during detection

You can re-adjust sensitivity during detection without stopping theoperation.The sensor continues operation with the previous sensitivity settinguntil 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 externalcalibration 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) expansionunit to be externally calibrated.

CONNECTING FIBER UNIT

Lower the quick-release lever, insert the fiber unit about 14 mm until itreaches the end, and then lift the quick-release lever.

To connect a fiber unit with a small diameter, use the adaptor

included with the FU series.

1. Attach the adaptor to the fiberunit.

2. Fully insert the adaptor into themounting holes of the amplifier,and then lift the quick-releaselever.

Note: If the fiber unit is improperly connected, the sensor cannot meetthe specifications.

The required adaptor is included in each model of the FU series. Ifan inadequate adaptor is used, the fiber unit cannot be properlyinstalled.

To connect the coaxial reflective type fiber unit to the amplifier,connect the single-core fiber to the transmitter side, and connect themultiple-core fiber to the receiver side.(Connect the fibers according to the marking on the amplifier lateralside.)

1. Detach the protective cover from theunits side panel.

2. Mount units to a DIN rail one by one.3. Slide one expansion unit toward

another. Align the front claws of theunits and push the unit together untilthey click.

4. Fix the units together by pushing anend unit onto each end. (The endunits are included in the expansionunit)

sDetaching 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.)

Note 1: When several units are connected, confirm the ambient temperature.(See "Specifications" on P. 1.)Note 2: To connect several units, be sure to use a DIN rail and end units.Note 3: To mount or detach several units, be sure to turn the power off.Note 4: Do not remove the protective cover of the expansion connector on theoutmost unit.

MUTUAL INTERFERENCE SUPPRESSION FUNCTION

When using several fiber units, each fiber unit is free from lightinterference from up to 4 adjacent fiber units.When the fiber units are mounted closely, each fiber unit and its 4adjacent units are designed to receive light at different pulse frequen-cies to avoid interference.

You can mount the FS-T(P) series andthe FS-M(P) series together within thesame system.

Note: If you do not use the expansion-

units, the mutual interference suppressfunction is not available.

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 morethan 100 m. (To connect several units, contact Keyence for furtherinformation.)

If the amplifier cable is placed together with power lines or highvoltage lines in the same conduit, detection error may occur due tonoise interference, or the sensor may be damaged. Isolate theamplifier 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 ofthe power supply, in order to avoid contact with other cables.

When the external calibration is not used, cut the pink cable at theroot or connect it to the + (0 V for PNP output model) terminal ofthe power supply, in order to avoid contact with other cables.
