FIBER OPTIC SENSORS - GENERAL DESCRIPTIONFiber optic sensors function electronically like anyother photoelectric sensor with the di�erence that thelight emitted and received is transported by an optical�ber the end of which is very small and in di�erentforms and it can be installed some distance from theelectronic circuit.The reduced dimension of the �ber allows the sensingof very small objects and their installation in areaswhere other sensors would not �t.Furthermore they can be used in explosion risk areas aswell as in liquids and have a very high resistance tomechanical damage and to vibrations which makesthem suitable for installation on machinery weremovement is involved.They are available in the re�ection and barrier emit-ter/receiver.The light source is red and the length of the standard�bers is 2 metres.
DIRECT REFLECTION
FT18M-CFR WITH FIBERS FOR DIRECT REFLECTIONIn this type of function the red light emitter andreceiver are contained in one �ber (MULTI CORED)or side by side (DOUBLE CORED).The sensing is obtained by the re�ection of the raysof the object to be detected. The parameters thatin�uence the sensing distance are mainly the colour,the re�ective or the roughness of the surface to besensed.The maximum sensing distances mentioned in thetechnical characteristics refer to results obtained witha piece of matt white paper dimension 10 x 10 cm.
TYPES
Checking the missing terminals
Checking the form of components
THRU BEAM
FT18M-CFR WITH BARRIER FIBERSEMITTER/RECEIVERIn this type of function the red light emitter andreceiver are facing each other and are made up of asingle �ber (SINGLE CORED).Detection occurs when the rays emitted are inter-rupted furthermore these �bers can reach at theirmaximum sensitivity regulation, long distances asthere is no dispersion between emitter and receiver.Their power can be increased by using the AT-4101lenses.

FIBER OPTIC SENSORS - OPERATING PROCEEDURESINSTRUCTIONS FOR THE PROGRAMMING AND ADJUSTMENT
PNP
NPN
TRIMMER FOR THE SENSING RANGE ADJUSTMENT: The photocell is supplied with max. sensing range with the trimmertotally rotated in the clockwise direction. The sensitivity reduces by rotating the trimmer in the anti-clockwise direction.
SWITCH NPN/PNP: The photocell is supplied with the switch in P (PNP output).To change to NPN turn the switch to N in the anti-clockwise direction.WARNING! For a correct working of the unit, do not carry out the switching when the photocell is powered.
GREEN LED - STABILITY INDICATOR: This led is on when the level of the output signal and the alignment of thephotoelectric sensors are in the optimum position. In the case that the led is off this indicates that the lens is obscuredor for the types with direct reflection a possible alteration of the dimension or color of the object to be detected.
YELLOW LED - OPERATION INDICATOR: This led is on when the object to be detected enters the sensing range ofthe photocell giving output signals.
N.B. SENSITIVITY ADJUSTMENT• After adjustment the sensitivity can vary depending on variations in the object or conditions in the area of installation.• As reflection varies in relation to the object, adjustment should be carried out with the object present.• After having carried out adjustment, the fixing of the way and the curvature of the fiber should not be changed.
PROCEEDURE FOR THE DIRECT REFLECTION FIBER OPTICS ADJUSTMENT:Adjust the sensitivity to minimum turning the trimmer anticlockwise.Position the object to be sensed at the required distance in relation to theend of the fiber and turn the trimmer slowly clockwise until the yellow ledlights up. Continue turning the trimmer until the green led lights up. Re-check that the calibration is correct by using the object and possibly byrepeating the proceedure.IMPORTANT: in the presence of objects to be sensed the yellow led shouldbe illuminated.Output functions in the absence of the objects to be sensed.NO output = black wire (H version = PIN 4)NC output = white wire (H version = PIN 2)
PROCEEDURE FOR THE THRU-BEAM FIBER OPTICS ADJUSTMENT:
Adjust the sensitivity to minimum turning the trimmer anticlockwise.Position the end of the fibers at the required distance and turn the trimmerslowly clockwise until the yellow led lights up. Continue turning the trim-mer until the green led lights up. Re-check that the calibration is correct byusing the object and possibly by repeating the proceedure.IMPORTANT: in the presence of objects to be sensed the yellow led shouldbe illuminated.Output functions in the absence of the objects to be sensed.NC output = black wire (H version = PIN 4)NO output = white wire (H version = PIN 2)
PROCEEDURE FOR ASSEMBLING FIBERS IN THE FT18M-CFR
1) Position and screw thelocknut in the sensor loo-sely.
2) With the locknut looseinsert the fibers in the tworeceptacles.
3) With the locknut loose in thefibers ensuring that theyreach the end.
4) Tighten the locknut carefullyand ensure that, at the end ofthe operation, the fibers areblocked.

FIBER OPTIC SENSORS - NOTES AND CAUTIONS FOR CORRECT OPERATIONS
FIBER OPTIC - CHARACTERISTIC CURVES
FIBER PROBES
Cutting-free type plastic fibers can be cut by the optional cutter (AT118) at anydesired lengthCut the plastic fiber before connection. Make sure to cut it sharply since thestatus of cutting surface influences to the sensing distance which might bereduced by up to 20%.Cutting should be done sharply by one action, and do not use the same holemore than once.
FIBER FIXING
Use the supplied spring lockwasher for fixing the fibers with threaded bushingin order not do damage the fibers with excessive force.When fixing the non-threaded head type with a set-screw (M3 max.) as indi-cated on the left side scheme, apply a torque of 3 kgf/cm max.
CONNECTION OF DIRECT REFLECTION MULTI-CORED FIBER
Put the SINGLE-CORED fiber to the LIGHT-EMITTER side and the MULTI-CORED fiber to the RECEIVER side.
STAINLESS SLEEVE FIBERS
The fibers with this type of terminal are very useful when the installation isdone in locations not easily accessible and this can be obtained bending thesleeve in relation to the required position.Make the bending radius to be processed on anneals stainless sleeve on thesensing head as large as possible according to the sleeve diameter rate as indi-cated on the left side scheme.
