  • Page 12: Optical Output Sensor

    1 - GENERAL FEATURES 1.6 OPTICAL OUTPUT SENSOR The optical sensor featured by the yarn feeder provides automatic speed adjustment based on the quantity of yarn needed by the machine. For very fine yarn count processing (lower than 40 den), the sensor requires DIP SWITCH settings (paragraph 4 refers).

  • Page 13: Yarn Output Detection Feeler

    1 - GENERAL FEATURES 1.8 YARN OUTPUT DETECTION FEELER The assembly of this detection feeler onto the feeder output, enables the machine to receive a stop signal that is relayed by the feeder when it detects output yarn snaps/breaks. Installation: once the feeler has been fixed onto the feeder using the nuts and bolts provided on the support bracket, connect up the wire with the three-way connector located on the feeder housing.

  • Page 14: Installation And Start-Up

    2 - INSTALLATION AND START-UP 2.1 YARN FEEDER INSTALLATION AND START-UP N.B.: Yarn feeders that are moved from warehouse storage into a warmer knitting mill environment may develop condensation; please wait until they are completely dry before connecting them up. Failure to do so may damage the electronic components.
  • Page 15 2 - INSTALLATION AND START-UP DC version The yellow/green cable (I) must be kept facing the signal lamps (C) (if the ca- ble strip is supplied by LGL, the yellow/green cable (I) can be identified by the arrows (L) printed on the cable strip). N.B.: Ensure that the stand onto which the yarn feeder is fastened is electrically grounded.
  • Page 16 2 - INSTALLATION AND START-UP HORIZONTAL SET-UP VERSION For the installation of the feeder onto the machine, proceed as follows: - using screw (G) fix clamp (F) underneath the feeder; fix the clamp onto the machine tube using the grub screws (H) located in the clamp, and position the yarn feeder so that it is set into the exact angle required for operation.
  • Page 17 2 - INSTALLATION AND START-UP - Connect up the feeders to the flat power cable (I) by means of the appropriate locking plate (L) then tighten it in with screw (M) located on the housing. CAUTION: when connecting the flat power cable, keep to the printed reference marks showing the exact fixing position (the arrows (N) must point towards the front end of the feeder).

    2 - INSTALLATION AND START-UP 2.4 DETECTION OF YARN BREAKAGE ON FEEDER OUTLET: KLS KIT This kit allows any irregular use of yarn by the machine to be detected without using any mechanical sensors. These sensors bring about undesired changes in yarn tension that are likely to negatively affect the overall efficiency of the equipment.

    3 - THREADING AND ADJUSTMENTS 3.1 THREADING YARN FEEDER WITH THE TWM TENSION MODULATOR Yarn feeder threading must be carried out when the device is OFF and as illustrated below: PARTIAL THREADING COMPLETE THREADING COMPLETE THREADING ATTIVO VERSION To avoid damaging the TWM we recommend use of threaders that are in good condition with no yarn accumulation around the threader-ends.

  • Page 23: Speed Adjustment

    3 - THREADING AND ADJUSTMENTS 3.2 SPEED ADJUSTMENT The yarn feeder is provided with a microprocessor and an output sensor that enable automatic speed adjustment that conforms to machine feeder speed. No speed adjustment is therefore required by the operator. For applications that may require special operational conditions, please consult subsequent paragraph 4 herein.

  • Page 26 4 - OPERATIONAL PARAMETERS AND YARN CONSUMPTION KIT On the first and on the last feeders that are fitted on the machine, DS4 shall be set to ON (Bus termination). Practical example: A yarn consumption kit has been installed onto the machine and a further number of feeders must now be added on.

  • Page 27: Maintenance Operations

    5 - MAINTENANCE OPERATIONS 5.1 REMOVAL OF THE YARN SPOOL BODY Proceed as follows to remove the yarn spool body: 1) Power down the yarn feeders by actuating the main switch located on the knitting machine. 2) Disconnect the flat strip power cable and disassemble the feeder. Lift it off the machine.
  • Page 28 5 - MAINTENANCE OPERATIONS 4) Unscrew the screw (16) that fastens the plug and remove both items; unscrew the 3 fastening screws (13) that are on the thread winding cone (4) and remove the latter. 5) Remove the absorber that is fastened to the teetered hub by unscrewing the related fastening screws (18).
  • Page 29 5 - MAINTENANCE OPERATIONS 7) Remove the winding assembly by taking it out of the shaft; the thin protection sheet (20) can be replaced by unscrewing the 3 fastening screws (21). The assembly shall be later fit back in place by matching the hole where the thin sheet is not fastened, as shown in the figure.
  • Page 30 5 - MAINTENANCE OPERATIONS 9) Removal of the front magnet holder (28) must be carried out using the appropriate tool (29) that needs to be fixed onto the magnet holder being removed, using the three fixing screws (13) belonging to the yarn spool body.

    5 - MAINTENANCE OPERATIONS 10) At this point the flywheel (30) can be removed. It is now also easy to replace the ceramic bushing (31) located in the yarn feeder shaft. 5.2 REPLACEMENT OF THE MAIN ELECTRONIC CONTROL BOARD The main electronic control board can only be replaced by a regularly authorised L.G.L.

  • Page 32: Component Replacement

    6 - COMPONENT REPLACEMENT 6.1 REPLACEMENT OF THE TWM TENSIONER For removal of the TWM tension modulator proceed as follows: 1 Turn the knob until the tensioner (33) reaches the end of its run, at number 0 on the index scale (Figure A). In cases when the ATTIVO tensioner is provided, press the release pushbutton.
  • Page 33 6 - COMPONENT REPLACEMENT 3) Remove the tensioner (33). Pay careful attention to the way in which the springs are attached to the TWM: the spring-hooks must be hooked into place so that they face outwards from the TWM. This to prevent them from coming into contact with the truncated cone and damaging it.

  • Page 34: Attivo

    7 - ATTIVO 7.1 ATTIVO ELECTRONIC TENSIONER ATTIVO is an electronic system that has been purposely conceived to hold yarn tension constant and programmable. The output sensor provides a real- time measurement of the output tension and an electric motor uses this value to adjust the position of the TWM tensioner.

  • Page 35: Offset

    7 - ATTIVO 7.2 OFFSET Upon first installation of this device, you need to enable the tension sensor to acquire the OFFSET function (mechanical error zero function). Follow the procedure below: - Remove the yarn from the tension feeder. - Switch off the feeder. - Press the release button and hold it pressed until the device light turns on.
