  • Page 32: Using The Equipment

    USING THE EQUIPMENT: We describe below the optimal utilisation method for the SK3 needle path detector. 1) When the machine is powered and started, the operating mode is manual. 2) The operator performs the drawing-in process and places the fabric in front of the microcamera.
  • Page 33 SK3 NEEDLE PATH DETECTOR Page 33 of 46 14) In the event of the line being stopped by a reason other than an alarm condition, for instance when it is stopped by the operator, the automatic mode is maintained, and will be effective again as soon as the line is restarted.

  • Page 55 To calibrate the sensor SK3, you must move the camera vertically to get the blue line (transparency) as flat as possible, or with the two ends slightly lower, as seen in photos. BEST SIGNAL OBTAINED AFTER CALIBRATION INSERT A SCREWDRIVER BETWEEN THE CAMERA AND THE PROJECTOR AND CHECK THAT THE LINES T (TRANSPARENCY) AND R (REFLEX) FOLLOW THE FAKE SLITTING LINE.
  • Page 56 CENTRE SLITTING LINE RIGHT SLITTING LINE LEFT SLITTING LINE Once you reach the optimal position, firmly tighten the screws loosened to move the camera. And WE recommended,( with a permanent marker), to make marks on the supporting arm at the setting position so if the camera is removed for any maintenance, you can reassemble without repeating the steps of calibration.
  • Page 57 15) Insert a fabric with slitting line to start the machine, select the reading mode in TRANSPARENCY ("0." On the display card's C336), adjust the alarm threshold, enter the AUTO mode and see that the basket rotates to bring the deviation of the missing needle in the center.
