    3.7.2 Setting the plunger (Fig. 12) Blind stitch settings for thick fabrics as shown in Fig. 12a and for thin fabrics as shown in Fig. 12b. The plungers are placed centrically in the needle plate opening and 0.2 mm left from the needle shaft center (Fig.

  • Page 28: Setting The Cloth Support Arm (Fig. 11)

    3.7.3 Setting the cloth support arm (Fig. 11) Set the cloth support arm upwards by means of the stitch depth regulation until the needle is lifted by 0.2 mm by means of the left plunger in its upper cusp point. Use threaded pin (8) to limit the maximum height of the plunger and fixate with threaded pin (9).

  • Page 29: Thread Trimmer (Fig. 14)

    Thread trimmer (Fig. 14) The blade of the thread trimmer is activated by a rotary magnet, to which an electric release control system (microswitch) is connected. This prevents the machine from starting when the blade is no longer in its inital position. Thus the release control system prevents a possible collision between blade and looper.

  • Page 31: Adjustment (Fig. 14)

    3.8.2 Adjustment (Fig. 14) The thread trimmer drive must be inserted as far as it will go into the needle plate clamp. Swivel the drive backwards so that there is a gap of about 1 mm between the drive and the sewing head. The blade of the knife has until about 2 - 3 mm from needle lever, stand forward, readjust if necessary.

  • Page 32: Replacing The Knife (Fig. 14)

    The machine should be positioned in such a way as the pedal is stepped back that the distance between looper and blade in cutting position is approx. 1 mm. For Strobel and EFKA controls, this corresponds to parameter 171, position P2E.

  • Page 33: Positions

    3.11 Positions Parameter Function F-170 Setting the reference position This function sets the reference position. Parameter Function F-171 Setting positions 1 and 2 This function sets the two positions. The AB611A control has two positions. The positions are set exclusively by programming the control.
  • Page 34 Reference position: Turn hand wheel in the direction of the machine until the tip of the needle lines up with the right (inner) edge of the needle glide washers in the stitch-in direction. For that the right plunger needs to be up (Fig. 16). Fig.
  • Page 35 Notes for sewing drives which have two needle positions (i.e. sewing drive DC1210-AB611A (Fig. 18)): The above mentioned needle position is position 2 at the sewing drive. Position 1 must be set at the sewing drive in such a way, that the point of the needle (1) in the direction of stitch exit closes with the right (inner) edge of the needle slide plate.

  • Page 36: Setting The Positions

    3.12 Setting the positions 3.12.1 General notes The individual positions of the machine (machine positions) can be found in the operating manual of the sewing machine. N O T E ! For sewing machines that actually need only one position, both positions always need to be programmed anyway for the control programming.

  • Page 37: Setting Positions 1 And 2

    3.12.3 Setting positions 1 and 2 After entering the code number “1907” and button “E” for the technician level: - Select parameter F-171. Display shows: .1.7.1. - Press “E” button. Sr2_ - Press “>>” button. Turn the handwheel in the machine's direction of rotation until “P1E”...

  • Page 38: Display Of The Needle Positions

    At least one cycle needs to be sewn so that the setting is saved before the machine is switched off. For class VEB200-1, -1F, -2, -2F: position 1 position 2 For class VEB200-1RF, -2RF: position 1 position 2 Depending on the looper and needle setting, the values could variate slightly.

  • Page 39: Pneumatic Lifting

    3.14 Pneumatic lifting A T T E N T I O N ! Switch off machine electrically! 3.14.1 Setting the lifting Reduce the lifting speed of the cloth support arm at the one-way restrictor so that there is no hard noise when the arm is lowered. The piston in the pneumatic cylinder should move up to the limit stop.

  • Page 40: Seam Lock (Fig. 19)

    3.16 Seam lock (Fig. 19) The seam lock is made at the seam end by lifting the feed dog. Therefore the feed dog is lifted, the plunger is lowered and a second thread tension is activated. Fig. 19 3.16.1 Setting the feed dog at the seam lock The feed dog height is set by means of pneumatic cylinder (1) through lever (2) and eccentric bush (3).
  • Page 41 ATTENTION: Set the feed dog in a way that during the end seam lock and the programmable seam lock (lifted position) neither looper nor looper shaft touch the feed dog in the upper part. In the lower part the feed dog should move just above the material but should not catch it.
