Starting up

● Before the machine is put into operation for the first time, clean it thoroughly and oil it (see page 8).

● Check whether the belt guard is mounted (see page 7).

● Before the machine is switched on, connect compressed air and check air filter/lubricator (see

page 8).

● Ask a technician to check if the motor may be operated with the available mains voltage and if it is

properly connected in the junction box.
Never operate the machine if this is not the case.

● The encoder adjustment must only be carried out by persons with appropriate training

(see page 6).

● The maximum sewing speed is 3200 s.p.m.

3. Switch functions

Function knee switch ON/OFF is selected with sub-function KNEE SWITCH. If ON is selected, all
freely programmable programs (program number 3 to 24) will be converted for knee switch. If OFF is
selected, all freely programmable programs (program number 3 to 24) are converted for grading.

Via sub-function LANGUAGES the language for the dialog in the display is determined.

4. Counter

With sub-function SLOW START STITCHES the number of stitches is inputted that will be performed at a
reduced speed in sewing mode.
With sub-function PEDAL PARAMETERS the degree of pedal delay (0 = little delay, 9 = large delay) is
inputted.

5. Speeds

With the sub-functions it is possible to input the maximum speed and the speed for the slow start
stitches.

6. Service

With this main function the user can check some of the hardware functions and the control. In addition,
he can carry out some settings on the sewing drive.

24 PFAFF

Programming options

The following programs/sewing procedures are
possible:

Changing the stitch lenght (e.g. to 2.5 mm)

Program 0 = Manual sewing

Program 1 = Sewing with two different seam

segments

Program 2 = Sewing with three different seam

segments

Note: Programs 1 and 2 are fixed programs. The

seam segments (different roller presser feed
motions) are incremented by operating the
knee switch and repeated until the treadle
is actuated to the 2nd backwards position.
The knee switch is automatically enabled.

Program 3 to 24 = Freely programmable with up

to 15 seam segments each for
right and left hand sleeve.
In the segment display an R
indicates the right hand sleeve
and an L the left hand sleeve.
In addition the current segment
(1 to 15) is indicated.
The programs can be pro­grammed so that it is possible to
increment the sewing segments
either via the knee switch (knee
switch must be enabled) or via
measurement of seam length
(seam lengths are learned,
knee switch must be disabled).
Grading, however, is only
possible when incrementing via
measurement of seam length.

and

Programs 3 to 24 are freely programmable with up
to 15 seam segments each for the right and left
hand sleeve.
There are two possibilities of incrementing the
seam segments:

1. Via knee switch (knee switch must be enabled)
The operator sews the seam segment right up
to the mark (pink) and increments by means of
the knee switch to the following seam segment.
Grading is not possible in this case.

2. Via measurement of length (knee lever must be
disabled)
The control increments automatically to the
following seam segment as soon as the pro­grammed seam segment is finished. In this case
grading is possible.

Determine the roller presser feed motion for fullness application

Example: seam segment 2 (fig. 20)

Length of seam segment 2, measured at sleeve hole = 100 mm
Selected stitch length (feed wheel) = 2.5 mm
Number of stitches in seam segment 2 = 40 stitches
(100 mm : 2.5 mm stitch length)

Lenght of seam segment 2, measured at sleeve = 112 mm
Roller presser feed motion: 112 mm : 40 stitches = 2.8 mm

Note:
Depending on the feed behaviour of the material used in the process and on the location of the seam in
relation to warp and weft threads it may be necessary to edit the determined value a little bit.

Basic sizes and size tables for grading

Grading means the gradual derivation of smaller and larger sizes from a certain basic size (see fig. 21).
The basic sizes that are indicated in the relevant tables constitute the basis for the creation of sewing
programs with grading.
Based on these basic sizes the control increases or decreases the seam segments with grading by the
factor indicated in the table when another size is selected. Grading values from 0 to 50 mm can be
inputted.

Example: 1 mm grading in seam segment 1

4 mm grading in seam segment 2

Length of seam segments in basic size 50 (factor 0)

Seam segment 1 = 35 mm
Seam segment 2 = 100 mm

Length of seam segments in size 48 (factor -1)

Seam segment 1 = 34 mm
Seam segment 2 = 96 mm

Length of seam segments in size 56 (factor 3)
