Proper use
1 Proper use
The SRP system uses a linear motor to adjust the presser foot pressure to the actual sewing
speed or workpiece. In addition the presser foot clearance can be adjusted individually.
The adjustments are made by altering parameter values, see Chapter 2.02.03 Selecting/
altering parameters.
Any and all uses of this machine which have not been approved of by the
manufacturer are considered to be inappropriate! The manufacturer cannot be
held liable for any damage caused by the inappropriate use of the machine!
The appropriate use of the machine includes the observance of all operational,
adjustment, maintenance and repair measures required by the manufacturer!

2.02 Control panel

The control panel consists of display 1 and the function keys described below. The display
1 consists of a two-line alpha-numerical LCD display with 16 symbols per line. The texts 3
show the respective status of the function keys and the operating status of the machine.
The control panels switches on all LCD-segments and the horn automatically for a short time
during the power-on phase, after which the lettering PFAFF appears on the display, until the
higher-ranking control unit sends commands to the control panel.

Activated functions are displayed with a triangular marking 2 below or next to the respec-

●
In the sewing mode all relevant sewing data is displayed and these can be changed di
rectly, depending on the status of the machine, see also Chapter 5 Sewing.
●
During the parameter input the selected parameter number with the corresponding value
is displayed, see Chapter 2.02.03 Selecting/changing parameters.
2.02.02 Function keys
The function keys described below are used basically to switch machine functions on and
off.
If a corresponding value has to be set for the activated function, this is carried out with the
corresponding +/- key. By pressing and holding the corresponding +/- key, the appropriate
numerical value 4 is changed slowly to begin with. If the corresponding +/- key is held down
longer, the values change more quickly.
Start backtacks
If this key is pressed, the backtacks at the beginning of the seam (start backtacks) are
●
switched on or off. The number of forward stitches (A) or reverse stitches (B) for the start
backtacks can be changed by pressing the +/- key underneath. To convert from double
backtack to single backtack set the corresponding number of stitches at zero.

Controls
End backtacks
If this key is pressed, the backtacks at the end of the seam (end backtacks) are switched
●
on or off. The number of reverse stitches (C) or forward stitches (D) can be changed by
pressing the +/- key underneath. To convert from double backtack to single backtack set
the corresponding number of stitches at zero.
Needle position
If this key is pressed the corresponding function is switched on or off. When the function
●
is switched on, the needle positions at t.d.c. after sewing stops.
Foot position after stop
●
If this key is pressed the corresponding function is switched on or off. When the function
is switched on, the presser foot is raised after sewing stops.
Foot position after trimming
●
If this key is pressed the corresponding function is switched on or off. When the function
is switched on, the presser foot is raised after thread trimming.
Thread trimmer
If this key is pressed the thread trimming function is switched on or off.
●
Speed (only in programmed sewing)
If this key is pressed the corresponding function is switched on or off. In the seam pro-
●
gram the speed is not dependent on the pedal. When the function is switched on, the
speed cannot be adjusted by pedal. Sewing can only be carried out at the set maximum
speed.
●
If the function is switched off, the speed up to maximum speed is adjusted by the pedal.
Reverse sewing
●
If this key is pressed the reverse sewing function is switched on or off.
Manual seam (only in programmed sewing)
If this key is pressed the machine switches to manual sewing. When the function is swit-
●
ched on, the move to the next seam section is not carried out by stitch counting or sensor, but manually with the use of the pedal (position "-2").
Stop
If this key is pressed the corresponding function is switched on or off. When the function
●
is switched on, the machine stops automatically at the end of a seam section.
Sensor
●
In manual sewing the number of compensating stitches from the point where the photo
cell is light to the end of the seam can be set under parameter 111, and in programmed
sewing directly.

Stitch counting
If this key is pressed the corresponding function is switched on or off. The value for the
●
compensating stitches can be changed immediately with the corresponding +/- key.
When the function is switched on, the machine moves to the next seam section after se-
wing the number of stitches entered.
TE/Speed
In the programmed sewing mode, the number of stitches is entered by stitching them
●
off.

Scrolling
●
If this key is pressed in the programmed sewing mode, the machine scrolls through the
input menus on the display.
PM
If this key is pressed the programmed sewing function is switched on or off. When the
●
function is switched on, the letters "PM" appear on the display of the control panel. The
parameters related to the program are shown in the alpha-numerical part of the display.
