1 Operating elements of the S2 control panel
The control panel is used to create and alter seam programs, enter parameter values and
read error messages and service settings.
The control panel consists of display 1and the function keys described below. Display 1
consists of a two-row, alpha-numerical display with 16 symbols per row. The special
symbols 3and texts 4 show the respective status of the function keys and the operating
modes of the machine.
During the power-on phase the control panel automatically switches on all LCD segments
and the horn. The number of the version of the installed software then appears on the
display, until the higher-ranking control unit sends commands to the control panel.
1.01 Screen displays
●Activated functions are displayed with a triangular marking 2below or next to the
respective function key.
●In the sewing mode all relevant sewing data is displayed and these can be changed
directly, depending on the status of the machine, see also Chapter 2 Sewing.
●During the parameter input the selected parameter number with the corresponding value
is displayed, see Chapter 2.06 Parameter settings.
1.02 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. For example, by pressing and holding the +/- key 5, the numerical
value 6shown above the key is changed slowly to begin with. If the +/- key 5 is held down
longer, the numerical value 6is changed more quickly.

Controls
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 number of stitches for the corresponding seam
section at zero.
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 number of stitches for the corresponding seam section at zero.
Needle position
●If this key is pressed the "needle raised after sewing stop" 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 "foot raised after sewing stop" function is switched on or off.
When the function is switched on, the presser foot is raised after sewing stops.
Foot position at end of seam/or after a seam segment (in programmed sewing)
●If this key is pressed the „Foot position raised at the end of a seam“ function is switched
on or off. When the function is switched on, the presser foot is raised at the end of a
seam.
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 programmed
sewing the speed is not pedal-controlled. When the function is switched on, the speed
cannot be controlled by pedal. The machine only sews at the set maximum speed.
●When the function is switched off, the speed is controlled up to the maximum speed by
pedal
Reverse sewing (only in programmed sewing)
●If this key is pressed the corresponding function is switched on or off. When the function
is switched during programmed sewing, the corresponding seam section is sewn in
reverse.
Manual seam end (only in programmed sewing)
●If this key is pressed the corresponding function is switched on or off. When the function
is switched 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").

Controls
Programmed stop (only in programmed sewing)
●If this key is pressed the corresponding function is switched on or off. When the function
is switched on, in programmed sewing the machine stops automatically at the end of the
seam section.
Photocell
●In manual sewing the number of compensating stitches from the point where the
photocell is light to the end of the seam can be set under parameter 111, and in
programmed sewing directly.
Stitch counting (only in programmed sewing)
●If this key is pressed the corresponding function is switched on or off. When the function
is switched on, in programmed sewing the machines switches to the next sewing
section after the number of stitches entered have been sewn.
TE/Speed
●If this key is pressed once while the machine is in the sewing mode, the input menu for
the maximum speed is selected. If no input is made within 5 seconds, the sewing mode
is selected again.
●If this key is pressed twice (within 5 seconds) while the machine is in the sewing mode,
the machine switches to parameter input.
●If this key is pressed once while the machine is in the parameter input mode, the altered
values are stored and the sewing mode is selected.
Scrolling
●If this key is pressed, the machine scrolls between the sub-menus in the program.
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.
F1
Press this key to sew a single stitch (only with control unit P70 ED)
F2
Piece counter (only with control unit P70 ED)
When this key is pressed the first time, the piece counter is displayed for 3 sec.
If pressed again during the display period, the piece counter is reset.
The piece counter only counts when the "thread trimming" function is
activated.

●Switch on the machine.
●Press the TE/Speed key twice to call up the parameter input function.
●Select the parameter "760" by pressing the corresponding +/- key.
No
●Press the corresponding +/- key to set the number of remaining stitches, which can still
be sewn after recognition by the bobbin thread control function.
The selected value is multiplied by 10* or 200** and the result is the number of stitches.
Example display 5 x 200** = 1000 stitches. The setting depends among other things on
the thread strength.
●If the TE/Speed key is pressed, the value is taken over and the machine changes into the
sewing mode.
The bobbin thread rest counter can only be used, if parameter "660" is set at
value "1" or "2".
*If for parameter 660 the value is "1", the multiplier is 10
** If for parameter 660 the value is "2", the multiplier is 200

2.02 Programmed sewing
In programmed sewing 99 programs, each with 9 seam segments and 999 stitches, can be
programmed.
The seam segments can be programmed by entering the number of stitches or by using the
"Teach" function (sewing a seam segment).
Fixed programs are used for the quick and convenient production of seams with a different
number of stitches.
After switching on the machine and selecting the programmed sewing mode with the PM
key, the display appears for selecting program number, seam section and the number of
stitches.
