7. Control unit and operating panel
IMPORTANT !
This manual covers only those key functions and parameter
changes available to the operator.
For a more detailed description of the control unit please
consult the motor manufacturer’s current Operating manual
(supplied).
The operating panel is used to program the control unit and to set seam functions.
Depending on the nature of the job, sewing may be executed manually or by seam
programming.
For various sewing tasks seams can be programmed for which the functions (starting
and finishing lock-stitches, stitch counting etc.) and parameter v alues (number of
stitches, seam length, speed of rotation etc.).
Entry is carried out in programming mode.
The parameters and the values assigned are displayed.
The seam programs are not lost even if the sewing machine is switched off (battery
buffer).
In order to avoid the inadvertent alteration of pre-set functions operation is divided into
several l evels (operator, technician, fitter).
The operator (seamstress) can program it directly.
On the other levels access is contingent on the entry of a code number.
RESET
If the control unit is hopelessly misadjusted, this function allows the technician to reset
all adjusted values to their default (ex-works) setting.
This function is described in the Installation Instructions.
