Proper use 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.
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.

Setting up Setting up Entering the maximum speed ● Switch on the machine. Speed 4000 ● Enter the maximum speed by pressing the corresponding +/- key. Setting the presser foot pressure Speed 4000 The presser foot pressure is adjusted with the sewing speed. The greater the sewing speed, the higher the pressure foot pressure.
Setting up Entering the start and end backtacks Switch on the machine. ● Select the manual sewing mode by pressing the "PM" key. ● Press the TE/Speed key twice to select the input menu for start and end backtacks. ● In the programmed sewing mode it is possible to call up the input menu for start and end backtacks by pressing the scroll key, see Chapter 5.02 Program- med sewing.
Setting up Setting the stitch counting function for the bobbin thread control Switch on the machine. ● Press the TE/Speed key to call up the parameter input function. ● By pressing the corresponding +/- key select the parameter "760". ● Press the corresponding +/- key to set the number of remaining stitches, which can still be sewn after recognition by the bobbin thread control function.
Sewing Sewing In the sewing mode all relevant adjustments for the sewing operation are shown on the dis- play and can be altered directly. Functions can be switched on and off by pressing the key. In this mode a difference is made between manual sewing and programmed sewing. To change from manual to programmed sewing, press the PM key.
Sewing Programmed sewing In the programmed sewing mode 99 programs, each with 9 seam sections and 999 stitches, can be programmed. The fixed programs are used for the quick and easy production of seams with different numbers of stitches. The pedal setting "0" is used to switch to the next seam section. After the machine has been switched on and the programmed sewing mode has been selected with the PM key, the display appears for selecting the program number, seam section and number of stitches.
Sewing Error messages If a fault occurs, the text "ERROR" appears on the display, together with an error code and short instructions. An error message is caused by incorrect settings, faulty elements or seam programs as well as by overload conditions. ERROR PRESS TE-SPEED Correct the error.
