BSR BSR Description BSR (BERNINA Stitch Regulator) Function The BSR presser foot reacts to the movement of the fabric under the foot and controls the speed of the sewing computer up to the maximum speed possible. The following applies: the faster the fabric is moved the higher the speed of the sewing computer. If the fabric is moved too fast an acoustic signal (beep) is heard. The beeper can be turned on or off in the Setup Program or directly on the «BSR» screen. By activating the BSR function the sewing computer sews either continuously at a reduced motor speed (mode 1, standard), or as soon as the fabric is moved (mode 2). As long as the BSR presser foot is illuminated red, adjustments like threading and changing the needle, for example must not be carried out, as the needle will engage while fabric is moved unintentionally! Without fabric feed the BSR mode is turned off after approx. 7 seconds and the red light goes off. Please refer to the Safety Instructions! With Straight Stitch no. 1 This function using a special presser foot allows for free-motion quilting (sewing) using the straight stitch and a pre-selected stitch length (up to 4mm). A regulated set stitch length is maintained within a certain speed, independent of the movement of the fabric. With Zig-zag Stitch no. 2 The zig-zag stitch can be used for thread painting or fabric embellishment. The set stitch length will not be maintained when sewing with the zigzag stitch, but the BSR function simplifies the application. BSR function can be sewn in 2 separate modes of operation ► BSR mode 1 is the active standard ► the sewing computer runs continuously at a reduced motor speed, as soon as the foot control or the StartStop-button is pressed ► moving the fabric under the foot will engage the sewing computer to accelerate ► through the continuous needle movement securing in the same position is possible without pressing an additional button ► touch the button «BSR2» to engage BSR mode 2 ► the sewing computer will only engage if the foot control or the Start-Stop-button is pressed and the fabric is moved simultaneously ► the movement of the fabric determines the sewing speed ► for securing, the «Securing Function» button must be pressed ► touch the button «BSR1» to engage BSR mode 1 When exceeding a certain speed, adhering to regular stitch length cannot be guaranteed. Make sure that the lens on the bottom of the BSR foot is not dirty (fingerprints, etc.). Clean lens periodically with soft, slightly damp cloth. For an even sewing start (one single stitch) the foot control must be pressed and the fabric moved simultaneously. This also applies for sewing points and straight stitching within a round form. If the BSR function is deactivated and later re-activated without the sewing computer being switched off in between, the last selected BSR mode is active. 110
