11 BERNINA Stitch Regulator (BSR) (optional accessory)
The BERNINA Stitch regulator equalizes the stitch length which results of the free movement of the fabric
while free-motion sewing - a sewing technique which grows more and more popular. When free-motion
sewing with the BSR presser foot, every stitch is equally long and the stitch formation is perfectly regular.
As soon as the BSR presser foot is attached and the feed dog is lowered, the selection menu of the desired
mode appears in the display of the machine. The BSR presser foot can be used with sewing straight stitch as
well as zig zag.
The BSR presser foot reacts on the movement of the fabric and therefore controls the speed of the machine
up to the highest possible speed. It can be said: the faster the movement of the material, the higher the
speed of the machine.
If the fabric is moved too quickly, an acoustic signal sounds. The beeper can be activated or deactivated in
the BSR display. The sound of the beeper can also be activated or deactivated in the Setup Program.
11.1 BSR mode 1
The BSR function can be controlled via the foot control or with the button «Start/Stop». Start the BSR mode.
At the BSR presser foot a red light is on. By moving the fabric the machine accelerates. If the fabric isn't
moved, securing in place is possible without pressing an additional button. When working via the foot
control or when using the button «Start/Stop», the BSR mode doesn't stop automatically.
11.2 BSR mode 2
The BSR function can be controlled via the foot control or the button «Start/Stop». The machine starts only
when the foot control or the button «Start/Stop» is pressed and the fabric is moved simultaneously. Without
moving the fabric, the BSR2 modus stops after about 7 seconds. The red light goes off (only when working
with the button «Start/Stop»). When working via the foot control, the red light doesn't go off.
11.3 BSR function with Straight stitch No. 1
This function allows free-motion quilting with straight stitch and a pre-programmed stitch length up to
4 mm. The programmed stitch length is maintained within a certain speed, independent of the fabric
movement.
11.4 BSR function with Zigzag No. 2
The zig zag can be used e.g. for thread painting. The set stitch length will not be maintained when sewing
the zig zag stitch, but the BSR function simplifies the application.
