Low Bobbin - Pfaff powerquilter 1600 User Manual

Low Bobbin

The powerquilter™ 1600 includes a low bobbin
alarm to esti mate how soon the bobbin thread
will run out. This low bobbin capacity is based on
an esti mate of how much of a parti cular thread
can fi t on a bobbin, in combinati on with other
quilti ng factors such as tension, sti tches per inch,
and how much bobbin thread is used to pull up
and ti e off when beginning and ending quilti ng.
To esti mate how much thread is on a bobbin,
place a full bobbin in the machine, press the red
Record butt on "A", and quilt as usual.
When the bobbin runs out, press the top left
butt on to Stop Recording. Note the number that
is indicated under the Bobbin Thread Capacity
"B". Use the "–" butt on to reduce the number
by 15 to 20 so the alarm will sound before the
bobbin runs out. Save the reduced number as
one of the Bobbin Thread Capacity Presets "D".
Make a note as to which type of thread the
preset represents.
Put a new bobbin with the same thread into the machine and press the New Bobbin butt on "C". Then
press the Alarm butt on "E"� As you quilt, the remaining bobbin thread value will esti mate how much
thread remains on the current bobbin, and when you reach the capacity value, an alarm will sound
warning that the bobbin is nearly out of thread.
When operati ng in manual mode, the low bobbin functi on assumes sti tching at approximately the last SPI
setti ng on the regulated screen. If the SPI setti ng was below 8 sti tches per inch, the functi on will assume
you will quilt at 10 sti tches per inch. It is advisable therefore to set the sti tches per inch, on the regulated
screen before you change to manual mode.
Three Bobbin Thread Capacity preset values can be stored – one for each of three diff erent types of
thread. Simply go through the record process with a full bobbin of that type of thread and then store
the capacity as a preset. Press the corresponding preset butt on "F", insert a full bobbin with that type of
thread, and press New Bobbin butt on to start.
