Control Box Operation
Main Control Box:
The front of the main control box has an Auto/Manual Switch, a Manual Ruffle
Pushbutton, an Unwinder Reverse Switch, a Fuse Holder, and 6 Thumbwheels. On the
back is the power entry socket and an on/off switch. Be sure the on/off switch is always
on.
Note: The on/off switch only switches one line and does not make the box
safe to work on. Always disconnect the main power cord before servicing the
control box.
The Auto/Manual Switch turns on the
automatic ruffling cycles for the corners. When
this switch is in Manual, the ruffling is disabled
and the machine will only sew, trim, and foot lift.
The Manual Ruffle pushbutton turns on one
ruffle cycle and also functions as the Reset button
for the automatic cycle. Pushing this button once
will turn on the ruffle cycle. Pushing it a second
time will reset the automatic program and cause
the ruffle hardware to reset and go to its "Home"
position. Use this button to reset the ruffler after
adjusting the ruffle size.
The Unwinder Reverse switch controls the
direction of the Unwinder reel. Use to set the
proper direction depending on how the gusset
material is wound. The Unwinder will run whenever the Treadle is not in the neutral
position (either sewing or healed back) and the Loop Eye is seeing the gusset material.
The Fuse Holder fuses the entire machine. Replace the fuse with a 5A Slow Blow
250v as necessary.
Thumbwheels
The first Thumbwheel on the left controls the on time of the Unwinder motor. It
controls how long the motor runs after the Loop Eye has seen the gusset material. It is
usually set to 9.
The second Thumbwheel controls the sewing speed of the sewing head during
ruffling. Each increment is approximately 100 rpm. The normal setting is "6".
The third and fourth Thumbwheels together make up the Stop count for the
corners. This is the stitch count (00-99 stitches) from when the front eye uncovers until
the sewing stops in the corner to start the ruffling cycle. This should be adjusted to stop
the panel so that when the corner turn is finished the right edge of the panel is flush
against the edge guide. If, after turning the corner, the right edge of the panel is to the
left of the edge guide, decrease the stitch count to stop the panel sooner. If, after turning
the corner, the right edge of the panel is to the right of the edge guide, increase the stitch
count to stop the panel closer to the foot.
The fifth Thumbwheel sets the number of ruffles to be sewn in each corner. Adjust
this setting along with the ruffle size to achieve desired corner finish.
The sixth Thumbwheel sets the number of stitches sewn in each ruffle and is
adjusted according to the ruffle size. There should be enough stitches to sew to the folded
edge of each ruffle.
