11.17 Disabling of Flip-Flop Functions at the Seam End
Function
with
or
without
control panel
Parameter
Disabling of flip-flop functions at the seam end On/Off
(FFm)
183
Determine by means of parameter 183 whether signals M6 and/or M10 shall be switched off at the seam end. If 183 = 0,
the signals can be switched off only by means of the appropriate keys.
Parameter 183 = 0
Signal M6 (flip-flop 1) and signal M10 (flip-flop 2) are not switched off at the seam end.
Parameter 183 = 1
Signal M6 (flip-flop 1) is switched off at the seam end.
Parameter 183 = 2
Signal M10 (flip-flop 2) is switched off at the seam end.
Parameter 183 = 3
Signal M6 (flip-flop 1) and signal M10 (flip-flop 2) are switched off at the seam end.
11.18 Bobbin Thread Monitor
Function
with
or
without
control panel
Parameter
Bobbin thread monitor 0 = Off / 1 = with stop / 2 = without stop / 3 = with stop and
(rFw)
030
start blockage after thread trimming
Number of bobbin thread monitor stitches
(cFw)
031
For bobbin thread monitor operation a number of stitches depending on the length of the bobbin thread is preset by means
of parameter 031. After the execution of these stitches the drive stops and a visual signal appears on the display. If a control
panel is connected, an audible signal is also issued if parameter 127 is set accordingly. This signals that the bobbin thread
will run out. After pressing the pedal again, the seam can be continued and the thread can be trimmed. After inserting a full
bobbin and pressing the ENTER key, a new sewing operation can be started.
Enable bobbin thread monitor:
!
Set parameter 030 to "1...3".
!
Input the desired maximum number of stitches in parameter 031 (input value x 100 = number of stitches,
e. g. 80 x 100 = 8000).
!
For starting the counter set the A or B key at “19” by means of parameter 293 or 294.
!
When using a control panel, an audible signal can also be enabled by means of parameter 127.
!
Start the sewing operation.
Bobbin thread monitor in operation:
!
Parameter 030 = 0:
Bobbin thread monitor is off.
!
Parameter 030 = 1:
The drive stops after the stitch counter has run out. The message "A7" appears on the control,
and the bobbin thread monitor symbol blinks on the V810/V820 control panel, respectively. There will be an audible
signal if a V820 is connected and parameter 127 is set at “1“.
!
Parameter 030 = 2:
The drive stops after the stitch counter has run out. The message "A7" appears on the control,
and the bobbin thread monitor symbol blinks without stopping automatically on the V810/V820 control panel,
respectively. There will be an audible signal if a V820 is connected.
!
Parameter 030 = 3:
The drive stops after the stitch counter has run out. Thread trimming is possible with pedal in
pos. –2. The start is blocked. The message "A7" appears on the control, and the bobbin thread monitor symbol blinks
on the V810/V820 control panel, respectively. There will be an audible signal if a V820 is connected and parameter
127 is set at “1“.
!
Parameter 030 = 4:
Function as with parameter 030 = 1, but remaining stitches will be displayed.
!
Parameter 030 = 5:
Function as with parameter 030 = 1, but remaining stitches will be displayed.
!
Parameter 030 = 6:
Function as with parameter 030 = 1, but remaining stitches will be displayed.
Getting the bobbin thread monitor ready for operation:
!
Insert a full bobbin.
!
Press the selected external key, or the appropriate key on the connected control panel (8 key on the V820).
!
Set counting to the value determined by parameter 031 and start it.
!
The symbol stops blinking, and the message "A7" on the control will be switched off after trimming.
