 After sensing the seam end, the compensating stitches are counted at light barrier speed.
 Suspension of the procedure with pedal in pos. 0 (neutral). Interruption of the procedure with pedal in pos. -
2.
 The thread trimming operation can be disabled using parameter 133, regardless of the setting of key 5 on
the V820/V850 control panel. Stop in the basic position.
 Programming of max. 15 light barrier seams depending on the setting of parameter 006 with stop in the
basic position. Thread trimming after the last light barrier seam.
 Light barrier sensing uncovered or covered at the seam end can be selected using parameter 131.
 Start blockage with light barrier uncovered programmable using parameter 132.
 Speed selection pedal controlled / n5 during the light barrier compensating stitches using parameter 192.
The light barrier compensating stitches can be programmed and varied using the above parameters directly on
the control or on a connected V810/V820/V850 control panel.
For fast operator information (HIT) when using the V820/V850 control panel, the value of the function switched
on using key 3 can be displayed for approx. 3 seconds. During this time, the value can be varied directly by
pressing key + or -.
When using the V820/V850 control panel, direct access by means of the function key (key 9) is possible.
