Speed control for the free seam and the seam with stitch counting can be selected using the speed mode.
Parameter 142 = 0 Execution at pedal controlled speed
Parameter 142 = 1 Execution at fixed speed n12, when pressing the pedal forward (position >1)
Parameter 142 = 2 Execution at limited speed n12, when pressing the pedal forward (position >1)
Parameter 141 = 3 Only for the seam with light barrier:
- Automatic execution at fixed speed after having pressed the pedal once.
- The seam end is initiated by light barrier.
- The procedure can be interrupted by heelback (-2).
- If the light barrier is not on, speed as with parameter setting 142 = 0.
The maximum speed is displayed on the control panel after power On and thread trimming and can be varied directly using
key +/-. The setting range lies between the values of parameters 111 and 121.
6.27 Light Barrier
Light barrier module LSM001A is provided and is connected to socket B18.
Moreover, an external light barrier can be connected to socket A/13.
Both light barrier inputs initiate the same function and can be enabled and disabled with the same parameters.
Function on the V810 control panel Parameter

Light barrier uncovered/covered On lefthand arrow above key On
Light barrier Off both arrows Off
6.27.1 Speed after Light Barrier Sensing
Functions Parameter
Speed after light barrier sensing (n5) 114
6.27.2 General Light Barrier Functions
Functions Parameter
Light barrier compensating stitches (for long stitches) (LS) 004
Number of light barrier seams (LSn) 006
Light barrier compensating stitches (for normal stitches) (cLS) 010
Light barrier sensing uncovered/covered (LSd) 131
Start of sewing blocked/unblocked with light barrier uncovered (LSS) 132
Light barrier seam end with thread trimming On/Off (LSE) 133
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
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 on the V810/V820
control panel.
For fast operator information (HIT) when using the V820 control panel, the value of the function enabled using key 3 can
be displayed for approx. 3 seconds. During this time, the value can be varied directly by pressing key + or -.
