8.20 Light Barrier

 Light barrier module LSM002 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 with or without control panel Parameter

Light barrier On/Off 009

Function with control panel V820/V850

Light barrier covered/uncovered On right-hand arrow On Key 3

Light barrier uncovered/covered On left-hand arrow On

Light barrier Off both arrows Off

8.20.1 Speed after Light Barrier Sensing

Function with or without control panel Parameter

Speed after light barrier sensing (n5) 114

8.20.2 General Light Barrier Functions

Function with or without control panel 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/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.

The light barrier compensating stitches can be programmed and varied using the above parameters directly on the control or

on a connected control panel. For fast operator information (HIT) when using the V820/V850 control panel, the value of

the function switched on by means of key 3 can be displayed for approx. 3 seconds. During this time, the value can be

varied directly by pressing key + or -.

8.20.3 Reflection Light Barrier LSM002

Sensitivity setting:

Set minimum sensitivity depending on the distance between light barrier and reflection area (turn potentiometer as far as

possible to the left).

 Potentiometer directly on the light barrier module

Mechanical orientation:

Orientation is facilitated by a visible light spot on the reflection area.
