11.23 Overlock Machine Functions (Mode 7)
11.23.1
Chain Suction Signal
The chain suction signal can be preselected for start and end counting, respectively, by means of the
S2
key on the control
and the
1
key on the V810/V820 control panel. If chain suction and tape cutter are switched off at the start of the seam, the
respective counts will be suppressed. But they will be performed at the seam end.

There are various setting possibilities with the following parameters in the overlock mode (mode 7).
Parameter 018 = 0
Sequence with stop.
Parameter 018 = 1
Sequence without automatic stop at the seam end. When the command “run” is given, the drive
runs at the preselected speed. The program switches to the next start of a seam without issuing
signals M1/M2, when the pedal is in pos. 0 (neutral) or the light barrier is covered.
Parameter 018 = 2
Sequence as with setting 1. But signals M1/M2 will be issued when the pedal is in pos. 0
(neutral), and the program switches to the next start of a seam.
Parameter 018 = 3
Sequence as with setting 1. But signals M1/M2 will be issued when the pedal is in pos. -2, and
the program switches to the next start of a seam. Intermediate stop and sewing foot lifting with
pedal in pos. –1 is possible.
Parameter 022 = 0
The chain suction signal at the seam end is disabled after count c2.
Parameter 022 = 1
The chain suction signal at the seam end remains on until pedal in pos. 0 (neutral).
Parameter 022 = 2
C
hain suction until the drive is at standstill and the switch-off delay (parameter 237) has
elapsed. The switch-off delay will be disabled whenever a new seam is started.
Parameter 025 = 0
Start counting for thread tension release at the start of the seam.
Parameter 025 = 1
Start counting for thread tension release when the light barrier is covered.
