Function Of The Supplementary Thread Tension In Relation To The Stroke Adjustment And The Speedomat For Subclass 669-180312 - Duerkopp Adler 669 Instruction Manual

6.2.2 The influence of the stroke adjustment on the supplementary thread tensioner and the Speedomat,
for subclass 669-180312
Button 1 (see Chapter 6.14) on the machine's row of buttons can be
used to activate or deactivate the supplementary thread tension at any
time. The parameter F-255 must be set to "7" for this to work.
Parameter Max. stroke

F-197 = 0 1
F-197 = 1 0
F-197 = 2 1 (*)
F-197 = 3 0
(*) If the stroke adjustment (max.) is activated via the knee switch and
the HP speed (from parameter F-117) has been reached by the
"Speedomat", then the supplementary thread tensioner is automatically
activated.
0 = Supplementary thread tension closed mechanically
1 = Supplementary thread tension opened mechanically
·
If the supplementary thread tensioner is closed, the state of the
stroke adjustment does not change.
·
If the machine is turned off, the supplementary thread tension
remains at its previously set state.
