g) As soon as another parameter number is called up, e.g. example 703, the previously programmed
value of <702> is memorized.
h) With parameter 703 and 710 correction is obtained as described above for parameter 702.
i) Deactivate programming level B (see section 9.1.2 „programming level B“).
10.2.3 Control of the positioning (angle) for thread trimming (NP5 / NP6)
NP5 - end of trimming signal 1 (<705>)
NP6 - start of trimming signal 2 (<706>)
a) Activate programming level B (technician level) (see section 9.1.2 „programming level B“)
b) Set parameter 705
c) Actuate the treadle briefly forward
Reaction: The machine performs a revolution and positions at the indicated <705>.
d) Is the position correct?
When yes, then proceed as g) below.
When no, then the position must be corrected
by turning the hand wheel (when <701> = I) or
via keys L+ or L- (when <701> = II).
e) Activate the treadle forward.
Reaction: The machine performs a revolution and positions at the corrected program value <705>.
f) The position can again be corrected.
If no further correction is needed, then proceed as g) below.
g) Back heel the treadle.
Reaction: The machine rotates to NP2, <705> is memorized, programming (correction of position) is
no longer possible.
h) If the treadle is back heeled then the thread trim procedure will be activated and the machine
performs one revolution.
i) Should parameter <705> be changed again, then the sequence from c) above must be repeated. In
any other event, call up parameter 706 and repeat the sequence from c) above.
j) Deactivate program level B (see section 9.1.2 „programming level B“).
