Operation of LZE-V
1N1 / 3N1
On automatic machines the piecing robot will not stop at
this rotor position without unlocking.
Quality, Thick / Thin Sliver and Moiré Locks:
Blocks particular rotors to repeated
Q stops within the set length.
Thick / Thin Yarn Count:
Long diameter deviation. Rotor gets blocked to
remove the defect manually.
Reference Mean:
Rotor gets blocked when the reference mean increases or
decreases more than the set percentage from the average of the machine
side. Check the sensor, yarn, sliver, etc.
CV% Lock:
Relative deviation from the median per side CV%. Rotor gets
blocked to remove the defect manually.
Spectrogram / Ref. Spectrogram:
Blocks particular rotor if the spectrogram
changes more than the set limit for the set length, or deviates from the
referenced machine side.
5.11.2
Foreign Matter (F)
(only 3N1)
Foreign matter clearing is activated by setting classes within the clearer
matrix. The length and deviation limits of the classes can be set individually
within certain limits.
Sensitivity SC / SdC:
sensitivity for short cluster (possible to remove during
piecing).
Sensitivity LC:
sensitivity for long cluster (locks cannot be removed during
piecing. They must be removed manually).
Lock condition:
repeated F stops within the set length. In case of a lock,
check the sliver for contaminants and remove the yarn from the package.
The sensitivity can be set from 1 to 9. Setting 1 is the most sensitive. Choose
9 if you do not want to use the foreign matter cluster.
Locks
are used to block particular rotors that have repetitive quality stops or
longer defects which cannot be removed by the piecer.
The blocked rotors must be unlocked again before the restart of the rotor.
This can be done via LZE-V or the TK button.
