3 Products and functions
3.1 Product description
The yarn clearer system is used to clear yarn faults and foreign matter, and for quality monitoring during
winding. It is installed on winders from various manufacturers. Yarn faults are detected by means of a dual
measurement system. The yarn clearer system can be combined with the MillMaster TOP data evaluation
and administration system.
3.1.1 Loepfe Central Unit (LZE)
LZE-6 central unit
The central unit consists of the following components:
nComputer
nTouchscreen display
nUSB port
nYarn clearer software
Functions:
nCommunication with sensing heads
nYarn clearing control and monitoring
nProcessing, logging and storage of process and quality data
3.1.2 Spindle adapter
The spindle adapter (SA) is the interface between the central unit, the sensing heads and the spindles to
supply power to the sensing head and adapt the connections.

4.1 Installation
DANGER
Electric voltage hazard
Contact with live parts poses an imminent risk of fatal injury.
4All electrical work on a yarn clearer system must be performed exclusively by
qualified personnel specifically authorized to do so.
4Work on electrical components may only be performed when the system is
switched off and disconnected from power.
DANGER
Danger due to electric shock
Touching live components and electrical connections can lead to serious physical
injury or death.
4Disconnect the unit from the power supply before performing maintenance or
repair work.
4Disconnect the device from the power supply before removing the covers or
opening the side panels.
WARNING
Danger from incorrect installation and operation
Risk of injury and property damage through custom modifications to the yarn
clearer system.
4Only authorized service technicians may perform installation and operation of
the yarn clearer system or individual system parts, or perform upgrades.
WARNING
Working on running machines poses a risk of severe physical
injury.
4Switch off machines and wait until they have come to a complete stop.
4Work on electrical components may only be performed when the system is
switched off and disconnected from power.
4Before installing or performing maintenance on machines, disconnect the
compressed air supply and release the pressure from the machines’
compressed air system.
4Before operating, ensure that all appropriate covers are in place.
