Operation of LZE-V Shifts Setup > Machine > Shifts 5.8.2 Shift system – Enable external shift cycles if the machine central unit provides this information. – It is therefore possible to set up to 7 different shift cycles manually. Therefore determine the shift cycle per day (2 column).
Operation of LZE-V 5.9 Group Administration Setup > Production Groups With LZE-V it is possible to run up to two different production groups on one machine (only for double sided machines). The range of the production groups can be either one machine side or the entire machine. The rotor range of a group can be selected by enlarging or reducing the size of the transparent window on the rotor overview.

Operation of LZE-V 5. An article with assigned clearer settings must be selected from the 10 active articles of the LZE-V. More details for article selection can be found in the chapter “Article Administration”. 6. For a lot change tick the box of the production group that you want to change and confirm.
The three buttons are used for article archive organization / loading the default values / loading the original values. Advanced menu should only be entered by Loepfe service technicians. Activate the different yarn clearer functions by ticking the box next to the specific clearer channels.
Operation of LZE-V 5.11 Article Settings Setup > Articles The major clearer channels can be set by the selection of classes within the clearer matrix through the touch screen. Each class is limited by a length and deviation limit which both can be set individually within certain limits. A red class is activated for clearing, a yellow one can be selected in addition.

This will reduce dust locks. Always clean when a rotor is stopped for dust lock (both sensor LEDs on). Only use the cleaning swabs With? 7.4.2 from LOEPFE (part no. 16964900). Use it either dry or dampened with optical lens cleaner. How? 7.4.3 Drag the soft tip of the cleaning stick a few times through the measuring slot.
Inspection and Maintenance 7.5 Diagnostics Service > Diagnostics Versions 7.5.1 Versions The submenu displays a summary of the installed software package, as well as the included LZE-V, SE and SH software versions. In addition it also shows a summary of the software actually installed on the SE boards and the sensing head.
Inspection and Maintenance Tests 7.5.3 Tests are used to check the communication between the LZE-V, the SE and the sensing heads as well as the communication of the interface connections between the SE and the machine section electronics. When starting the test, each rotor of the chosen rotor range will go into a forced lock one by one starting with the smallest rotor number.
Troubleshooting 8.1 Hardware Locks / Recommended Action LOEPFE YM 1N1 / 3N1 has a built-in diagnostic function. Technical problems are indicated by means of hardware locks. Hardware locks can only be cancelled on the LZE-V GUI. Hardware failures can have a severe influence on yarn quality!
Troubleshooting 8.2 Analysis of rotors with Rotors with unusual behavior, such as too many cuts, increased Q, F or P data etc., are an indication that something at this rotor position is different unusual behavior from the rest of the machine. This unusual behavior can have various causes, such as differences in the applied sliver, the spinning components or malfunc- tions of the clearer.
