9.1.6.4 Fault - Extraction status menu
The extraction status menu also indicates the fault. There may be a problem within the oil itself (debris
or dirt) or in the air hose system (leak) that is not identifiable as oil contamination in the unit or the
device’s protective hood. The red mark in the following figure highlights the area where the fault mes-
sages are displayed in the event of a fault.
Extraction status menu with fault message
The area designated for the fault message is too small to display the possible cause of the fault in text
form. The fault message is shown in short form. The following table reveals the possible reasons for
the occurrence of a fault. Given that numerous components are involved in the extraction cycle, an
analysis of the fault cycle's cache data for the purpose of fault detection is inevitable.
