Description of functions
About this chapter
The Description of functions is divided in two levels:
• Basic principles – Basic principles containing a
survey of the function. This text is written with an
italic typeface. The text refers to the diagram
"Basic principles" in chapter "Diagrams".
• Enhanced information – Enhanced information
about the function. Normal typeface is used in this
text. This text refers to the following diagrams in
chapter "Diagrams":
– Pneumatic block diagram
– Electronic interconnection.

charge level is reached (fully charged).
The following applies concerning battery voltage
supply:
• Battery voltage supply is used as soon as the

is in use.
• First battery alarm "Limited battery capacity" is
activated when battery voltage reaches below 23 V
