DANGER
Uncontrolled operation may result in personal injury
and damage to the vacuum pump system.
When using several vacuum pump systems, there is
the danger of confusing them, which can result in
undesired interference into other processes: The
transmission of commands from the wrong hand
terminal for the vacuum pump system may trigger an
uncontrolled response in the vacuum pump system
that the terminal controls.
Every time a vacuum pump system is used with
a hand terminal, it is essential to ensure a
correct match between the two components. Use
the paging function for this purpose (see
Actuating the vaccum pump system, page 29).
Additionally it is possible to use color stickers to
indicate which hand terminal belongs to which
vacuum pump system (see chapter
11. Ordering
information
).
WARNING
Uncontrolled operation may result in personal injury
and damage to the vacuum pump system.
If the wireless connection between the hand terminal
and vacuum pump system is broken, the vacuum
pump system will continue to operate with the cur-
rent settings.
Immediately determine and remove the cause of
the interruption between the hand terminal and
vacuum pump system (chapter 10, page 40).
If you are not able to reestablish wireless
contact, replace the hand terminal back to the
vacuum pump system (chapter 8.1.1, page 23).
The vacuum pump system can also be operated
directly and the ventilation valve and coolant
valve can be opened and closed directly
(chapter 8.2, page 32).
WARNING
Personal injury caused by poisoning or explosion
and damage to the vacuum pump system.
Make sure that no reactive or explosive mixtures
will be produced when ventilating the vacuum
pump system through the air inlet.
