3. Installation
Separator plates
3-12
Note
With more than 2 pressure zones:
Ensure that there is a corresponding pneumatic supply
port for each pressure zone.
Conversion of the CDVI to 2 to 9 pressure zones is described
in chapter 5 "Cleaning, maintenance and conversion."
Note
All the valves of the CDVI are supplied with pilot air from a
central source. The pilot air is either branched internally
from channel (1) or supplied externally via port (12/14).
This also applies if the CDVI has several pressure zones.
With internal pilot air supply and pressure zone separation
of channel (1), observe the following:
– The internal pilot air supply is branched in the right end
plate from channel (1). The operating pressure in the
right zone must therefore lie between 3...8 bar. In the left
and centre pressure zones the operating pressure may
lie between -0.9...10 bar and 3...10 bar, depending on
the valves that are used (see Appendix A "Technical
data").
For the CDVI the following separator plates are available for
creating pressure zones:
