If the CDVI is intended for internal pilot air supply, port
(12/14) on the left-hand end plate must be sealed with
a blanking plug.
External pilot air supply
If the operating pressure of the CDVI lies below 3 bar
or above 6 bar, pilot control of the solenoid coils must
be operated with an external pilot air supply.
Note
•
Use regulated external pilot air (3...8 bar). Then reliable,
trouble-free operation of the CDVI is possible, e.g. even
with fluctuating operating pressure.
•
The external pilot air supply is supplied centrally for
all solenoid coils via the pilot port (12/14) on the left
end plate. This also applies when the CDVI is operated
with different pressure zones (see Fig. 3/3 and Fig. 3/4).
•
Set the pilot pressure of the external pilot air supply to
correspond to the operating pressure with which these
valves are operated (see Appendix A, Fig. A/1).
3.4.2
CDVI with pressure zone separation
The CDVI can be equipped with 2 to 9 pressure zones. There is
not intended to be a pressure zone separation within the mani-
fold block. The CDVI must be fitted with at least one expansion
block in order that two pressure zones can be created.
