– Ensure the protection class (see Appendix A “Technical
data”).
– Via the left-hand end plate, the CDVI is supplied with com-
pressed air (connections (1), (12/14)), the exhaust air is
removed (connections (3/5), (82/84)) and with the CDVI-
MP the terminal is supplied with voltage.
– Via the right-hand end plate the CDVI can also be sup-
plied with compressed air (connection (1)) and the ex-
haust air can be removed (connection (3/5)). The right-
hand end plate variant determines whether the CDVI is to
be operated with internal or external pilot air supply:
– Right-hand end plate type CDVI5.0-EPR
for supplying the valves with internal pilot air,
branched from the overall supply (compressed air
channel (1)).
– Right-hand end plate type CDVI5.0-EPR-S
for supplying the valves with external pilot air, pres-
sure regulated separately (3 ... 8 bar). The external
pilot air is supplied via connection (12/14) on the left-
hand end plate.
1.3.3 Valves
Note
The valve positions are intended for Festo valves and may
be fitted only with the valves approved of by Festo.
The valve positions must not be used for any other pur-
pose.
The components on the valve positions are marked with
identification codes. With these codes you can ascertain the
equipment fitted on your CDVI. The codes are printed on the
covers of the valves or on the blanking plate. An overview of
the valves can be found in Appendix A.
