Intended use
The CDVI valve terminal with direct fieldbus connection
described in this manual is intended exclusively for use as
station on the DeviceNet fieldbus.
This CDVI valve terminal has been certified by the ODVA.
Thevalveterminalmaybeusedonlyasfollows:
– As intended in an industrial environment
– In original condition without unauthorized alterations.
Only the conversions or modifications described in the
documentation supplied with the product are permitted.
– In perfect technical condition
The limit values specified for pressures, temperatures, electri-
cal data, torques etc. should be observed.
If conventional accessory components such as sensors and
actuators are connected, the specified limits for pressures,
temperatures, electrical data, torques etc. should be ob-
served.
Comply with the regulations of the trade associations and
the German Technical Control Board (TÜV) and the VDE
conditions or corresponding national conditions.
Observe the measures in section 1.4.4 when implementing an
emergency stop function.

1.1 General installation instructions
Warning
Uncontrolled movements of the connected actuators and
uncontrolled movements of loose tubing may cause per-
sonal injury or material damage.
•Before any conversion work on the CDVI-DN, switch off
the following:
– Compressed air supply
– Power supply
•Make sure no control signals from the higher-order con-
troller are present at the solenoid coils.
Note
Observe the CDVI assembly instructions in the “CDVI
pneumatics manual” (CP.BE-CDVI-...) in chapter 2.
The CDVI-DN contains electrostatically sensitive devices.
•Do not therefore touch any electronic components.
•Observe the handling specifications for electrostatically
sensitive devices.
They will help you avoid damage to the electronics.

1. Installation
1-6 Festo P.BE-CDVI-DN-EN en 0805a
Removing
1. Switch off all power supplies (electric voltage,
compressed air).
2. Loosen each of the two mounting screws on the left-hand
end plate by approximately one turn.
3. Now unscrew the two mounting screws completely to
avoid twisting or squeezing the separator plate (seal).
4. Pull off the left end plate.
Mounting
1. Place the separator plate (seal) on the manifold block.
The separator plate must be fitted correctly on the guide
sleeves of the manifold block.
2. Position the left end plate too.
3. Tighten the two mounting screws alternately. Torque:
3.5 Nm (... 4 Nm)
Note
•Make sure the separator plate (seal) is not squeezed on
one side as a result of uneven tightening of the cover
screws.
The requirements of the IP protection class cannot be
fulfilled if a seal is squeezed.
