1.3.1 In-line valve manifolds

There are two types of in-line manifold blocks on the CDVI:

– The manifold block has 4 or 8 valve positions. Each CDVI

consists of at the most one manifold block, i. e. no further
manifold blocks can be used for additional valve posi­tions.

– The expansion blocks (2-valve or 1-valve expansion block)

are available in four different versions:

– Standard version without power supply

– Version with pneumatic supply connection

– In addition, on the CDVI with fieldbus connection:

– Version with electrical power supply

– Version with pneumatic supply connection and

electrical power supply

Both versions provide 1 or 2 valve positions. A maximum of
8Mo-expansionblocksor4Bi-expansionblockscanbe
mounted to one manifold block. Mixed components are per­missible.

Valves and blanking plates are fitted on the in-line valve mani­folds. The working lines (2) and (4) are provided for each
valve position on the in-line valve manifolds. Each valve posi­tion supports triggering 2 solenoid valves (only applies to
manifold blocks, otherwise depends on expansion). The end
plates form the termination. The in-line valve manifolds pro­vide the following connections:

Festo P.BE-CDVI-EN en 1202e

– Common channels for supply and exhaust air for:

– Compressed air supply to the valves

– Removal of the exhaust and pilot exhaust air at the

valves.

– Electric signals from all solenoid coils.

1.3.2 End plates

Festo P.BE-CDVI-EN en 1202e

The CDVI possesses as mechanical termination of the terminal
both a left and a right-hand end plate. These end plates fulfil the
following functions:

1-9

1. O verview of components

– 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 CDVI­MP 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 ex­haust air can be removed (connection (3/5)). The right­hand end plate variant determines whether the CDVI is to
be operated with internal or external pilot air supply:

1.3.3 Valves

– 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, pres­sure regulated separately (3 ... 8 bar). The external
pilot air is supplied via connection (12/14) on the left­hand end plate.

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 pur­pose.

1-10

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.

2.1 Mounting the valve terminal

Warning

Uncontrolled movements of the connected actuators and
uncontrolled movements of loose tubing can cause injury
to persons and/or damage to property.

•

Make sure that the higher-order controller has not sent
control signals to the solenoid coils.

•

Before carrying out conversion work on the CDVI, switch
off the following:

– The compressed air supply
– The power supply

Note

Handle all the components of the CDVI with great care.
Note especially the following:

– Avoid an offset between the components, otherwise

the protection class requirements may no longer be
fulfilled (see Appendix A, “Technical data”).

– Components must be screwed without offset and

mechanical stress. Screws must be fitted accurately

(otherwise threads may be damaged)
– Observe the specified tightening torques.
– Make sure that the connecting surfaces are clean

(avoid leakage and contact faults).
– Avoid operating the CDVI in the resonant range.

Note

If you do not use the spacer bolts from Festo, note the
following:

– Make sure that there is a gap of at least 90 mm around

the CDVI, e.g. by means of mounting profiles or a section
cut out of the mounting surface, so that the tubing is not
bent.

– Make sure that there is a good conductive connec-

tion between the mounting profile and the earthed
mounting surface.

– Use the M6 mounting holes in the manifold block if you

wish to mount the CDVI on a wall (thread depth 9.5 mm).

3.1 Compressed air preparation

Note

Unfiltered or incorrectly lubricated compressed air will
reduce the service life of the valve terminal.

3.1.1 Operation with unlubricated compressed air

Note

T oo much residual oil content in the compressed air will
reduce the service life of the valve terminal.

– If bio oils are used (oils based on synthetic esters or nat-

ive esters, e.g. rapeseed oil methylic ester), the residual
oil content must not exceed max. 0.1 mg/m

3

(see ISO

8573-1 class 2).

– If mineral oils are used (e.g. HLP oils to DIN 51524 Part 1

to 3) or corresponding oils based on polyalphaolefin
(PAO ), the residual oil content must not exceed 5 mg/m
(see ISO 8573-1 class 4).

This avoids operative malfunction of the valves.

Excessive residual oil is not permissible irrespective of the
compressor oil, as otherwise the basic lubrication will be
washed out with time.

3. Installation

3.1.2 Operation with lubricated compressed air

Operate your system with unlubricated compressed air if
possible. This will prevent pollution of the environment.
Festo pneumatic valves and actuators have been designed
so that, if used as intended, they will not require additional
lubrication and will still achieve a long service life.

Caution

Operation with lubricated compressed air will cause the
life-time lubrication, which is necessary for unlubricated
operation, to be “washed out”.

Note the following instructions if lubricated compressed air
must be used.
The compressed air prepared with the compressor must
correspond in quality to unlubricated compressed air. If poss­ible, do not operate the complete system with lubricated com­pressed air . If possible, always install the lubricators directly in
front of the consuming actuator.

Caution

Incorrect additional oil and too much residual oil content in
the compressed air will reduce the service life of the valve
terminal.

– Use Festo special oil OFSW-32 or the other oils listed in

the Festo catalogue (conforming to DIN 51524-HLP32,
basic viscosity 32 CST at 40°C).

– The additional lubrication must not exceed 25 mg/m

3

(ISO 8573-1 class 5).

– Check that the lubricator setting is correct (see sub-

sequent section)

Festo P.BE-CDVI-EN en 1202e

This avoids operative malfunction of the valves.

3-5

3. Installation

Setting the lubricator: with the machine running (typical operating status) 0.2 to

max. 1 drop/min. or 0.5 to 5 drops/1000 l air.

Checking the setting: the procedure described below can be used for checking the

setting of the lubricator.

Procedure:

•

Check the service units for condensate and lubricator
setting twice per week.

1. Ascertain the actuator which is furthest from the lubricator.

2. Ascertain the valve terminal which controls this cylinder.

3. Remove the silencer, if fitted, from port (3/5).

4. Hold a piece of white cardboard 10 cm in front of the ex­haust port.

5. Let the system run for a short period.

– There must be only a slight yellow colouring on the card-

board. If oil drips out, this is an indication that too much
oil has been used.

Another indicator of over-lubrication is the coloration or the
condition of the exhaust air silencer. A distinctly yellow col­ouring of the filter element or drops of oil on the silencer indi­cate that the lubricator setting is too high.

3.2 General instructions on installation

Warning

Sudden unexpected movements of the connected actuat­ors and uncontrolled movements of loose tubing lines can
cause injury to human beings or damage to property.

Before carrying out mounting, installation and mainten­ance work, switch off the following:

– Compressed air supply
– Operating and load voltage supplies.

Pay attention to the following:
The components of the valve terminal contain electrostatically
sensitive elements. The components will be damaged if you
touch the contact surfaces of the plug connectors or if you do
not observe the handling specifications electrostatically
sensitive components.

3.3 Laying the tubing

If elbow connectors or multiple distributors are used,
the airflow will be reduced slightly .

Connecting Proceed as follows:

1. Push the tubing as far as possible into or over the tube
coupling of the threaded connector.

2. Tighten the clamping screw 1 or, if applicable, pull the
locking ring 2 over the tube coupling.

3. Seal connections that are not required with blanking
plugs 3.

4. For better system clarity, bundle together the installed
tubes with:
– tubing straps or
– multi-tube holder

Disconnecting Proceed as follows:

Warning

Pneumatic tubing that is under pressure can execute un­controlled movements when being dismantled, causing
injury to persons. Carry out the following steps before dis­connecting the pneumatic tubing on the CDVI valve termin­al:

•

Switch off the compressed air supply.

•

Make sure that all pneumatic tubing is pressureless.

•

Exhaust all actuators controlled by valves which are
closed in normal or mid-positions.

1. Mark all pneumatic tubing.

2. Loosen the clamping screw 1 of the fitting or, if applic­able, press down the locking ring of the fitting 2 e.g.
with a Festo QSO releasing tool.

3.4 Notes on installing the CDVI

3.4.1 Pilot control of the solenoid coils (pilot air supply)

Note

– Operate the CDVI whenever possible with unlubricated

pilot air (port (12/14)). Otherwise observe the instruc­tions in the section “Compressed air preparation”.

– In the case of CDVI with internally branched pilot air, the

above-mentioned instruction applies also to the supply

air (port (1)).
The pilot air is supplied centrally to all valves of the CDVI.
– Therefore, operate the valve terminal either with intern-

ally branched or externally supplied pilot air .
This will ensure reliable operation of the valve terminal.

Internal pilot air supply

If the operating pressure of the CDVI is between 3 ... 8 bar,
you can operate the pilot control of the solenoid coils with an
internally branched pilot air supply.

Note

•

Internal pilot air supply is branched centrally from sup-

ply port (1) in the right end plate for all solenoid coils.

This also applies when the CDVI is operated with several

pressure zones (see Fig. 3/3 and Fig. 3/4).

3-10

Festo P.BE-CDVI-E N en 1202e

3. Installation

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 mani­fold block. The CDVI must be fitted with at least one expansion
block in order that two pressure zones can be created.

Festo P.BE-CDVI-EN en 1202e

3-11

3. Installation

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”).

3.4.3 Operating the CDVI with vacuum/low pressure

3-16

Note

The valves with ident. code H, K and N (2x3/2-way valves)
are not permitted for operation with vacuum/low pressure.
A pneumatic spring takes over resetting these valves to the
normal position. This spring is operated with the operating
pressure (channel (1)). An operating pressure of at least 3
bar is required for resetting the valve.

•

Operate these valves in a separate pressure zone.

•

The operating pressure for this pressure zone must be
set in accordance with the diagram in appendix A,
Fig. A/1 .

Thefollowing requirements must be fulfilled so that you can
operate the CDVI at the supply port (1) with vacuum or low
pressure between -0.9...3 bar:

Festo P.BE-CDVI-E N en 1202e

3.5 Connecting the CDVI

3.5.1 Connecting the pneumatic lines

In the case of connecting plates fitted with blanking plates,
seal the working lines (2) and (4) with blanking plugs or
threaded blanking plugs to prevent dirt from entering.

For optimum efficiency of your terminal, the compressed air
supply and the exhausting should take place in the following
cases via the left and right-hand end plates:

Compressed air or
vacuum via port

Exhaust via port

3-18

– Onvalveterminalswithmorethan10valves(nominal

supply pressure 6 bar)

– On large capacity actuators:

Festo P.BE-CDVI-E N en 1202e

3. Installation

Caution

Larger actuators or actuators operated simultaneously
(e.g. cylinders) can create a back pressure in the exhaust
duct of the valve terminal. The size of this back pressure
depends on the capacity of the ducted exhaust tubing.
This may lead to malfunctioning of the CDVI.

•

In this case, exhaust the CDVI via ports (3/5) on both
end plates and, if necessary, on the expansion block.

•

In order to avoid interactions with adjacent valves,
valves on expansion blocks can be separated by means
of a separate exhaust duct (3/5).

Note

Under certain circumstances, excess pressure can build up
under the valve covers of the CDVI. This pressure is re­duced via the pressure compensation hole in the manifold
block.

•

Do not on any account plug the hole for the pressure
compensation.

•

Remove the excess pressure with ducted tubing. Do not
use any non-return valve in the line.

Note

Some ports have been covered with adhesive transparency
as protection against contamination.

•

Remove all adhesive transparencies from the ports.

•

Seal the following if not used:
– unused valve positions with blanking plates
– working ports (2), (4) with blanking plugs or plugs for

QSF plug connectors.

Warning

•

Use for the electrical power supply only PELVcircuits in
accordance with IEC/DIN EN 60204-1 (Protective Extra­Low Voltage, PELV).
Also comply with the general requirements for PELV cir­cuits in accordance with IEC/DIN EN 60204-1.

•

Use only powersources that guarantee reliable electrical
isolation of the operating voltage according to IEC/DIN
EN 60204-1.

By the use of PELV circuits, protection against electric shock
(protection against direct and indirect contact) is guaranteed
in accordance with IEC/DIN EN 60204-1 (electrical equipment
of machines, general requirements).

Note

Check within the framework of your EMERGENCY STOP
circuit, to ascertain the measures necessary for putting
your machine/system into a safe state in the event of an
EMERGENCY STOP (e.g. switching offthe operating voltage
for the valves and output modules, switching off the com­pressed air).

Note

Due to energy stored in the input circuitry of valve termin­als, there may be a delayed reaction of the valves when the
load voltage is switched off. Take this into consideration,
e.g. as follows:

3-22

– Detect that the load voltage has been switched off by

means of an input signal in the controller.

– Block the control signal for the valves by locking the out-

put signal with the input signal “Load voltage”.

Earthing the CD VI

Note

Interference from electromagnetic sources.

•

Earth your CDVI. Make sure that there is a conductive
connection (low impedance, short cable with large cross
section) between the CDVI and the earth potential.

3.6 Address assignment of the valves

Detailed instructions on addressing CDVI with DI connection
“DeviceNet” can be found in the electronics manual
P.BE-CDVI-DN-...

The CDVI occupies 16 or 24 addresses, depending on the
number of valve positions, irrespective of the types of valves
fitted. This enables the CDVI valve terminal to be extended at a
later date without the need to shift the addresses.

– Addresses should be allocated in ascending consecutive

order.

– Counting begins on the CDVI from left to right, but on

the individual valve positions from right to left.

Festo P.BE-CDVI-EN en 1202e

– A valve position on the CDVI valve terminal always

occupies 2 addresses, even if it is only fitted with a
blanking plate.

3-23

3. Installation

– In the case of valves with two solenoids coils, solenoid

coil 14 occupies the less significant address and solenoid
coil 12 occupies the higher-value address.

– In the case of valves with only one solenoid coil, the

higher-value address remains unused.

The following diagram shows the addressing sequence using
the example of the CDVI with 9 valve positions.

4.1 Instructions on commissioning

4.1.1 Before commissioning

•

Switch off the power supply before connecting or discon­necting plugs (otherwise this could lead to functional
damage).

•

Commission only a valve terminal which has been fitted
and wired completely.

•

Make sure that there is a sufficient supply of fresh air
(cooling) for the following operating conditions:
– When the maximum number of valves are fitted
– When the maximum operating voltage is applied
– When the solenoid coil is constantly under stress

•

Please observe the following instructions on building up
pressure in the overall supply.

4.1.2 Pressure increase in the overall supply

Warning

If the pressure build-up of the pilot air supply is too slow
or delayed, this may cause the actuators to perform
sudden unexpected movements under the following condi­tions:

– When the compressed air is connected via a soft-start

valve (gradual pressure build-up) and

– When there are electric signals (e.g. after EMERGENCY

STOP).

This can cause damage to the machine or system and even
injury to persons.

•

Operate the valve terminal with an external pilot air sup­ply (3 ... 8 bar). Branch the pilot air supply before the
soft-start valve (see Fig. 4/1).

4-4

Festo P.BE-CDVI-E N en 1202e

4. Commissioning

The pilot air must be applied with a pressure of 3 ... 8 bar
immediately after being switched on, otherwise there is no
guarantee that the valve will reverse directly (see diagram).
If the pressure is less than 3 bar, there may be a delay before
the valve reverses, in spite of an electric signal. The gradual
pressure build-up of the overall supply does not affect the
actuator in that case. The actuator would react suddenly
(e.g. a cylinder would extend or retract suddenly, depending
on the valve function).

Commissioning by means of the manual override is described
below.

Warning

Before actuating the MO:
Uncontrolled actuation of solenoid coils can cause the

actuators to perform sudden unexpected movements
which may cause personal injury and material damage.

•

Disconnect the operating voltage supply for the solenoid
coils from the relevant connections on the valve
terminal.

4-8

•

Actuate the MOs only with a blunt object

This avoids unintentional actuation of the valve solenoid
coils and damage to the MOs.

Before switching on the power supply:
During commissioning, manual override functions which

are in the switched state can cause actuators to perform
sudden unexpected movements. These movements can
cause injury to persons and damage to property.

•

Make sure that all manual override actuations are reset
to their basic positions.

You will thereby avoid undefined switching states of the
valves.

4. Commissioning

Procedure:

Warning

Before testing the valve-actuator combination:
– Make sure that nobody is in the danger zone.

Note

A valve which has been switched by an electric signal (in
switch position), cannot be reset to the normal position by
actuation of the manual override. The electric signal is
dominant in this case.

•

Reset the electric signal before actuating the manual
override.

1. Switch on the compressed air supply.

2. Check the functioning and effect of each valve-actuator
combination by actuating the relevant manual override.

3. Make sure that all valves are in the normal position before
commissioning the valve terminal.

4. Switch off the compressed air supply after testing the
valves.

5. Cleaning, maintenance and conversion

5.1 Cleaning the CDVI

The CDVI from Festo is a valve terminal especially for the
splash range in the food and packing industry. It features in
particular the following:

– Increased resistance to corrosion

– Resistance to acid and alkaline cleaning agents

– Compliance with relevant protection classes (see Appen-

dix A “Technical data”).

– Easy to clean.

Caution

Disinfectants may contain substances which can damage
the components of the CDVI in the long or short term
(e.g. sodium hypochlorite).

– Avoid using cleaning agents with a sodium hypochlorite

basis.
– Do not disinfect the CDVI with ultra-violet light.
– Note that the IP protection class refers to cold water

without cleaning agents. Cleaning agents can reduce

the surface tension.
In individual cases you should consult the manufacturer

of the cleaning agent/disinfectant regarding its compati­bility with the CDVI.

5-4

Festo P.BE-CDVI-E N en 1202e

5. Cleaning, maintenance and conversion

Clean the valve terminal as follows:

– Use aluminium-compatible cleaning agents (e.g. from

Henkel Ecolab, Diversy Lever or Kärcher)

Use the cleaning agent in the concentration, at the processing
temperature and in an environmentally friendly manner ac­cording to the specifications of the manufacturer (see data
sheet), but not at a processing temperature over +50°C.

•

After cleaning rinse the CDVI with plenty of clear water, so
that the cleaning agent cannot dry. Otherwise there will be
“increased concentration” which may damage the surface
of the CDVI.

5.2 General preventive action

Warning

Uncontrolled movements of the connected actuators and
uncontrolled movements of loose tubing can cause injury
to persons and/or damage to property.

•

Make sure that the higher-order controller has not sent

control signals to the solenoid coils.

•

Before carrying out conversion work on the CDVI, switch

off the following:

– The compressed air supply

– The power supply

The CDVI is supplied pre-assembled from the factory. If you
wish to supplement or replace individual components, please
note the following:

5-6

Festo P.BE-CDVI-E N en 1202e

5. Cleaning, maintenance and conversion

Note

Handle all the components of the CDVI with great care.
Note especially the following when mounting components:

•

Screws must be fitted accurately (otherwise threads will
be damaged).

•

Screws must be fastened only by hand. Screws must be
fitted so that the self-cutting threads can be used.

•

The specified torques must be observed.

•

Threaded connections must be mounted free of offset
and mechanical tension.

•

Avoid an offset between the components, otherwise the
protection class requirements may no longer be fulfilled
(see Appendix A, “T echnical data”).

•

Check the seals for damage before fitting (IP 65).

•

Make sure that the connecting surfaces are clean
(avoid leakage and contact errors).

•

In the case of components ordered at a later date,
observe also the fitting instructions supplied.

Caution

Components may be damaged if they are not handled
correctly.

•

Observe the handling specifications for electrostatically
sensitive devices.

•

Discharge yourself of static electricity before fitting or
removing the components in order to protect the
modules against static discharges.

•

Do not touch the contact surfaces of the plug connectors
on the sides of the components.

5.3 Dismantling/fitting the CDVI

Provided that the CDVI is easily accessible, it need not be
dismantled when the following components are replaced or
removed:

– Valves or blanking plates

– Expansion block

– End plates

Dismantling Proceed as follows:

1. If spacer bolts are used, remove these from the mounting
surface.

2. Disconnect the tubing at the working lines (2/4), at the
supply ports (1, 12/14), at the pressure compensation
port (L), and at the exhaust ports (3/5, 82/84) (see
chapter 3.2 “General connection technology”)

3. Disconnect the electrical connections:

5.4 Replacing valve terminal components

5.4.1 Valves and blanking plates

The valves and blanking plates of the CDVI can easily be
replaced or added.

All valve positions on the CDVI support triggering two sole­noid coils.

Dismantling Proceed as follows:

1. Clean and dry the CDVI so that the surfaces of the
in-line manifolds are clean.

2. Undo the mounting screws of the components
(see Fig. 5/1). Pay attention to the O-rings used as
locking agent.

3. Carefully pull the component off the in-line valve mani­fold.

Assembly Proceed as follows:

1. Check the valves to make sure that they are inserted as
far as possible into the valve cover.

2. Carefully plug the component onto the in-line valve mani­fold. Pay particular attention to the terminal lugs on
valves; these are not resistant to bending in alternate
directions.

5.5.1 Expansion block

T o facilitate mounting the expansion block, Festo recom­mends that you dismantle the CDVI from the mounting sur­face.
If the CDVI is easily accessible, the expansion block can also
be fitted without the need for you to dismantle the valve ter­minal. Combinations of Bi- and Mo-expansion blocks are per­missible. In the extension, at the most 8 solenoid coils can be
triggered.

– You can extend the CDVI by maximum

– 4 valve positions (when using exclusively Bi-expan-

sion blocks) or by

– 8 valve positions (when using exclusively Mo-expan-

sion blocks).

– When extending the CDVI, it is not possible to use

manifold blocks because screwing together multiple
manifold blocks has not been provided for in the design.

– In order to extend the CDVI, please use the components

listed in the following table.
