1.1

Overview of variants

Festo assists you in solving your automation task at the ma chine level with CPA valve terminals. The modular structure of the CPA valve terminal for the CP system enables you to adapt the CPA valve terminals optimally to your machine or system.

Due to their compact design, the CPA valve terminals can be fitted close to the actuators to be controlled. This enables short compressed air tubing to be used. System losses will therefore be minimized and the times required for pressuriz ing and exhausting the compressed air tubing will be redu ced. This is made possible by the use of very compact valves with sufficient flow, thereby helping to reduce costs.

CPA valve terminal with

CPX terminal

This CPA valve terminal is available with 2 to max. 22 single− solenoid valve locations or max. 11 double−solenoid valve locations. Maximum 22 valve coils can be controlled.

3.1

Preparing the compressed air

Caution

Non−filtered or incorrectly lubricated compressed air will reduce the service life of the valve terminal.

3.1.1 Operation with non−lubricated compressed air

Caution

Excessive 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 ester or na tive ester e.g. rape oil methylic ester), the residual oil content must not exceed 0.1 mg/m 3 (see ISO 8573−1 class 2).

If mineral oils are used (e.g. HLP oils as per

DIN 51524 parts 1 to 3) or corresponding oils on a poly alphaolefine basis (PAO), the residual oil content must not exceed 5 mg/m 3 (see ISO 8573−1 class 4).

In this way you will avoid malfunctioning of the valves.

A high residual oil content is not permitted, irrespective of the compressor oil, as otherwise the basic lubrication will be washed out in the course of time.

3.1.2 Operation with lubricated compressed air

If possible, operate your system with non−lubricated com pressed air. This will not pollute the environment. Pneumatic valves and actuators from Festo are designed so that, if used as designated, they will not require additional lubrication and will still achieve a long service life.

3−4

Festo P.BE−CPA−EN en 0306d

3. Installation

Lubricator setting

Check the setting

Festo P.BE−CPA−EN en 0306d

Caution

Operation with lubricated compressed air will lead to washing out" of the service life lubrication required for non−lubricated operation.

Note the following if lubricated compressed air has to be used.

The compressed air prepared with the compressor must correspond to the quality of non−lubricated compressed air. If possible, do not operate the complete system with lubricated compressed air. If possible, always fit the lubricator directly in front of the consuming actuator.

Caution

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

Use special oil OFSW−32 from Festo or the alternative oil listed in the Festo catalogue (corresponding 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).

Make sure that the lubricator is set correctly (see follow ing section)

In this way you will avoid malfunctioning of the valves.

With machine running (typical operating status) 0.2 to max. 1 drop/min. or 0.5 to 5 drops/1000 l air.

The lubricator setting can be checked as follows.

Proceed as follows:

· Check the service units as regards condensate and lubri cator setting twice a week.

1. Ascertain the actuator which is furthest from the lubrica tor.

3−5

3. Installation

2. Ascertain the valve terminal which controls this actuator.

3. Remove the silencer on connection 3/5, if fitted.

4. Hold a piece of white cardbord 10 cm in front of the ex haust port.

5. Let the system operate for some time.

The cardboard may only assume a slightly yellow col ouring. If oil drops out, this clearly indicates over−lu brication.

A further indication of over−lubrication is the colouring or status of the exhaust silencer. A clearly yellow colouring of the filter element or oil drops on the silencer indicate a too high lubricator setting.

General connection methods

Warning

Sudden unexpected movements of the connected actua tors and uncontrollable movements of loose tubing can cause injury to human beings and damage to property.

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

the compressed air supply

the operating and load voltage supplies

Observe the following:

The components of the valve terminals contain electrostati cally sensitive elements. The components may be damaged if the contact surfaces of the plug connectors are touched and if the regulations for handling electrostatically sensitive el ements are not observed.

Pilot control of the valve solenoid coils (auxiliary pilot air)

Caution

Operate the CPA valve terminal if possible with non−lu bricated auxiliary pilot air (connections 12/14). If lubri cated air must be used, observe the instructions in the section Preparing the compressed air".

In the case of CPA valve terminals with internally branched auxiliary pilot air, the above−mentioned in struction also applies to the supply air (connection 1).

In the case of CPA valve terminals with two pressure zones and internally branched auxiliary pilot air:

Due to the auxiliary pilot air branched internally in the right−hand end plate, the pressure in the right−hand pressure zone must be 3 − 8 bar.

Pilot control of the valve solenoid coils can be undertaken with internal or external auxiliary pilot air, depending on the right−hand end plate. You can ascertain the pilot control vari ant for which your CPA valve terminal is equipped by means of the type designation on the right−hand end plate (see table).

4.1

General instructions

4.1.1

Preparing for commissioning

· Switch off the power supply before connecting or discon necting plugs (this will prevent functional damage).

· Commission only a valve terminal which is fitted and wired completely.

· Make sure there is a sufficient supply of fresh air (cooling) for the following operating conditions:

when the maximum number of valves is fitted

when the maximum operating voltage is applied

when the solenoid coil is constantly stressed

· Note the following instructions on building up the com plete pressure supply.

4.1.2

Pressure build−up of the complete supply

Warning

If the build up of auxiliary pilot air is too slow or delayed, this may lead to sudden unexpected movements of the actuators under the following conditions:

when the compressed air is switched on via a safety start−up valve (slow build−up of pressure) and

when there are electric signals (e.g. after EMERGENCY

STOP).

This may cause damage to the machine or system and injury to human beings.

· Operate the valve terminal with external auxiliary pilot air (3 ... 8 bar). Branch the auxiliary pilot air in front of the safety start−up valve (see diagram).

4−4

Festo P.BE−CPA−EN en 0306d

4. Commissioning

Festo P.BE−CPA−EN en 0306d

The auxiliary pilot air must be applied with a pressure of 3 ...

8 bar immediately after being switched on. Otherwise it can not be guaranteed that the valve will switch directly (see dia gram).

If the pressure is less than 3 bar, there may be a delay before the valve switches, in spite of an electric signal. The slow build−up of pressure in the complete system then has no ef fect on the actuator. The actuator would react suddenly (e.g.

a cylinder would extend or retract suddenly, depending on the valve function).

Warning

Before actuating the manual override:

Unmonitored control of valve solenoid coils can cause actuators to perform sudden unexpected movements.

These can result in injury to human beings and damage to property.

· Disconnect the operating voltage supply to the valve solenoid coils at the relevant connections on the CPA valve terminal.

In this way you will avoid undesired movement of the valve solenoid coils.

Before applying the operating voltage:

Manual override actuations which are in the switched posi tion can cause actuators to perform sudden unexpected movements during commissioning. These could lead to injury to human beings and damage to property.

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

In this way you will avoid undefined switching states of the valves.

Proceed as follows:

Warning

Before checking the valve−actuator combination:

Make sure that nobody is in the danger zone.

Please note

A valve, which has been switched by an electric signal, cannot be reset by the manual override. The electric signal is dominant in this case.

· Reset the electric signal before actuating the manual override.

Caution

Manual override actuations which are in the switched posi tion can cause actuators to perform sudden unexpected movements during commissioning. These could lead to injury to human beings and damage to property. When the manual override is actuated, it is not possible to reset the valve to its basic position with an electric signal. The man ual override is dominant in this case.

· Make sure that double−solenoid valves (Ident. Code J) are reset to their basic positions. Actuate here the man ual override 12 of the relevant valve or apply current to pilot control solenoid 12.

· Reset the locking manual override actuations to the basic position. Valve plates with Ident. code H, K and N are each fitted with two valves. With manual override 14 you can control the valve on control side 14; with man ual override 12 you can control the valve on control side

12 (see switching symbols for valve plates in Appendix

B).

In this way, you can avoid undefined switching states when commissioning the machine/system.

Conversion of valve location for controlling one or two solenoid coils

The manifold sub−base determines the valves which can be fitted on a valve location (with one or two solenoid coils).

In order that a valve location can support one or two solenoid coils, you must replace the manifold on the relevant sub− base.

For conversion you will require:

Components manifold sub−base for controlling one solenoid coil or manifold sub−base for controlling two solenoid coils

Type

CPA..−EV1

Fitting Proceed as follows:

Please note

In the case of an extension of the CPA valve terminal with tie rod extension, make sure that this lies flush with the basis tie rod.

Use the tie rod extension only for two additional valve loca tions. Further tie rod extensions are not permitted. In this case use appropriately longer basis tie rods.

1. If you wish to add valve locations, fit the relevant manifold

(EV1 or EV2) to the sub−base. Then fit all valve locations and the end plate (see this chapter, Replacing end plates, sub−bases or manifold sub−bases").

2. Fit the relevant components onto the empty valve loca tions (see this chapter, Replacing valve plates, blanking plates or additional pressure supply plates").

3. Fit the CPA valve terminals onto the fastening surface (see chapter 2 Fitting, onto a wall" or onto a hat rail").
