1.1 The MPA valve terminal

Festo assists you in solving your automation tasks at machinelevel with MPA valve terminals. The modular structure of theMPA valve terminal enables you to use this valve terminal

optimally in your machine or system.

The valve terminal pneumatics provide the following:

� the common channels for supply and exhaust air

� the electric signals from all valve solenoid coils

Work connections 2 and 4 are provided for each valve loca�tion on the individual pneumatic modules. The valves aresupplied with compressed air via the common channels andconnections in the basic components. Both the exhaust airand pilot exhaust air from the valves are also exhausted viathese common channels. Further modules for pressure sup�ply are also available, e.g. in order to supply pressure zones.

The MPA valve terminal is fitted with current reduction. The

rated current of the valve solenoid coils is then reduced afterthe high−current phase (switching procedure). The currentreduction offers the following advantages:

� the MPA valve terminal has a lower energy consumption

� the power unit for the voltage supply to the MPA valveterminal can be designed more economically dependingon the individual case

� the valve solenoid coils have less leakage power and pro�duce less waste heat

3. Installation


3.1 Preparing the compressed air

CautionNon−filtered or incorrectly lubricated compressed air willreduce the service life of the valve terminal.

3.1.1 Operation with non−lubricated compressed air

CautionToo much residual oil in the compressed air will reduce theservice life of the valve terminal.

� If bio−oils are used (oils with synthetic ester or true esterbasis, e.g. rape oil methylester) the residual oil contentmust not exceed 0.1 mg/m3 (see ISO 8573−1 class 2).

� If mineral oils are used (e.g. HLP oils as per DIN 51524parts 1 to 3) or corresponding oils on a polyalphaolefinebasis (PAO), the residual oil content must not exceed 5mg/m3 (see ISO 8573−1 class 4).

You will thereby avoid functional damage to the valves.

Excessive residual oil cannot be permitted irrespective of thecompressor oil, as otherwise the basic lubrication will bewashed out during 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 prevent pollution of the environment.Festo pneumatic valves and cylinders have been designed sothat, if used as intended, they will not require additional lu�brication and will still achieve a long service life.

3. Installation


CautionOperation with lubricated compressed air will cause theservice life lubrication, which is necessary for non−lubri�cated operation, to be �washed out."

Please note the following instructions if lubricated com�pressed air must be used. The compressed air prepared with the compressor mustcorrespond in quality to non−lubricated compressed air. Ifpossible, do not operate the complete system with lubricatedcompressed air. If possible, always install the lubricators di�rectly in front of the consuming cylinder.

CautionIncorrect additional oil and too much residual oil content inthe compressed air will reduce the service life of the valveterminal.

� Use Festo special oil OFSW−32 or the other oils listed inthe Festo catalogue (as per DIN 51524−HLP32, basicviscosity 32cST at 40 °C).

� The additional lubrication must not exceed 25 mg/m3

(ISO 8573−1 class 5).

� Make sure that the lubricator setting is correct (see fol�lowing section)

You will thereby avoid functional damage to the valves.

Setting the lubricator: with the machine running (typical operating status) 0.2 tomax. 1 drop/min. or 0.5 to 5 drops/1000 l air.

Checking the setting: The procedure described below can be used for checking thesetting of the lubricator.

Proceed as follows:

· Check the service units in respect of condensate and lu�bricator setting twice a week.

1. Ascertain the cylinder which is furthest from the lubrica�tor.

3. Installation


2. Ascertain the valve terminal which controls this cylinder.

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

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

5. Let the system run for a short period.

� There must only be a slight yellow colouring on thecardboard. If oil drops out, this is an indication thattoo much oil has been used.

A further indication of excessive lubrication is the colouringor status of the exhaust silencer. A distinctly yellow colouringof the filter element or drops of oil on the silencer indicatethat the lubricator setting is too high.

3. Installation


3.2 General notes on connecting the tubing

WarningSudden unexpected movement of the connected actuatorsand uncontrolled movements of loose tubing can causeinjury to human beings or damage to property.


� the compressed air supply

� the operating and load voltage supplies.

Pay particular attention to the following:The components of the valve terminal contain electrostaticallysensitive elements. The components will be damaged if youtouch the contact surfaces of the plug connectors or if you donot observe the regulations for handling electrostaticallysensitive components.

3.2.1 Laying the tubing

If elbow screw 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 tubeconnection of the screw connector.

2. Pull the locking ring 1 over the tube connection ortighten the locking screw2.

3. Installation


3.3 Connecting the MPA valve terminal

In the case of sub−bases fitted with reserve plates, seal thework connections (2 or 4) with blanking plates or threadedblanking plugs to prevent dirt from entering.

In order to guarantee the optimum efficiency of the valve ter�minal, we recommend in the following cases that more than

one supply or exhaust line be used:

� when large volume cylinders are operated at high speeds

� when several valves are switched simultaneously to the

flow position

Connections on the following components are available forsupplying the valve terminal:

on the MPA valve terminal with CPX terminal:

� on the pneumatic interface

� on the supply unit, maximum between each sub−base(optional)

� on the supply unit next to the right−hand end plate

on the MPA valve terminal with MP connection:

� on the MP sub−base

� if necessary, on the supply unit next to the right−hand endplate

3. Installation


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

Depending on the pneumatic interface or MP sub−base fitted,pilot control of the valve solenoid coils can be carried out withinternal or external auxiliary pilot air. You can ascertain the

pilot control variant, for which your MPA valve terminal isequipped, by the following features (see table).

Table�3/1: Variants of the pneumatic interfaces or MP sub−base

Internal auxiliary pilot air If the supply pressure lies between 3 ... 8 bar, you can oper�

ate the pilot control of the valve solenoid coils with internallybranched auxiliary pilot air. In this case, the auxiliary pilot airin the pneumatic interface or in the MP sub−base is branched

from supply channel 1. �

3. Installation


Please note· Internal auxiliary pilot air is branched centrally from sup�ply connection 1 in the pneumatic interface or MP sub−base for all valve solenoid coils. This alsoapplies if the MPA valve terminal is operated with differ�ent pressure zones (see Figs. 3/4 and 3/5).

Auxiliary pilot air If the operating pressure lies below 3 bar or above 8 bar, pilot

control of the valve solenoid coils must be operated with ex�ternal auxiliary pilot air. In this case, the auxiliary pilot air is

supplied externally via pilot connection 12/14.

Please note· Use regulated external auxiliary pilot air.(3 ... 8 bar). Reliable faultless operation of the MPA valveterminal is then possible, even with fluctuating operat�ing pressure.

· The external auxiliary pilot air is supplied centrally viapilot connection 12/14 on the pneumatic interface or MPsub−base for all valve solenoid coils. This also applies ifthe MPA valve terminal is operated with different pres�sure zones (see Figs. 3/4 and 3/5).

· Set the external auxiliary pilot air to correspond to theoperating pressure with which these valves are operated(see diagrams).

Contents of this chapter This chapter describes the commissioning of the MPA valveterminal. The following in particular belong here:

� Checking the valve functions

� Operating the manual override

� Checking the valve−actuator combination

� Eliminating faults

� The assignment of the LEDs

Further information Commissioning the CPX terminal is described in the appropri�ate manual for the CPX field bus node.

4. Commissioning


4.1 General instructions

4.1.1 Before commissioning

· Switch off the power supply before connecting or discon�necting plugs (otherwise this could lead to functionaldamage).

· Commission only a valve terminal which has been fittedand 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 for building uppressure in the complete supply.

4.1.2 Pressure increase in the complete supply

WarningIf the build−up in pressure of the auxiliary pilot air is tooslow or delayed, this may cause the actuators to performsudden unexpected movements under the following condi�tions:

� If the compressed air is switched on with a safetystart−up valve (slow build up of pressure) and

� when there are electric signals (e.g. after EMERGENCYSTOP).

This can cause damage to the machine or system and eveninjury to human beings.

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

4. Commissioning


The auxiliary pilot air must reach a pressure of 3 ... 8 bar assoon as it is switched on, Otherwise, there is no guarantee

that the valve will switch directly (see diagram). If the pressure is less than 3 bar, there may be a delay beforethe valve is switched, in spite of an electric signal being pres�

ent. The slow increase in pressure of the complete supplydoes not then affect the actuator. The actuator would reactsuddenly (e.g. a cylinder would extend or retract, depending

on the valve function).

5.4.2 Replacing the electronic modules

The MPA valve terminal is fitted with one electronic moduleper sub−base. It provides for 4 valve locations the contactbetween the electrical linking and the solenoid coils. TheLEDs (function see chapter 4) and further electronic compo�nents are an integral part of the electronic module.

CautionThe electronic modules may be damaged if they are nothandled correctly.

· Switch off the power supply before removing the elec�tronic modules.

· Do not therefore touch any contact surfaces.

· Observe the regulations for handling electrostaticallysensitive components.

· Discharge yourself electrostatically before fitting or re�moving components in order to protect the componentsagainst discharges of static electricity.

Before removing the electronic module, you must first removeall valve plates or blanking plates on the relevant electronicmodule (see section �Removing valve plates or blankingplates�).


1. Loosen the screws with which the electronic module isfastened to the sub−base.

2. Pull the electronic module upwards out of the body of thesub−base.



Before fitting the electronic module

There are different designs of the electronic module depend�ing on the connection variant.


Please noteFeatures of the MPA valve terminal with CPX terminal de�pend on the type of electronic module fitted, e.g.:

� Electromagnetic compatibility (EMC)

� Switching off the valve power supply at all poles

You must observe the instructions in the manual for theCPX I/O modules if you wish to fit an electronic module ofa different type.

Recommendation:

Replace only with electronic modules of the same type.

The following types are available:

� Type VMPA1−FB−EMG−8: electronic module with 8 outputsand electrical isolation of the supply voltages.

� Type VMPA1−FB−EMS−8: electronic module with 8 outputswithout electrical isolation of the supply voltages.

5.5.2 Converting the MPA valve terminal to different pressure zones

The MPA valve terminal can be fitted with the followingnumber of pressure zones depending on the connecting vari�ant:

Electrical connection variant

CPX terminal MP connection

Pressure zones 1 ... 8 1 ... 2

Table�5/4: Number of pressure zones

The pressure zones are implemented by means of special

sheet seals which separate the following channels:

� only the supply channel (1)

� supply channel (1) and exhaust channels (3 and 5)

� only exhaust channels (3 and 5)



You can recognize by the marking on the seal, whether yourMPA valve terminal is fitted with pressure zones (see dia�

gram).

Conversion of the MPA valve terminal with MP con�nection

In order to convert the MPA valve terminal to two pressure

zones, you will require the following components:

� one sheet seal with pressure zone separation MPA−DP−...

� one supply unit if the MPA valve terminal is not yet fittedwith this.

Please noteThe MPA valve terminal with MP connection can be fittedwith max. one seal for pressure zone separation. The left−hand pressure zone is supplied via the MP sub−base; theright−hand pressure zone via a supply plate which is situ�ated next to the right−hand end plate.


1. Loosen the electrical and pneumatic connections and re�move the MPA valve terminal from the fastening surface(see section �Dismantling the MPA valve terminal" in thischapter).


3. Remove all valve plates and blanking plates and then allelectronic modules (see section �Dismantling valve platesor blanking plates")

4. Loosen the sub−base at the point where you wish to insertthe sheet seal for the pressure zone separation (see sec�tion �Dismantling sub−bases").

5.5.3 Adding valve locations

The MPA valve terminal with MP connection is available with4, 8, 12, 16, 20 or 24 valve locations. With this valve terminalvariant it is not intended that the number of valve locationsbe increased or reduced.

Adding valve locations

You can easily adapt the MPA valve terminal with CPX terminal

to the demands of your machine or system by adding valvelocations.

The smallest extension unit is a sub−base with 4 valve loca�tions.

For extension you will require:



Components Type

1 sub−base per 4 valve locations VMPA..−FB−AP−...

1 electronic module per sub−base VMPA..−FB−EM−...

4 valve plates or blanking plates per sub−base VMPA..−M1H−...

Table�5/6: Valve location extension


1. Loosen the MPA valve terminal from the fastening surface(see section �Dismantling the MPA valve terminal").

2. Dismantle the sub−base or the supply plate at the pointwhere you wish to extend the valve terminal (see section�Dismantling sub−bases").




1. Fit the new sub−base and, if necessary, a further supplyunit (see section �Fitting sub−bases").

2. Fit the valve plates or blanking plates onto the emptyvalve locations (see section �Fitting valve plates or blank�ing plates").
