1.1 The MPA−S valve terminal

Festo supports your automation tasks at machine level withthe MPA−S valve terminal. The modular structure of theMPA−S valve terminal enables you to match this valveterminal optimally to 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 (operating pressure and pilotpressure) via the common channels and connections in thebasic components. The exhaust air (from the valves and thepilot exhaust air) is also exhausted via these common chan�nels. Further components for pressure supply are also avail�able, e.g. in order to supply pressure zones.

The MPA−S valve terminal is equipped with current reduction.The rated current of the valve solenoid coils is then reducedafter the high−current phase (switching procedure). The cur�rent reduction offers the following advantages:

� the MPA−S valve terminal has a lower energy consumption

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

� the valve solenoid coils have less leakage power andproduce less waste heat.

The MPA−S valve terminal can be fitted with 2x3/2−way valves,5/2−way valves (single−solenoid and double−solenoid),5/3−way mid−position valves and proportional directionalcontrol valves.

All 5/2−way valves and 5/3−way mid−position valves can beused under all operating conditions:

� standard mode

� reversible mode

� low−pressure mode

� vacuum mode.

Identifying the valves The valves on the MPA−S valve terminal are marked byidentification codes. By means of this identification on thefront of the valve, you can ascertain the equipment fitted onyour MPA−S valve terminal.

Further information on the valves can be found in appendix B.

Proportional pressure regulator

The VPPM−6TA−... proportional pressure regulator has beendesigned to regulate a pressure proportional to a specifiedsetpoint value. An integrated pressure sensor records thepressure at the work connection and compares this with thesetpoint value. If the actual value differs from the setpointvalue, the pressure regulator is actuated further until thesetpoint value is reached. For constant pressure supply, which is necessary for accuratecontrol quality, the proportional pressure regulator has anadditional supply connection.

Configure the proportional pressure regulator via the PLC orthe Festo Handheld (CPX−MMI). How to fit the proportional pressure regulator is described inthe mounting instructions VPPM−6TA−... Information on configuring the proportional pressureregulator can be found in the appropriate electronics manual(see also table �Manuals on the CPX terminal" in the relevantsystem manual).



Identifying the propor�tional pressure regulator

The proportional pressure regulators on the MPA−S valveterminal are marked by identification codes. With thisidentification you can ascertain the type of proportionalpressure regulator.

Tab.�1/6: Identification code of the proportional pressure regulator

Pressure sensor plate

The pressure sensor plate serves for monitoring the followingdepending on the type:

� the operating pressure in channel 1 (type VMPA−FB−PS−1)

� an external processing pressure (type VMPA−FB−PS−P1)

� the pressure in the exhaust channels 3 and 5 (type VMPA−FB−PS−3/5).

By means of three LEDs the pressure sensor indicateswhether the pressure applied is less than, is equal to orexceeds the setpoint value. An additional LED shows commonfaults.



The MPA−S valve terminal can be equipped with up to4�pressure sensor plates.

The limit values for pressure monitoring are set via theparametrizing. You can parametrize the pressure sensor platevia the PLC or the Festo Handheld (CPX−MMI).

How to fit the pressure sensor plate is described in themounting instructions VMPA−FB−PS−... Information on parametrizing the pressure sensor can befound in the Electronics Manual CPX−I/O modules from Festo.

Pneumatic supply plate

You can supply the valves with operating pressure separatelyvia the pneumatic supply plate. This is for example necessaryin the case of valve terminals equipped with several pressurezones or when a large number of valves on the valve terminalare switched simultaneously to flow.

How to fit the pneumatic supply plate is described in chapter�5under �Replace sub−base, supply plate or MPA−S end plate".

Electric supply plate

You can supply the valves with load voltage separately via theelectric supply plate.

How to fit the electric supply plate is described in the mount�ing instructions VMPA−FB−SP−...



Pressure zone separation

The MPA−S valve terminal can be equipped with pressurezones.

The pressure zones are formed either by special sub−bases orby special isolating seals.

Separation of the pilot channels 12 and 14 is not intended,as on the MPA−S valve terminal the air supply for the pilotcontrol of the valves is supplied centrally via the pneumaticinterface or the multipin sub−base.

Pressure zone separation with sub−bases

Sub−base for the propor�tional pressure regulator

The sub−base (type VMPA−...) for the proportional pressureregulator always has a pressure zone separation and this isnot therefore marked additionally on the exterior of the sub−base. Pressure zone separation takes place:

� for channel 1 on the left−hand side of the sub−base.

� for channels 3 and 5 on the left−hand and on the right−hand side of the sub−base.

If the proportional pressure regulator is to regulate the op�erating pressure for the valves on the MPA−S valve terminal,the valves must be positioned to the right of the propor�tional pressure regulator.

Sub−bases for the valves On the sub−bases with integrated pressure zone separationthe separation is made in the centre of the sub−base, i.e.on�the

� MPA1: after the second valve position

� MPA2: after the first valve position.

The sub−bases are available in the following designs:

� only supply channel (1) separate

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



The sub−bases with integrated pressure zone separation aremarked with a notch. By means of the marking you can ascer�tain with which sub−base variant your valve terminal isequipped (see Tab.�1/7).

Sub−base design MPA1 MPA2

Sub−base with separate supplychannel 1

Type: VMPA−AP−4−1−S1 Type: VMPA−AP−2−2−S0

Tab.�1/7: Variants of the sub−bases with pressure zone separation



Pressure zone separation with isolating seals

The following channels can be separated with the isolatingseals (see also Tab.�1/8):

� only the supply channel (1)

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

� only the exhaust channels (3 and 5)

You can recognize whether your MPA−S valve terminal isequipped with pressure zones, and if so how many either bythe marking on the sub−base (see Tab.�1/7) or by the markingon the seal (see Tab.�1/8).

Pressure regulator P (identification PF, PA)

Mode of operation:

PressurizingThe pressure regulator P regulates the pressure in front ofthe valve in channel 1 (P). The same regulated work airpressure will then be present in channels 2 and 4.

ExhaustingIn the valve exhausting takes place from channel 2 tochannel 3 and from channel 4 to channel 5.

Pressure regulator P in channels 2 and 4 from channel 2 to channel 3 and from channel 4 to channel 5

Tab.�1/11: Pressure regulator P

The advantages of this pressure regulator are:

� The pressure regulator is not affected by venting, sincethe pressure is regulated before the valve.

� The pressure regulator can always be adjusted, since thepressure from the valve terminal is always present.

Application example:

� An equal working pressure is required at workingconnections 2 and 4.

� A lower working pressure (e.g. 3 bar) is required than theoperating pressure present at the valve terminal(e.g.�8�bar).



Pressure regulator A or B (identifier PH, PG, PC, PB)

Mode of operation:

PressurizingThe pressure regulator A or B regulates the relevantpressure of the work air (see 1 in Tab.�1/12) when thepressure medium has flowed through the valve. The exhaustair is passed through the intermediate plate and is switchedto the relevant exhaust channel in the valve (see�2 inTab.�1/12).

ExhaustingDuring exhausting the air is passed unregulated through thevalve and the pressure regulator (see 3 in Tab.�1/12).

Fig.�1/11 shows the following switching position of the pressure regulator B: The work air is passed from channel 1 through the intermedi�ate plate and the valve to the pressure regulator plate, whereit is regulated and then passed to connection 2 of the sub−base. The exhaust is passed unregulated via channel 4through the intermediate plate to the valve, where it ispassed to channel 5 and vented.

Restrictions:

� The exhaust flow is restricted in the regulating directionby the pressure regulator.

� The pressure of the work air in channel 2 can only be setand read on the pressure gauge when the valve is in theswitch position (flow from 1 } �2).



Application examples:

� If two different working pressures are required atconnections 2 and 4 instead of the operating pressure ofthe valve terminal:

� If it is not possible to use the reversible pressureregulator, e.g. when 2x3/2−way valves with ductedexhaust 82/84 are used.

Reversible pressureregulator A or B(identification PN, PM, PL, PK)

Operating method of the reversible pressure regulator:

PressurizingThe reversible pressure regulator splits up the supply air inchannel 1 and regulates the pressure in front of the valve inthe relevant channel (see 1 in Tab.�1/13), in the otherchannel (see 2 in Tab.�1/13) the unregulated pressure fromchannel 1 is present. The regulated air is then switched tothe relevant work channel. The valve is thus operated inreversible mode.

ExhaustingIn the valve the exhaust from the relevant work channel(see�3 in Tab.�1/13) is vented through channel 1 andpassed in the intermediate plate to the relevant exhaustchannel in the sub−base.

� The regulated pressure of the supply air is present inchannel 3. The pressure is regulated in front of the valve.

� The unregulated pressure of the supply air from channel 1is present in channel 5.

In the valve the regulated pressure is switched to channel 2.The unregulated exhaust is switched in the valve fromchannel 4 to channel 1 and then in the intermediate plate tochannel 3.

Advantages compared to the pressure regulator A or B:

� Faster cycle times

� 50 % higher exhaust flow rate, as air is not exhausted viathe pressure regulator. The load on the pressure regulatoris also reduced.

� No quick exhaust valves are required. The exhaust isducted completely via the valve terminal.

� The pressure regulator is always present at the pressureregulator, as the pressure is regulated before the valve,i.e. the regulator can always be adjusted. With pressureregulator A or B the valve must be switched for this.

Disadvantages compared to the pressure regulator A or B:

� Cannot be combined with 2x2/2−way valves with Ident.code D, I and 2x3/2−way valves with Ident. code N, K, H(non−reversible valves). These valves require operatingpressure in channel 1 for the pneumatic spring (seeswitching symbol in appendix B, Tab.�B/1 and Tab.�B/2).

Application examples:

� When two different pressures are required in ducts 2 and4 instead of the operating pressure of the valve terminal.

� When fast exhaust performance is required.

� When the pressure regulator must always be adjustable.

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 exceed5�mg/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. Installation


3.1.2 Operation with lubricated compressed air

Operate your system with non−lubricated compressed air ifpossible. This will prevent pollution of the environment. Festopneumatic valves and actuators have been designed so that,if used as intended, they will not require additional lubrica�tion and will still achieve a long service life.

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

Note the following instructions if lubricated compressed airmust 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 lubricatorsdirectly in front of the consuming actuator.

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 32 CST 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 following section).

You will thereby avoid functional damage to the valves.

3. Installation


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 andlubricator setting twice a week.

1. Ascertain the cylinder which is furthest from thelubricator.

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 theexhaust port.

5. Let the system run for a short period.

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

Another indication of over−lubrication is the colouring or thecondition of the exhaust air silencer. A distinctly yellowcolouring of the filter element or drops of oil on the silencerindicate that the lubricator setting is too high.

3.2 General instructions on installation



� the compressed air supply

� the operating and load voltage supplies.

NoteObserve the following if the UL requirements are to becomplied with in your application:

� Rules for observing the UL certification can be found inthe separate UL−specific documentation. The relevanttechnical specifications listed there also apply here.

� The technical specifications in this documentation mayshow different values.

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. Installation


NoteWhen large−volume actuators are exhausted or if theexhaust performance is too low, back pressures can occurin the exhaust channels of the valve terminal. The backpressures can lead to other valves being pressurized,especially non−switched 3/2−way valves which are closedin the normal position.

Avoiding back pressures

� Optimize the exhaust peformance of the valve terminal,e.g by using additional pneumatic supply plates.

� If necessary, separate the exhaust channels with theisolating seals with Ident. code R (channels 3 and 5blocked, see Tab.�1/8).

3. Installation


3.3 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 tubing connection ortighten the locking screw 2.

3. For reasons of clarity, group the tubing together with: � tube straps or� multiple hose holders.

Fig.�3/1: Fitting the tubing

Disconnecting Proceed as follows:

WarningIf the pneumatic tubing is under pressure when connec�tions are loosened, it may perform sudden unexpectedmovements, thereby causing injury to human beings. Carry out the following steps before disconnecting thepneumatic tubing on the MPA−S valve terminal:

· Switch off the compressed air supply.

· Make sure that all pneumatic tubing is pressureless.

· Exhaust all actuators controlled by valves which areblocked in the rest or mid−positions.

3. Installation


1. Mark all pneumatic tubing.

2. Press down the locking ring of the screw connector 1e.g. with a screwdriver or the loosening tool QSO fromFesto or loosen the locking screw 2 of the screwconnector.

3. Remove the tubing from the screw connector.

4. Seal non−required screw connectors with blankingplugs�3.

3. Installation


3.4 Connecting the MPA−S valve terminal

On sub−bases fitted with cover plates seal the work connec�tions (2 or 4) with blanking plates or threaded blanking plugs.This measure will protect the connections from dirt.

For the optimum performance of the valve terminal we recom�mend that the valves be supplied via more than one supplyand exhaust line when:

� more than 6 valves of size MPA1 or

� more than 3 valves of size MPA2

are switched simultaneously to flow.

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

on the MPA−S valve terminal with CPX terminal:

� on the pneumatic interface

� on the optional pneumatic supply plate, maximumbetween each sub−base

on the MPA−S valve terminal with multipin connection:

� on the multipin sub−base

� on the optional pneumatic supply plate, maximumbetween each sub−base.

3. Installation


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

Depending on the variant of the pneumatic interface or multi�pin sub−base, pilot control of the valve solenoid coils is car�ried out with internal or external pilot air. You can ascertainthe pilot control variant for which your MPA−S valve terminalis equipped, by the following features (see table).

Pilot control variants Pilot control connection 12/14 on the pneumaticinterface or multipin sub−base

Operation with external pilot air marked and open

Operation with internal pilot air not marked and closed

Tab.�3/1: Recogniton features of the pilot control variants

Internal pilot air supply If the operating pressure lies between 3 � 8 bar, you canoperate the pilot control of the valve solenoid coils with in�ternally branched pilot air. The auxiliary pilot air is branchedhere in the pneumatic interface or from supply channel 1 inthe multipin sub−base.

Note· Internal pilot air is branched centrally for all valve coilsfrom supply connection 1 in the pneumatic interface ormultipin sub−base. This also applies when the MPA−Svalve terminal is operated with several pressure zones(see Fig.�3/3).

External pilot air supply If the operating pressure lies below 3 bar or above 8 bar,pilot control of the valve solenoid coils must be operatedwith external pilot air. The pilot air is supplied via pilotconnection 12/14.

3. Installation


Note· Use closed−loop regulated external pilot air (3 � 8 bar).Reliable faultless operation of the MPA−S valve terminalis then possible, e.g. even with fluctuating operatingpressure.

· The external pilot air for all valve solenoid coils issupplied centrally via pilot connection 12/14 dependingon the electric connection variant on the pneumaticinterface or on the multipin sub−base. This is the caseeven if the MPA−S valve terminal is operated withdifferent pressure zones.

· Set the external pilot air to correspond to theoperating pressure at which these valves are operated (see diagrams in appendix A Fig.�A/1 and Fig.�A/2).

3.4.2 MPA−S valve terminal with pressure zone separation

The pressure zones are formed either by special sub−bases orby special isolating seals.

You can ascertain whether your MPA−S valve terminal isequipped with pressure zones, and if so how many by themarking on the sub−base (see chapter 1, Tab.�1/7) or by themarking on the seal (see chapter 1, Tab.�1/8).

The sub−base (type VMPA−...) for the proportional pressureregulator always has a pressure zone separation and this isnot therefore marked additionally on the exterior of the sub−base. The pressure zone separation of channels 1, 3 and 5takes place on the left−hand side of the sub−base.

3. Installation


Note· Operate the valves with Ident. code I (2x2/2−way valve)in a separate pressure zone with separate exhaustchannnel 5 if the MPA−S valve terminal is also fitted withother valves.

Note the following in the case of the MPA−S valve terminalswhich are operated with internal pilot air and which haveseveral pressure zones:

· The pilot air supply is branched centrally for all valvecoils from supply connection 1 in the pneumatic inter�face or from the multipin sub−base (see Fig.�3/3).

· The pressure zone, which is supplied via the supplyconnection �1 of the pneumatic interface or the multipinsub−base, must be operated at a pressure between3��8 bar.

If the proportional pressure regulator is to regulate the oper�ating pressure for the valves on the MPA−S valve terminal, thevalves must be positioned to the right of the proportionalpressure regulator.

The following diagram shows as an example of an MPA−Svalve terminal with blocked channels 1, 3 and 5 the assign�ment of the supply and exhaust connections to the valves.

A pressure zone seal and a pneumatic supply plate isrequired for each pressure zone (see figure).

The connections 1 or 3/5 are:

� for the pressure zone on the outside left of the pneumaticinterface or multipin sub−base.

� for all other pressure zones on the pneumatic supplyplate which lies within the relevant pressure zones. The position of the supply plate in the pressure zone (left,centre or right) is optional, but two supply plates (e.g. ofneighbouring pressure zones) must not lie next to eachother.

3. Installation


By fitting an additional pneumatic supply plaate within apressure zone you can provide additional supply air or extractexhaust air.

3.4.3 Operation of the MPA−S valve terminal with reversible pressureregulators

NoteOperation of the MPA−S valve terminal with reversiblepressure regulators (Ident. code PN, PM, PL, PK):

· Reversible pressure regulators must not be used onreversibly operated valve terminals.

· No 2x2/2−way valves with Ident. code D, I or 2x3/2−wayvalves with Ident. code N, K, H (non−reversible valves)may be operated with these pressure regulators.

3.4.4 Setting the pressure regulator

3.4.5 Vacuum / low pressure operation

NoteThe 2x2/2−way valves with Ident. code D, I and the2x3/2−way valves with Ident. code N, K, H are not suitablefor vacuum or low pressure operation if they are suppliedvia connection 1.

· Operate these valves in a separate pressure zone.

· The operating pressure for this pressure zone must beset in accordance with the diagram in Fig.�A/1.

If valves are used for switching vacuum, filters must beused in the suction line in order to avoid functionaldamage due to dirt.

The following conditions must be fulfilled before you canoperate your MPA−S valve terminal at supply connection 1with vacuum or low pressure between −0.9 � 3 bar:

� The pilot control of the valve solenoid coils is operatedwith external closed−loop regulated pilot air.

� The valve terminal is fitted with the following valve platesand, in some cases has further pressure zones.

· Use only power packs which guarantee reliableelectrical isolation of the operating voltage as perIEC/DIN EN�60204−1.

By the use of PELV power units, protection against electricshock (protection against direct and indirect contact) isguaranteed in accordance with IEC/DIN EN 60204−1(electrical equipment of machines, general requirements).

NoteCheck within the framework of your EMERGENCY STOPcircuit, to ascertain the measures necessary for puttingyour machine/system into a safe state in the event of anEMERGENCY STOP (e.g. switching off the operating voltagefor the valves and output modules, switching off thecompressed air).

MPA−S valve terminal with CPX terminal: Instructions on connecting the operating voltage can befound in the system manual.

Detailed instructions on connecting CPX modules (bus node,I/O modules etc.) can be found in the relevant manuals forthe CPX modules (see system manual for your CPX terminal,table �Manuals on the CPX terminal").

MPA−S valve terminal with multipin connection: Instructions on connecting the electric elements of the MPA−Svalve terminal with multipin connection can be found in theleaflet supplied with the product.

3. Installation


Additional load voltage supply of the valves via anelectric supply plate

The electric supply plate type VMPA−FB−SP−...−V−... serves forsupplying the valves additionally with load voltage when, forexample, the valve terminal is to be operated with differentvoltage zones or when the necessary load voltage canot beprovided by the CPX terminal alone.

NoteDamage to components and functional damage

Please note:

� that with MPA−S valve terminals with more than8�sub−bases an electric supply plate is required forsupplying the load voltage.

� that only the electronic modules with electrical isolationtype VMPA�...−FB−EMG−... are permitted to the right of theelectric supply plate (see also section 5.3.5). If yourMPA−S valve terminal is to be equipped only withelectronic modules without electrical isolation(type�VMPA�...−FB−EMS−...), the pneumatic componentsmust be supplied exclusively via the manifold block withthe system supply (type CPX−GE−EV−S) of the CPXterminal.

� that the electric supply plate must not be installeddirectly to the left of a pneumatic supply plate(type�VMPA1−FB−SP−...).

� that you do not touch the electrostatically sensitivecontact surfaces of the plug connectors on the side ofthe electric supply plate.

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

� Instructions on building up pressure in the completesupply

� Operating the manual overrides

� Checking the valves and the valve−actuator combination

� The assignment of LEDs and manual overrides to the valvesolenoid coils

� Function impairments

� Operating states of the pneumatic system

Further information The commissioning of the CPX terminal is described in therelevant manual for the CPX bus node (see system manual foryour CPX terminal, table �Manuals on the CPX terminal").

4. Commissioning


4.1 General instructions

4.1.1 Before commissioning

· Switch off the power supply before connecting ordisconnecting plugs (otherwise this could lead tofunctional damage).

· 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 valve coils are constantly under stress.

· Please observe the following instructions on 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 followingconditions:

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

� if there are electric signals (e.g. after EMERGENCY STOP).

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

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

4. Commissioning


The pilot air must reach a pressure of 3 � 8 bar as soon as itis switched on, Otherwise, there is no guarantee that thevalve 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 suddenly,depending on the valve function).

Tab.�4/3: Commissioning variants

Commissioning the pneumatic components by means of themanual override is described below.

The commissioning of the CPX terminal is described in therelevant manual for the CPX bus node (see system manual foryour CPX terminal, table �Manuals on the CPX terminal").

4. Commissioning


WarningBefore actuating the manual override:

Uncontrolled actuation of the valve coils can cause theactuators to perform sudden unexpected movementswhich may cause injury to human beings and damage toproperty.

· Disconnect the power supply for the valve solenoid coilsat the relevant connections on the MPA−S valve terminal.

You will thereby avoid undesired actuation of the valvecoils.

Before switching on the power supply:

During commissioning, manual override functions whichare in the switched state can cause actuators to performsudden unexpected movements. These movements cancause injury to human beings and damage to property.

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

You will thereby avoid undefined switching states of thevalves.

Proceed as follows:

WarningBefore testing the valve−actuator combination:

� make sure that nobody is in the danger zone.

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

· Reset the electric signal before actuating the manualoverride.

4. Commissioning


1. Switch on the compressed air supply.

2. Check the functioning and operation of each individualvalve−actuator combination by actuating the manualoverride as shown in the following diagrams.

NoteIncorrect actuation of the non−locking manual override canlead to malfunctioning or damage to the manual override.

· Use a screwdriver (blade width max. 3 mm) for actuatingthe manual override.

· Actuate the manual override with only max. 25 N.

3. With the locking function of the manual override: After testing the valves, make sure that all manualoverride actuations are in their basic positions again.

CautionValves with manual overrides in switch position can moveactuators unintentionally during commissioning. This cancause injury to people and damage to property.

· Before commissioning, reset all manual overrides totheir basic positions again.

If the manual override is in the actuated state, it is notpossible to reset the valve to its basic position with anelectric signal. The manual override is dominant in thiscase.

4. Commissioning


4.6 Commissioning instructions for the proportional pressure regulator

Note� Place the proportional pressure regulator as near aspossible to the consuming device. This will lead to bettercontrol accuracy and shorter response times.

� Make sure there is sufficient space for the connectingelements. In this way you will prevent the connectingcable from being bent.

� Long signal cables reduce the immunity to interference.Make sure that the signal cables are not longer than10�m.

� Make sure that the proportional pressure regulator isnot subjected to high−frequency irradiation (e.g. by radiosets, mobile telephones or other devices which causeinterference). In this way you will avoid increased toler�ances in the output pressure (compare specifications onEMC in appendix A).

� The proportional pressure regulator interprets nominalvalues which are smaller than 1 % full scale as zero pointswitching off, i.e. the valve is force−ventilated and there�fore assumes a defined position.

� Pressurise the proportional pressure regulator with aninput pressure at least 1 bar higher than the maximumrequired output pressure. A proportional output pres�sure P2 sets itself as the nominal value. Tab.�4/9 showsthe output pressure which is assigned to the end ranges(1 % FS or 100 % FS) of the nominal value.

� When switching off the proportional pressure regulator,make sure that first the supply pressure, then the supplyvoltage is switched off.

5.3.5 Replacing electronic modules

How to fit the proportional pressure regulator is described inthe mounting instructions VMPA−6TA−...

The MPA−S valve terminal is fitted with one electronic moduleper sub−base. It provides the following number of contactsbetween the electrical linking and the solenoid coils, depend�ing on the size of the sub−bases.

� for size MPA1 contacts for 4 valve locations

� for size MPA2 contacts for 2 valve locations.

The LEDs (function see chapter 4) and further electroniccomponents are integral parts of the electronic module.

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

· Switch off the power supply before removing theelectronic modules.

· Do not touch any contact surfaces.

· Observe the handling specifications for electrostaticallysensitive components.

· Discharge yourself before installing or removingsub−assemblies to protect the sub−assemblies fromstatic discharges.

CautionReplace an electronic module only by an electronic moduleof the same type.



Before fitting the electronic module

There are different designs of electronic modules dependingon the connection variant.

Electronic modules for the MPA−S valve terminal withCPX�terminal

CautionDamage to components and functional damage

It is not permitted to supply voltage to MPA pneumaticmodules with electronic modules without electrical isola�tion via a manifold sub−base type CPX−GE−EV−V... (valvesupply) or CPX−GE−EV−S−7/8−5POL (5−pin system supply).

· If your MPA pneumatics are fitted with electronicmodules of type VMPA1−FB−EMS−... orVMPA2−FB−EMS−..., you must supply the MPA pneumatcsexclusuvely via a 4−pin system supply module typeCPX−GE−EV−S or CPX−GE−EV−S−7/8−4POL.

Note the overview in Tab.�5/2.

Note that MPA electronic modules may only be supplied withpower via the following supply modules:

MPA electronic module Permitted supply modules

... without electrical isolation� VMPA1−FB−EMS−...� VMPA2−FB−EMS−...

� System supply (M18, 4−pin): type CPX−GE−EV−S� System supply (7/8", 4−pin): type CPX−GE−EV−S−7/8−4POL

1) If a 4−pin system supply is used, there will be no electrical isolation.

Tab.�5/2: Permitted supply modules for MPA electronic modules



In the case of MPA electronic modules with electrical isolationtype VMPA1−FB−EMG−... or VMPA2−FB−EMG−..., VEL/SEN andVVAL are completely electrically isolated. In conjunction withthe following voltage supply modules, it is therefore possibleto switch off the valve supply voltage at all poles:

� manifold sub−base with valve supply (M18 or 7/8"): type�CPX−GE−EV−V...

� system supply (7/8", 5−pin): type�CPX−GE−EV−S−7/8−5POL

� electric supply plate MPA: type�VMPA−FB−SP−...−V−...

NoteThe electrical function of an MPA pneumatic module isdetermined by the electronic module used, 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 electronic modules type VMPA�...−FB−... support thecontrol of two valve solenoid coils per valve location.



The following electronic modules are available:

5.4.3 Adding valve locations

You can easily adapt the MPA−S valve terminal to the require�ments of your machine or system by adding valve locations.The smallest extension unit is a sub−base with 4 valve loca�tions (MPA1) or 2 valve locations (MPA2).


The valve terminals can be configured with as many sub−bases as there are addresses available (see table). With thesevalve terminals, the maximum number of solenoid coils whichcan be actuated by the multipin connection is limited to24�addresses.

If control is carried out with size MPA 1 or MPA 2 and valveswith the same number of solenoid coils, this will result in thefollowing maximum number of sub−bases:

MPA−S valve terminal Valve locations persub−base (n1)

Valve coils per valve location (n2)
