1.1 The MPA−F valve terminal

Festo supports your machine table automation tasks with theMPA−F valve terminal. The modular design of this valve ter�minal allows you to optimally customize the valve terminal tosuit your machine or plant.

The pneumatic valve terminal provides the following connec�tions:

� Common channels for supply and exhaust air

� Electric signals for all solenoid coils

Working lines (2) and (4) are provided for each valve positionon the individual pneumatic modules. The valves are suppliedwith compressed air (operating pressure and pilot pressure)via the common channels and connections in the basic com�ponents. The exhaust air (from the valves and the pilot ex�haust air) is also exhausted via these common channels.Further modules for pressure supply are also available, e.g. in order to supply pressure zones.

The valve terminal is fitted with current reduction. The ratedcurrent of the solenoid coils is reduced after the high−currentphase (switching operation). The current reduction offers thefollowing advantages:

� The valve terminal has a lower energy consumption

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

� The solenoid coils have less leakage power and produceless waste heat

� The pressure in exhaust ducts (3) and (5)(type VMPAF−FB−PS−3/5).

The pressures sensor uses three LEDs to indicate whether theexisting pressure exceeds, complies with, or lies below thesetpoint value. An additional LED indicates common errors.

The MPA−F valve terminal can be equipped with up to 4 pres�sure sensor plates.

The limit values for pressure monitoring are set via parame�trisation. The pressure sensor plate can be parametrised viathe PLC or the Festo Handheld (CPX−MMI).

The assembly of the pressure sensor plate is described in theVMPA−FB−PS−... assembly instructions.Information on parametrising the pressure sensor is providedin the MPA−... electronics description from Festo.

Pressure sensor on pneumatic interface

The optional pressure sensor on the pneumatic interface isused to monitor the operating pressure in channel (1)

The display shows the numerical value of the monitored pres�sure. The corresponding units of the pressure value are indi�cated by the �psi" or �bar" LEDs.



The pressures sensor uses three further LEDs to indicatewhether the existing pressure exceeds, complies with, or liesbelow the setpoint value. An additional LED indicates com�mon errors.

The limit values for pressure monitoring are set via parame�trisation. The pressure sensor can be parametrised via thePLC or the Festo Handheld (CPX−MMI).

Pneumatic supply plate

You can use the pneumatic air supply plate to separately sup�ply the valves with operating pressure and remove the ex�haust air in a ducted or unducted manner. Separate operatingpressure is (e.g.) required for valve terminals equipped withmultiple pressure zones or if many valves on the valve ter�minal are opened at the same time.

Mounting of the pneumatic air supply plate is described inchapter 5 under �Replacing the manifold block, air supplyplate or MPA−F end plate".

Exhaust plates

The MPA−F valve terminal can be equipped with the followingcomponents for removing the exhaust air:

� With a flat plate silencer, when the exhaust air should beremoved unducted

� With an exhaust plate with connection (3/5), when theexhaust air of channels (3) and (5) should be removedtogether

� With an exhaust plate with connections (3) and (5), whenthe exhaust air of channels (3) and (5) should be removedseparately.



Use the exhaust plate with separate exhaust ports (3) and (5)when you:

� Want to reversibly operate the MPA−F valve terminal.

� When you want higher exhaust performance per exhaustplate.

Electrical supply plate

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

The assembly of the electrical supply plate is described in theVMPAF−FB−SP−...−V−... assembly instructions.

Pressure zone separation

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

The pressure zones are formed either by special manifoldblocks or by special separating seals.

Pressure zone separation of the pilot air ducts 12/14 and82/84 is not intended, since the pilot air supply of the MPA−Fvalve terminal is fed centrally via the right end plate and thepilot air is also vented here.

Pressure zone separation with manifold blocks

Manifold blocks to thevalves

In the manifold block with integrated pressure zone separ�ation, the separation occurs in the middle of the manifoldblock, i.e. with

� MPA1: after the second valve position

� MPA2: after the first valve position.

With this manifold block the supply duct (1) is separate.



The manifold block with integrated pressure zone separationis identified by a notch (see Tab.�1/4).

MPA1 MPA2

Type: VMPAF−AP−4−1−T1 Type: VMPAF−AP−2−2−T0

Tab.�1/4: Manifold blocks with pressure zone separation

Pressure zone separation with separator plates

The following channels can be separated with the separatingseals:

� only the supply duct (1)

� the supply duct (1) and exhaust ducts (3 and 5)

� only the exhaust ducts (3 and 5)

You can discover if your MPA−F valve terminal is equippedwith pressure zones or how many pressure zones it isequipped with, from the identification notch in the manifoldblock (see Tab.�1/4) or from the seal markings (see Fig.�1/9).

Tab.�1/6: Identification of the pressure regulator plates in the type code

The circuit symbol of the pressure regulating valve is pro�vided in appendix B, Tab.�B/5.



P pressure regulatingvalve (Ident. code PF, PA)

Mode of operation:

Supply process:The P−pressure regulating valve regulates the pressure infront of the valve in channel (1) (P). This provides the same

regulated working air pressure in channels (2) and (4).

Exhaust process:The exhaust flow is from channel (2) to channel (3) and fromchannel (4) to channel (5).

The advantages of this pressure regulating valve are:

� The pressure regulating valve is not affected by venting,since the pressure is regulated upstream of the valve.

� The pressure regulating valve can always be adjusted, sincethe pressure from the valve terminal is always present.

Application example:

� An equal working pressure is required at working lines (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).

B or A pressure regulatingvalve (Ident. code PH, PC,PG, PB)

Mode of operation of the B pressure regulating valve:

Supply process:The B pressure regulating valve regulates the working pres�sure in channel (2) after the pressure medium flows throughthe valve. The exhaust air is channelled through the inter�mediate plate and switched from channel (4) to channel (5)in the valve.

Exhaust process:During venting, the exhaust flow in the valve is unregulatedfrom channel (2) to channel (3) via the pressure regulatingvalve.



Fig.�1/10 shows the following switching position of the Bpressure regulating valve:The working air is passed from channel (1) through the inter�mediate plate and the valve to pressure regulating valve B,where it is regulated and then passed to connection (2) of themanifold block. The unregulated exhaust air is then fed viachannel (4) through the intermediate plate and then to chan�nel (5) and vented.

Mode of operation of the A pressure regulating valve:

Supply process:The A pressure regulating valve regulates the working pres�sure in channel (4) after the pressure medium flows throughthe valve. The exhaust air is channelled through the inter�mediate plate and switched from channel (2) to channel (3) inthe valve.

Exhaust process:During venting, the exhaust flow in the valve is unregulatedfrom channel (4) to channel (5) via the pressure regulatingvalve.

Restrictions:

� The exhaust flow in the regulating direction is limited bythe pressure regulating valve.

� The pressure in channel (2) can only be set and read at the pressure gauge when the is activated (flow from 1 } 2).

Application examples:

� If a different working pressure to the operating pressureof the valve terminals is required at connections (2) or (4).

� If the reversible pressure regulating valve cannot be used.



Reversible B or A pressure regulatingvalve (identifiers PN, PL, PM, PK)

Mode of operation of the reversible B pressure regulatingvalve:

Supply process:The reversible B pressure regulating valve splits the supplyin channel (1) and regulates the pressure upstream of thevalve in channel (3) (channel (5) receives the unregulatedpressure from channel (1)). Thereafter the regulated air isswitched to working channel (2). The valve is thus operatedin reversible mode.

Exhaust process:Venting occurs in the valve from working channel (2) tochannel (1) and in the intermediate plate to the manifoldblock exhaust duct (3).

Fig.�1/11 shows the following switching position of the revers�ible B pressure regulating valve:The working air in channel (1) is split:

� The regulated working pressure is present at channel (3).The pressure is regulated before the valve.

� The unregulated working pressure from channel (1) ispresent at channel (5).

The regulated pressure is switched to channel (2) inside thevalve. The unregulated exhaust air is switched inside thevalve from channel (4) to channel (1) and then in the inter�mediate plate to channel (3).

Fig.�1/11: Reversible B pressure regulating valve

Mode of operation of the reversible A pressure regulatingvalve:

Supply process:The reversible B pressure regulating valve splits the supply inchannel (1) and regulates the pressure upstream of the valvein channel (5) (channel (3) receives the unregulated pressurefrom channel (1)). Thereafter the regulated air is switched toworking channel (4). The valve is thus operated in reversiblemode.

Exhaust process:Venting occurs in the valve from working channel (4) to chan�nel (1) and in the intermediate plate to the manifold blockexhaust duct (5).



Advantages of A or B pressure regulating valves:

� Faster cycle times

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

� No quick exhaust valves are required.

� Operating pressure is always present at the pressureregulating valve, as the pressure is regulated upstream ofthe valve, i.e. the regulator can always be adjusted. WithA or B pressure regulating valves the valve must switchfor this.

Disadvantages of A or B pressure regulating valves:

� Cannot be combined with 2x2/2−way valves with Ident.codes D, I and 2x3/2−way valves with Ident. codes H, K, N(non−reversible valves). These valves require working pres�sure in channel (1) for the pneumatic spring (see circuit sym�bol in appendix B, Tab.�B/4 and Tab.�B/3).

Application examples:

� When the working pressure in channel (2) or (4) shouldnot be the same as the operating pressure of the valveterminal.

� When fast exhaust performance is required.

� When the pressure regulating valve must always be adjustable.

� Electrostatic sensitive devices.Do not therefore touch any contact surfaces.

2. Assembly


2.2 Mounting variants

You can fit the MPA−F valve terminal in one of two ways:

Mounting method Description

H−rail mounting The MPA−F valve terminal is suitable formounting onto an H−rail (DIN mounting railas per EN 60715). There is a guide grooveon the back for hanging the valve terminalonto the hat rail.

Wall mounting The multiple connector plate or the pneu�matic interface and the end plates containholes for wall mounting. Note:MPA−F valve terminals having a pneumaticlength of over 300 mm may require addi�tional fastening brackets on the manifoldblocks (see following note and the vibra�tion and shock specifications in appendixA, Tab.�A/3).

Tab.�2/1: Mounting methods for the MPA−F valve terminal

NoteMount the MPA−F valve terminal so that there is sufficientspace for heat dissipation and ensure that the maximumlimits for temperatures are observed (see appendix A,�Technical data").

2. Assembly


2.2.1 Mounting / dismounting on an H−rail

CautionH−rails with mounted valve terminals can break if they aresubjected to vibration exceeding severity level 1:

� 0.15 mm path at 15 ... 85 Hz

� 2 g acceleration at 58 ... 150 Hz

This can damage the valve terminal, your machine or yoursystem.

· In this case use wall mounting.

· Note the permitted values for vibration and shock inappendix A �Technical data".

Caution� Hat−rail mounting without an H−rail clamping unit is notpermitted.

· Secure the MPA−F valve terminal using the H−rail clamp�ing:� against sliding down with the retaining screw intendedfor this purpose (see Tab.�2/2 and Fig.�2/1)

� against unintentional releasing/opening.

In order to mount the valve terminal onto an H−rail you willrequire the following mounting kits:

� for MPA−F valve terminals with multi−pin plug connection: CPA−BG−NRH. This kit contains 2 M4x10 screws and 2 clamping elements.

� for MPA−F valve terminals with CPX terminal: VMPAF−FB−BG−NRH. This set consists of 3 clamping com�ponents, two M4x12 screws and one M4x10 screw.

3.1 Compressed air preparation

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 the basis of poly�alphaolefine (PAO), the residual oil content must notexceed max. 5 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.

3.1.2 Operation with lubricated compressed air

Operate your equipment with unlubricated 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.

3. Installation


CautionOperation with lubricated compressed air will cause thelife−time lubrication, which is necessary for non−lubricatedoperation, 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 all of your equipment with lubricatedcompressed air. If possible, always install the lubricators di�rectly 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 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 lubricator setting twice a week.

1. Ascertain the actuator 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 be only a slight yellow colouring on thecardboard. If oil drops out, this is an indication thattoo much oil has been used.

Another indicator of over−lubrication is the coloration or thecondition of the exhaust air silencer. A distinctly yellow col�ouring of the filter element or drops of oil on the silencer indi�cate that the lubricator setting is too high.

3. Installation


3.2 General notes on connecting the tubing



� 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.

NoteWhen exhausting large volume actuators or if the exhaustperformance is too small, back pressures can build up inthe valve terminal exhaust ducts. The back pressures canlead to pneumatic actuation of other valves, especiallywith unswitched 3/2−way valves that are normally closed.To avoid back pressures:

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

� If necessary, separated the exhaust ducts using the sep�arating seal with Ident. code: R (ducts (3) and (5) closed,see chapter 3, Fig.�1/9).

3. Installation


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 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. Carryout the following steps before disconnecting the pneu�matic tubing on the MPA−F 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 screw con�nector.

3. Remove the tubing from the screw connector.

4. Seal non−required screw connectors with blanking plugs 3.

3. Installation


3.3 Connecting the MPA−F valve terminal

In the case of manifold blocks fitted with cover plates, sealthe work connections (2 or 4) with blanking plates orthreaded blanking plugs to prevent dirt from entering.

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

Port (1):

� On the electrical interface(Pneumatic interface, CPI−inter�face, multiple connector plate, AS−interface)

� On the optional pneumatic air supply plate, at a maximumbetween every manifold block

Port (12/14):

� On the right−hand end plate

3. Installation


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

The pilot control of the solenoid coils uses an internal or ex�ternal pilot air supply depending on the position of the selec�tor on the right−hand end plate. The type of pilot control setfor your MPA−F valve terminal can been recognised from thefollowing diagram:

Selector position on the right−hand end plate Pilot control variants

1 Right−hand end plate of the MPA−F valve terminal

2 Selector seal position with internal pilot air supply

3 Selector position for operating the valve terminal with an internal pilot air supply

4 Selector retaining screw (tighteningtorque 4 Nm (±20%))

1 2 3 4 Operating with external pilot air supply:

1 Right−hand end plate of the MPA−F valve terminal

2 Selector seal position with an external pilot air supply

3 Selector position for operating thevalve terminal with an external pilotair supply

4 Selector retaining screw (tighteningtorque 4 Nm (±20%))

Tab.�3/1: Selector identification position, depending on the type of pilot control

3. Installation


Internal pilot air supply If the operating pressure lies between 3 ... 8 bar, you canoperate the pilot control of the solenoid coils with an inter�nally branched pilot air supply.

Note· The internal pilot air supply is branched centrally fromsupply channel (1) for all solenoid coils. This also applieswhen the MPA−F valve terminal is operated with severalpressure 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 solenoid coils must be operated with anexternal pilot air supply.

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

· The external pilot air supply is supplied centrally for allsolenoid coils via pilot connections (12/14) on the right−hand end plate. This is the case even if the MPA−F valveterminal is operated with different pressure zones.

· Set the external pilot air supply to correspond to theoperating pressure at which these valves are operated(see diagrams in appendix A Fig.�A/1 and Fig.�A/3).

3. Installation


3.3.2 MPA−F valve terminal with pressure zone separation

Basic information on pressure zone separation is provided inchapter 1, section �Pressure zone separation".

Note· If the MPA−F valve terminal is also fitted with othervalves, operate valves with Ident. code I (2 x 2/2−wayvalves) in a separate pressure zone with a separate ex�haust duct (5).

Note the following in the case of type MPA−F valve ter�minals which are operated with an internal pilot air supplyand which have several pressure zones:

· Internal pilot air supply is branched centrally from sup�ply channel (1) for all solenoid coils. This also applieswhen the MPA−F valve terminal is operated with severalpressure zones (see Fig.�3/3).

· The pressure zone, which is supplied via supply connec�tion (1) of the pneumatic interface or the multiple con�nector plate, must be operated with a pressure between3 ... 8 bar.

The following diagrams show as an example the assignmentof the supply and exhaust connections to the valves on anMPA−F valve terminal with blocked channels (1), (3) and (5).

A pressure zone seal and a pneumatic air supply plate is re�quired for every pressure zone (see Fig.�3/3).

The connections (1) or (3/5) are:

� for the pressure zone on the outside left of the pneumaticinterface or on the multiple connector plate.

3. Installation


� for all other pressure zones, on the pneumatic air supplyplate lying within the corresponding pressure zones. Theposition of the air supply plate within the pressure zone(left, centre or right) is optional.

By fitting an additional pneumatic air supply plate within apressure zone you can feed additional supply air or extractexhaust air.

Contents of this chapter This chapter explains how to commission the valve terminaltype MPA−F. This especially includes:

� Instructions on building up pressure in the complete supply

� Operating the manual overrides

� Checking the valves and the valve−actuator combination

� The assignment of LEDs and manual overrides to the sole�noid coils

� Function impairments

� Operating states of the pneumatic system

Additional information Commissioning of the CPX terminal is described in the ap�propriate description for the CPX bus node (see the systemdescription of your CPX terminal, table �Descriptions of theCPX terminal").

4. Commissioning


4.1 General information

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 on building uppressure in the complete supply.

4.1.2 Pressure increase in the complete supply

WarningIf the pressure build−up of the pilot air supply is too slowor delayed, this may cause the actuators to performsudden unexpected movements under the following condi�tions:

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

� if 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 an external pilot air sup�ply (3 ... 8 bar). Branch the pilot air supply before thesoft−start valve (see Fig.�4/1).

4. Commissioning


The pilot air supply must reach a pressure of 3 ... 8 bar assoon as it is switched on. Otherwise there is no guaranteethat the valve will switch directly (see Fig.�4/1). 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).

4.2 Manual override

You should use the manual override especially when commis�sioning the pneumatic system, in order to check the functionand operation of the valve or the valve−actuator combination.

By actuating the manual override, you can switch the valvewithout an electric signal. You only need to switch on thecompressed air supply.

The manual override has been designed to be used as fol�lows:

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

Commissioning of the CPX terminal is described in the ap�propriate description for the CPX bus node (see the systemdescription of your CPX terminal, table �Descriptions of theCPX terminal").

4. Commissioning


WarningBefore actuating the manual override:

Uncontrolled actuation of solenoid coils can cause theactuators to perform sudden unexpected movementswhich may cause personal injury and material damage.

· Disconnect the power supply for the solenoid coils at the relevant connections on the MPA valve terminal.

You will thereby avoid undesired actuation of the solenoidcoils.

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.

1. Switch on the compressed air supply.

4. Commissioning


2. Check the functioning and operation of each individualvalve−actuator combination by actuating the manual overrideas 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. 2.5 mm) for actuat�ing the manual override.

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

3. With the locking function of the manual override: Aftertesting the valves, make sure that all manual overrideactuations 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.

5.3.4 Replacing electronics modules

The MPA−F valve terminal is mounted with one electronicsmodule per manifold block. It provides the following numberof contacts between the electrical linking and the solenoidcoils, depending on the size of the manifold blocks.

� for size MPA1 contacts for 4 valve positions

� for size MPA2 contacts for 2 valve positions

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

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

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

· Do not touch any components

· Observe the handling specifications for electrostaticsensitive devices.

· Discharge yourself before installing or removing sub−assemblies to protect the sub−assemblies from staticdischarges.

CautionReplace an electronics module only by an electronics mod�ule of the same type.



Before mounting the electronics module

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

Electronics module for the MPA−F valve terminal with CPXterminal

CautionDamage to components and functional damage

It is not permitted to supply MPA pneumatic modulesequipped with electronics module and that have a com�mon circuit via interlinking blocks of type CPX−GE−EV−V..(valve supply) or 5−pin system supply (type CPX−GE−EV−S−7/8−5POL).

· If your MPA pneumatics are mounted with electronicsmodules of type VMPA1−FB−EMS−... or VMPA2−FB−EMS−..., you must supply the MPA−F pneumatics exclus�ively via a four pin system supply module type CPX−GE−EV−S or CPX−GE−EV−S−7/8−4POL.

Note the overview in Tab.�5/2.



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

MPA electronics module... Permitted supply modules

...with common circuits:� VMPA1−FB−EMS−...� VMPA2−FB−EMS−...

MPA−S valve terminal with CPX terminal:� System supply (M18, 4−pin): Type CPX−GE−EV−S� System supply (7/8", 4−pin): Type CPX−GE−EV−

1) If a 4−pin system supply is used, the electrical isolation will be removed.

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

In the case of MPA electronics modules with separate circuitsof type 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:

� Interlinking block with valve supplies (M18 or 7/8"): Type CPX−GE−EV−V..

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

� Electrical supply plate MPA: Type VMPA−FB−SP−...−V−...



NoteThe electrical function of an MPA−F pneumatic module isdetermined by the electronics module used, e.g.:

� Electromagnetic compatibility (EMC)

� Switching off the valve supply voltage at all poles

You must observe the instructions in the manual for theCPX I/O modules if you wish to mount an electronics mod�ule of a different type.

Recommendation:

Replace only with electronics modules of the same type.

The electronics modules type VMPA...−FB−... support the con�trol of two valve solenoid coils per valve position.

5.4 Converting the MPA−F valve terminal

The following conversion work can be undertaken on theMPA−F valve terminal:

� Conversion of the MPA−F valve terminal to different pressurezones

� Adding valve positions (manifold blocks)

5.4.1 Conversion to different pressure zones

Basic information on pressure zone separation is provided inchapter 1, section �Pressure zone separation".

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

Electrical connection variants of the valve terminal

CPX terminal MPM connection

Pressure zones 1 ... 16 1 ... 12

Tab.�5/6: Number of pressure zones

The pressure zones are formed by using either special mani�fold blocks or special separating seals (see chapter 1, section�Pressure zone separation").

The following section describes the formation of pressurezones by using separating seals.

For converting the valve terminal, you will require the follow�ing components for each pressure zone:

� Separating seal with pressure zone separation (see chapter 1, Fig.�1/9)



� If not already provided, one of the following pneumaticsupply plates with interlinking board, exhaust plate or flatplate silencer:

5.4.2 Adding valve positions

You can easily adapt the MPA−F valve terminal to the require�ments of your machine or system by adding valve positions.The smallest extension unit is a manifold block with 4 valvepositions (MPA1) or 2 valve positions (MPA2).


The valve terminals can be configured with as many manifoldblocks as there are addresses available (see Tab.�5/8). Withthese valve terminals, the maximum number of solenoid coilswhich can be actuated by the multi−pin connection is limitedto 24 addresses.

If only equipped with sizes MPA 1 or MPA 2 and valves withthe same number of solenoid coils, this will result in the fol�lowing maximum number of manifold blocks:

MPA−F valve terminal Valve positions permanifold block (n1)

Coils per valve position(n2)

max. 1)

MPA1 4 1 6

2 3

MPA2 2 1 12

2 6

1) Maximum number of manifold blocks when exclusively equipped with one size and with valves having the same number of solenoid coils

Tab.�5/8: Maximum number of manifold blocks

With 24 controllable solenoid coils the maximum number ofmanifold blocks (Xmax) can be calculated as follows:

Xmax � 24�n1� n2�




NoteA maximum of 16 MPA−F manifold blocks are permitted onthe MPA−F valve terminal with CPX terminal.
