1.1 The valve terminal MPA−L

Festo supports your automation tasks at machine level withthe valve terminal MPA−L. The modular structure of the valveterminal MPA−L enables you to match this valve terminal opti�mally to your machine or system.

The valve terminal MPA−L provides the following connections:

� Common ducts for supply and exhaust air

� Electric signals from all solenoid coils

Working lines (2) and (4) are provided for each valve positionon the individual pneumatic sub−bases. The valves are sup�plied with compressed air (operating pressure and pilot pres�sure) via the common channels and connections in the basiccomponents. The exhaust air (from the valves and the pilotexhaust air) is also exhausted via these common channels.Further components for compressed air supply are also avail�able, e.�g. in order to supply pressure zones.

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

� The valve terminal MPA−L has a lower power consumption

� The power unit for the voltage supply to the valve ter�minal MPA−L can be designed more economically depend�ing on the individual case

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



1.2 Valve terminal design

The valve terminal MPA−L consists of the following pneumaticand electric components: The most important componentsare shown in Fig.�1/1.

The following operating modes can be used � independentlyof valve type:

� Standard operation with one or more pressure zones

� Reversible operation with compressed air supply via connections (3), (5) and exhaust via port (1)

� Low−pressure operation at 0 ... 3� bar

� Vacuum operation at −0.9 ... 0� bar

1.3 Electrical multi−pin connection

The electrical connection of the solenoid coils is made cen�trally via a multi−pin plug in the left−hand end plate, which is available in various variants for the he valve terminal MPA−L(see Tab.�1/1). One or two solenoid coils per v alve positioncan be controlled. Each solenoid coil occupies one pin of themulti−pin plug.

1.3.2 Versions of the IP protection class

For variants with sub−D plugs the multipin connection can be implemented with various cover types (see Tab.�1/2).

Multipin sub−base Cover types for sub−D plug

IP65 cover:closed cover, Protection class IP65, with pre−prepared cableExclusively for the sub−D plug with 25−/44 pins.

Further information on the valves can be found in Appendix�B.

1.5.2 Main and additional power supply

The main supply of the valve terminal with operating pressurecan be made via a pneumatic supply plate (see Fig.�1/3) orvia the right−hand end plate with lateral ports (Tab.�1/4below).

Fig.�1/3: Pneumatic supply plate

The pneumatic supply plate can also be used for additionalpower supplies. These are, for�example, necessary in the caseof valve terminals operated with several pressure zones orwhen a large number of valves on the valve terminal areswitched simultaneously to flow.

1.5.3 Pilot air supply

The pilot control of the solenoid coils is supplied with internalor external pilot air. This pilot air is made available for thecomplete valve terminal (also via the pressure zones) via theright−hand end plate (see Tab.�1/4).

A selector plate on the right−hand end plate makes it possibleto branch the pilot air internally from the supply port (1) or totake it from the separate supply via the port (12/14).

NoteInternal pilot air supply is only permitted if the operatingpressure of the last pressure zone (at the right−hand endplate) is between 3 and 8� bar .

The operating pressure can bebelow 3�bar and above 8�bar, so long as separately controlledpilot pressure (3�...�8�bar) is available.

Tab.�1/5: Features of the pilot control variants

1.5.4 Exhaust air

The exhaust (3) and (5) of the air is exhausted together viathe flat plate silencer and the exhaust plate or separately viathe right−hand end plate with ports at the side.

The pilot exhaust air (82/84) is led to a connection on theright−hand end plate and can either be ducted there or ex�hausted via a silencer.

1.5.5 Sub−bases and pressure zone separation

The valves of valve terminal MPA−L are supplied pneumati�cally via the sub−bases and via the electronic module that isinstalled in the sub−base (see Fig.�1/4).

In addition to the individual sub−bases there are also the 4 offsub−bases with common 4 off electronic module.



1 Sub−base

2 Electronicsmodule

Fig.�1/4: Sub−base with electronic module

In addition valves within a valve terminal MPA−L can be sup�plied with different pressures by creating different pressurezones. The separation of the pressure zones is achieved byspecial sub−bases. In each case the valve mounted to theright of the special sub−base belongs to the next (following onto the right) pressure zone, which is the valve mounted on thespecial sub−base in the current pressure zone.

The sub−bases with integrated pressure zone separation are in various versions with corresponding identification (see Tab.�1/6):



Sub−base design MPA1

Supply duct (1) separated Type: VMPAL−AP−...−T1

Exhaust ducts (3) and (5) separated Type: VMPAL−AP−...−T135

Supply channel (1) and exhaustducts (3) and (5) separate

Type: VMPAL−AP−...−T135

Tab.�1/6: Variants of the sub−bases with integrated pressure zone separation

Pressure zone separation of the pilot channels (12) and (14)is not provided, as on the valve terminal MPA−L the air supplyfor the pilot control of the valves is supplied centrally via theright−hand end plate.

1.5.6 Vertical stacking

You can fit further pneumatic components to each valve position between the sub−base and the valve. These verticalstackings enable you to implement certain additional func�tions as desired.



Tab.�1/7 shows the main structure and possible componentsof the vertical stacking.

Tab.�1/7: Components of the vertical stacking

1.5.7 Pressure regulating plates

Mode of operation A pressure regulator plate with adjustable pressure regulatorcan be installed between the sub−base and the valve in orderto control the force of the connected actuators. This pressureregulator maintains an essentially constant output pressure(secondary side) independent of supply pressure (primaryside) and air consumption.

Identification The pressure regulator plates of the vertical stacking aremarked on the valve terminal MPA−L with the Ident. code. This is marked on the side of the pressure regulator plate.Using Tab.�1/8 you can identify the pressure regulator plates.

Tab.�1/8: Identification of the regulator plates in the type code

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

P pressure regulating valve(identification PF, PA)

Supply process The P pressure regulating valve regulates the pressure infront of the valve in duct (1)/(P). This provides the same regulated air pressure in channels (2) and (4).

Exhaust procedure The exhaust flow is from channel (2) to channel (3) and fromchannel (4) to channel (5) through the pressure regulatorplate to the valve terminal.

The advantages of this pressure regulating valve are:

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

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



Application examples:

� An equal air pressure is required at working lines (2) and (4).

� A lower air pressure (e.g.�3�bar) than the operating pres �sure present on the valve terminal (e.g.�8�bar) is required.

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

Supply process The work or operating pressure regulator regulates the relevant pressure of the air (see 1 in Tab.�1/9) when thepressure medium has flowed through the valve. The exhaustair is passed through the pressure regulator plate and isswitched to the relevant exhaust duct in the valve (see 2in Tab.�1/9).

Exhaust procedure During exhausting the air is passed unregulated through thevalve and the pressure regulator plate to the valve terminal(see 3 in Tab.�1/9).

Tab.�1/9: Mode of operation of the A and B pressure regulator

Restrictions:

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



� The pressure of the air in channel (2) can only be set andread on the pressure gauge when the valve is in theswitch position: Flow from (1) to (2).

Application examples:

� If different air pressures are required at ports (2) and (4)instead of the operating pressure of the valve terminal.

Fig.�1/5 shows the following switching position of the operat �ing pressure regulator:The air is passed from channel (1) through the pressure regu�lator plate and the valve to the operating pressure regulator,where it is regulated and then passed to connection (2) of the sub−base. The unregulated exhaust air is then fed viachannel (4) through the pressure regulator plate and then tochannel (5) and vented.

Information on the electrical connection and display compo�nents of the CPX bus node is provided in the corresponding�Electronics description" (see the system description for yourCPX terminal, table �Descriptions of the CPX terminal").



1.7.1 �Identification system" (as per catalogue)

Alternatively or supplementary to the inscription labels attached to sub−bases, inscription labels with large surfaceareas can be attached to the pneumatic interface.

Information about corresponding accessories can be found in the Festo Catalogue (see www.festo.com\catalogue).

1.7.2 Manual override (MO)

The manual override (MO) enables the valve to be actuatedwhen not electrically activated or energised. You only need to switch on the compressed air supply. You should use themanual override especially when commissioning the pneu�matic system, in order to check the function and operation of the valve or the valve−actuator combination.

Non−detenting actuation The valve is activated by pushing the manual override. On release of the manual override the spring−loaded valve switches automatically from the switch position to the normally open position.

Detenting actuation By turning the manual override clockwise the switch positioncan be detented. It remains actuated until it is reset by hand.

These basic functions of the manual override can be changedby installing a corresponding manual override cover cap:With a cover for manual override, code: N, locking is pre�vented. The manual override can then only be operated bynon−detenting.With a cover for manual override, code: V, the manual over�ride can be safeguarded against undesired operation

The operation of the manual override is described inChapter�4.2.



NoteA manually actuated valve (by manual override) cannot beactuated electrically. Conversely, an electrically actuatedvalve cannot be activated using the mechanical manualoverride. The valve only returns to the rest position whenboth actuations are reset.

1.7.3 Pressure regulator

2.1 General instructions on mounting/dismantling

WarningUncontrolled movements of the connected actuators andloose tubing can cause injury to persons and/or damage toproperty.

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

� Compressed air supply

� The operating and load voltage supplies.

NoteHandle all modules and components of the valve terminalMPA−L with great care. Note especially the following:

� The specified torques must be complied with.

� Electrostatically sensitive devices.Therefore, do not touch any contact surfaces.

NoteMount the valve terminal MPA−L so that there is sufficientspace for heat dissipation and ensure that the maximumlimits for temperatures are observed (see �Technical specifications").

2. Mounting


2.2 Installation/removal on an H−rails

The valve terminal MPA−L is suitable for fitting onto an H−rail(support rail as per EN 60715). There is a guide groove on theback for hanging the valve terminal onto the H−rail.

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

� 0.15�mm Amplitude at 15 ... 58� 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 (see Tab.�A/2 in Appendix�A).

CautionH−rail mounting without an H−rail clamping unit is not per�mitted.

· Secure the valve terminal MPA−L using the H−rail clamping:against sliding down with the retaining screw intended forthis purpose (see Tab.�2/1 and Fig.�2/1)� against unintentional loosening/opening.

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

� for valve terminal MPA−Ls with multi−pin plug connection:Mounting, type CPA−BG−NRH. This kit contains 2 M4x10screws and 2 clamping elements.

� for valve terminal MPA−Ls with CPX terminal: Mounting,type VMPAF−FB−BG−NRH. This set consists of 3 clampingcomponents, two M4x12 screws and one M4x10 screw.

3.1 Compressed air preparation

CautionUnfiltered or incorrectly lubricated compressed air willreduce the service life of the valve terminal.

3.1.1 Operation with unlubricated compressed air

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

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

� When using mineral oils (e.g. HLP oils to DIN� 51524,parts�1 to 3) or similar oils based on poly−alpha−olefins (PAO), the maximum residual oil content of5�mg/m3 must not be exceeded (see ISO�8573−1 Class�4).

This avoids operative malfunction of the valves.

Excessive residual oil is not permissible irrespective of thecompressor oil, as otherwise the basic lubrication will bewashed out with time.

3.1.2 Operation with lubricated compressed air

Operate system equipment with unlubricated compressed air,if possible. This is better for the environment. Festo pneu�matic valves and actuators have been designed so that, ifused as intended, they will not require additional lubricationand will still achieve a long service life.

3. Installation


CautionOperation with lubricated compressed air will cause thelife−time lubrication, which is necessary for unlubricatedoperation, 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 unlubricated compressed air. If possible, do not operate all of your equipment with lubricatedcompressed air. If possible, always install the lubricators directly upstream of the consuming actuators.

CautionUnsuitable additional oil and an excessive oil content inthe compressed air reduce the service life of the valve ter�minal.

� Use Festo special oil OFSW−32 or the alternatives listedin the Festo catalogue (as specified in DIN�51524−HLP32;basic oil 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 setting is correct (see following section)

This avoids operative malfunction of the valves.

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

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

Proceed as follows, in order to check the service units withrespect to condensate and lubricator settings two times perweek.

3. Installation


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

2. Ascertain the valve terminal which controls this cylinder.

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

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

5. Let the system run for a short period.There must be only a slight yellow colouring on the card�board.

If oil droplets appear, this is an indication that too much oilhas been used. Another indicator is the coloration or thecondition of the exhaust air silencer. Distinctly yellow colour�ing of the filter element or drops of oil on the silencer indicatethat the lubricator setting is too high.

3. Installation


3.2 General instructions on installation

WarningUncontrolled movements of the connected actuators andloose tubing can cause injury to persons and/or damageto property.

Before carrying out mounting, installation and mainten�ance work, switch off the following:



Pay attention to the following:The components of the valve terminal contain electrostaticallysensitive components. The components will be damaged if you touch the contact surfaces of the plug connectors or if you do not observe the handling specifications for electro−statically sensitive devices.

NoteHandle all modules and components of the valve terminalMPA−L with great care.

Note especially the following:

� Screws must be fitted accurately (in particular to avoiddamage to threads on plastic housing parts) andscrewed in by hand

� The specified torques must be observed

� Clean connecting services (avoidance of leaking andcontact faults) and intact seals and sealing surfaces

� Close unused connections with blanking plugs to avoidcontamination and maintain reliability.

back pressure When exhausting large volume actuators or if the exhaustperformance is too small, back pressures can build up in thevalve terminal exhaust ducts. The back pressures can lead topneumatic actuation of other valves, especially with un�switched 3/2−way valves that are normally closed.

3. Installation


To avoid back pressures:

· Optimise the ventilation and exhaust performance of the valve terminal e.�g. by using lar ger pipe diameters oradditional compressed air supply via pneumatic supplyplates with exhaust via silencers and exhaust plate.

· Separate exhaust ducts by using pressure zones ifnecessary (see Chapter� 1.5.3).

3.3 Connecting the valve terminal MPA−L

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

� To the pneumatic supply plate, type VMPAL−SP

� To the right−hand end plate, type VMPAL−EPR−SP

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

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· Internal pilot air supply is branched centrally from sup�ply connection�(1) for all solenoid coils. When operatingthe valve terminal with several pressure zones the inter�nal pilot air supply is taken from the pressure zone,which is directly adjacent to the right−hand end plate(see Fig.�3/1 and Fig.�3/2).

3. Installation


External pilot air supply If the operating pressure lies below 3�bar or abo ve 8�bar,pilot control of the solenoid coils must be operated with an external pilot air supply.

Note· Use preferably closed−loop regulated external pilot air.Reliable faultless operation of the valve terminal is thenpossible, e.�g. even with fluctuating operating pressure.

· The external pilot air supply is supplied centrally for allsolenoid coils via pilot connections�(12/14) on the right−hand end plate. This also applies when the valve ter�minal is operated with two pressure zones.

· For external pilot air supply the pilot air pressure mustbe adapted to the operating pressure, but only withinthe values of 3� ...�8�bar .

The conversion between the internal and external pilot airsupply is described in Chapter� 5.3.6.

3.3.2 Valve terminal MPA−L with pressure zone separation

The pressure zones are separated from each other by specialsub−bases (see Chapter� 1.5.5). Each pressure zone must besupplied by pneumatic supply plate and via a right−hand endplate with side connections with compressed air. The positionof the supply plate within the pressure zone (left, centre orright) is arbitrary.

By fitting a second supply plate within a pressure zone youcan provide additional supply air and exhaust air to optimisethe ventilation and exhaust performance of the valve ter�minal.For each additional pressure zone a special sub−base is re�quired for separation and a special pneumatic supply plate isrequired for supply (see Fig.�3/1 and Fig.�3/2).

3. Installation


The following diagrams show as an example the assignmentof the supply and exhaust ports to the valves on a valve ter�minal with three and four pressure zones and blocked chan�nels (1), (3) and (5) and with blocked channel (1).

4. Commissioning


4.1 General Information

4.1.1 Prior to commissioning

· Switch off the power supply before connecting or discon�necting plug connectors (otherwise functional damage).

· Only commission a valve terminal that has been mountedand 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 coils are constantly under stress

· Note the specifications concerning the medium.

4.1.2 Pressure build−up in the overall 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 connected via a soft−startvalve (gradual pressure build−up) and

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

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

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

4. Commissioning


The pilot air supply must reach a pressure of 3 ... 8 bar.Otherwise it is not ensured that 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 gradual pressure build−up of the overall supply doesnot affect the actuator in that case. The actuator would reactsuddenly (e.�g. a cylinder would extend or retract suddenly ,depending on the valve function).

4.2 Checking the valves and the valve/actuator combination

The valve terminal MPA−L should be commissioned as follows:

Commissioning variants Activity

Preliminary test of the pneuma�tic tubing connection

Test the valve−actuator combina�tion by means of the manualoverride

Complete commissioning of theoverall system

Installing and connecting theoverall system.Program control via PLC/indu�strial PC.

Tab.�4/2: Commissioning variants

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

Commissioning of the CPX terminal is described in the appropriate description for the CPX bus node (see CPX system description, table �Descriptions of the CPX terminal").

4. Commissioning


WarningBefore actuating the manual overrides:

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 valve terminal MPA−L.

This prevents accidental actuation of the solenoid coils.

Before switching on the power supply:

During commissioning, manual overrides that are in theswitched state can cause actuators to perform suddenunexpected movements. These movements can cause injury to persons and damage to property.

· Make sure that all manual overrides are reset to theirinitial position.

You will thereby avoid undefined switching states of thevalves.

WarningBefore testing the valve/actuator combination:

ID code: I, Function: 1)

� Two monostable 2/2−way valves, both valves normally closed, valve on controlside 14 reversible

� Pneumatic spring return� With dual−pressure operation:

� Supply operating pressure via connection 1� Operating pressure can be separately supplied at connection (3/5).

� Solenoid coil 14 switches the operating pressure from connection (5) to connection (4)

� Solenoid coil 12 switches the operating pressure from connection (1) to connection (2)

� With vacuum operation:� Feed operating pressure via connection (1)� Feed vacuum via connection (5)� Solenoid coil 14 switches the vacuum to connection (4)

� At connection 4 or in tubing (4) a filter is provided, so that no dirt can enter the valve.

� Solenoid coil 12 switches the operating pressure to connection (2) (e.g. for an ejector pulse in vacuum operation)

� Establish a connection using a T−piece for an ejector pulse between connections (2),(4)and the vacuum generator

1)Note: If this 2/2−way valve (Ident. code I) is also operated with other valves on the MPA−L valve terminal, then this 2/2−way valve must be operated in a separate pressure zone with a separate exhaust air channel (5).
