1.1 The VTSA/VTSA-F valve terminal

Festo supports your automation tasks at machine level withthe VTSA/VTSA-F valve terminals. The modular structure ofthe valve terminal enables you to optimally customise it toyour machine or system.

The valve terminal pneumatics establish the following con-nection:

– common ducts for supply and exhaust air

– electric signals of all solenoid coils.

The working ports (2) and (4) are provided for each valveposition on the individual manifold sub-bases. The valves aresupplied with compressed air (operating pressure and pilotpressure) via the common channels and connections in thepneumatic supply plates. The exhaust air (from the valvesand the pilot exhaust) is also exhausted via these commonchannels and connections.

Dependent on its width, the valve terminal can be supplemen-ted by additional pneumatic supply plates, such as to supplypressure zones.

The function range at each valve position can be extended bymeans of additional vertical stacking components, e.g. ex-haust air flow control or pressure regulation.

Versions The valve terminal is available in a VTSA and VTSA-F design.The VTSA-F valve terminal provides the mounted valves witha higher flow volume.

The pneumatic supply plate can also be used for additionalsupply. This is necessary, for example, if the valve terminal isoperated with several pressure zones or if many valves simul-taneously are switched to flow or exhausted on the valve ter-minal.



1.2.2 Valves

The VTSA/VTSA-F valve terminal can be equipped with thefollowing valves:

– 5/2-way valves, (monostable or bistable)

– 5/3-way mid-position valves

– 2x2/2-way valves

– 2x3/2-way valves

– reversible 2x3/2-way valves.

Dependent on the valve type, the VTSA/VTSA-F can be oper-ated as follows:

– standard operation (- 0.9 … 10 bar)

– reversible operation (- 0.9 … 10 bar).The compressed air supply for reversible operation of theVTSA… is provided via ports (3) and (5).The exhaust procedure is effected via port (1)(� also see section 3.8 and 3.8.1).

All 5/2-way valves and 5/3-way mid-position valves can beused in all operating modes.



Identifying the valves The valves are labelled with an Ident. Code. You will find theIdent. Code on the top of the valves.

operation (� instructions in the sections 3.6 Pressure zone separation, 3.9 Vacuum/low

pressure operation, as well as in Appendix B1, Tab. B/5).

Tab. 1/6: Identification of the valve function in type code (part 2)

5/2-way valves with piston position sensing

The monostable 5/2-way valves with ID code SO or SQ (width26 mm) have a piston position sensing. An inductive sensor(N/C contact) monitors the neutral position of the pistonspool. The sensor has a PNP or an NPN output. The valve isactuated via a multi-pin or fieldbus connection.



5/3-way valve with extended function

The 5/3-way valves with Ident. Code SA or SB have a signal-storing function in switching position 14. If there is no longera signal on coil 14, the switching position 14 remains as is,since there is no spring return on control side 12.

The 5/3-way valve with Ident. Code SE has a signal-storingfunction in switching position 12. If there is no longer a signalon coil 12, the switching position 12 remains as is, since thereis no spring return on control side 14.

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

1.2.3 Manifold sub-bases

The number of electrically controllable valve positions de-pends on the manifold sub-bases and the electrical connec-tion used (� Tab. 1/2 ... Tab. 1/4).

If only manifold sub-bases that support the control of twosolenoid coils per valve position are used, any type of valvecan be placed in any valve position.

If, on the other hand, only manifold sub-bases that controlonly one solenoid coil per valve position are used, the valveterminal can only be equipped with monostable 5/2-wayvalves (Ident. Code M, O, SO or SQ).

1.2.4 Pilot control

The pilot control of the solenoid coils is supplied with internalor external pilot air. This pilot air is made available for theentire valve terminal (also across pressure zones) through thesoft-start valve or the various right end plate variants. Thefollowing applies:

– the valve terminal is always supplied with internal pilot airthrough the soft-start valve

– you can choose whether the valve terminal should besupplied with internal or external pilot air via the corres-ponding right end plate variants.



There are two groups of end plates with the VTSA/VTSA-Fvalve terminal.

– For end plates with axial ports, the type of pilot air supply(internal or external) is determined by the design.

– The following can be selected for the selector-end plate:

– the type of pilot air supply (internal or external)

– the manner of venting the pilot exhaust air (viaduct (12) or at the valve).

You can ascertain the end plate with which your VTSA/VTSA-Fvalve terminal is fitted by means of the following table. Con-version between internal and external pilot air supply is de-scribed in section 5.6.2.

1.2.5 Pressure zone separation

Using special seal plates, you can divide the VTSA/VTSA-Fvalve terminal into pressure zones (� 3.8). The followingducts can be separated with the seal plates:

– supply duct (1) only

– supply duct (1) and exhaust ducts (3) and (5)

– exhaust ducts (3) and (5) only.

In the VTSA/VTSA-F valve terminal, the pilot control for thevalves is supplied with pilot air centrally via the right endplate or via the soft-start valve. A pressure zone separation ofpilot ducts (12) and (14) is therefore not possible.

The number and type of pressure zones of your valve terminalcan be identified via the inscription on the manifold sub-bases (� Tab. 1/9). Alternatively, the pressure zones can alsobe identified via the markings on the seal plates (� Fig. 1/4).

Tab. 1/10: Components of the pneumatic module of the VTSA/VTSA-F valve terminal



The vertical stacking components on the VTSA/VTSA-F valveterminal are marked by type codes. The code is printed onthe side of the component. An identifier within the type codeindicates the function of the component; for example, in thetype code VABF-S4-1R1C2-C-10:

– identification R1means the component is a P-pressureregulator

– identification 10means the control range of the pressureregulator extends to 10 bar.

In the sales documentation and in the Festo Configurator, thecomponents are marked with an ID code.

You can identify the vertical stacking components with the aidof the following table. Not every pressure regulator functionis available for all widths.

Note• Use a maximum of one vertical stacking component pervalve position if vibration and shock of severity level 2 isexpected (� Tab. A/4).

1.2.7 Pressure regulator plates

Mode of operation To influence the force of connected actuators, a pressure reg-ulator plate with adjustable pressure regulating valve can bebuilt in between the manifold sub-base and valve. This pres-sure regulating valve maintains an essentially constant out-put pressure (secondary side) independent of supply pres-sure (primary side) and air consumption.

The following descriptions of the pressure regulator functionsare provided using the example of the pressure regulatorVABF-S4-1…C2-C-... (VTSA pressure regulator ofwidth 18 ...52 mm).

P-pressure regulator (identifier R1-...-6and R1-...-10)

Pressurizing process The P-pressure regulator regulates the pressure in front ofthe valve in duct (1) (P). This provides the same regulatedworking air pressure in channels (2) and (4).

Exhaust process: The exhaust flow in the valve is from channel (2) to chan-nel (3) and from channel (4) to channel (5).



The advantages of this pressure regulator are:

– The pressure regulator is not affected by exhausting,since the pressure is regulated upstream of the valve.

– The pressure regulator can be adjusted at any time, asthe operating pressure is always present.

Application example:

– An equal output pressure is required at ports (2) and (4).

– A lower air pressure (e.g. 3 bar) is required than the oper-ating pressure present at the valve terminal (e.g. 8 bar).

AB-pressure regulator (identifier R4-...-6and R4-...-10)

Pressurizing process The AB-pressure regulator regulates the air pressure inducts (4) (A) and (2) (B) after the pressure medium haspassed through the valve.

Exhaust process During the exhaust process, the exhaust flows in the valveunregulated from duct (2) to duct (3) and from duct (4) toduct (5) via the pressure regulator.

Restrictions:

– The exhaust flow is restricted by the pressure regulatingvalve.

– The pressure regulator cannot be adjusted in the exhaustposition. For example, the pressure regulator for duct (4)cannot be adjusted when the valve is pressurised in theswitching position from duct (1) to duct (2) and ventedfrom duct (4) to duct (5).



Application examples:

– If two different working pressures are required atports (2) and (4) instead of the operating pressure of thevalve terminal.

– If the reversible pressure regulating valve cannot be used.For example, when 2x2/2-way valves or 2x3/2-way valveswith ducted solenoid exhaust (82/84) or when a flow con-trol plate is used.

Fig. 1/5 shows the following switching position of the B-pres-sure regulator:The working air is passed from duct (1) through the interme-diate plate and the valve to the B-pressure regulator, where itis regulated and then passed to port (2) of the manifold sub-base. The exhaust is passed via duct (4) to pressure regulat-ing valve A and then via the valve to duct (5).

Fig. 1/5: AB-pressure regulator

Reversible AB-pressure regulator (identifier R5-...-6and R5-...-10)

Pressurizing process With the reversible pressure regulator, the air (duct (1)) issplit and routed directly to both pressure regulators. In eachcase the regulated air is present in ducts (3) and (5) on thevalve. The valve is thus operated in reversible mode(� Fig. 1/6). This means:

– duct (3) routes the working pressure to port (2)

– duct (5) routes the working pressure to port (4).



Exhaust process Venting occurs in the valve from duct (4) or duct (2) toduct (1) and in the intermediate plate guided to duct (5) orduct (3) in the manifold sub-base.

Advantages compared with the AB-pressure regulator:

– Faster cycle times.

– 50 % higher exhaust flow rate, as air is not vented via thepressure regulator. The load on the pressure regulator isalso reduced.

– No quick exhaust valves are required. The exhaust is duc-ted completely via the valve terminal.

– Operating pressure is always present at the pressure reg-ulator, as the pressure is regulated upstream of the valve.In other words, the regulator can always be adjusted. Inthe case of the AB-pressure regulator, the valve mustswitch for this.



Disadvantages compared with the AB-pressure regulator:

– No use of 2x2/2-way valves (Ident. Code: CV, VV) and2x3/2-way valves (Ident. Code: K, H, N) is possible in com-bination with ducted solenoid exhaust (82/84), as revers-ible pressure is present at the valve interface.

– No practical combination with an intermediate throttleplate possible.

Application examples:

– When, instead of the operating pressure of the valve ter-minal, two further different pressures are required inducts (2) and (4).

– When fast venting is required.

– When the pressure regulator must always be adjustable.



The example below shows the following switching position:The air in duct (1) is passed in the pressure regulator plate topressure regulators A and B, regulated there and then passedto ports (3) and (5) on the valve. In the valve, the air is routedto port (2) of the manifold sub-base. The exhaust is conduc-ted via duct (4) in the pressure regulator plate and split thereto ducts (3) and (5) and exhausted.

Flow control plate

This plate is used in vertical stacking for exhaust air flow con-trol in ducts (3) and (5) in order to adjust the speed of thecorresponding actuator.

Vertical pressure shut-off plate

NoteThe vertical pressure shut-off plates are only intended incombination with VSVA valves from Festo. Duct 12 is notblocked in the vertical pressure shut-off plate.

This plate can be used to cut off the corresponding valve invertical stacking from the terminal's operating and pilot pres-sure. Both duct (1) and duct (14) are shut off at the sametime. This means that the VSVA valve can be removed withoutshutting off the pressure. When operating a valve terminalwith a vertical pressure shut-off plate, pay attention to theinstructions in section 3.4.2.

Vertical supply plate

This plate can be used to supply a valve in vertical stackingwith an individual operating pressure and pilot air supplyindependently of the operating pressure of the terminal. Theinternal pilot air is branched from duct (1) for this valve posi-tion.

Soft-start valves with piston position sensing

The purpose of the VABF-S6-1-P5A4-… soft-start valve (design� Appendix, Tab. B/6) is to slowly and safely build up thesupply pressure in duct (1) of the valve terminal or to quicklyvent duct (1).



Fig. 1/7: Soft-start valve

The optimum pressure build-up and filling time required bythe application for each pressure zone is configured directlyon the valve terminal.

The VTSA/VTSA-F valve terminal can either be operated withan internal pilot air supply via the soft-start valve or with aninternal or external pilot air supply via the different endplates. The type of pilot air supply is determined by the sealof the soft-start valve.

The soft-start valve is actuated electrically independently bythe multi-pin/fieldbus connection via a 4-pin plug (in accord-ance with ISO 15407-1) or separately via an optional M12adapter.

Switch-on takes place in two stages:

– First the working pressure provided for duct (1) graduallyincreases. The speed can be adjusted using a flow controlscrew.

– Once the working pressure in duct (1) reaches a previ-ously set value, the soft-start valve switches the full oper-ating pressure at duct (1) of the valve terminal.

When the valve terminal is supplied with internal pilot air viathe soft-start valve, the full operating pressure is alwayspresent at duct (14). This pressure causes the valves on thevalve terminal to immediately move to the required switching



position. When the valve is not switched, duct (1) of the valveterminal is exhausted via the soft-start valve's exhaust port.

The switching point for full operating pressure is set to 4 barat the factory, but can be changed using an adjusting screw.

The piston position of the soft-start valve can optionally bemonitored by an inductive sensor (N/O contact). This sensorregisters whether the valve has switched and thereforewhether the valve terminal is being supplied with air. Due tothe required calibration, the later addition of the sensor bythe customer is not intended. A pressure gauge is optionallyavailable as a pressure indicator.

Note– The VTSA/VTSA-F valve terminal can be equipped with amaximum of 5 soft-start valves.

– If a soft-start valve is used in the VTSA/VTSA-F valveterminal, no additional pressure-supplying componentsmay be used in the same pressure zone.

– Exhaust air cannot be expelled via the soft-start valve. Ifa pressure zone is operated with a separate duct (1) and3/5, an exhaust plate is required in this pressure zone.

– Instructions for combining the soft-start valve, pneumat-ic supply plate and the right end plate can be found inthe assembly instructions for VABV-S6-1Q-....

NoteWhen using “Protection against unexpected start-up”:protection against unintentional operation of the MO is tobe ensured for all operating modes.



Control block

The VOFA-B26-T52-M-... control block (Ident. Code SP or SN)is intended for two-channel control of pneumatic drive com-ponents (e.g. double-acting linear cylinders) and can be usedfor implementing the following safety functions:

– protection against manipulation, prevention of unexpec-ted start-up (EN 1037)

– safe reversal of a hazardous movement, provided thereversing motion itself will not result in further hazards.

1.2.9 Vacuum block VABF-S4-1-V2B1

The VABF-S4-1-V2B10 vacuum block is used to generate avacuum. The generated vacuum and a suction gripper pro-duce a force which is used to grip and transport a workpiece.The supply of compressed air for vacuum generation is con-trolled by an integrated solenoid valve. The vacuum is gener-ated by actuating solenoid coil 12. The set reference value forthe generated vacuum is monitored via an integrated pres-sure sensor. Vacuum generation reverts to a self-holdingphase after reaching the set reference value. The vacuumblock controls the vacuum generation process independentlywithin the range of the set switching points (air-saving func-tion). With the integrated solenoid valve, an ejector pulse isactivated and generated by activating coil 14 to release theworkpiece safely from the suction cup and to reduce the va-cuum quickly. The length of the ejector pulse can be influ-enced by the duration of the electrical pulse. The strength ofthe ejector pulse is influenced by the adjustable flow controlvalve.

1.3.1 Valves

The following valve functions are available for theVTSA/VTSA-F valve terminal in width 65 mm:

– 5/2-way valves, (monostable or bistable)

– 5/3-way mid-position valves.

Valves of width 65 mm (ISO 3) can be operated on the theVTSA/VTSA-F valve terminal as follows:

– standard operation

– reversible operation

– low pressure

– vacuum.

Identifying the valves Valves of width 65 mm are identified by type code. The typecode is printed on the rear of the valve. An identifier withinthe type code indicates the function of the valve. For ex-ample, identifier 5/2-...-FR in the type code VL-5/2-D-3-FR-Cmeans that the valve is a monostable 5/2-way valve withmechanical spring. You can identify the valve function withthe aid of the following table. In the sales documentationand in the Festo Configurator the valves are marked with anIdent. Code.

1.3.2 Manifold sub-bases

The number of electrically controllable valve positions de-pends on the manifold sub-bases and the electrical connec-tion used (� Tab. 1/2).

If only manifold sub-bases that support the control of twosolenoid coils per valve position are used, any type of valvecan be placed in any valve position.

If, on the other hand, only manifold sub-bases that controlonly one solenoid coil per valve position are used, the valveterminal can only be equipped with monostable 5/2-wayvalves (Ident. Code M or O) or cover plates.

1.3.3 Pressure zones

The VTSA valve terminal of width 65 mm can be operated witha maximum of 2 pressure zones. These pressure zones areformed by isolating discs. These are inserted between themanifold blocks in the supply duct (1) and, for special cases,in the air exhaust ducts (3 or 5) as well. The first pressurezone is supplied with compressed air via the adapter plate,while the second pressure zone is supplied via the right endplate.

1.3.4 Vertical stacking

You can mount further components at each valve positionbetween the manifold sub-base and the valve. These verticalstackings enable you to implement certain additional func-tions as desired.

3. Installation


3.1 Compressed air preparation

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

• Operate the VTSA/VTSA-F valve terminal as described inthe following two sections.

3.1.1 Operation with unlubricated compressed air

NoteToo much residual oil content in the compressed air willreduce the service life of the valve terminal.

– When using bio-oils (oils that are based on syntheticester or native ester, e.g. rapeseed oil methyl ester), themaximum residual oil content of 0.1 mg/m3 should notbe exceeded (� ISO 8573-1 class 2).

– When using mineral oils (e.g. HLP oils to DIN 51524 Part1 to 3) or corresponding oils based on polyalphaolefin(PAO), the maximum residual oil content of 5 mg/m3

must not be exceeded (� ISO 8573-1 class 4).

This avoids operative malfunctions of the valves.

Excessive residual oil content is not permissible, independentof the compressor oil, as otherwise the basic lubrication willbe washed out with time.

3. Installation


3.1.2 Operation with lubricated compressed air

Operate system equipment with unlubricated compressed air,if possible. In this way, you protect 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.

NoteThe lifetime lubrication required for unlubricated operationcan be “flushed out” when products are operated usinglubricated compressed air.

If the system was commissioned with lubricated com-pressed air, a changeover to provisioning with unlubric-ated compressed air is not possible.

Note the following instructions if lubricated compressed airmust be used.

NoteThe quality of compressed air downstream of the com-pressor must correspond to that of unlubricated com-pressed air.

• If possible, do not operate all of your equipment withlubricated compressed air.

• If possible, always install the lubricators directly up-stream of the consuming actuator.

3. Installation


NoteIncorrect supplemental oil and an oil rate in the com-pressed air that is too high will reduce the service life ofthe valve terminal.

• Use Festo special oil OFSW-32 or the alternatives listedin the Festo catalogue (as per DIN 51524-HLP32, basicviscosity 32 CST at 40 °C).

• HLP 32 oils are to be used (according to ISO 8573-1,5.3.2 or 5.3.5).

• The additional lubrication must not exceed 25 mg/m³(ISO 8573-1 class 5).

• Check the correct lubricator setting (� following sec-tion).

This avoids operative malfunctions of the valves.

Setting the lubricator With the machine running (typical operating status):

– 0.2 to max. 1 drop/min.

or

– 0.5 to 5 drops/1000 l air.

Checking the setting The procedure described below can be used to check thelubricator setting.

NoteCheck the service units for condensate and lubricator set-ting twice per week.

1. Ascertain the actuator which is furthest from the lubricat-or.

2. Ascertain the valve terminal which controls this actuator.

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

3. Installation


4. Hold a piece of white cardboard at a distance of 10 cmfrom the exhaust port.

5. Let the system run for some time.

6. Check the discolouration of the cardboard:

– There must be only a slight yellow colouring on thecardboard.

– If oil droplets appear, this is an indication that toomuch oil has been used.

Another indicator of over-lubrication is the coloration orstatus of the exhaust air silencer:

– a distinctly yellow colouring of the filter element

– droplets of oil on the silencer indicate that the lubricatorsetting is too high.

7. Correct any incorrect lubricator settings. If applicable,take comprehensive maintenance measures of the com-pressed air supply into consideration.

3. Installation


3.2 General notes on connecting the tubing

WarningUncontrolled movement of the actuators, undefinedswitching states and loose tubing lines.

This may result in personal injury or damage to property.

• Switch off the operating and load voltage supplies


• Exhaust the valve terminal pneumatics.

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

– Rules for complying with the UL certification can befound in the separate UL-specific special documentation.The relevant technical data listed there also apply here.

– The technical data in this documentation may show val-ues deviating from this.

Please note the following:The components of the valve terminals contain electrostatic-ally sensitive components. The components could be dam-aged if you touch the contact surfaces of the plug connectorsor if you do not observe the handling specifications for elec-trostatically sensitive devices.

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-directional control valves that are normallyclosed.

3. Installation


To avoid back pressures:

• Optimise the pressurisation and ventilation capacity ofthe valve terminal, for example, by using larger diametertubing or an additional compressed air supply via pneu-matic supply plates with venting via a silencer or exhaustplate.

• Separate the exhaust ducts, if necessary, by using pres-sure zones (� Section 1.2.5).

3.2.1 Installing the tubing

If angled connectors or multiple distributors are used, the airflow will usually be reduced.

Connection Proceed as follows:

1. Push the tubing as far as possible into or over the tubecoupling of the fitting.

2. Depending on connection:

– If necessary, pull the locking ring1 over the tubecoupling (� Fig. 3/1).

– Tighten the clamping screw2 (� Fig. 3/1).

– For the right end plate, size 2:First mount the tubing at port (1) and then at ports (3)and (5).Secure the tubing with a hose clamp3.

3. For better system clarity, bundle together the installedtubes with:

– tubing straps or

– multiple hose holders.

WarningUncontrolled movement of loose tubing lines.

This may result in personal injury.


• Vent the pneumatics

• Vent actuators that are controlled by valves

1. Mark all pneumatic tubing.

2. Depending on connection:

– Loosen the clamping screw1 of the threaded con-nector.

– Press down the locking ring of the threaded connect-or2, e.g. with a Festo QSO releasing tool.

– Loosen the hose clamp screw3.

3. Remove the tubing from the fitting.

4. Seal non-required fittings with blanking plugs4.

3.3 Connecting the VTSA/VTSA-F valve terminal

To protect the working ports (2 and 4) from contamination,seal unused valve positions (valve positions that are fittedwith cover plates) with blanking plugs or threaded blankingplugs.

NoteIn order to guarantee the optimum efficiency of the valveterminal, we recommend in the following cases that morethan one supply or exhaust line be used:

– When large volume cylinders are operated at highspeeds

– When many valves are pressurised or exhausted simul-taneously.

To do this, equip the VTSA/VTSA-F valve terminal with asufficient number of pneumatic air supply plates.

3.4 Pilot control, width 18 ... 52 mm

3.4.1 Venting pilot exhaust air

As per standard ISO 15407-2 and 5599-2, ports (12) and (14)are intended for supplying the valve terminal with externalpilot air.

The Festo valves for the VTSA/VTSA-F valve terminal require apilot air supply exclusively via duct (14). In the case of thereversible 2x3/2-way valves from Festo, additional operatingpressure is also required at duct (12) for the pneumaticspring. This operating pressure must correspond to the pilotpressure.

All other valves from Festo which are operated so they complywith the ISO standard work independently of duct (12). Thepilot exhaust air is vented directly at each valve in an unduc-ted manner.

3. Installation


The pilot exhaust air can also be vented via duct (12)(� Section 5.6.1). There should not be any pressure in theduct (12) in this case, as this would prevent the valves fromswitching.

Therefore, please observe the following points if you wish touse duct (12) for venting the pilot exhaust air:

– The valve terminal is not equipped with reversible 2x2/2-or 2x3/2-way valves.

– The valve terminal is not equipped with valves from othermanufacturers.

– The seals between the manifold sub-bases and the valvesmust be mounted in the corresponding position(� Section 5.6.1).

– Valve terminals with a selector end plate must be oper-ated in positions 3 or 4 of the selector plate (� Tab. 3/3).

3. Installation


3.4.2 Pilot air supply

Note• The VTSA/VTSA-F valve terminal can either be suppliedwith internal pilot air via the VABF-S6-1-P5A4-... soft-start valve or with internal or external pilot air via thecorresponding right end plate.

• The port seal used for the soft-start valve determineswhether the internal pilot air is supplied via the soft-startvalve or the right end plate (� Assembly instructionsVABV-S6-1Q-...). If the supply of internal pilot air via thesoft-start valve is selected, there must be no other pilotair supply feed (duct (14)) within the valve terminal.Exhaust air cannot be expelled via the soft-start valve.An exhaust plate is required for operation in a pressurezone with separated ducts (1) and (3/5).

Internal pilot air supply If the operating pressure lies within the required pilot pres-sure range for the valves (� Appendix A, Tab. A/5 andFig. A/1), you can operate the pilot control with an internallybranched pilot air supply. The pilot air is branched here fromsupply duct (1).

NoteThe internal pilot air supply is also branched centrally fromsupply port (1) if the VTSA/VTSA-F valve terminal isequipped with several pressure zones.

External pilot air supply If the operating pressure lies outside the required pilot pres-sure range for the valves (� Appendix A, Tab. A/5 andFig. A/1), the pilot control must be supplied with externalpilot air. The pilot air is to be supplied via pilot port (14).

3. Installation


Note• External pilot air is supplied centrally via pilot port (14)on the right end plate. This is the case even if the valveterminal is operated with different pressure zones(� Fig. 3/5).

• Set the pilot pressure according to the specifications inAppendix A, Tab. A/5 or in the diagrams Fig. A/1.

• Check which pilot variant your valve terminal has beendesigned for (� Section 1.2.4 “Pilot control (pilot air sup-ply)”).

• Carry out the necessary installation procedures or set-tings in accordance with Tab. 3/1 and Tab. 3/2.

NoteValve terminal with selector end plate:

Danger of damage to the selector plate.

To change the selector plate position, first remove the lock-ing screw then pull the selector plate out of the guide inthe end plate before inserting the selector plate into thenew position.

Valve position with vertical pressure shut-off plate:

• In this valve position, duct (14) is blocked by the verticalpressure shut-off plate (� Appendix B, Tab. B/10). Thevalve is supplied with pilot air internally branched fromduct (1). This is the case even if the valve terminal isoperated with external pilot air supply.

Valve terminal with selector end plate and vertical pres-sure shut-off plate:

• The valve terminal may only be operated in positions 3and 4 of the selector plate. Otherwise, pilot air 12 mayescape at the interface to the valve when the valve isreplaced and the pilot pressure could break down.

3.5 Pilot control, width 65 mm

3.5.1 Pilot air supply

Caution• Only operate the valve terminal with compressed air orinert gases (e.g. nitrogen).

• Valve terminals with externally supplied pilot air:Use the aforementioned media for the pilot air (ports 12or 14) without lubrication where possible. Otherwiseobserve the instructions in the section “Compressed airpreparation”.

• Valve terminals with internally branched pilot air:Use the aforementioned media for the supply air (port 1)without lubrication where possible. Otherwise observethe instructions in the section “Compressed air prepara-tion”.

Pilot control of the solenoid coils can be operated with intern-al or external pilot air, depending on the intermediate solen-oid plate.

Internal pilot air supply If the operating pressure of the valve terminal lies between3 ... 10 bar, pilot control can be operated with internallybranched pilot air. The pilot air is branched here from supplyduct P1.

3. Installation


If the valve terminal is prepared for internal pilot air,

– a plug pin is located in each of the pilot control ducts 12and 14 on the underside of the intermediate solenoidplate (� Fig. 3/3).

Fig. 3/3: Intermediate solenoid plate, positions of the plugpins in air ducts 12 and 14

External pilot air supply If the operating pressure lies below 3 bar, the pilot control ofthe solenoid coils must be operated with external pilot air.

Note• Use regulated external pilot air (3 ... 10 bar). Reliablefaultless operation of the valve terminal is then possible,e.g. even with fluctuating operating pressure.

• The external pilot air is supplied via pilot port 12 or 14on the right end plate.

If the valve terminal is prepared for external pilot air,

– a plug pin is located in duct 1 on the underside of eachintermediate solenoid plate (� Fig. 3/4); the flow from 1to the pilot control ducts is therefore blocked

3. Installation


3.6 Pressure zone separation, width 18 ... 52 mm

The pressure zones are separated from each other throughspecial seal plates (� Section 1.2.5). Each pressure zonemust be supplied with compressed air via a pneumatic sup-ply plate or the right end plate with side ports (� Fig. 3/5).

Note• If the VTSA/VTSA-F valve terminal is also equipped withother valves, operate valves with Ident. Code VV (revers-ible 2x2/2-way valves) in a separate pressure zone withseparate exhaust ducts (3) and (5).

Note the following in the case of VTSA/VTSA-F valve ter-minals which are operated with an internal pilot air supplyand which have several pressure zones:

• The pilot air is branched centrally for all solenoid coilsfrom supply port (1) in the right end plate (� Fig. 3/5)or the soft-start valve.

• The pressure zone which is supplied via supply port (1)of the right end plate must be operated with a pressurethat corresponds to the required pilot pressure for thevalve terminal at the very least (� Appendix A, Tab. A/5,Fig. A/1).

3. Installation


The following figure shows the assignment of the supply andexhaust ports to the valves using an example of a VTSA/VTSA-F valve terminal with blocked ducts (1), (3) and (5).

The ports (1) or (3) and (5) are:

– For the pressure zone on the outside right:

– In the right end plate if the valve terminal is equippedwith end plate VABE-...R-... or VABE-...RZ-....

– In the pneumatic supply plate of the outside rightpressure zones if the valve terminal is equipped withend plate VABE-...RZ-...B1.

– For each additional pressure zone:In the pneumatic supply plate which is located within thecorresponding pressure zone.The supply plate can be positioned anywhere within thepressure zone (left, centre or right).

Ports (12) or (14) on the right end plate are for valve termin-als with pilot control by means of external pilot air supply.

By mounting an additional supply plate within a pressurezone you can provide additional supply air or extract exhaustair.

3.8 Reversibly operated VTSA/VTSA-F valve terminal

For reversible operation of the VTSA/VTSA-F valve terminal,the operating pressure is supplied via ports (3) and (5) andthe exhaust is vented via port (1).

Operate a reversible VTSA/VTSA-F valve terminal only with anexternal pilot air supply.

In the case of valve terminals with a selector end plate, theselector plate must be set as follows:

– position 1 for ISO-compliant operation of the valve terminal

– setting 3 for operation of the valve terminal with pressure-less duct (12) (venting of pilot exhaust air via port (12)).

Note• If the valve terminal is equipped with reversible 3/2-wayvalves (Ident. Code P, Q and R), you operate the valveterminal exclusively in position 1 of the selector plate.

3. Installation


3.8.1 Operating the VTSA/VTSA-F valve terminal with reversible valves

Note– If reversible valves are operated on the valve terminaltogether with standard valves, the reversible valves areto be operated in a separate pressure zone.

– Exception:The combination of reversible 2x3/2-way valves (Ident.Code P, Q and R) on reversible pressure regulators (iden-tifier R5) must not be operated in a separate pressurezone. The reversible pressure regulators supply pres-sure via duct (1) and vent the exhaust air via ducts (3)and (5).

– The reversible 2/2-way valve with Ident. Code VC shouldnot be operated on reversible pressure regulators (iden-tifier R5). The reversible 2/2-way valve requires excesspressure in duct (1) for the pneumatic springs. The excesspressure should correspond to the pilot pressure.

You can operate the valve terminal VTSA/VTSA-F with revers-ible 2x3/2-way valves (Ident. Code P, Q and R) if the followingrequirements are met.

– Duct (12) is not available for venting the pilot exhaust air,as the reversible 2x3/2-way valves require compressedair from duct (12) for the pneumatic spring. Valves thatare configured for venting the pilot exhaust via port (12)can then no longer be switched (� Section 5.6.1).

– Valve terminal with right end plate VABE-...RZ-...B1:If the pressure zone next to the right end plate is suppliedwith operating pressure via port (1), the valve terminalmust be operated in position 1 or 2 of the selector plate(� Tab. 3/3). If this pressure zone is operated in a revers-ible manner, however, the valve terminal should only beoperated in position 1 of the selector plate (� Tab. 3/3).

3. Installation


– Right end plate VABE-...R-...:Port (14) is supplied sealed with a blanking plug. Thepilot air supply is branched internally from duct (1).In order to guarantee the resetting of the reversible2x3/2-way valves via the pneumatic spring, port (12)must be supplied with operating pressure (valve circuitdiagrams� Appendix B Tab. B/4).

– Right end plate VABE-...RZ-...:The external pilot air supply is to be supplied with thesame pressure level via ports (12) and (14).

3.8.2 Operating the VTSA/VTSA-F valve terminal with reversible pressureregulators

NoteOperating the VTSA/VTSA-F valve terminal with reversiblepressure regulators (identifier R5-..., R6-..., R7-...):

– Reversible pressure regulators must not be used on re-versibly operated valve terminals.

– These pressure regulators cannot be used to operate any2x3/2-way valves with Ident. Code K, H and N (non-revers-ible valves) or any 2/2-way valves with Ident. Code VC andVV. These valves require excess pressure in duct (1) forthe pneumatic springs.

– The combination of reversible 2x3/2-way valves (Ident.Code P, Q and R) on reversible pressure regulators (iden-tifier R5) must not be operated in a separate pressurezone. The reversible pressure regulators supply pres-sure via duct (1) and vent the exhaust air via ducts (3)and (5).

3. Installation


3.8.3 Setting the pressure regulator

The pressure regulator plates can be set using the followingoperator control elements:

– for widths 18 ... 52 mm with the rotary knob

– alternatively, with widths 18 mm and 26 mm with the ad-justing screw in the rotary knob.

NoteWhen using A, B and AB pressure regulators VABF-S4...and VABF-S2... (identifier in type code: R2, R3, R4) thecontrol pressure should not be below 2 bar. Use the re-versible A, B, or AB pressure regulator (identifier in typecode: R6, R7, R5) for control pressures below 2 bar� Tab. 1/12.

Setting the pressure regulator, width 52 mm:If the rotary knob cannot be used for setting the pressureregulator because it is encapsulated by the adjacent rotaryknobs, the rotary knobs of the adjacent pressure regulatorcan be removed temporarily. This results in sufficient space tooperate the rotary knob.

3. Installation


Setting the pressure regulator with lock

Proceed as follows:

1. Turn the key 90° in a clockwise direction. The rotary knobis pushed upward through spring force. The rotary knobis in the regulating position.

2. Turn the rotary knob completely closed in the “–” direc-tion.

3. Slowly pressurise the VTSA valve terminal.

4. Turn the rotary knob in the “+” direction until the desiredpressure is displayed on the pressure gauge. The permit-ted working pressure (� rating plate) must not be ex-ceeded. Correctly pressurised, the supply pressure p1 isat least 0.5 bar higher than the output pressure p2.

5. Press the rotary knob downward against spring force untilthe end position.

6. Turn the key 90°in an anti-clockwise direction. The pintailof the lock runs out and locks the rotary knob. The regu-lator cannot be adjusted.

3.9 Vacuum / low-pressure operation:

NoteIf valves are used for switching a vacuum, filters must beused in the suction line to avoid operative malfunctionscaused by foreign matter sucked into the line.

Valves with Ident. Code K, H, and N (2x3/2-way valves) withsupply via port (1) are not suitable for vacuum or low pres-sure.

– Operate these valves in a separate pressure zone.

– The operating pressure for this pressure zone must beset in accordance with the diagram in Appendix A,Fig. A/1.

The following conditions must be fulfilled before you can op-erate the VTSA/VTSA-F valve terminal at supply port (1) withvacuum or low pressure between –0.9 ... 3 bar:

– the pilot control is operated with an external pilot air sup-ply

– the valve terminal is fitted with the following valve sub-bases and sometimes has additional pressure zones:

3. Installation


Valve sub-bases

Pressure zone with vacuum orlow pressure supply via connec-tion (1)

The pressure zone must be equipped only with the following valvesub-bases:– 5/2-way valve, monostable (Ident. Code M and O)– 5/2-way double pilot valve (Ident. Code J and D)– 5/3-way valves (Ident. Code G, E and B)– reversible 3/2-way valves (Ident. Code P, Q and R). These valves

must be operated via port (3) and (5) in a separate pressurezone with vacuum or low pressure.

Valves with Ident. Code K, H, and N (2x3/2-way valves) with supplyvia port (1) are not suitable for vacuum or low pressure.

Pressure zone with excess pres-sure supply 1) via port (1)

The pressure zone can be fitted additionally with the followingvalve sub-bases:

- 2 x 2/2-way valves (Ident. Code VC and VV),� followinginstructions

– 2x3/2-way valves (Ident. Code K, H and N).

1) in accordance with diagrams in Appendix A, Fig. A/1

Tab. 3/4: Valve sub-bases

NoteReversible 2x2/2-way valves with Ident. Code VV:

– If the VTSA/VTSA-F valve terminal is also equipped withother valves, operate the reversible 2/2-way valve in aseparate pressure zone with separate exhaust ducts.Connecting the valve in vacuum operation:

– Supply operating pressure for the pneumatic springs atport (1).

– Either supply vacuum at port (5) and operating pressureat port (3) or vice versa.

– The suction line (line supplied with vacuum) shall beequipped with a filter to prevent any contamination fromentering into the valve.

– To enable the ejector pulse during vacuum operation aconnection is to be established between the suction lineand the pressure line via a T-piece.

3. Installation


3.10 Connecting the pneumatic lines

CautionThe identification of the working ports on the 90°-connec-tion plate refers to the position of the 90°-connection platepre-assembled by Festo (� Fig. 3/10).

It is possible to mount the 90°-connection plate with theexit for the working ports in the direction of the valve baselevel, but this is not supported by Festo because the desig-nation of the ports no longer applies in this direction ofmounting.

3. Installation


Note• Use blanking plugs to seal all ports not required for thefunctioning of the valve terminal.

• If the VTSA/VTSA-F valve terminal is to be operated inconformity with the ISO standard, the pilot exhaust airwill be vented directly at the valve in an unducted man-ner.

Width 18 … 52 mm:

• For external pilot air supply you only have to supply thepilot air at port (14).

• If the pilot air is to be vented ducted via port (12), thevalve terminal can, under certain circumstances, nolonger be operated with ISO valves from other manufac-turers. Observe the instructions from the valve manufac-turer in this case. Conversion of the valve terminal toducted pilot exhaust is described in section 5.6.1.

Width 65 mm:

• For external pilot air supply you only have to supply thepilot air at port (12) and (14).

• The supply ports are in the adapter plate and in the rightend plate. Connect the compressed air lines (operatingpressure) and exhaust air lines to the adapter plate andthe right end plate. Make sure the valves are sufficientlypressurised and exhausted.

• For operation with two pressure zones, each side mustbe supplied separately with operating pressure.

NoteFor the combination of widths 18 ... 52 mm with width65 mm:

• For external pilot air supply connect the pilot air asfollows:

– for widths up to 52 mm in the adapter plate

– for width 65 mm in the right end plate.

3. Installation


CautionIf the VTSA/VTSA-F valve terminal is also equipped withthe reversible valves (Ident. Code VV, P, Q and R), whenconnecting the valve terminal, please observe the instruc-tions in the sections 3.6/3.8.1/3.9 and in Appendix B1Tab. B/4 and Tab. B/5.

NoteValve terminal with soft-start valve:

– If a soft-start valve is used in the VTSA valve terminal, noadditional pressure-supplying components may be usedin the same pressure zone.

– Exhaust air cannot be expelled via the soft-start valve. Ifa pressure zone is operated with a separate duct (1) and3/5 duct, an exhaust plate is required in this pressurezone.

• Dependent on the position of the soft-start valve on thevalve terminal, the pressure zones and the pilot air sup-ply variants, the ports on the right end plate or pneumat-ic supply plate are to be sealed with blanking plugs.Important information about this can be found in theassembly instructions VABV-S6-1Q-...

First mount the seals and then the fittings and/or silencer(position of the ports� Fig. 3/10, Fig. 3/11 and Fig. 3/12.Port size� following tables). Then lay the tubing lines.

3.11 Connecting the electric cables

WarningVTSA/VTSA-F valve terminals with 24 V DC control voltage:

• Only use PELV circuits in accordance withIEC/EN 60204-1 (protective extra-low voltage, PELV) forthe electrical power supply.

• Observe the general requirements of IEC/EN 60204-1 forPELV circuits.

• Use only voltage sources that guarantee a reliable elec-tric separation of the operating and load voltage in ac-cordance with IEC/EN 60204-1.

VTSA/VTSA-F valve terminals with 110 V AC controlvoltage:

• Observe the applicable safety regulations for workingwith 110 V AC control voltage.

• Make sure that the earth terminal of the valve terminal isconnected to the protective earth.

The use of PELV circuits ensures protection from electricshock (protection from direct and indirect contact) in accord-ance with IEC/EN 60204-1 (Electrical equipment of machines,General requirements).

Note• Ascertain which measures, in line with your EMERGENCYOFF procedures, are necessary for putting your ma-chine/system into a safe state in the event of an EMER-GENCY OFF (e.g. switching off the operating voltage forthe valves and output modules, switching off or pres-sure).

3. Installation


CautionLong signal lines reduce the resistance to interference.

• Do not exceed the maximum permitted signal cablelength of 30 m.

NoteFor valves with Ident. Code SO, SQ, SP and SN (valves withswitching position sensing via sensor), Festo recommendsusing lines with straight plugs.

Contents of this chapter This chapter describes the commissioning procedure for theVTSA/VTSA-F valve terminal. This includes in particular thefollowing:

– instructions on building up pressure in the overall supply

– operation of the manual override tools

– checking the valves and the valve-actuator combination

– the assignment of LEDs and manual overrides to thesolenoid coils

– function impairments

– operating states of the pneumatic system.

Further information The commissioning procedure for the CPX terminal is de-scribed in the corresponding manual for the CPX bus node.

4. Commissioning


4.1 General instructions

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:

– maximum number of valves

– maximum operating voltage

– when the solenoid coils are constantly under stress.

• Please observe the subsequent instructions on pressurebuild-up in the overall supply.

4.1.2 Pressure build-up in the overall supply

WarningSudden movement of the actuator caused by slow ordelayed pressure build-up of the pilot air

Personal injury and damage to the machine/system

• Operate the valve terminal with external pilot air corres-ponding to the pressure specified in Appendix A,Tab. A/5. The pilot air is to be branched in front of thesoft-start valve for gradual pressure build-up(� Fig. 4/1).

• Pay attention to any electric signals present (e.g. afterEMERGENCY STOP).

• Exercise care and attention when switching on the com-pressed air via the soft-start valve for gradual pressurebuild-up.

4. Commissioning


The pilot air must be applied immediately after it is switchedon at the minimum pressure specified in Appendix A, Tab. A/5for the relevant valves. Otherwise there is no guarantee thatthe valve will switch directly (� Fig. 4/1).If the pressure is below this minimum pressure, it may, des-pite an applied electrical signal, result in a delayed switchingof the valve. The gradual pressure build-up of the overall sup-ply does not affect the actuator in that case. The actuatorwould react suddenly (e.g. a cylinder would extend or retractsuddenly, depending on the valve function).

4.2 Manual override (MO)

The manual override should be used especially when com-missioning the pneumatic system to check the functionalityand operation of the valve and/or valve-actuator combina-tion.

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

4. Commissioning


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

Actuation type Mode of operation

Width 18 ... 52 mm Width 65 mm

Non-detenting After actuation, the manual override is reset automatically by aspring.

Turning with detent The manual override remainsactuated until it is reset byhand.

4.2.1 Manual override, width 18 ... 52mm

NoteIf the VTSA/VTSA-F valve terminal is used in a dusty envir-onment, Festo recommends that you protect the manualoverrides with cover caps VAMC-S6-CS against dirt anddust when the valve terminal has been commissioned. Atthe same time the manual overrides are protected againstincorrect use.

The detenting/non-detenting function of the manual overridecan be changed to just a non-detenting function by mountinga cap.

5.4 Replacing the solenoid coil fuse, width 65 mm

Each solenoid coil is protected with a (fast-blowing) 0.315 Afuse. The fuses can be found on the circuit boards behind thecovers of the manifold sub-bases.

The manifold sub-base VIGM-04-D-3 (manifold sub-basewhich supports the actuation of one solenoid coil) has a fuse.The manifold sub-base VIGI-04-D-3 (manifold sub-base whichsupports the actuation of two solenoid coils) has two fuses(� Fig. 5/1).

In order to replace the fuses proceed as follows (see followingdiagram):

1. Switch off the compressed air supply and the voltage sup-ply.

2. Open the cover of the corresponding manifold sub-base.

3. Carefully remove the fuse from its base (� Fig. 5/1).

– right: fuse for solenoid coil 14

– left: fuse for solenoid coil 12.

4. Insert the new fuse.

5. Close the cover.

5.5 Replacing valve terminal components

Components on the manifold sub-bases of the VTSA/VTSA-Fvalve terminal can easily be replaced for maintenance andconversion work.

5.5.1 Replacing valves or cover plates, width 18 ... 52 mm

NoteDepending on the manifold sub-base, the VTSA/VTSA-Fvalve terminal supports the control of one or two solenoidcoils per valve position.

– Manifold sub-base VABV-...-T1 supports the actuation ofa solenoid coil for each valve position and is designatedby a red solenoid coil contact housing. There is a blackdot on the rating plate of the manifold sub-base.

– Manifold sub-base VABV-...-T2 supports the actuation oftwo solenoid coils for each valve position and is desig-nated by a black solenoid coil contact housing.

Dismounting Proceed as follows:

• Use a screwdriver with a narrow blade to loosen themounting screws and remove the component from themanifold sub-base (� Fig. 5/2).



Fig. 5/2: Removing valves or cover plates


1. Check the seals for damage. Replace seals if they aredamaged.

2. Make sure that the seals are seated correctly.The cord seal between the manifold sub-base and com-ponent must be seated in the recess of the component.

3. Place the component on the manifold sub-base.

4. Screw the component at first only slightly and then tight-en with the following torque:

– valve width 18 mm (VSVA-...-A2): 1.0 Nm (± 10 %)

– valve width 26 mm (VSVA-...-A1): 2.0 Nm (± 10 %)

– valve width 42 mm (VSVA-...-D1): 3.0 Nm (± 20 %)

– valve width 52 mm (VSVA-...-D2): 6.5 Nm (± 20 %)



5.5.2 Replacing the cover plate with a valve, width 65 mm

NoteDepending on whether you are using a single-solenoidvalve with spring reset, a single-solenoid valve with pneu-matic spring or a double-solenoid valve, you will requirethe appropriate intermediate solenoid plate.

Non-assigned valve locations are sealed with cover plates.This will guarantee the following:

– Cavities of the manifold sub-base are protected againstcontamination.

– Pressure-tight sealing of the valve or coil connection level.

Dismantling • Loosen the screws from the cover plate at the valve pos-ition and remove the cover plate from the manifold sub-base.

Mounting 1. Insert new seals.

2. Screw the 4 supplied stud bolts into the mounting holesof the manifold sub-base.

3. Place the intermediate solenoid plate on the manifoldsub-base.

4. If applicable, place additional components on the inter-mediate solenoid plate and screw these componentstight.

5. Fasten the valve.

5.5.3 Replacing/adding components for vertical stacking, width18 ... 52 mm

The valve terminal can be equipped with the following com-ponents for vertical stacking:

– pressure regulator plate

– flow control plate

– pressure shut-off plate

– vertical pressure supply plate.

NoteLoss of function in the following cases!

Do not combine standard 2x3/2-way valves (Ident. Code K,H, N) with reversible pressure regulator plates (identifierR5-..., R6-..., R7-...). With this combination, the pneumaticspring of the valves does not function. The valves cannotreturn from the switching position to the neutral position.

Vertical stacking with pressure regulator plate:When combining the pressure regulator plate with the flowcontrol plate, vertical pressure shut-off plate or vertical pres-sure supply plate, mount the aforementioned componentsunder the pressure regulator plate. Doing this will ensure freeaccess to the adjusting screws and connections (� Tab. 5/3).

When placing a repeat order for pressure regulators in 42 mmand 52 mm widths, please note the following:The printed part number on the regulator plate only refers tothe standard configuration. When reordering pressure regu-lators with additional features, such as a lockable rotaryknob, extended design etc., only use the VABF configurator.



The following component sequence is recommended for valvepositions with vertical stacking:

Fig. 5/4: Assembly sequence for vertical stacking



Note– Valve position with vertical pressure shut-off plate:vertical pressure shut-off plates are only intended incombination with VSVA valves from Festo. In the verticalpressure shut-off plate only duct 1 and 14 are blocked(not duct 12).

The pilot air supply for the valve is branched internallyfrom duct (1) in the vertical pressure shut-off plate, evenif the valve terminal is operated with external pilot airsupply (� Appendix B, Tab. B/10).

If all the valve positions on the VTSA/VTSA-F valve ter-minal are equipped with vertical pressure shut-offplates, it will not be necessary to supply the valve ter-minal with external pilot air. The operating pressure withwhich the valve terminal is operated must be within therange of required pilot pressure in this case (� Ap-pendix A, Tab. A/5 and Fig. A/1).

– Reversible pressure regulator plates should only becombined with valves that can be operated in a revers-ible manner.

– Combining reversible valve terminals with the followingvertical stacking components is not permitted:

– reversible pressure regulator plates

– flow control plates

– vertical pressure shut-off plates

– vertical pressure supply plates.



Proceed as follows:

Dismantling 1. Unscrew the screws of all components above the re-spective position.

2. Remove these components from the valve position.

Mounting 1. Check the seals for damage. Replace any damagedseals.

2. Place the new component at the valve position, or, ifapplicable, onto a component already fitted.

5.6.2 Conversion, internal or external pilot air supply,width 18 ... 52 mm

The pilot control can be operated with an internal or externalpilot air supply depending on the right end plate (� Tab. 3/2and Tab. 3/3).

NoteMixed operation of the VTSA/VTSA-F valve terminal with aninternal and external pilot air supply is not intended. Irre-spective of the available pressure zones, all solenoid coilsof the valve terminal are supplied centrally with the samepilot air supply.

Selector end plate VABE...RZ-...B1

When using a VTSA/VTSA-F valve terminal with selector endplate VABE-...RZ-...B1 you can alter the type of pilot air supply(internal or external) by the position of the pilot air selector(� Tab. 3/3).In addition, you can also specify whether the pilot exhaust airshould be vented via port (12) (deviating from the ISO stand-ard).

End plates with axial supply ports VABE...R-...or VABE-...RZ-...

The procedure for replacing the end plates is described insection 5.5.6.



5.6.3 Conversion, internal or external pilot air supply, widths 65 mm

WarningSwitch off the following before undertaking conversionwork:

– compressed air supply

– the operating voltage supply for the electronics (pin 1)

– the load voltage supply for the outputs/valves (pin 2).

The valve terminal is configured for internal pilot air.

You can alter the pilot control of the solenoid coils to internalor external pilot air by opening or closing the correspondingducts in the intermediate solenoid plates.

NoteThe 5/2-way valve with pneumatic spring (type VL-5/2...) isnot intended for operation with external pilot air. In thisvalve, the pneumatic spring is supplied by duct (1).

Procedure:

• Change the position of the plug pin on the underside ofthe intermediate solenoid plate (� Fig. 3/5).

• For external pilot air supply:Feed the pilot air supply via port 12 or 14 on the right endplate.

• For internal pilot air supply:Seal the ports 12 and 14 on the right end plate withblanking plugs (these need to be ordered separately).



Changing the position of the plug pins

1. Loosen the valve.

2. If necessary, loosen all components for vertical stackingabove the intermediate solenoid plate.

3. Remove the intermediate solenoid plate and turn itaround.

4. Remove the seal.

5. For external pilot air: remove the plug pins from duct 12or 14. Then insert a plug pin in duct 1.

6. For internal pilot air: remove the plug pin from duct 1.Then insert a plug pin in duct 12 or 14.

7. Insert the seal.

8. Assemble the components in reverse order.

5.6.4 Conversion, VTSA/VTSA-F valve terminal with two or more pressurezones, width 18 ...52 mm

The valve terminal can be equipped with 1 to 16 pressurezones with the widths 18 mm and 26 mm, or with 1 ... 32pressure zones with the widths 42 mm and 52 mm. Thesepressure zones are created with special seal plates with ductseparation. The following ducts can be separated with theseal plates:

– supply duct (1) only

– supply duct (1) and exhaust ducts (3) and (5)

– exhaust ducts (3) and (5) only

You can determine whether your VTSA/VTSA-F valve terminalis equipped with pressure zones via the marking on the sealingplates (position of the seal� Fig. 5/18, marking of the seal� Fig. 1/4).

In order to convert the VTSA/VTSA-F valve terminal to 2 andmore pressure zones, you will require the following compon-ents for each pressure zone:

– seal plate with duct separation VABD-...-10-P...-C

– a pneumatic supply plate with exhaust plate or exhaustcover for each pressure zone VABF-...-1P1A...




1. Disconnect the electrical and pneumatic connections andthen remove the valve terminal from the mounting surface(� Section 5.3).


3. Disconnect the manifold sub-base to which a sealing platewith duct separation is to be fitted (� Section 5.5.6).


1. Place the seal with duct separation on the guide pins ofthe manifold sub-base.

2. Mount the manifold sub-base (� Section 5.5.6).


4. Then install the electrical and pneumatic connections(� Section 3.3).

5.6.5 Conversion, valve terminal with 2 pressure zones, widths 65 mm

The valve terminal can be operated with a maximum of 2pressure zones with a width of 65 mm. These pressure zonesare formed by isolating discs, which are inserted between 2manifold sub-bases in the supply duct (1) and, for specialcases, in the exhaust ducts (3 or 5) as well.

When doing this it should be noted that the isolating disc isinserted into the manifold sub-base from the right.

– Pneumatic spring return, compressed airsupply of the pneu. spring via port (1).

Connection instructions:– for dual-pressure operation:

– supply different operating pressures toport (3) or (5).

– for vacuum operation:– either supply vacuum via port (5) and

operating pressure via port (3) or viceversa.

– the suction line (line supplied with vacuum)is to be equipped with a filter to prevent anycontamination from entering the valve.

– Ejector pulse during vacuum operation: toenable the ejector pulse a connection is tobe established between the suction line andthe pressure line via a T-piece.
