1-4 Festo P.BE-VTSA-44-EN en 1202g 1.1 The VTSA... valve terminal Festo assists you in solving your automation tasks at machine level with VTSA... valve terminals. The modular structure of the valve terminal enables you to match it optimally in your machine or system. The valve terminal pneumatics establish the following con- nections: – Common ducts for supply and exhaust air – Electric signals from all solenoid coils The working lines (2) and (4) are provided for each valve posi- tion on the individual manifold sub-bases. The valves are supplied with compressed air (operating pressure and pilot pressure) via the common channels and connections in the pneumatic supply plates. The exhaust air (from the valves and the pilot exhaust) is also exhausted via these common channels and connections. Dependent on its width, the valve terminal can be supplemen- ted by additional pneumatic supply plates, such as to supply pressure zones. The function range at each valve position can be extended by means of additional vertical stacking components, e.g. ex- haust air flow control or pressure regulation. Valve widths The valve terminal is available with valves in the following widths:

This is necessary, for example, if the valve terminal is operated with several pressure zones or if many valves simul- taneously are switched to flow or exhausted on the valve ter- minal.

1-10 Festo P.BE-VTSA-44-EN en 1202g 1.2.2 Valves The VTSA... valve terminal can be equipped with the following 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-… can be operated as follows: – Standard operation (- 0.9 … 10 bar) – Reversible operation (- 0.9 … 10 bar). The compressed air supply for reversible operation of the VTSA… is provided via ports (3) and (5).

B/5). Tab. 1/5: Identification of the valve function in the type code 5/2-way valves with piston position sensing The monostable 5/2-way valves with ID code SO or SQ (width 26 mm) have a piston position sensing. An inductive sensor (N/C contact) monitors the neutral position of the piston spool. The sensor has a PNP or an NPN output. The valve is actuated 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 longer a signal on coil 14, the switching position 14 remains as is, since there is no spring return on control side 12. Switching position 12 is non-latching due to the mechanical spring force. Further information on the valves can be found in Appendix B.

The following ducts 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... valve terminal, the pilot control for the valves is supplied with pilot air centrally via the right end plate or via the soft-start valve. A pressure zone separation of pilot ducts (12) and (14) is therefore not possible. You can ascertain the number of pressure zones with which your valve terminal is equipped by the marking on the sealing plate (� Fig.).

B/9. 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 be built in between the manifold sub-base and valve. This pressure regulator maintains an essentially constant output pressure (secondary side) independent of supply pressure (primary side) and air consumption. The following descriptions of the pressure regulator functions are provided using the example of the pressure regulator type VABF-S4-1..C2-C-... (VTSA pressure regulator of width 18 ... 52 mm). P-pressure regulator (identifier R1-...-6 and R1-...-10) Pressurizing process The P-pressure regulator regulates the pressure in front of the valve in duct (1) (P). This provides the same regulated working air pressure in channels (2) and (4). Exhaust process: The exhaust flow in the valve is from channel (2) to channel (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, as the operating pressure is always present.

1-23 Festo P.BE-VTSA-44-EN en 1202g 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-...-6 and R4-...-10) Pressurizing process The AB-pressure regulator regulates the air pressure in ducts (4) (A) and (2) (B) after the pressure medium has passed through the valve. Exhaust process: During the exhaust process, the exhaust flows in the valve unregulated from duct (4) to duct (5) and from duct (2) to duct (3) via the pressure regulator. Restrictions: – The exhaust flow is restricted by the pressure regulating valve. – The pressure regulator cannot be adjusted in the exhaust position. For example,the pressure regulator for duct (4) cannot be adjusted when the valve is pressurised in the switching position from duct (1) to duct (2) and vented from duct (4) to duct (5). Application examples: – If two different working pressures are required at ports (2) and (4) instead of the operating pressure of the valve terminal. – If the reversible pressure regulating valve cannot be used. For example, when 2x2/2-way valves or 2x3/2-way valves with ducted solenoid exhaust (82/84) or when a flow con- trol plate is used.

1-24 Festo P.BE-VTSA-44-EN en 1202g 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 it is 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).

1-25 Festo P.BE-VTSA-44-EN en 1202g Reversible AB-pressure regulator (identifier R5-...-6 and R5-...-10) Pressurizing process With the reversible pressure regulator, the air (duct 1) is split and routed directly to both pressure regulators. In each case the regulated air is present in ducts (3) and (5) on the valve. 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) to duct (1) and in the intermediate plate guided to duct (5) or duct (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 the pressure regulator. The load on the pressure regulator is also 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. In the case of the AB-pressure regulator, the valve must switch for this. Disadvantages compared with the AB-pressure regulator: – No use of 2x2/2-way valves (ident. code: CV, VV) and 2x3/2-way valves (ident. code: K, H, N) is possible all-guides com

1-26 Festo P.BE-VTSA-44-EN en 1202g in combination with ducted solenoid exhaust (82/84), as reversible pressure is present at the valve interface. – No practical combination with an intermediate throttle plate possible. Sample applications: – When, instead of the operating pressure of the valve ter- minal, two further different pressures are required in ducts (2) and (4). – When fast venting is required. – When the pressure regulator must always be adjustable.

In the valve, the air is routed to port (2) of the manifold sub-base. The exhaust is conduc- ted via duct (4) in the pressure regulator plate and split there to ducts (3) and (5) and exhausted.

1-28 Festo P.BE-VTSA-44-EN en 1202g 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 the corresponding actuator. Vertical pressure shut-off plate This plate can be used to cut off the corresponding valve in vertical stacking from the terminal's operating and pilot pres- sure. Both duct (1) and duct (14) are shut off at the same time. This means that the valve can be removed without shut- ting off the pressure. When operating a valve terminal with a pressure shut-off plate, pay attention to the instructions in section 3.4.2. Vertical supply plate This plate can be used to supply a valve in vertical stacking with an individual operating pressure independently of the operating pressure of the terminal. 1.2.8 Components for protective functions Soft-start valves with piston position sensing The purpose of the soft-start valve type VABF-S6-1-P5A4-.. (ident. code SR) is to slowly and securely build up the supply pressure in duct (1) of the valve terminal or to quickly ex- haust duct (1) of the valve terminal.

1-29 Festo P.BE-VTSA-44-EN en 1202g Fig. 1/7: Soft-start valve The optimum pressure build-up required by the application for each pressure zone is configured directly on the valve terminal by setting the switchover pressure and filling time. The VTSA/VTSA-F valve terminal can either be operated with an internal pilot air supply via the soft-start valve or with an internal or external pilot air supply via the different end plates. The type of pilot air supply is determined by the seal of the soft-start valve. The soft-start valve is actuated electrically independently by the multi-pin/fieldbus connection via a 4-pin plug (in accord- ance with ISO 15407-1) or separately via an optional M12 adapter. Switch-on takes place in two stages: – First the working pressure provided for duct (1) gradually increases. The speed can be adjusted using a flow control screw. – 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 via the soft-start valve, the full operating pressure is always present at duct (14). This pressure causes the valves on the valve terminal to immediately move to the required switching

1-30 Festo P.BE-VTSA-44-EN en 1202g position. When the valve is not switched, duct (1) of the valve terminal is exhausted via the soft-start valve's exhaust port. The switching point for full operating pressure is set to 4 bar at the factory, but can be changed using an adjusting screw. The piston position of the soft-start valve can optionally be monitored by an inductive sensor (N/O contact). This sensor registers whether the valve has switched and therefore whether the valve terminal is being supplied with air. Due to the required calibration, the later addition of the sensor by the customer is not intended. A pressure gauge is optionally available as a pressure indicator. Note – The VTSA valve terminal can be equipped with a maxim- um of 5 soft-start valves. – If a soft-start valve is used in the VTSA valve terminal, no additional pressure-supplying components may be used in the same pressure zone. – Exhaust air cannot be expelled via the soft-start valve. If a pressure zone is operated with a separate duct (1) and 3/5 duct, 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 in the assembly instructions VABV-S6-1Q-... Control block The control block type VOFA-B26-T52-M-... (ident. code SP or SN) is intended for two-channel control of pneumatic drive components (e.g. double-acting linear cylinders) and can be used for implementing the following safety functions: – Protection against manipulation, prevention of unexpec- ted start-up (EN 1037) – Safe reversal of a hazardous movement, provided the reversing motion itself will not result in further hazards. all-guides com

Contents of this chapter The VTSA... valve terminal is factory pre-assembled. This chapter describes how to mount and dismount: – the entire valve terminal (H-rail and/or wall mounting) – The mounting bracket for wall mounting – The inscription label holders – The manual override caps Additional information Specific information about replacing or adding pneumatic components can be found in chapter 5. VTSA... valve terminal with CPX terminal or FB21 (type 03): – Information for mounting the valve terminal with CPX ter- minal can be found in the CPX system description. – Information on connecting and dismantling the I/O mod- ules can be found in the manual for the CPX I/O modules or in the additional description of type 03 I/O modules. – Information on mounting modules and components ordered at a later stage can be found in the package insert.

2.1 General instructions on assembly and dismantling Warning Sudden unexpected movements of the connected actuat- ors and uncontrolled movements of loose tubing can cause injury to human beings or damage to property. Before carrying out mounting, installation and mainten- ance work, switch off the following: – Compressed air supply – Operating and load voltage supplies. Note Handle all modules and components of the valve terminal with great care. Pay particular attention to the following: – The specified torques must be complied with. – Screw connections must be fitted without distortion and mechanical tension. Position screws exactly before tight- ening (otherwise their threads will be damaged). – The modules must not be offset (IP 65). – Contact surfaces must be clean (avoid leakage and con- tact faults). – Seal unused valve locations with the appropriate cover plate (must be ordered separately). – Electrostatically sensitive devices. Therefore do not touch any contact areas. – Valve terminals with Sub-D multi-pin node: Protect the multi-pin node from moisture, dirt, dust, etc. until the multi-pin plug socket is fitted with a cable. all-guides com

2.2 Mounting variants You can mount the VTSA... valve terminal in one of two ways: Mounting method Description Hat rails Apart from the VTSA valve terminal with FB 21 (type 03) and the valve terminal with pneumatics in a width of 65 mm, all of the other valve terminal variants are suitable for mounting on an H-rail (mounting rail according to EN 60715). Please observe the safety instructions in the following section for further informa- tion. A guide groove is located at the rear of the valve terminal for connecting it to the H-rail. Wall Width 18 ... 52 mm: The multi-pin node, the pneumatic interface and the end plates contain holes for mounting the terminal onto a wall. Additional mounting brackets on the pneumatic supply plates may be required for valve terminals with more than 5 manifold sub-bases (� subsequent information and specifications regarding vibration and shock can be found in Appendix A, Tab. A/5. Width 65 mm The adapter, the manifold sub-bases and the pneumatic interface include holes for wall mounting. When mounting on machines or metal frames also use the blind holes on the rear of the manifold sub-bases (rear mounting). Fig. 2/1: Methods of mounting the VTSA... valve terminal Note Mount the VTSA... valve terminal in such a way that en- sures sufficient space for heat dissipation and compliance with the temperature limit values (� Appendix A, Technic- al data).

2.2.1 Mounting/dismounting on H-rails Note H-rail mounting is not intended for the following VTSA valve terminals: – VTSA with type 03 electronics – VTSA with valves in a 65 mm width Use the wall mounting method for these valve terminals. Caution – Make sure that the H-rail can support the weight of the VTSA... valve terminal and can absorb torsion e.g. through the vertical stacking. – When mounting the valve terminal onto an H-rail, note the specifications in standard EN 60715 and the specific- ations on vibration and shock in the section “Technical specifications” in Appendix A. – H-rail mounting without an H-rail clamping unit is not permitted. • If the mounting position is inclined or the unit is subjec- ted to vibrating loads, secure the H-rail clamping unit - from shifting by using the provided safety screws (� Fig. 2/1, number 2) - against unintentional loosening/opening. In order to mount the valve terminal onto an H-rail you will require the following mounting kits: – for VTSA... valve terminals with multi-pin node: mounting set type CPA-BG-NRH. This set consists of 2 x M4x10 screws and 2 clamping components. – for VTSA... valve terminals with CPX terminal: mounting set type CPX-CPA-BG-NRH This set consists of 3 x M4x10 screws and 3 clamping components.

Caution Overloading the mounting holes, bending the VTSA... valve terminal with CPX terminal or internal vibrations can cause damage. • In such cases use the additional mounts for the CPX terminal (� information in the CPX system description). • VTSA (width 18 ... 52 mm) with metal CPX interlinking block: On every fourth VTSA component (manifold sub-base or supply plate), use the mounting bracket type: VAME-S6-W-M46. The manifold sub-bases and pneumatic supply plates have corresponding threaded holes (tightening torque 3.0 Nm) for mounting the brackets. • All other VTSA units in width 18 ... 52 mm: Additional mounting brackets of type VAME-S6-10-W are to be used depending on the number of valve positions (� Appendix A, Tab. A/5). The manifold sub-bases and pneumatic supply plates have corresponding threaded holes (tightening torque 3.0 Nm) for mounting the brack- ets. • All other VTSA units in width 65 mm: Use the mounting holes in at least every second mani- fold sub-base. The following components contain holes for wall mounting (� Tab. 2/17). – End plates – Pneumatic interface – Multi-pin node – Manifold sub-bases, width 65 mm

Mounting Proceed as follows: 1. Make sure the mounting surface is flat and that it can support the VTSA... valve terminal (weights � Appendix A, Tab. A/2). Make sure there is sufficient space for connecting the power supply cables and tubing. 2. Drill mounting holes in the mounting surface. 3. Secure the valve terminal to the mounting surface using screws of the appropriate length (� Tab. 2/17).

Contents of this chapter This chapter describes the tubing and cabling of the VTSA... valve terminal. This includes in particular the following: – General instructions on compressed air preparation and tubing connections – Instructions on pilot control with internal or external pilot air supply – Instructions on operating the valve terminals with pres- sure zones – Instructions on operating the valve terminal with revers- ible 2x3/2-way valves – Fitting the QS threaded connectors – Connecting the power supply – Earthing the valve terminal – Address assignment of the valves Additional information Instructions on connecting the electrical components of the VTSA... valve terminal with multi-pin node can be found in the relevant information supplied with the product. Requirements for observing the certified UL conditions if the product is operated in the USA or Canada can be found in the separate special UL-specific documentation. Instructions on connecting the operating voltage for the VTSA... valve terminal with CPX terminal can be found in the CPX system description, chapter 3. Detailed instructions on how to connect CPX modules (bus nodes, I/O modules, etc.) can be found in the corresponding CPX module descriptions. Detailed instructions for connecting type 03 modules (bus nodes, I/O modules) can be found in the corresponding descriptions for the type 03 module.

3.1 Compressed air preparation Caution Unfiltered or incorrectly lubricated compressed air will reduce the service life of the valve terminal. 3.1.1 Operation with unlubricated compressed air Note Too much residual oil content in the compressed air will reduce the service life of the valve terminal. – When using bio-oils (oils that are based on synthetic ester or native ester, e.g. rapeseed oil methyl ester), the maximum residual oil content of 0.1 mg/m3 should not be exceeded (� ISO 8573-1-2010 class 2). – When using mineral oils (e.g. HLP oils to DIN 51524 Part 1 to 3) or corresponding oils based on polyalphaolefin (PAO), the maximum residual oil content of 5 mg/m3 should not be exceeded (� ISO 8573-1-2010 class 4). This avoids operative malfunction of the valves. Excessive residual oil is not permissible irrespective of the compressor oil, as otherwise the basic lubrication will be washed 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 pneumat- ic valves and actuators have been designed so that, if used as intended, they will not require additional lubrication and will still achieve a long service life.

Caution Operation with lubricated compressed air will cause the life-time lubrication, which is necessary for unlubricated operation, to be “washed out”. Note the following instructions if lubricated compressed air must be used. The compressed air produced after the compressor must comply with the quality of unlubricated compressed air. If possible, do not operate all of your equipment with lubricated compressed air. If possible, always install the lubricators dir- ectly upstream of the consuming actuator. Caution Incorrect additional oil and too much residual oil content in the compressed air will reduce the service life of the valve terminal. – Use Festo special oil OFSW-32 or the alternatives listed in the Festo catalogue (as per DIN 51524-HLP32, basic viscosity 32 CST at 40 °C). – 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 malfunction of the valves. Setting the lubricator 0.2 to max. 1 drop/min. or 0.5 to 5 drops/1000 l of air when the machine is running (typical operating status). Checking the setting The procedure described below can be used to check the lubricator setting. Proceed as follows: • Check the service units for condensate and lubricator setting twice a week. 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 ex- haust port. 5. Let the system run for a short period. – There must be only a slight yellow colouring on the cardboard. If oil droplets appear, this is an indication that too much oil has been used. Another indicator of over-lubrication is the coloration or the condition of the exhaust air silencer. A distinctly yellow col- ouring of the filter element or drops of oil on the silencer in- dicate that the lubricator setting is too high. all-guides com

3.2 General notes on connecting the tubing Warning Uncontrolled movements of the connected actuators and loose tubing can cause injury to persons and/or damage to property. Before carrying out mounting, installation and mainten- ance work, switch off the following: – Compressed air supply – Operating and load voltage supplies. Note Observe the following if the UL requirements are to be complied with in your application: – Rules for observing the UL certification can be found in the separate UL-specific documentation. The relevant technical specifications 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 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. Back pressure When exhausting large volume actuators or if the exhaust performance is too small, back pressures can build up in the valve terminal exhaust ducts. The back pressures can lead to pneumatic actuation of other valves, especially with un- switched 3/2-way valves that are normally closed.

To avoid back pressures: • Optimise the pressurisation and ventilation capacity of the valve terminal, for example, by using larger diameter tubing or an additional compressed air supply via pneu- matic supply plates with venting via a silencer or exhaust plate. • Separate the exhaust ducts, if necessary, by using pres- sure zones (� section 1.2.5). 3.2.1 Installing the tubing If elbow connectors or multiple distributors are used, the air flow will be reduced slightly. Connection Proceed as follows: 1. Push the tubing as far as possible into or over the tube coupling of the fitting. 2. Depending on connection: – If necessary, pull the locking ring 1 over the tube coupling (� Fig. 3/1). – Tighten the clamping screw 2 (� 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 clamp 3 3. For a better overview of the system group the tubing to- gether with: - tubing straps or - multi-tube holders

Disconnection Proceed as follows: Warning If the pneumatic tubing is under pressure when dismoun- ted, it may perform sudden unexpected movements, caus- ing injury to persons. Carry out the following steps before disconnecting the pneumatic tubing on the valve terminal: • Deactivate compressed air supply. • Make sure that all pneumatic tubing is unpressurized. • Exhaust all actuators controlled by valves that are blocked in the neutral or middle positions. 1. Mark all pneumatic tubing. 2. Depending on connection: – Press down the locking ring of the threaded connector 1, e.g. with a Festo QSO releasing tool. – Loosen the clamping screw 2 of the threaded con- nector. – Loosen the hose clamp screw 3. 3. Remove the tubing from the threaded connector. 4. Seal threaded connectors that are not required with blanking plugs 4.
