1. Overview of components

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 con­nections:

– Common ducts for supply and exhaust air

– Electric signals from all solenoid coils

The working lines (2) and (4) are provided for each valve posi­tion 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 supplemen­ted 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. ex­haust air flow control or pressure regulation.

Valve widths The valve terminal is available with valves in the following

widths:

Tab. 1/1: Widths

For the combination of widths 18 ... 52 mm on the
valve terminal, no adapter plate is required.

The 65 mm width (ISO 3) is an adaptation of the pneumatics
of valve terminal type 04-B. In order to combine these widths
with smaller widths, adapter type VABA-S6-7-S2-3-... is re­quired.

The VTSA... valve terminal is available with the following num­ber of valve positions depending on the manifold sub-bases
used and the electrical connection variant.

1.2.5 Pressure zone separation

Using special seal plates, you can divide the VTSA… valve
terminal into pressure zones ( 3.8). 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 sealin g
plate ( Fig.).

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.

1-22

Festo P.BE-VTSA-44-EN en 1202g

1. Overview of components

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.

Festo P.BE-VTSA-44-EN en 1202g

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 con­trol plate is used.

1-23

1. Overview of components

Fig. 1/5 shows the following switching position of the B-pres­sure regulator:
The working air is passed from duct (1) through the interme­diate plate and the valve to the B-pressure regulator, where it
is regulated and then passed to port (2) of the manifold sub­base. The exhaust is passed via duct (4) to pressure regulat­ing valve A and then via the valve to duct (5).

1. Overview of components

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 por t (2)

– Duct (5) routes the working pressure to por t (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.

Festo P.BE-VTSA-44-EN en 1202g

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

1-25

1. Overview of components

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.

The example below shows the following switching position:

to port (2) of the manifold sub-base. The exhaust is conduc­ted via duct (4) in the pressure regulator plate and split there
to ducts (3) and (5) and exhausted.

Flow control plate

This plate is used in vertical stacking for exhaust air flow con­trol 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 pres­sure. Both duct (1) and duct (14) are shut off at the same
time. This means that the valve can be removed without shut­ting 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 ex­haust duct (1) of the valve terminal.

1-28

Festo P.BE-VTSA-44-EN en 1202g

1. Overview of components

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.

Festo P.BE-VTSA-44-EN en 1202g

The soft-start valve is actuated electrically independently by
the multi-pin/fieldbus connection via a 4-pin plug (in accord­ance 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 oper­ating 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

1-29

1. Overview of components

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
inthesamepressurezone.

– 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.

ic supply plate and the right end plate can be found in

The number of electrically controllable valve positions de­pends on the manifold sub-bases and the electrical connec­tion used ( Tab. 1/2).

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

If, on the other hand, only manifold sub-bases that control
only one solenoid coil per valve position are used, the valve
terminal can only be equipped with monostable 5/2-way
valves (ident. code M or O) or cover plates.

1.3.4 Vertical stacking

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

You can mount further pneumatic components in each loca­tion between the manifold sub-base and the valve. These
vertical stackings enable you to implement certain additional
functions as desired. The following diagram shows the avail­able components:

1. Overview of components

The vertical stacking components of width 65 mm are desig­nated by a type code on the valve terminal. The code is prin­ted on the side of the component. Identification within the
type code indicates the function of the components, e.g. type
code LR-ZP-A-D-3 indicates that this component is an A-pres­sure regulator. Y o u can identify the vertical stacking compon­ents with the aid of the following table. In the sales docu­mentation and in the Festo Configurator, the components are
marked with an ID code.

2.1 General instructions on assembly and dismantling

Warning

Sudden unexpected movements of the connected actuat­ors and uncontrolled movements of loose tubing can cause
injury to human beings or damage to property.

Before carrying out mounting, installation and mainten­ance 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.

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
–VTSAwithvalvesina65mmwidth
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:

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/m
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/m
should not be exceeded
( ISO 8573-1-2010 class 4).

This avoids operative malfunction of the valves.

should not

3

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 pneumat­ic 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.

3-4

Festo P.BE-VTSA-44-EN en 1202g

3. Installation

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 dir­ectly 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/m

3

(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.

Festo P.BE-VTSA-44-EN en 1202g

3-5

3. Installation

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

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 col­ouring of the filter element or drops of oil on the silencer in­dicate that the lubricator setting is too high.

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 mainten­ance 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.

Pleasenotethefollowing:
The components of the valve terminals contain electrostatic­ally 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 electro­statically 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 un­switched 3/2-way valves that are normally closed.

Festo P.BE-VTSA-44-EN en 1202g

3-7

3. Installation

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 pneu­matic supply plates with venting via a silencer or exhaust
plate.

•

Separate the exhaust ducts, if necessary, by using pres­sure 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.

3-8

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).

Disconnection Proceed as follows:

Warning

If the pneumatic tubing is under pressure when dismoun­ted, it may perform sudden unexpected movements, caus­ing 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.

3-10

– 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.
