ValveterminaltypeVTUG-PT-L

1 Range of application and certifications

The VTUG valve terminal with interlock (type VTUG-PT-L) is used exclusively for
control of pneumatic actuators within the limits of the technical data and is inten­ded for installation in machines and automation systems.
The VTUG-PT-L is intended for use in an industrial environment.
The target group of this description consists of trained specialists in control and
automation technology who have experience with the installation of valve terminals.

War n ing

Danger of injury through uncontrolled movements of connected equipment.
Make sure that electrical and pneumatic equipment are in a de-energised and
pressureless status.
Before working on the pneumatics:

• Switch off the compressed air supply

• Vent the valve terminal
Before working on the electrical co mponents, e.g. before installation or mainten­ance work:

• Switch off the power supply
In this way, you can avoid:
– uncontrolled movements of loose tubing
– accidental and uncontrolled movements of the connected actuators
– undefined switching states of the electronics
– functional damage.

Note

Installation and commissioning should only be carried out by qualified personnel
in accordance with this brief description. Commission a valve terminal only if it
has been completely mounted and wired! Employ the valve terminal VTUG-PT-L
only in conformity with protection class IP40.

Note

IO-Link® a nd TORX® are registered trademarks of the respective trademark
owners in certain countries.

Note

Certain configurations of the product have been certified by Underwriters Labor­atories Inc. (UL) for the USA and Canada ( Title).
If the UL requirements are to be complied with in your application, please ob­serve the regulations of the separate U L-specific special documentation. The
relevant technical data listed there also apply here.

2 Pilot air supply for pilot control

The VTUG valve terminalis configured for operation with internal or external pilot
air depending on your order.

Internal pilot air supply

The pilot pressure is branched from duct 1 for internal pilot air supply. If your VTUG
valve terminal is configured for internal pilot air supply, the ports 14 in the mani­fold rail are sealed with blanking plugs.

External pilot air supply

The pilot pressure is supplied via port 14 for external pilot air supply. If your VTUG
valve terminal is configured for external pilot air supply, a special blanking screw is
fitted in the manifold rail (



Fig. 1). Conversion of the pilot air variant is described

in the assembly instructions VABM-L1-...GR.

3Pressurezones

Using separators, the valve terminal VTUG-… can be divided into pressure zones.
Mountingof these separators is described in the assemblyinstructions VABD-... B.

4H-railmounting

The VTUG-PT-L valve terminal is designed for mounting on an H-rail.

Note

If the VTUG-PT-L is subjected to vibration or shock loads, H-rail mounting is not
permissible.

H-rail mounting is described in the assembly instructions VAME-T-M4.

7 Earth terminal

Connect the VTUG-PT-L to the functional earth via the earth terminal ( 4 in
Fig. 1). In this way, you will avoid malfunctions from electromagnetic interference.

8 Voltage supply

Note

• Use for the electrical power supply only PELV circuits in accordance with
IEC/EN 60204-1 (Protective Extra-Low Voltage, PELV).

• Observe also the general requirements for PELV circuits in accordance with
IEC/EN 60204-1.

• Use only voltage sources that ensure a reliable electric separation of operat­ing voltage in accordance with IEC/EN 60204-1

• Always connect both circuits for operating and load voltage supply.

Through the use of PELV circuits, protection against electric shock (protection
against direct and indirect contact) is ensured in accordance with IEC/EN 60204-1.

9 I-port connection

The VTUG-PT-L can be connectedas followsvia the I-port connection:
– directly to the fieldbus by mounting a CTEU bus node on the VTUG-PT-L
– decentralised to an external I-port-compatible device through a connecting

cable.

– to a CPX terminalthrough a connecting cable and a CTEL master module

( CTEL system description).

The VTUG-PT-L can also be operated as an IO-Link device. You can download the
IODD configuration file required for this at  www.festo.com.

Note

If an IO-Link Master is used, the load voltage must normally be made available
through a T-plug.

11 Inscriptionlabels

The valves of the VTUG-... can be equipped with an inscription label holder (



as-

sembly instructions ASCF-H-L1) or with identification plate holders (



assembly
instructions ASLR-D). The I-port sub-base can be equipped with the identification
plate ASLR-C-E4.

12 Manual override (MO)

Actuation of the MO under the holders of the inscription label holder ASCF-H-L1 or
under the identification plate holders ASLR-D, is only possible in a non-detenting
manner.
The MO VAMC-L1-CD is not permissible in combination with the inscription label
holder ASCF-H-L1.

Note

Declaration of conformity

(www.festo.com)

Materials AL, PA, POM , NBR, PU, PC

1) If the VTUG-... is operated with external pilot air, the pressure of the pilot air must be at least 50 % of
the operating pressure

2) Reduce your pilotpressure to max. 6 bar if there are more than 12 simultaneously switched valves.

3) The operating voltage supply is provided via the CTEU bus node or IO-Link Master. The load voltage
supply is provided via the CTEU bus node or, for IO-Link, via a separate feed. Separate fuses are re­quired for operating and load voltage.

4) The VTUG... valve terminal is intended for use in an industrial environme nt. Outside of industrial envir­onments, e.g. in commercial and mixed-residential areas, actions to suppress interference may have to
be taken

17 Interlock

The first 16 solenoid coils can be supplied individuallythrough the interlock Sub-D
plug c onnector. This permits the external release of these valves.

Note

Only mount or remove the interlock Sub-D socket when the power is switched
off.

The interlock can be switched on as follows:
– single-pinthrough external contacts
– double-pin through safe output terminals. In this case, check the compatibility

of the safe output terminals with the VTUG-PT-L.
All valves of the VTUG-PT-L are supplied with load voltage via the interlock Sub-D
plug connector, even if they are actuated via the bus node. The solenoid coils
17 … 32 and 33 … 48 cannot be supplied individually through the interloc k S ub-D
plug connector ( table in section 17.3 and 17.4).

17.1 Sub-D socket

Festo recommends one of the following connecting cables (with sub-D socket)
from Festo for connecting the interlock.

17.3 Single-pin interlock interface

Observe the following with single-pin interlock interface:
– The interlock interface is made through external plus switching contacts or

single-pin switching safety terminals.
– The 24 V supply of all solenoid coils must be on the same potential.
– 16 solenoid coils can be actuated through the interlock (V

n

+).

– The solenoid coils that do not require an interlock interface can be supplied

directly with 24 V from pin 1 … 3.
– Creation of the respective input voltage is reported as an image table through

the fieldbus.

Note

The interlock contacts V1– … V16– must not be used with the single-pin interlock
interface.

For an example of a circuit diagram for a single-pin interlock interface  Fig. 12.

17.4 Double-pin interlock interfac e

Observe the following with the double-pin interlock interface:
– The interlock interface is made through external plus-minus switching safety

terminals.

Note

Internal activation of valves 1 … 16 via the fieldbus must not be used.
Inadvertent actuation of the internal drivers of the VTUG-PT-L via the fieldbus
can be detected by most safe terminals. Only use terminals that detect inadvert­ent actuation via the fieldbus.

– The solenoid coils of the interlock valves are controlled via the corresponding

pin in the Sub-D plug c onnector (pins 7 … 38).

– The solenoid coils that do not require an interlock interface can be supplied

directly with 24 V (e.g. from pin 1 … 3).

– A difference in potential between V

n

–and0V

VAL/OUT

is permissible only below

5V.

– The test impulses (

≤

1 ms) used for error detection by safe output terminals are

suppressed by a special filter switch.

– The current consumption for each valve is below 20 mA on the VTUG-PT-L. Some

safe terminals detect a wire break if current consumption is below 20 mA. In
these cases, the wire break detection must be switched off.
