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 inten-
ded 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.
Warning
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 components, e.g. before installation or mainten-
ance 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.

owners in certain countries.
Note
Certain configurations of the product have been certified by Underwriters Labor-
atories Inc. (UL) for the USA and Canada (Title).
If the UL requirements are to be complied with in your application, please ob-
serve the regulations of the separate UL-specific special documentation. The
relevant technical data listed there also apply here.
2 Pilot air supply for pilot control
The VTUG valve terminal is 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 mani-
fold 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.
Mounting of these separators is described in the assembly instructions 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 (4in
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 operat-
ing 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 connected as follows via 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 terminal through 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 Inscription labels
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
Destruction of the MO
• Observe the permissible actuating force of max. 20 N.
13 Address assignment

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 pilot pressure 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 re-
quired for operating and load voltage.
4) The VTUG... valve terminal is intended for use in an industrial environment. Outside of industrial envir-
onments, 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 individually through the interlock Sub-D
plug connector. 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-pin through 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 interlock Sub-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.
Type Length of the cable
NEBV-S1G44-K-2.5-N-LE44-S6 2.5 m
NEBV-S1G44-K-5-N-LE44-S6 5m
NEBV-S1G44-K-10-N-LE44-S6 10 m
Fig. 9
Note
Please observe the following when using a sub-D socket from another manufac-
turer:
– the sub-D socket must not exceed a max. width of 16.5 mm
– connect the cable screening to the plug housing

Fig. 11

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 interface
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 inadvert-
ent actuation via the fieldbus.
– The solenoid coils of the interlock valves are controlled via the corresponding
pin in the Sub-D plug connector (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.
