1.2 Fitting

WARNING
Before starting the fitting work, switch off the
following:

•

the compressed air supply

•

the operating voltage supply for the electronic
components (pin 1)

You can thereby avoid:
– uncontrolled movements of loose tubing

– undesired movements of the connected actuators

– undefined switching states of the electronic compo-

nents

CAUTION
The components of the valve terminal contain
electrostatic ally vulnerable elements.

•

Do not therefore touch any contact surfaces of
the plugs on the sides of the components.

•

Observe the regulations for handling electro­statically vulnerable elements.

You will then avoid damaging the valve terminal compo­nents.

VIEA-03...05 9909d 1-5

1. Input modules

PLEASE NOTE
Treat all the modules and components of the valve
terminal with great care. Pay attention in particular to
the following:

•

the screw connectors must be fitted correctly and
not subjected to mechanical stress

•

the screws must be inserted correctly (otherwise
the thread may be damaged)

•

the specified torques must be observed

•

the modules must not be offset (IP 65)

•

the connecting surfaces must be clean

(avoid leakage and contact faults).
In the case of modules and components ordered at a
later stage, observe also the fitting instructions sup­plied with the product.

Dismantling

In order to extend or convert the valve terminal, you
must dismantle the fitted valve terminal (see also fol­lowing diagram).

• Remove completely the screws of the relevant mo­dules. The modules are now held together only by
the electric plug connectors

• Pull the modules carefully and without tilting away
from the electric plug connectors.

• Replace any damaged seals.

(see also following diagram)Fitting

PLEASE NOTE

•

Place modules ordered at a later date after the
last module before the end plate.

•

Do not fit more than 12 electric modules.

Fit the modules as follows:

• Fit a new seal onto the contact surface on the right
facing the node.

1.4 Commissioning

Next to the sensor connections there is/are one/two
green LED(s). These indicate the status of the signal at
the relevant output. The meaning of the LED is as fol­lows:

Status LED Sequence Status

1.5 Diagnosis with VIGE-03-FB-8-5POL-S

In the input module type VIGE-03-FB-8-5POL-S there is
an electronic fuse in addition to the fuse in the field bus
node. If there is a short circuit in the sensor power sup­ply at the input module, this electronic fuse will prevent
the fuse in the node from burning through. The red di­agnosis LED will facilitate the locating of faults on the
valve terminal.

PLEASE NOTE:
Observe the following when using this module:
– In the event of a short circuit all 8 sensor power

supplies will be switched off

together.

– When the short circuit has been eliminated, the

sensor power supply will be switched on again

automatically.

7

At the same time as the red LED, status bit 2

will be
set depending on the field bus node used. The follow­ing field bus nodes can be used for diagnosis via the
status bit:

– FB6 - Interbus
– FB11 - DeviceNet
– FB21 - Interbus (Rugged Line connection)
Depending on the field bus node and protocol used, the

short circuit in the sensor power supply will also be re­presented protocol-specifically. For further information,
please refer to the manual for your field bus node.

3. Additional power supply 24 V/25 A

3.1 Function

PLEASE NOTE
The additional current/voltage supply can only
be used by the high-current output modules
(HC-OUTPUT and HC-OUTPUT-N).

The additiona l sup ply a nd the hig h-cur ren t out put mod ules
enable an additional 24 V/25 A to be made available for
devices with higher current consumption. High-current
outputs can then be operated independently of the
operating voltage supply on the node of the terminal
(operating voltage connection on node/pin 2 for valves
and electrical outputs PNP/0.5 A) .

PLEASE NOTE
A module for additional supply can only be used by
the high-current output modules (PNP or NPN, 2 A)
which are fitted without gaps to the left of the
additional supply.

The additional supply offers the following advantages:
– additional power supply for the high-current outputs

(modules wi th four outputs each 2 A , e.g. for hydraulic
valves)

– Individual high-current output modules can be oper-

ated independently of the central EMERGENCY
STOP function

– several additional supplies per terminal are possible

VIEA-03...05 9809c 3-3

3.2 Fitting

PLEASE NOTE
Treat all the modules and components of the valve
terminal with great care.

With the high current contacts check that:
– sockets are fitted correctly (danger of damage).
– modules are screwed together as soon as they

are connected.

– screw connectors are not distorted/mechanically

stressed.

When planning or converting the terminal, observe
the permitted combinations.

•

The following rule always applies:

maximum 12 electrical modules are permitted per
terminal (incl. additional supply).

3. Additional power supply 24 V/25 A

The following applies for the additional power supply
module:

– it can be fitted in any position to the left of the node
– several additional supply modules are possible per

terminal

The following applies to the high-current output mo­dules:

– Always fit these modules without gaps to the left of

an additional power supply.

– Several high-current output modules are possible per

additional supply (sum of all simultaneously switched
outputs max. 25 A).

– High-current output modules of types HC-OUTPUT

(PNP) and HC-OUTPUT-N (NPN) can be fitted
together as desired. Make sure in this case that the
relevant regulations are observed (e.g. EN 60204/IEC
204; see also section "Connecting the high current
output modules").

The additional electric power supply ends with the last
high-current output module. Other I/O modules can
then be fitted (see fig. 3/1).

3.3 Installation

CAUTION
Switch off the following before undertaking installation
and/or maintenance work:

•

the compressed air supply

•

the operating voltage supply on the node of the
terminal (pin 1, electronic components and pin 2,
outputs/valves)

•

if necessary, the additional 24 V/25 A supply

You will then avoid:
– undesired movement of the connected actuators

– undefined switching states of the electronic compo-

nents

– high short-circuit currents

3.3.1 Selecting the cable

PLEASE NOTE
The tables and formulae in the "Electronics Manual"
cannot be used for the additional supply cables.

Note that the current consumption of the additional
supply can amount to 25 A.

•

Use conductors with suitable diameter.

•

Avoid long distances between the power unit and
the additional supply.

3. Additional power supply 24 V/25 A

3.3.2 Connecting the additional supply

The outputs of the high-current output modules are
supplied with 24 V via this connection. The modules
must be fitted without gaps to the left of the additional
supply.

Recommendation

• Connect the oper ating voltage fo r the additional supply
to the high-current outputs via the EMERGENCY
STOP circuit.

• Fit a suitable external fuse (max. 25 A depending on
cable/conductor sectional area) to the supply cable
for the additional power supply.

3.3.4 Connecting the cable

1. Remove approx. 5 cm of the cable coating.

2. Remove approx. 5 mm of the insulation, fit end
sleeves onto the wire strands.

3. Connect the ends of the cables to the terminal pin,
making sure that proper contact is made.

4. Push the cover to the front, check that the seal is
seated correctly. Tighten both screws to comply with
safety standard IP65.

5. Pull the cable back so that there are no loops in the
housing.

6. Push the conduit thread screw connector, metal disc
and strain relief forwards and tighten them.

PLEASE NOTE
Only operate the valve terminal with additional
supply if:
– the internal 25 A fuse is installed correctly and
– the cover of the additional supply is completely

fitted (IP65).

You thereby prevent the electronic components from
being damaged by high short-circuit currents or by dirt
and humidity.

3.4 Commissioning instructions

Switching on the operating voltage

The valve terminal can also be commissioned when the
voltage for the additional supply is switched off.

CAUTION
The voltage for the internal electronic components in
the terminal is supplied via the operating voltage
connection on the node (pin 1).
The logic circuits of the high-current outputs are then
also activated. This applies even if the additional
supply is not switched on.

A control program can therefore set the outputs
before the additional supply is switched on.

Please observe these points in the following cases:

• during installation of the electrical connections, es-

pecially when the operating voltages are supplied
separately.

• when planning your control and commissioning pro-

grams.

• during servicing.

You thereby avoid undesired or undefined switching
states of the high-current outputs.

VIEA-03...05 9809c 3-15

3. Additional power supply 24 V/25 A

Recommendation
Switch on all the operating voltages of the terminal at
the same time.

PLEASE NOTE
The valve terminal recognizes automatically all
connected I/O modules when it is switched on,
but not the additional supply.

Make sure, therefore, that no more than 12 modules
are fitted on the left-hand side.

4. High-current output modules (2A)

4.1 Function

The high-currrent output modules enable devices with
high current consumption (e.g. hydraulic valves) to be
controlled. The high-current output modules are avail­able with either positive or negative logic (PNP/NPN).
They can only be operated by the addit ional 24 V/25 A
supply. This module must be fitted to the right of the
high-current output modules.

4.2 Fitting

See Chapter 3.2

VIEA-03...05 9809c 4-3

4.3 Installation

CAUTION
Switch off the following before undertaking
installation and/or maintenance work:

•

the compressed air supply

•

the operating voltage supply on the node of the
terminal (pin 1, electronic components and pin 2,
outputs/valves)

•

the additional 24 V/25 A power supply

You will then avoid:

• undesired movements of the connected actuators

• undefined switching states of the electronic compo-

nents

• high short-circuit currents

4. High-current output modules (2A)

4.3.1 Selecting the cable

PLEASE NOTE
The current consumption of the high-current outputs
can amount to 2 A. If you connect two outputs to the
double assigned output sockets, up to 4 A will flow
along the common cable (see also section
"Connecting the high-current output modules").

•

Use cables with suitable diameter

•

Avoid long distances between the load and the
high current output.

The following general rule can be used for calculating
the drop in voltage bet ween the load and the high-cur­rent output (sum of outward and return path):

The following diagrams show the different pin assign­ments of the PNP and NPN output modules. Please
observe also the circuitry examples in the Appendix.

CAUTION
Before connecting the outputs, make sure that the
relevant standards have been fulfilled (e.g. EN 60204,
IEC 204).

In this way you can prevent the connected current con­suming device from being actuated by mistake (e.g.
due to short circuit between output and protective con­ductor).

4.3.3 Pin assignment PNP

The following diagram shows the pin assignment of the
output sockets of the PNP high-current output modules.

PLEASE NOTE

•

Seal the unused sockets with a protective cap in
order to comply with standard IP65.

•

If the outputs are wired parallel, ensure that the
same cable lengths/sectional areas are used
(incl. 0 V cable). This will ensure equal loading
of the individual outputs. For parallel circuitry of
two outputs, use the double assigned output
sockets 0 and 2.

4.4 Commissioning instructions

Switching on the operating voltage

CAUTION
The voltage for the internal electronic components of
the terminal is supplied via the operating voltage
connection on the node of the terminal (pin 1).
The logic circuits of the high-current outputs are then
activated. This applies even if the additional power
supply is not switched on.

A control program can therefore set the outputs
before the additional power supply is switched on.

Please observe these points in the following cases:
– during installation of the electrical connections, especially

with separate supply for the operating voltage.

– during the planning of the control and commissioning

programs
– when servicing is necessary.
In this way , you avoid undesired or undefined switching

states of the high-current outputs.
Recommendation.

Switch on all the operating voltages for the valve termi­nal simultaneously.

VIEA-03...05 9809c 4-17

4. High-current output modules (2A)

4.4.1 Addressing/programming

PLEASE NOTE
The high-current outputs are addressed and
programmed just like the “normal” electrical
outputs of the valve terminal.

The following information supplements the details in
Chapter 4.1 of the "Electronics manual" for your valve
terminal.

Calculating the number of inputs/outputs

The digital high-current output modules (4 outputs) occupy
four outputs. The outputs are assigned automatically
within the valve terminal, irrespective of whether the
outputs are actually used.

4.4.2 Diagnosis/eliminating faults

PLEASE NOTE
The high-current outputs offer the same diagnostic
possibilities as the “normal” electrical outputs of the
valve terminal.
– LED display
– Short circuit/overload monitoring

PLEASE NOTE
The power to the high-current output modules is
supplied only via the 24 V/25 A additional supply. This
additional supply is not monitored by the terminal.

Tip for diagnosing the additional 24 V/25 A supply

• Connect an (unused) high-current output with an

input of the same type (PNP/NPN) on the valve ter­minal.

• Set this high-current output in the control program

and interrogate the signal at the appropriate input.
– Logic 1 then means:
operating voltage of additional supply is available.
– Logic 0 then means:
operating voltage of additional supply not available
(or short circuit at high current output).

4. High-current output modules (2A)

4.4.3 Short circuit/overload at a high-current output

If there is a short circuit or overload:
– the digital high-current output will be switched off.

The switch-off time depends on the load current/short
circuit.

– the short circuit error bit will be set as follows (de-

pending on the node of the terminal):
– common error SC/O (output short circuited/over­ loaded) in the status bits and/or in the diagnostic
byte or
– bit and word number of the faulty output
(short circuit/overload).

In order to activate the output again, proceed as fol­lows:

• Eliminate the short circuit or overload.

• Set the output to 0 (RESET). The short circuit error

bit of the terminal will be reset to logic 0.

• Wait at least 1 second (short circuit recovery time).

• Reset the output to logic 1. If the short circuit still

exists, the output will be switched off again.

4.5.3 Cable length and sectional area

Please observe the following when planning:

•• Observe the exact current consumption of the indi­vidual high-current outputs.
– Then select suitable cable sectional areas for the
connected current consuming devices and observe
the voltage drop.
– Use two high-current outputs on one socket:
Note that the sum current of both outputs flows on
the common cable (PNP: 0 V; NPN: 24 V).

•• Calculate the current consumption of all the simu lta­neou sl y switched high-current outputs of an additional
supply.
– Select suitable cable sectional areas for this
additional supply and observe the voltage drop.
– Use an appropriate external fuse for the additional
supply (max. 25 A).

VIEA-03...05 9809c 4-25

•• Observe the voltage drop of the complete
installation (see also following diagram). Take into
account here:
– the fluctuations in the primary mains power supply.
– the load dependency of the power unit (V
– the supply and return cable (2 x L

5. Multi I/O module (12I/8O)

5.1 Function of the multi I/O module (12I/8O)

The multi I/O module enables a large number of I/Os to
be connected at low cost with the aid of a 25-pin multipin
cable and sub-D conn e cto r plug (as per DIN 41652). Four
outputs each are grouped together and are supplied ex­ternally with 24 V. The outputs of each group are elec­trically isolated from the node. The multi I/O module is
available with either positive or negative logic
(PNP/NPN). Please note here also the circuit diagrams
in the Appendix.

5.3 Installation

WARNING
Before undertaking installation and/or maintenance
work, switch off the following:
– the compressed air supply
– the operating voltage at the node of the terminal

(pin 1, electronic components and pin 2, outputs/
valves)

– if necessary, the 24 V power supply to the outputs

of the multi I/O module.

You thereby avoid:
– undesired movements of the connected actuators

– undefined switching states of the electronic compo-

nents

5-4 VIEA-03...05 9809c

5. Multi I/O module (12I/8O)

5.3.1 Selecting the cable

PLEASE NOTE
The current consumption of each output can amount
to 0.5 A. The sum current of a group of four can
therefore amount to 2 A.
– Use conductors with appropriate diameter.
– Avoid long distances between the load and the

output.

The 25-pin sub-D socket (with PG11 screw connector)
permits the use of cables with diameter from 7...12 mm.

Recommendation:
Use the Festo cable KEA-1-25P-... with 25-pin multipin
socket. Advantages:

– ready made plug
– reduced installation costs
– cables supplied from factory in different lengths
– conforms with protection class IP65 (fitted com-

pletely)
