1Instructions on this description

This description includes information for mounting the bus node on an I-port-com

patible device from Festo (e.g. valve terminal with I-port interface) and for installa

tion of this combination in a higher-level control system.

2Intended use

The bus node type CTEU-AS has been designed exclusively for use as a slave on

the AS-interface fieldbus. It may only be used in its original status without unau

thorised modifications and only in perfect technical condition.

The bus node is intended for use in an industrial environment. Outside of industrial

environments, e.g. in commercial and mixed-residential areas, actions to suppress

interference may have to be taken.

3Target group

The target group for this description consists of trained specialists in control and

automation technology who have experience with installation of stations on the

AS-interface fieldbus.

4Mounting

Warning

Danger of injury to people, damage to the machine and system resulting from

uncontrolled movements of the actuators and undefined switching states

Switch off the operating and load voltage supplies.

Switch off compressed air supply.

Exhaust the pneumatics valve terminal.

Note

Damage to the electronics

The bus node includes electrostatically sensitive devices.

Do not touch any electrical/electronic components.

Observe the handling specifications for electrostatically sensitive devices.

Note

Use cover caps to seal unused connections. You will then achieve degree of pro

tection IP65/IP67.

Information on mounting the bus node on the decentralised electrical

connecting plate CAPC-... can be found in the mounting instructions that

accompany the connecting plate.

The bus node CTEU-AS supports only the X1 connection of the electrical

connecting plate CAPC-.... The X2 connection on the electrical connecting

plate CAPC-... is without a function for the CTEU-AS bus node.

For mounting the bus node on a valve terminal with I-Port interface, proceed as

follows:

1.Inspect the seals and sealing surfaces on bus node and valve terminal.

2.Plug the bus node onto the valve terminal in the right position and without tilt

ing.

3.Screw the three self-tapping screws in by hand. You can use the threads already

present when you screw it in again.

4.Tighten the screws by hand in diagonally opposite sequence, with a tightening

torque of 0.7 ± 0.1 Nm.

5Connection and display components

The following electrical connection and display components can be found on the

bus node:

The bus node also supplies voltage to equipment connected via the I-port inter

face.

Warning

Danger of electric shock

Only use PELV circuits in accordance with IEC/EN 60204-1 (protective extra-

low voltage, PELV) for the electrical power supply.

Observe also the general requirements for PELV power circuits in accordance

with IEC/EN 60204-1.

Only use voltage sources which guarantee reliable electrical isolation of the

operating voltage in accordance with IEC/EN 60204-1.

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.

Observe with branch lines:

–the maximum overall length of the AS-interface bus (100 m without repeater/

extender)

–the line length of the load voltage connection cable (depends on the current

consumption of the valve terminal and fluctuations in load voltage).
