1 User instructionsEnglish

Valve terminal type CPV..-GE-ASI-8E8A-Z M8 has been designed exclusively for controlling pneumatic actuators andis only suitable for use in bus systems in accordance withAS-Interface specifications. If used together with additional commercially available components, such as sensorsand actuators, the specified limits for pressures, temperatures, electrical data, torques etc. must be observed.

AS-Interface bus systems and valve terminals may only beinstalled by personnel especially trained for this purpose.Specifications on the design and addressing of your bussystem can be found in the manual for the AS-Interfacemaster.

Detailed information on the pneumatics of the valve terminal can be found in the pneumatics manual P.BE-CPV-....

Warning� Switch off the power supply before connecting or

disconnecting plugs (this will prevent functionaldamage).

� Connect the earth connection on the left end platewith low impedance (short cable with large cross-sectional area) to the earth potential.

� Commission only a valve terminal which is fitted andwired completely.

3 Installation instructions

3.1 AS-Interface addresses

Before connecting to the AS-Interface bus: assign an unused address to each slave.

Please note‒ Valve terminal type CPV..-GE-ASI-8E8A-Z M8 contains

2�AS-Interface slaves coupled together. The CPV-...behaves on the AS-Interface bus like two individualvalve terminals each with 4 inputs and 4 outputs(valve locations).Assignment of the inputs and outputs (valves):– slave 1: Inputs I0 ... I3; Outputs O0 ... O3– slave 2: Inputs I4 ... I7; Outputs O4 ... O7.

‒ Automatic addressing with the function “Automaticaddress assignment” of the master is not possible.

‒ It is not necessary to parametrize the AS-Interfaceslaves.

Address assignment

The assignment of the data bits to the inputs and outputsof both independent slaves is shown in the following diagram.

Slave 1: IO code 7H Slave 2: IO code 7HD0 D1 D2 D3I/O I/O I/O I/O

I0 I1 I2 I3

O0 O1 O2 O3

Inputs:

Outputs:

Data bits:D0 D1 D2 D3I/O I/O I/O I/O

I4 I5 I6 I7

O4 O5 O6 O7

I/O = Bidirectional (B)

The address mapping depends on the configuration of themaster.


Address selector button

With the address selector button and the usual addressingdevices, you can also access slave 2, providing this has ahigher address or the same address as slave 1. Press thebutton in order to unlock it. Slave 1 will then be uncoupledfrom the AS-Interface bus. If the AS-Interface bus voltageis connnected, this status will be indicated by the addressselector LED which will light up.

Please noteThe red address selector LED must not light up whenthe valve terminal is operating. Lock the address selector button therefore by pressingit again before the valve terminal is connected to theAS-Interface bus.

3.2 Assigning the AS-Interface addresses withaddressing devices ≥ Spec. 2.1

Recommendation: For addressing use addressing devicetype ASI-PRG-ADR with adapter cable type KASI-ADR fromFesto.

The addressing device scans the available slaves in theAS-Interface network.

� Assign the desired addresses to the two slaves oneafter the other.


If by mistake, the same address is assigned to both slaves,clear access to the slaves is no longer possible. In this caseproceed as follows:

1. Use the address selector button to uncouple slave 1from the AS-Interface bus.

2. Modify the address of slave 2.

3. Lock the address selector button again, in order tocouple slave 1 to the AS-Interface bus again.

3.3 Assigning the AS-Interface addresses withaddressing devices < Spec. 2.1

Caution‒ Slave 1 must never have address #31. Otherwise

further modification of the addresses is no longerpossible.

‒ For faultless operation the addresses must beassigned consecutively (e.g. slave 1: #5; slave 2: #4or slave 1: #4; slave 2: #5).Recommendation: Select the addresses so that acomplete byte in the PLC address range is assignedto the valve terminal.


When using addressing devices < Spec. 2.1: The addressing device scans the available slaves in theAS-Interface network. However, with valve terminal typeCPV..-GE-ASI-8E8A-Z M8, only the slave of the two coupledslaves with the lower address will be displayed.

Proceed as follows when setting or modifying theAS-Interface addresses.

Valve terminal as supplied from the factory(addresses�#1/#2)

1. The addressing device recognizes slave 1 with address�#1. Assign the desired address #n to slave 1.

2. When slave 1 has been addressed, the addressingdevice recognizes slave 2 with address #2. Assign aneighbouring address #m=n±1 to slave 2.

Modifying addresses

If before or during modification to the addresses, theaddress of slave 1 is higher than the address of slave 2:

� Consider the following limits by “uncoupling” slave 1as the first step in the re-addressing and assigning ahigher address to slave 2 (e.g. #31). Otherwise furthermodification of the addresses is not always possible.


– Only slave 1 can be “uncoupled” from the AS-Interfacebus with the address selector button.

– If both slaves are “coupled” to the AS-Interface bus,the addressing device can only access reliably thelower slave address. Only if slave 1 is uncoupled, canaccess also be made to a higher slave address ofslave�2. If slave 1 has the address #0, slave 2 isdeactivated.

– If by mistake the address #31 is assigned to slave�1,this address can no longer be modified, because access can then only be made to slave 2 with the loweraddress.

Example:

Old addresses: slave 1: #5; slave 2: #4:slave 2 } #31, slave1 } #3, press button, slave 2 } #2, press button, address modified

3.4 Address assignment of the valves

When addressed, the valve terminal type CPV-..-GE-ASI-8E8A-Z M8 behaves like two individual slaves eachwith 4 inputs and 4 outputs (see 3.1).

Both valve terminal halves can be fitted with equipment asfollows:

3.5 Connecting sensors (PNP inputs)

Use cable type KM8-M8-GSGD-... and plug with union nutand M8x1 thread for connecting sensors.

Fasten the plugs/sockets with the aid of the union nut inorder to prevent unintentional loosening, e.g. due toshock. Seal unused sensor connections with the protectivecaps type ISK-M8. Only in this way can you comply withprotection class IP65.

Please noteThe inputs are protected against short circuit. In theevent of a short circuit the slave will be switched off.The AS-Interface master regards this slave as faulty.When the short circuit is eliminated, the slave respondsimmediately as being functionable.

3.6 Connect the AS-Interface bus and the load voltage

Please noteThe sensor supply for the inputs is provided via theAS-Interface bus.The valves must be supplied separately with 24 V viathe load voltage connection.The AS-Interface has an integrated watchdog functionwhich resets the outputs if the bus communicationfails.

WarningUse power supplies which guarantee reliable electricalisolation of the operating voltage as per IEC/DIN EN60204-1. Consider also the general requirements forPELV circuits in accordance with IEC/DIN EN 60204-1.

By the use of PELV circuits, protection against electricshock (protection against direct and indirect contact) isguaranteed in accordance with IEC/EN 60204-1 (Electrical equipment for machines, General requirements).


Note the following with branch lines:

– Maximum total length of the AS-Interface bus: 100 m(without repeater/extender).

– Length of cable for load voltage connection (dependson the current consumption of the valve terminal andthe fluctuations in the load voltage).

Use cable sockets type ASI-SD-FK... from Festo for connecting the valve terminal. You will then comply withprotection class IP65. Proceed as follows:

1. Press the AS-Interface cable into the upper part of thecable socket.

2. Lay the cable free of stress.

3. Replace and screw tight the cable socket (max. 0.3 Nm).

Seal open flat cable ends with cable cap type ASI-KK-FK orcable sleeve type ASI-KT-FK from Festo. You will then avoidleakage currents and comply with protection class IP65.
