1 User instructions
Valve terminal type CPV…-GE-ASI-4E3A-Z has been de
signed exclusively for controlling pneumatic actuators and
is intended for use in bus systems in accordance with the
AS-Interface specification 2.1. If additional commercially
available components such as sensors and actuators are
connected, the specified limits for pressures, tempera
tures, electrical data, torques, etc. must not be exceeded.
AS-Interface bus systems and valve terminals may only be
installed by personnel especially trained for this purpose.
Detailed information on the design and addressing of your
bus system can be found in the manual for your AS-Inter
face master.
Information on the pneumatic components of the valve
terminal can be found in the Pneumatics manual
P.BE-CPV-... .
Warning
SSwitch off the power supply before connecting or
disconnecting plugs (otherwise this could lead to
functional damage).
SConnect the earth connection on the left end plate
with low impedance (short cable with large cross-
sectional area) to the earth potential.
SCommission only a valve terminal which has been
fitted and wired completely.

3 Installation instructions
3.1 AS-Interface Addresses
Before connecting to the AS-Interface bus: assign an
unused address to each slave.
Address assignment
The assignment of the data bits to the inputs and outputs
of the slave shows the following figure:
IO code 7H
D0 D1 D2 D3
I/O I/O I/O I/O
I0 I1 I2 I3
O0 O1 O2 –
Inputs:
Outputs:
Data bits:
I/O = bi directional (B)
The address mapping depends on the configuration of the
master.
3.2 Assigning the AS-Interface address
Note
Addressing valve terminal type CPV...-GE-ASI-4E3A-... is
only permitted with addressers as per specification 2.1.
Other addressers do not permit clear access to the
slaves and in some cases overwrite the ID1 code.
Recommendation: Use the Festo addresser type
ASI-PRG-ADR with adapter cable type KASI-ADR.

Festo CPVASI4E3AZ 2018-11c English6
Factory setting: address #0, A slave
The addressing device scans the existing slaves in the
AS-Interface network.
SAssign the desired address to the slave.
It is not necessary to parametrize the AS-Interface slave.
Operation with AS-Interface masters < Spec. 2.1
Operation with AS-Interface masters < Spec. 2.1 is possible
but the slave must be programmed as A slave.
Recommendation: For operation with AS-Interface masters
< Spec. 2.1 use valve terminal type CPV...-GE-ASI-4E4A-...
instead of CPV...-GE-ASI-4E3A-... .
3.3 Address assignment of the valves
The following fittings are possible for the valve terminal:

3.4 Connecting sensors (PNP inputs)
For connecting sensors use cable type KM8-M8-GSGD-...
and plugs with union nut, M8x1 thread.
Fasten the plugs with the aid of the union nut in order to
prevent unintentional loosening, e.g. due to shock. Seal
unused sensor connections with the protective caps type
ISK-M8. Only in this way can you comply with protection
class IP65.
Note
– The inputs have been based on the IEC1131-2
type 02.
– The inputs are protected against short circuits. If a
short circuit occurs, the slave will be switched off.
The AS-Interface master regards this slave as mis
sing. When the short circuit has been eliminated, the
slave responds immediately as being operative.

3.5 Connecting the AS-interface bus and the load voltage
Note
The sensor supply derived from the ASInterface power
supply is protected against short circuits and overload.
It must not be connected to other voltages (for example
common ground).
The valves must be supplied separately with 24 V via
the load voltage connection.
The AS-interface has an integrated watchdog function
which resets the outputs if there is a bus communica
tion failure.
Warning
SUse only PELV (protective extra-low voltage) circuits
as per EN 60204-1 for the electric power supply.
SAlso observe the general requirements for PELV
power circuits as per EN 60204-1.
SOnly use power sources which guarantee reliable
electrical isolation of the operating voltage as per
EN 60204-1.
By the use of PELV circuits, protection against electric
shock (protection against direct and indirect contact) is
guaranteed in accordance with EN 60204-1.

Please note with branch lines:
– the total maximum length of the AS-Interface bus:
100 m (without repeater/extender).
– the cable length of the load voltage connection
(depends on the current consumption of the valve
terminal and the fluctuations in the load voltage).

For connecting the valve terminal use the Festo cable
sockets type ASI-SD-FK... . You will then comply with
protection class IP65. Proceed as follows:
1. Press the AS-Interface cable into the upper part of the
cable socket.
2. Make sure that the cable is free of tension.
3. Place the cable socket in position and screw it tight
(max. 0.3 Nm).
Seal open flat cable ends with the Festo cable cap type
ASI-KK-FK or the cable sleeve type ASI-KT-FK. In this way
you will avoid leakage currents and comply with protection
class IP65.
