1 User instructionsEnglish
Valve terminal type CPV..-GE-ASI-4E4A-... has been de
signed exclusively for controlling pneumatic actuators and
is only suitable for use in bus systems in accordance with
the AS-Interface specifications. If additional commercially-
available components such as sensors and actuators are
connected, the specifiedlimits 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 ter
minal 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-sec
tional area) to the earth potential.
SCommission only a valve terminal which has been
fitted and wired completely.

3 Installation instructions
3.1 Assigning the AS-Interface address
Please note
The AS-Interface address of the valve terminal type
CPV..-GE-ASI-4E4A-... is stored electronically (no bat
tery) after every modification and can be modified at
least 10 times. After that the valve terminal maintains
the last set AS-Interface address.
We recommend that you use the Festo addresser type ASI-
PRG-ADR with adapter cable type KASI-ADR.
Before connecting to the AS-Interface bus: assign an un
used address to each slave. Set the desired address with
the AS-Interface addresser. The permitted address range is
1 ... 31.
The factory setting of the terminal is address 0. It is not
necessary to parametrize the AS-Interface slaves.

– 1 double-solenoid valve, 2 single-solenoid valves
– PLC byte #36 and AS-Interface address #5

3.3 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.
Please 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.

3.4 Connecting the AS-interface bus and the load voltage
Please note
The sensor power supply for the inputs is provided via
the AS-interface bus. Voltage suppply of the outputs
via the AS-Interface bus is only possible with type
CPV...-GE-ASI-4E4A.Type CPV...-...-Z must always be
supplied 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
Use power supplies which guarantee reliable electrical
isolation of the operating voltage as per IEC/DIN EN
60204-1. Consider also the general requirements for
PELV circuits in accordance with IEC/DIN EN 60204-1.
By the use of PELV circuits, protection against electric
shock (protection against direct and indirect contact) is
guaranteed in accordance with IEC/EN 60204-1 (Electri
cal equipment for machines, General requirements).

Festo CPV..-GE-ASI-4E4A-... 2017-11e English10
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 ccurrent consumption of the valve
terminal and the fluctuations in the load voltage).
– seal unused cable ends with the Festo cable cap ASI-
KK-FK or the cable sleeve ASI-KT-FK. In this way you
will avoid leakage currents and comply with protection
class IP65.
