1 User instructionsEnglish
Valve terminal type CPV..-GE-ASI-4-... has been designed
exclusively for controlling pneumatic actuators and is only
suitable for use in bus systems in accordance with the
AS-Interface specifications. The maximum values specified
for pressures, temperatures, electrical data, torques etc.
must be observed.
AS-Interface bus systems and valve terminals may only be
installed by personnel especially trained for this purpose.
Detailed information on the design and method of addres
sing your AS-Interface bus system can be found in the man
ual for your master.
Detailed 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 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 Addressing the AS-Interface valve terminal
type10
3.1 AS-Interface addresses
Before connecting to the AS-Interface bus: assign an un
used address to each slave.
Address assignment
The diagram below shows the assignment of the data bits
to the inputs and outputs.
IO code 8H
D0 D1 D2 D3
OOOO
O0 O1 O2 O3
Outputs: (valve solenoid coils)
Data bits:
The address mapping depends on the configuration of the
master.
3.2 Assigning the AS-Interface address
Recommendation: Use the addresser type ASI-PRG-ADR
with adapter cable type KASI-ADR from Festo.
The addresser scans the existing slaves in the AS-Interface
network.
SAssign the desired address to the slave
(factory setting: address #0).
The AS-Interface slave can be parametrized,
see section 3.4.

3.4 Diagnosis and parametrizing
Valve terminal type CPV..-GE-ASI-4-... supports the evalu
ation of valve faults.
Any valve faults which occur will be registered as periph
eral faults of the slave on the AS-Interface master.
The following valve faults are monitored:
– short circuit on the valve solenoid coil,
– wire fracture on the vale solenoid coil,
– valve does not switch (no movement of the plunger).
The diagnosis of the valve module can be deactivated via
the AS-Interface parameter port P3.
Parameter port P3 Description
P3 = 1
(diagnosis active,
factory setting)
Valve faults are registered as periph
eral faults and displayed via the fault
LED (see section 2).
P3 = 0
(diagnosis inactive)
Valve faults are not registered as pe
ripheral faults and are not displayed
via the fault LED.

4 Installation
4.1 Load voltage connection (additional supply)
As from hardware status HW 0105, the setting of a DIP
switch determines the connection via which the load volt
age supply for the outputs (valve solenoid coils) is pro
vided, see section 4.2.
Depending on what you have ordered, the following is set:
– Configured valve terminal with additional supply
(order code AZ):
Factory setting: Load voltage supply via separate load
voltage connection (1 ).
Connect the additional supply with a cable socket type
ASI-SD-FK... to the load voltage connection.
Valves can be switched off during EMERGENCY STOP.
– Configured valve terminal with additional supply
(order code AS):
Factory setting: Load voltage supply via AS-Interface
bus (3).
Sel the load voltage connection with a blanking plug
type ASI-SD-FK-BL (max. 0.3 Nm).
– Electric sub-base as individual part or spare part
(type CPV..-GE-ASI-4-Z):
Factory setting: Load voltage supply via separate load
voltage connection.
If necessary, configure the load voltage supply with
the DIP switch, see section 4.2.

4.3 Connecting the AS-Interface bus and the load voltage
Please note
The setting of a DIP switch determines the connection
via which the load voltage supply for the outputs (valve
solenoid coils) is provided, see section 4.2.
‒ via the load voltage connection,
‒ via the AS-Interface bus.
Note the following when converting the valve terminal:
SSwitch on the power supply only if the DIP switch is
positioned at a permitted setting.
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-... 2017-11e English 11
Please note with branch lines:
– the maximum total 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 fluctuations in load voltage).
Pin assignment “Bus” (yellow cable):

2Pin 1: AS-Interface - (light blue)

*) Can be configured via DIP switch, see section 4.2.
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. If necessary, insert the cable socket or a blanking plug
and screw it tight (max. 0.3 Nm).
Seal open flat cable ends with the Fest 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.

4.5 Converting the valve terminal
The valve terminal can be fitted with double-solenoid
and/or single-solenoid valves. During conversion, the new
valve terminal configuration must be set with the DIP
switches on the bottom of the electric sub-base.
