9 LED Diagnosis on the IO-Link Interface

The IO-Link interface monitors the supply voltages for the electronics compo-
nents and valve control. If the values fall below a set limit, an event is generated
and reported to the IO-Link master. In addition, the status is displayed by the di-
agnostic LED.
Reading the diagnostic display on the IO-Link interface
The LEDs on the top side of the IO-Link interface report the messages listed in Ta-
ble 9.
Before commissioning and during operation, regularly check IO-Link interface
u
functions by reading the LEDs.

10 Conversion of the Valve System

Danger of explosion caused by defective valve system in an explosive at-
mosphere!
Malfunctions may occur after the configuration or conversion of the valve sys-
tem.
After configuring or converting a system, always perform a function test in
u
a non-explosive atmosphere before recommissioning.
This chapter describes the structure of the complete valve system, the rules for
converting the valve system, the documentation of the conversion, as well as the
re-configuration of the valve system.
The assembly of the components and the complete unit is described in
the respective assembly instructions. All necessary assembly instruc-
tions are included as printed documentation on delivery and can also
be found on the CD R412018133.

Meaning
The electronics and valve supply voltage is greater
than the lower tolerance limit (21.6 V DC). The
communication connection to the IO-Link master
is in the ONLINE operating state and IO-Link com-
munication has been started.
The electronics and valve supply voltage is greater
than the lower tolerance limit (21.6 V DC). The
communication connection to the IO-Link master
is in the OFFLINE operating state or IO-Link com-
munication has not been started.
on. The communication connection to the IO-Link
master is OFFLINE or the IO-Link communication
has not been started.
on. The communication connection to the IO-Link
master is ONLINE and IO-Link communication has
been started.
The supply voltage to the valves is not switched
on. The IO-Link interface is not connected to the
master.
DANGER
The extension circuit boards of a valve system use length-optimized
boards according to the configuration.
Subsequent shortening is not possible. If necessary, the base plate
area has to be replaced by extension base plates after the 2nd valve
position.

10.1 Valve system

The IO-Link interface valve system can be extended by up to a permissible maxi-
mum of 24 solenoid coils.

10.2 Valve zone

The following figures show the components as illustrations and sym-
bols. The symbol representations are used in the section "Conversion
of the valve zone".

10.2.1 Base plates

The valves from the AV series are always mounted on base plates that are assem-
bled into blocks so that the supply pressure is applied to all valves.
The base plates are always 2x or 3x base plates for two or three single or double
solenoid valves. The first base plate for minimal configuration of the IO-Link inter-
face is always a 2x base plate. Base plate extension kits always include the corre-
sponding multipole board.

10.2.2 Pneumatic supply plates and AV03-AV05 combination plates

Pneumatic supply (6) and combination plates can be used to divide the valve sys-
tem into sections with different pressure zones
Supply and combination plate extension kits always include the corresponding
multipole board.
