Designa-
tion
Color State Meaning
UL (14) Green Illumi-
nated
The electronics supply voltage is greater than the
lower tolerance limit (18VDC).
Red Flashes The electronics supply voltage is less than the lower
tolerance limit (18VDC) and greater than 10VDC.
Red Illumi-
nated
The electronics supply voltage is less than 10VDC.
Green/red Off The electronics supply voltage is significantly less than
10VDC (limit not defined).
UA (15) Green Illumi-
nated
Actuator voltage exceeds the lower tolerance limit
(21.6VDC).
Red Flashes The actuator voltage is less than the lower tolerance
limit (21.6VDC) and greater than UA-OFF.
Red Illumi-
nated
The actuator voltage is less than UA-OFF.
MOD (16) Green Illumi-
nated
The configuration is OK and the backplane is working
perfectly.
Green Flashes The module has not yet been configured
(there is no connection to a master).
Red Flashes Diagnostic message from module present
Red Illumi-
nated
Valve unit incorrectly configured or backplane func-
tion error
NET (17) Green Illumi-
nated
The bus coupler exchanges cyclical data with the con-
troller.
Green Flashes Waiting to establish communication with the con-
troller
Red Flashes Communication was disrupted (no communication
with the master)
Red Illumi-
nated
Severe network problems, IP address assigned twice
Green/red Off An IP address has not yet been assigned and the DHCP
service is off.
L/A 1 (18) Green Illumi-
nated
The physical connection between the bus coupler and
network has been detected (link established).
Yellow Flashes
quickly
Data packets received (flashes for each data packet re-
ceived)
Green/ yel-
low
Off The bus coupler does not have a physical connection
with the network.
L/A 2 (19) Green Illumi-
nated
The physical connection between the bus coupler and
network has been detected (link established).
Yellow Flashes
quickly
Data packets received (flashes for each data packet re-
ceived)
Green/ yel-
low
Off The bus coupler does not have a physical connection
with the network.
12 Conversion of the Valve System
DANGER
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.
u After configuring or converting a system, always perform a function test in
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.
12.1 Valve System
The AVseries valve system consists of a central bus coupler that can be extended
towards the right to up to 64valves and up to 32 associated electrical compo-
nents g12.5.3.Impermissible configurations. Up to 10 input and output mod-
ules can be connected on the left side. The unit can also be operated without
pneumatic components, i.e. with only a bus coupler and I/Omodules, as a stand-
alone system.
Fig.6 shows an example configuration with valves and I/O modules. Depending
on the configuration, your valve system may contain additional components,
such as pneumatic supply plates, electrical supply plates, or pressure regulators

12.2 Valve Zone
The following figures show the components as illustrations and sym-
bols. The symbol representations are used in section g12.5.Conver-
sion of the Valve Zone.
12.2.1 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.
