If the diagnostic run is successful, you may commission the valve system. Other-
wise, the errors must be remedied (see g 13. Troubleshooting).

11 LED Diagnosis on the Bus Coupler

The bus coupler monitors the power supplies for the electronic components and
actuator control. If they exceed or fall below a set threshold, an error signal will
be generated and reported to the controller. In addition, the state is displayed by
the diagnostic LEDs.
Reading the diagnostic display on the bus coupler
The LEDs on the top of the bus coupler report the messages listed in the table be-
low. See g Table 24.
Before commissioning and during operation, regularly check the bus coupler
u
functions.

12 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.

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-
Meaning
The electronics supply voltage is less than the
lower tolerance limit (18 V DC) and greater than
10 V DC.
The electronics supply voltage is less than
10 V DC.
The electronics supply voltage is significantly less
than 10 V DC (limit not defined).
Actuator voltage exceeds the lower tolerance
limit (21.6 V DC).
The actuator voltage is less than the lower toler-
ance limit (21.6 V DC) and greater than UA-OFF.
The actuator voltage is less than UA-OFF.
The configuration is OK and the backplane is
working perfectly.
The module was not configured correctly in the
controller (too few cyclic objects were mapped to
the PDOs).
Diagnostic message from module present.
Valve unit incorrectly configured or backplane
function error
Module in the OPERATIONAL (RUN) status
Simple Ethernet connection, no POWERLINK com-
munication
Communication error
For Gen.2 only:
Address is set to 0 or in the range of 240-255. This
range is invalid.
Communication aborted (module in STOP status)
Initialization of the Ethernet system
