At least one of the two LEDs L/A 1 and L/A 2 must be illuminated in green or be
illuminated in green and flash quickly in yellow. Depending on the data ex-
change, the flashing may be so fast that it appears that the LED is illuminated.
The color then appears to be light green.
If the diagnostic run is successful, you may commission the valve system. Other-
wise, the errors must be remedied, see section 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 status 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 different messages. See
ble 16.
Before commissioning and during operation, regularly check the bus coupler
u
functions by reading the LEDs.

12 Conversion of the Valve System

Danger of explosion caused by defective valve system in an explosive at-
mosphere!
g Ta-
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-
nents. See also the section
Up to 10 input and output modules 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.
The following figure shows an example configuration with valves and I/O mod-
ules. See g Fig. 15.
Depending on the configuration, your valve system may contain additional com-
ponents, such as pneumatic supply plates, electrical supply plates, or pressure
regulators. See section
