12.6 Conversion of the I/O zone

12.6.1 Permissible configurations

No more than ten I/O modules may be connected to the bus coupler.
For further information on converting the I/O zone, see the system descriptions
of the individual I/O modules.
We recommend an expansion of the I/O modules starting from the left
end of the valve system.

12.6.2 Conversion documentation

The PLC configuration key is printed on the top of the I/O modules.
Always document all changes to your configuration.

12.7 New PLC configuration for the valve system

Configuration error!
An incorrect valve system configuration can cause malfunctions in and dam-
age to the overall system.
1. The configuration may therefore only be carried out by an electrical special-
ist!
2. Observe the specifications of the system owner as well as any restrictions
resulting from the overall system.
3. Observe the documentation of your configuration program.
After converting the valve system, you need to configure the newly added com-
ponents. Components that are still in their original slots will be detected and do
not require a new configuration.
If you have exchanged components without changing their order, you
do not need to reconfigure the valve system. All components will be
recognized by the controller.
For the PLC configuration, proceed as described in section g 5. PLC Configu-
u
ration of the AV Valve System.

13 Troubleshooting

13.1 Proceed as follows for troubleshooting

1. Even if you are in a rush, proceed systematically and in a targeted manner.
2. In the worst case, arbitrary, indiscriminate disassembly and modifications to
the settings may mean that you are no longer able to determine the original
cause of the error.
3. Get an overview of the function of the product as related to the overall sys-
tem.
4. Try to clarify whether the product fulfilled the required function in the overall
system before the error occurred.
5. Try to record any changes to the overall system where the product is installed:
- Have changes been made to the operating conditions or area of application
of the product?
- Have changes (e.g. conversions) or repairs been made to the overall system
(machine/system, electrical system, controller) or the product? If so: What are
they?
- Has the product or machine been operated as intended?
- How does the malfunction manifest itself?
6. Try to get a clear picture of the cause of the error. If necessary, ask the imme-
diate machine operator or foreman.

There is no module con-
nected to the bus coupler.
IO/DIAG LED flashes red
There is no end plate present. Connect an end plate.
More than 32 electrical com-
ponents are connected on
the valve side, see section
g 12.5.3. Impermissible con-
figurations.
Over ten modules are con-
nected in the I/O zone.
The module circuit boards are
not plugged together cor-
rectly.
A module circuit board is de-
fective.
The bus coupler is defective.
Remedy
Connect the power supply at
plug X1S on the bus coupler
and to the electrical supply
plate.
Check the polarization of the
power supply on the bus cou-
pler and the electrical supply
plate.
Switch on system component
Stipulate a set point
Connect the supply pressure
Increase the supply pressure
Check LEDs UA and UL on the
bus coupler and the electrical
supply plate and supply the
devices with the correct (ade-
quate) voltage.
Check the pressure line con-
nections and tighten, if nec-
essary
Properly connect the pneu-
matics for the pressure lines
Perform the following four
steps:
1. Disconnect the bus coupler
from the voltage and set an
address between 1 and 254
(0x01 and 0xFE).
2. Connect the bus coupler to
the voltage and wait 5 sec-
onds, then disconnect the
voltage again.
3. Set the address switch to
0x00.
4. Re-connect the bus coupler
to the voltage.
The name should now be
deleted, see section
g 9.2. Changing the name.
Check the power supply at
plug X1S.
Adjust the configuration.
Check modules.
Connect a module.
Reduce the number of electri-
cal components on the valve
side to 32.
Reduce the number of mod-
ules in the I/O zone to ten.
Check the plug contacts of all
modules
(I/O modules, bus coupler,
valve drivers, and end plates)
Exchange the defective mod-
ule.
Exchange the bus coupler.
