12.5.4 Reviewing the valve zone conversion

Following the conversion of the valve zone, use the following checklist to de-
u
termine whether you have complied with all rules.
• Have you mounted at least 4 valve positions after the first pneumatic supply
plate?
• Have you mounted a maximum of 64 valve positions?
• Have you integrated no more than 32 electrical components? Note that an
AV-EP pressure regulator corresponds to three electrical components.
• Have you mounted at least two valves after every pneumatic or electrical sup-
ply plate that marks the start of a new section?
• Have you always installed the valve driver boards to be in line with the base
plate limits, i.e.
- One base plate, 2x, is installed with one valve driver board, 2x,
- Two base plates, 2x, are installed with one valve driver board, 4x,
- One base plate, 3x, is installed with one valve driver board, 3x?
• Have you integrated no more than 8 AV-EPs?
If you have answered "Yes" to all these questions, you may proceed with the doc-
umentation and configuration of the valve system.

12.5.5 Conversion documentation

PLC configuration key
After a conversion, the PLC configuration key printed on the right end plate is no
longer valid.
1. Correct the PLC configuration key or cover it with a new label and write the
new PLC configuration key on the end plate.
2. Always document all changes to your configuration.

Material number

After a conversion, the material number (MNR) on the right end plate is no longer
valid.
Mark the material number so that it is clearly visible that the unit no longer
u
corresponds to its original condition on delivery.

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.
In the PLC configuration software, adapt the number of input and output ob-
u
jects to the valve system.
Because the data is mapped to the PDO in physical sequence, the position of the
data in the PDO will shift if an additional module is used. However, if you add a
module at the left end of the I/O modules, with an output module nothing will be
shifted. Only the object of the new module must be added. With an input mod-
ule, only the two diagnostic objects will be shifted by the newly added object.
After converting the valve system, always make sure the input and output ob-
u
jects are still correctly assigned.
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
u
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.
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.
2. Get an overview of the function of the product as related to the overall sys-
tem.
3. Try to clarify whether the product fulfilled the required function in the overall
system before the error occurred.
4. Try to detect all changes to the overall system in which the product is in-
stalled:
- Have the conditions or application for the product changed?
- Have changes (e.g. conversions) or repairs been made to the overall system
(machine/system, electrical, controller) or the product? If yes, which ones?
- Has the product or machine been operated as intended?
- What kind of malfunction has occurred?
5. Try to get a clear picture of the cause of the error. If necessary, ask the imme-
diate machine operator or foreman.

Check the polarization of the
power supply on the bus coupler
and the electrical supply plate.
