Note
Replacing a CPI/CP module with a CPI/CP module of a
different type or replacing several CPI/CP modules will
require new commissioning and new saving of the string
assignment (see section 1.7).
In order to replace a single CP module, proceed as follows:
1. Switch off the power supply for the CPV Direct.
2. In the case of CPI/CP output modules and valve terminals
on the CP string concerned:
switch off the following sources of energy:
the compressed air supply to the valve terminal
the operating voltage supply for the CPI/CP output
module.
3. Disconnect all connecting cables and, if necessary, also
the tubing.
4. Connect all the cables and, if applicable, the tubing with
the new module of the same type.
5. Now connect the new module of the same type to the
same string.
6. In the case of CPI/CP output modules and CP valve
terminals:
switch on the operating voltage supply or the compressed
air supply again.
7. Switch on the power supply for the CPV Direct again.
8. Check the addresses of the CPI system.
