Please note
Do not connect the cables for the field bus when preparing
for commissioning.
You will thereby avoid:
addressing errors which may occur due to the modifica
tion of the address range during operation with various
field bus systems.
Proceed with preparation as follows:
1. Check the pneumatic tubing of the valve terminals with
the aid of the manual override (see pneumatics manual).
2. Check the complete electric circuitry of the CPX terminal.
3. Check the DIL switch settings of your CPX terminals (see
manual for the CPX field bus node).
