– If a valve position is equipped with a valve which has two
pilot solenoids, the following assignment applies:
– Pilot solenoid 14 occupies the less significant ad-
dress.
– Pilot solenoid 12 occupies the higher-value address.
– In the event of valves with only one pilot solenoid, the
higher-value address remains unused.
– Addresses are therefore assigned on the CDVI valve
terminal from left to right, however from right (14) to
left (12) on the individual valve terminals.
