2.1.2 Address assignment of the CPV Direct
The CPV Direct always occupies 16 output addresses,
irrespective of the number of valve solenoid coils fitted on it.
This enables the CPV Direct to be extended at a later stage
without the need to shift the addresses.
The following diagram shows the addressing sequence of the
individual CPV valve plates.

Fig.2/1: Address assignment of the CPV Direct
A valve location on the CPV Direct always occupies 2 ad
dresses, even if it is fitted with a blanking plate or pressure−
separator plate. If a valve location is fitted with a double−
solenoid valve, the following applies:
pilot solenoid coil 14 occupies the less significant
address
pilot solenoid coil 12 occupies the more significant
address.
With single−solenoid valves the higher−value address
remains unused.
