– Right end plate
– Soft start valve
The following components can be used for additional power supplies:

Tab. 4 Types of pilot air supply
Functional failure or malfunctions due to faulty pilot air supply
• Supply each pressure zone with working pressure and pilot pressure. Do not form pressure-free
zones è 5.1.1.4 Creation of pressure zones.
• Use only one supply component for the pilot air supply in each pressure zone.
• Observe the critical limits of the pilot pressure è 10.3 Technical data, pneumatic.
5.1.1.3 Pilot exhaust air
– Unducted pilot exhaust air: the pilot exhaust air is exhausted directly at each valve. If a soft start
valve or pilot air valve is used, the pilot exhaust air can only be exhausted in an unducted manner.
– Ducted pilot exhaust air: the pilot exhaust air is exhausted at the port(12) on the right end plate.

5.1.1.4 Creation of pressure zones
In order to supply valves with different pressures, pressure zones for the working air and the pilot air
can be formed within the valve terminal. The pressure zones are limited by separating seals between
the manifold sub-bases è 5.2.1.1.5. Separating seals for pressure zone formation.
Each pressure zone must be supplied with compressed air via a supplying component. Pressure-free
zones must not be created.
Pressure zones are essential in order to operate vacuum or low-pressure-compatible valves with other
valves.
5.1.2 Electrical functions
5.1.2.1 Formation of voltage zones
With the CPX terminal and the pneumatic interfaces, voltage zones can be formed in the pneumatic
part of the valve terminal.
The 24 V power supply to the valves is provided via the load voltage supply valves of the CPX terminal
(Uval).
The power for the pressure switches and the vacuum generators is supplied by the electronic power
supply (UEL/SEN). After switching off the load voltage supply, the pressure switches continue to be sup-
plied with voltage for the valves of the CPX terminal (Uval).
Further information on the power supply of the CPX terminal èDescription of the CPX system (CPX-
SYS-...).
