Tab. 5 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.• Required pilot pressure at port (12/14) è 13.3 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.

Convert to ducted pilot exhaust air è 11.2.3 Convert to ducted pilot exhaust air.

5.1.1.4 Creation of Pressure ZonesIn order to supply valves with different pressures, pressure zones for the working air and the pilot aircan be formed within the valve terminal. The pressure zones are limited by separating seals betweenthe manifold sub-bases è 5.2.1.12 Separating seals for pressure zone formation.Each pressure zone must be supplied with compressed air via a supplying component è Fig.2. Pres-sure-free zones must not be created.Several pressure zones are required within the valve terminal to operate vacuum or low-pressure-com-patible valves with other valves.

Product overview


Use of Soft Start ValvesIn a pressure zone, a soft start valve must not be combined with another supplying component forduct (1).When using several soft start valves, observe the electrical regulations for creating voltage zonesè 5.1.2.1 Formation of Voltage Zones.

5.1.2 Electrical Functions

5.1.2.1 Formation of Voltage ZonesWith the CPX terminal and the pneumatic interfaces, voltage zones can be formed in the pneumaticpart of the valve terminal.

Product overview


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 powersupply (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-...).

Depending on the pneumatic interface variant, up to 3 safe voltage zones can be formed in the pneu-matic part of the valve terminal. The voltage zones can be switched off independently of each otherand in an electrically safe manner. A total of up to 24 addresses can be controlled via the pneumaticinterface.

start valve – exhausting the working pressure– Exhausting the pilot pressure– Query of the exhausted state with a pressure switch in the pilot control

The switching signal of the pressure switch is sent to the CPX terminal.

Fig. 15 Operating pressure of the soft start valve as a function of the number of valves

The times depend on the volume to be filled (configuration of the valve terminal).The switch-on process takes place in 2 stages:– Duct (1) of the valve terminal is pressurised.

The pressurisation time t4 can be adjusted with the flow control screw 4.If the soft start valve is used for the pilot air supply, duct (14) is immediately supplied with the fulloperating pressure.

– When the working pressure in duct (1) reaches half the operating pressure, the soft start valvereleases the full flow rate.

Switching off/exhaustingIf the supply voltage is switched off or the output is switched off via the control, the soft start valveblocks the compressed air supply. Duct (1) is exhausted via the soft start valve.If the soft start valve is used for the pilot air supply, an additional duct (14) is exhausted via the softstart valve.

8 Installation

8.1 Installation Pneumatics

8.1.1 Compressed Air Preparation

8.1.1.1 Operation with unlubricated compressed airUnfiltered compressed air will reduce the service life of the valve terminal.An excess of residual oil content in the compressed air will cause valves to malfunction, and will causethe life-time lubrication necessary for unlubricated operation to be washed out.• Maintain the residual oil content

– Organic oils (oils based on synthetic or native esters, e.g. rapeseed oil methyl ester): maxim-um residual oil content 0.1 mg/m3 ISO 8573-1:2010 [–:–:2]

– Mineral oils (e.g. HLP oils to DIN 51524 Parts 1 to 3) or oils based on polyalphaolefins (PAO):maximum residual oil content 5 mg/m3 ISO 8573-1:2010 [–:–:4]

Tab. 29 Pressure rise in the overall supply

The pressure increase of the total supply and the movement of the actuator depend on the supplyingcomponent.The pressure rise of the pilot air in duct (14) is independent of the supplying component. Dependingon the valve function, the working valves move immediately to the set switching position.

8.1.1.3 Preventing back pressureWhen exhausting large-volume actuators or if the exhaust performance is too low, back pressure maybuild up in the valve terminal's exhaust ducts. This back pressure can lead to pneumatic actuation ofother valves, especially with unswitched 3/2-way valves that are normally closed.

Installation


1. Optimise pressurisation and exhaust performance of the valve terminal, e.g. with the followingmeasures:– larger tubing diameters– additional pressure feed via pneumatic supply plates– Exhausting via pneumatic supply plates with silencer or exhaust plate– Separate è 11.2.1 Converting to Multiple Pressure Zonesexhaust air ducts by pressure zones

.2. Install check valves in common exhaust lines.

8.1.1.4 Check prerequisites for vacuum or low pressure operation (valves with Identcode VV)Before connecting valves with Identcode VV, check the requirements for vacuum or low-pressureoperation:– Supply operating pressure for the pneumatic springs at port (1).– Supply vacuum to port (5) and operating pressure to port (3) or vacuum to port (3) and operating

pressure to port (5).– To enable the ejector pulse during vacuum operation, establish a connection between the suction

line and the pressure supply line with a T-piece.

8.1.2 Connecting Pneumatic LinesObserve the following points when connecting the pneumatic lines:– For external pilot air supply, you only need to supply the pilot air at port (14).– If the internal pilot air supply (duct 14) is via a soft start valve or pilot air valve, do not connect an

additional pilot air supply.1. Mount the seals.2. Mount screw connections or silencers.3. Mount the tubing.

8.2 Electrical Installation

8.2.1 Connecting electrical cables

• Connect power supplyè Description of the CPX system (CPX-SYS-...).• Connect CPX modules è Descriptions of the CPX modules.• Long signal lines reduce the immunity to interference.

– Observe the maximum permissible signal cable length of 30 m.

8.2.1.1 Switch on the power supply

WARNING!

Risk of injury due to electric shock.• For the electrical power supply with extra-low voltages, use only PELV circuits that guarantee a

reliable separation from the mains network.• Observe IEC 60204-1/EN 60204-1.

The power supply to the valves is provided via the load voltage supply valves of the CPX terminal(UVAL).The power supply for the pressure switches and the vacuum generators is provided by the operatingpower supply (UEL/SEN). After switching off the load voltage supply, the pressure switches continue tobe supplied with voltage for the valves of the CPX terminal (UVAL).

Tab. 54 Required Components for Valve Position Extension

If a manifold sub-base is added, the address assignment of all valves to the right of the added mani-fold sub-base changes.

Disassembly1. Remove valve terminal from the mounting surface.2. Remove the manifold sub-base or pneumatic supply plate at the point at which the valve terminal

is extended è Disassembly.

Assembly1. Mount additional manifold sub-base and, if necessary, an additional pneumatic supply plateè Assembly.

2. Mount components– Vertical stacking components è Assembly– Valves or cover plates è Assembly
