2 Function and application

Valve sub-base type CPE...-PRSG-2/-3 (double or three-way) connects 5/2 or

5/3-way valves of type CPE-... with central supply connections.
Two further valves can be supplied by means of extension plate type CPE...-PRS-2.

Different pressure zones or a bilateral pressure supply can be implemented by
means of end plate type CPE-...-PRS-EP. The maximum amount of equipment
which can be fitted is:

6 valves

– with compressed air supply on one side

or

– for each pressure zone

Fig. 2

The diaphragms have been removed from the variants CPE-...-PRSO-...

Valve sub-base CPE-...-PRS... is intended for mounting on a wall or on a hat rail.

3 Safety conditions

Note

Incorrect handling can lead to malfunctioning.
For correct and safe use of the product:
S Compare the specified limit values with your current application.

The permissible limit values, e.g. for pressures and temperatures, must not
be exceeded.

12 valves

– with compressed air supply on two

sides

S Also observe the regulations of the trade association, the German Technical

Control Board (TÜV), the VDE and relevant national regulations.

S Remove all packing material such as protective wax, foils, caps and cartons.

The individual materials can be disposed of in separate containers for recycling
purposes.

S Unauthorized product modification is not permitted.

mechanical

Preparation

S First place all CPE...-PRS... in their mount

ing sequence.

S Carry out the pressurization of the valves

(e.g. by first drawing a sketch).

If several pressure zones are used,

Fig. 3

Note

S Make sure that the diaphragms are not broken at the interface of two pres

sure zones. Damaged diaphragms cannot be sealed again.

You must decide here, whether diaphragms should be removed from the
compressed air channels in order to provide an unhindered flow.

Removing non-required diaphragms

A

S Proceed as follows

– Press the three diaphragms in the

compressed air channels on the
CPE...-PRS... inwards with a punch

(A) as shown in the sketch
– Deburr any broken edges
– Remove shavings

Due to this time-saving work mode, ir
regular edges occur compared with preci
sion processing by machine.

For hat rail fitting

1. Hang all the CPE-...-PRS... onto the hat rail in the correct sequence.

2. Press the CPE-...-PRS... onto the rail until the fastening slides 5 clip into

place.

In order to link the CPE...-PRS...:

1. Place one sealing ring each between the
three compressed air channels and press
the manifold blocks together (è Fig. 5).

2. Push one connector on both sides 1
onto the self-formed rail until it engages
(è Fig. 6).

Fig. 5

In order to fit the CPE valves (Fig. 7):

1. Press in all the valve slides 2 until they
snap into the first notch.

2. Push a seal onto each compresssed air
output.

3. Screw the valve connectors with the seals

fitted into connections 3 and 5 of the CPE
valve.

4. Place CPE valves onto the manifold block
(observe protection against torsion 4 ),
press it on and simultaneously insert
valve slides into the 2nd detent.
Valveslide and valve are then flush against
each other.

Fig. 7

Warning

Only in this way can you prevent non-secured valves from being pushed out
when the sub-base is pressurized.

Carrying out the fitting

S Make sure that the linked CPE...-PRS... are fitted free of distortion.

S Leave sufficient space for the connections.

Fastening onto a hat rail

S Tighten the locking screws of the

CPE...-PRS... to the hat rail.

Fastening onto a wall

S Insert the following number of screws for

fastening:

Pneumatic

S Use preferably round connectors of type QS..-... with cylindrical connecting

thread.

S Connect the pneumatic tubing in accordance with the pressurization sketch

(compare with Fig. 3).
The connecting threads must be sealed (torques è Technical data).

If using cone-shaped QS..-... plug connectors:

Warning

S Make sure that the connecting threads

are not screwed in fully.

Otherwise the thread will be damaged.

Fig. 11

S Screw the connectors into the ports with two layers of sealing tape as follows:

– at first by hand
– then two turns more with a suitable tool.

For closing non-required valve locations:

S Use blind plates 3 (see Fig. 1) of type CPE-...-PRSB.

5 Maintenance and care

S Clean the CPE...-PRS... when required with the cleaning agents specified.

– water or soap suds (max. 60 °C)
– petroleum ether (free of aromatic compounds).

6 Dismantling and repairs

In order to dismantle the CPE valves:

S Exhaust the CPE...-PRS...

S Pull the valve slide 2 outwards one notch.

Observe here the minimum distance between the valve slide and the mounting
surface of the connector 1.

In order to dismantle linked CPE...-PRS...:

1. Remove the CPE valves.

2. Press down the locking nose 5 and pull the valve slide completely away from

the sub-base.

3. Dismantle the individual parts in the reverse order to fitting.

Dismantling from a hat rail

1. Remove the CPE valves.

2. Loosen the locking screws.

3. Dismantle linked CPE...-PRS-... .
