Contents and general instructions

Designated use

The CPX pneumatic interfaces, MPA pneumatic modules and CPX I/O modules described in this manual have been de signed exclusively for use in conjunction with CPX terminals from Festo. The pneumatic interfaces and I/O modules are only to be used as follows:

 as specified in industrial applicatio

without any modifications by the user

Only the conversions or modifications described in the documentation supplied with product are permitt

ed.

 in faultless technical condition.

If additional commercially−available components such as sensors and actuators are connected, the specified limits for

pressures, temperatures, electrical data, torques, etc. must not be exceeded. Please observe the standards specified in the relevant

chapters and

comply with technical regulations, as well as

with national and local regulations.

Warning

· In order to provide the electric power supply, use only

PELV circuits as per IEC/DIN EN 60204−1 (Protective Extra−Low Voltage, PELV ). Take int

o account also the general requirements for

PELV circuits as per IEC/DIN EN 60204−1.

· Use only power packs which guarantee reliable electri

cal isolation of the operating voltage as per IEC/DIN EN60204−1.

By the use of PELV power

units, protection against electric shock (protection against direct and indirect contact) is guaranteed in accordance with IEC/DIN EN 60204−1 (elec

trical equipment of machines, general requirements).

The CPX

terminal must first be dismantled before it can be extended or converted, or when a pneumatic interface must be replaced. Instructions

on this can be found in the CPX

Settings for configuring the pneumatics are only necessary with the pneumatic interfaces for Midi/Maxi, CP

pneumatics (ISO).

No settings are required for MPA pneumatics.

Caution

After conversion or extension of the Midi/Maxi, CPA or VTSA pneumatics, the number of output addresses occu

pied by the pneumatics must be

set on a DIL switch on the

pneumatic interface.

CPX terminals can be fitted with various valves and electric modules in accordance with the cus

tomer’s wishes.

The size of the valve address range on Midi/Max, CPA or VTSA pneumatics is not modified when the valves are ex tended or

converted, providing sufficient address space has already been reserved for the extension. The valve address range must be set with a DIL switch. The DIL switch is situ ated under the transparent cover on the pneumatic interface.

Caution

Modules may be damaged if they are not handled correctly.

· Do not touch the electrical contacts of the modules.

· Observe the regulations for handling electrostatically

sensitive components.

· Discharge yourself electrostatically before fitting or re

moving components in order to protect the components against discharges of static electricity.

Please note

Handle all modules and components of the CPX terminal with great care. Please note especially the following:

· Screws must be fitted accurately (otherwise threads will

be damaged). Screws must be fastened at first only by hand. Place the scre

ws so that the self−cutting threads are used.

· The specified torques must be observed.

· Screw connections must be fitted free of offset and

mechanical tension.

· Check the seals for damage (IP65).

· Connecting surfaces must be clean (to ensure sealing

effect, avoid leakage and contact faults).

The screw connection between the cover and the lower part of the CPA pneumatic interface is designed for at least

10 fitting/removal cycles.

Midi/Maxi, CPA or VTSA pneumatics

The reaction of the pneumatic interface for Midi/Maxi, CPA or VTSA pneumatics can be parametrized.

The table below gives an overview of the parameters for the pneumatic interfaces.

With the MPA pneumatics, parametrizing takes place via the indi

vidual MPA pneumatic modules (module−orientated, see

chapter 2).

Further information on parametrizing can be found in the

system manual or in th

e manual for the field bus node.

Please note

If the wire−fracture monitoring is act

ivated for an output

which does not have a valve solenoid coil, the CPX terminal will register the fault Wire fracture" when it is swi

Contents of this chapterThis chapter describes the MPA pneumatic modules for CPX

terminals.

In a CPX terminal the MPA pneumatic modules provide d outputs for the valves fitted (valve solenoid coils) and are adapted to the specific application by means of different

valve plates.

You should

read this chapter if your CPX terminal is fitted with

MPA pneumatics.

Further information Information on fitting the complete CPX terminal, connec

the power supply as well as general instructions on configur ation and parametrizing can be found in the CPX system man ual.

Informatio

n on the pneumatics of the CPX terminal, especially on the available valve plates, can be found in the appropriate pneumatics manual.

Information on

the address assignment as well as on commis sioning can be found in the appropriate field bus node man ual or function module manual.

2.2 Fitting

Warning

Sudden unexpected movement of the connected actuators and uncontrolled movements of loose tubing can cause injury to human beings or damage to property.

Befo

re carrying out installation and maintenance work,

switch off the following:

the compressed air supply the operating and load voltage supplies.

The CPX te

rminal must first be dismantled before it can be extended or converted, or when a pneumatic interface must be replaced. Instructions o

n this can be found in the CPX sys

tem manual.

Instructions on extending or converting the MPA pneumatic modules can be found in the appropriate

pneumatics manual.

Electronic modules or valve plates can be replaced on the fitted CPX terminal.

Caution

Modules may be damaged if they are not handled correctly.

· Do not therefore touch the contacts of the components.

· Observe the regulations for handling electrostatically

sensitive components.

· Discharge yourself electrostatically before fitting or re

moving components in order to protect the components against discharges of static electricity.

2. MPA pneumatic modules

Please note

Handle all modules and components of the CPX terminal with great care. Please note especially the following:

· Screws must be fitted accurately (otherwise threads will

be damaged). Screws must be fastened at first only by hand. Place the

screw

s so that the self−cutting threads are used.

· The specified torques must be observed.

· Screw connections must be fitted free of offset and

mechanical tension.

· Check the seals for damage (IP65).

· Connecting surfaces must be clean (sealing effect, avoid

leakage and contact faults).

Dismantling the electronic module

1. Use a screwdriver with a narrow blade to loosen the fastening screws of all valve or blanking plates and re move the plates from the

sub−bases.
