26 . Pneumatic interfaces MPA pneumatics From the technical point of view, the individual MPA pneu matic modules each represent an electric module with e.g. 8 digital outputs for controlling the valves fitted (see chapter ). Please note The pneumatic interface for MPA pneumatics provides the mechanical and electrical connection to the MPA pneu matic modules. As regards the CPX terminal, this pneumatic interface does not therefore count as an electric module. Midi/Maxi pneumatics, CPA pneumatics or VTSA pneumatics From the technical point of view, the pneumatic interfaces for Midi/Maxi pneumatics, CPA pneumatics or VTSA pneu matics (ISO) each represent an electric module with a vari able (configurable) number of digital outputs for controlling the valves fitted (see following sections).

30 . Pneumatic interfaces. 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. Before carrying out installation and maintenance work, switch off the following: the compressed air supply the operating and load voltage supplies. 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 system manual. Instructions on extending or converting the pneumatic modules can be found in the appropriate pneumatics manual. For Midi/Maxi, CPA or ISO pneumatic interfaces: The setting of the DIL switches for configuring the pneumatics (valves used) can be set on the CPX terminal without the need to disamantle the terminal. 8

31 . Pneumatic interfaces. Settings for configuring the pneumatics Midi/Maxi, CPA or VTSA pneumatics Settings for configuring the pneumatics are only necessary with the pneumatic interfaces for Midi/Maxi, CPA and VTSA 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 customer 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. Warning Sudden unexpected movement of the connected actuators and uncontrolled movements of loose tubing can cause injury to human beings or damage to property. Before carrying out installation and maintenance work, switch off the following: the compressed air supply the operating and load voltage supplies. 9

32 . Pneumatic interfaces 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 screws 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 (IP6). 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 0 fitting/removal cycles. Removing the cover. Loosen the screws in the cover with a TORX screwdriver size T0.. Lift the cover up carefully. 0

33 . Pneumatic interfaces. Set the DIL switch elements in accordance with the follow ing table. Use a suitable tool, e.g. a small screwdriver, for setting the DIL switches. Printed circuit board Fault LED DIL switches for configuring the pneumatics Fig. /: DIL switches on the pneumatic interface (here for CPA pneumatics) The DIL switch contains 8 switch elements. These switch elements are numbered from...8. The positions OPEN (CPA, VTSA/ISO) or ON (Midi/Maxi) are marked. Rules for setting If the number of valve solenoid coils fitted is less than the number of output addresses set with the DIL switch, the superfluous addresses will be reserved for later exten sions (if the maximum number of valves is fitted, output addresses will then remain unused). Modifications to the configuration will not become effective until the operating voltage is switched on again. 8 further output addresses per switch element will be assigned for valves in the address range. The setting of the highest value DIL switch in the ON (closed) position is decisive for the assigned address range.

Instructions on installing the electric components can be found in the CPX system manual. Instructions on addressing the valve solenoid coils as well as further instructions on installing the electric components can be found in the relevant field bus node manual. Power supply The V supply for the valves is provided via the load voltage for the valves of the CPX terminal (V VAL ). The power supply for the electronics of the pneumatic inter faces is provided via the operating voltage supply for the electronics/sensors (V EL/SEN ). Address assignment within the pneumatic modules Instructions on assigning the addresses to the individual valve solenoid coils with Midi/Maxi or CPA pneumatics can be found in the appropriate pneumatics manual. Instructions on assigning the addresses to the individual valve solenoid coils with MPA pneumatic modules can be found in chapter. Protection class When completely fitted, the pneumatic interfaces with the valve terminal pneumatics comply with protection class IP6 (see appendix A.).

37 . Pneumatic interfaces. Instructions on commissioning 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 individual MPA pneumatic modules (module orientated, see chapter ). Further information on parametrizing can be found in the system manual or in the manual for the field bus node. Please note Activate the wire fracture monitoring only for outputs which also have a valve solenoid coil. If the wire fracture monitoring is activated for an output which does not have a valve solenoid coil, the CPX terminal will register the fault Wire fracture" when it is switched on, due to the valve solenoid coil being incorrectly regis tered as defective.

53 . MPA pneumatic modules. 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. Before carrying out installation and maintenance work, switch off the following: the compressed air supply the operating and load voltage supplies. 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 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 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. 7

54 . 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 screws 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 (IP6). Connecting surfaces must be clean (to ensure sealing effect, avoid leakage and contact faults). Dismantling the electronic module. Use a screwdriver with a narrow blade to loosen the fastening screws of all valve or blanking plates and remove the plates from the sub bases.. Loosen the screws with which the electronic module is fastened to the sub base.. Pull the electronic module upwards out of the body of the sub base. 8

56 . MPA pneumatic modules Fitting the electronic module Caution Replace an electronic module only by an electronic module of the same type (see section.). Please note Before fitting, check the condition and position of the following seals: the sealing lip of the electronic module the ring seal of the electrical contacts the flat seal of the valve plates or blanking plates.. Place the electronic module in the sub base.. Tighten the screws of the electronic module with Nm.. Then fit the valve plates or blanking plates. Check the seals of the valve or blanking plates for damage. Replace seals if they are damaged.. Make sure that the seals are seated correctly. The flat seal between the sub base and the component must be seated in the recess in the component. The ring seals between the electronic module and the component are conical. The ring seals must be fitted on the guide pins of the components so that the cone slides easily into the appropriate recess in the electronic module (see Fig. /).. Place the components on the sub base. 6. Screw the components at first only slightly and then tighten with Nm. 0

57 . MPA pneumatic modules. Installation Instructions on installing the pneumatic components can be found in the Pneumatics Manual type P.BE MPA... Instructions on installing the electric components can be found in the CPX System Manual. Instructions on addressing the valve solenoid coils as well as further instructions on installing the electric components can be found in the relevant field bus node manual. Power supply The V supply for the valves is provided via the load voltage for the valves of the CPX terminal (V VAL ). The power supply for the electronic modules is provided via the operating voltage supply for the electronics/sensors (V EL/SEN ). Caution Damage to components and functional damage! It is not permitted to supply voltage to MPA pneumatic modules with electronic modules without electrical isola tion via a manifold sub base type CPX GE EV V... (valve supply) or CPX GE EV S 7/8 POL ( pin system supply). If your MPA pneumatics are fitted with electronic mod ules of type VMPA FB EMS... or VMPA FB EMS..., you must supply the MPA pneumatics exclusively via a pin system supply module type CPX GE EV S or CPX GE EV S 7/8 POL. Note the overview in Tab. /.

Tab. /: Permitted supply modules modules for MPA electronic modules In the case of MPA electronic modules with electrical isolation type VMPA FB EMG... or VMPA FB EMG..., V EL/SEN and V VAL are completely electrically isolated. In conjunction with the following voltage supply modules, it is therefore possible to switch off the valve supply voltage at all poles: Manifold sub base with valve supply type CPX GE EV V... (M8 or 7/8") 7/8" manifold sub base with pin system supply module type CPX GE EV S 7/8 POL Intermediate electrical supply module (supply plate (electric) type VMPA FB SP... V...)
