5.3.6 Replacing electronics modules
Mounting of the electronics module to the proportional pressure regulator is described in
the assembly instructions VMPA-…TA-... .
The MPA-S valve terminal is equipped with one ele ctro nics module per sub-base. It provides the follow-
ing number of contacts between the electrical interlinking module and the solenoid coils, dependent on
the size of the sub-bases:
– for size MPA1 contacts for 4 v alve positions
– for size MPA2, contacts for 2 valve positions.
An integral part of the electronics module are the LEDs ( function section 4.5) and other electronic
components.
The electronics module may be damaged if it is handled incorrectly.
• Switch off the power supply be fore removing the electronics modules.
• Donottouchanycomponents.
• Observe the handling specifications for electrostatically sensitive devices.
• Discharge yourself before assembling or disassembling modules to protect the mod-
ules from discharges of static electricity.
Caution
• Replace an electronics module only by an electronics module of t he same type.
There are different designs of the electronics module, dependent on the alternative c onnection.
Electronics modules for the MPA-S valve terminal with CPX terminal
Caution
Damage to components and operative malfunctions!
It is not permissible to supply voltage to MPA pneumatic modules that are equipped
with electronics modules and have a c ommon circuit via interlinking blocks of type
CPX-GE-EV-V... (valve feed) or 5-pin system feed ( type CPX-GE-EV-S-7/8-5POL).
• If your MPA-S pneumatics are equipped with electronics modules of type
VMPA1-FB-E MS-orVMPA2-FB-EMS-, you must supply power to the MPA-S
pneumatics exclusively via a four-pin system supply module of type CPX-GE-EV-S
or CPX-GE-EV-S-7/8-4POL of the CPX terminal.
Observe the summary in Tab. 5.2.
