1.4.4 Pneumatic supply plate
You can supply the valves with operating pressure separately
via the pneumatic supply plate. This is for example necessary
in the case of valve terminals equipped with several pressure
zones or when a large number of valves on the valve terminal
are switched simultaneously to flow.
Mounting of the pneumatic supply plate is described in
Chapter 5 under “Replace sub-base, supply plate or MPA-S
end plate”.
1.4.5 Electrical supply plate
You can separately supply the valves with load voltage via the
electrical supply plate.
The assembly of the electrical supply plate is described in the
VMPA-FB-SP-...-V-... assembly instructions.
1.4.6 Pressure zone separation
The MPA-S valve terminal can be equipped with pressure
zones.
The pressure zones are formed either by special sub-bases or
by special separating seals.
Separation of the pilot channels (12/14) and (82/84) is not
intended, as on the MPA-S valve terminal the pilot air supply
for pilot control of the valves is supplied centrally via the
corresponding electrical interface (pneumatic interface,
multiple connector plate, AS interface or CPI interface).
