3.3.2 MPA-S valve terminal with pressure zone separation
Note
•
Operate the valves with ident. code I (2x2/2-way valve)
in a separate pressure zone with separate exhaust
channel (5) if the MPA-S valve terminal is also equipped
with other valves.
Note the following in the case of the MPA-S valve terminals
which are operated with internal pilot air and which have
several pressure zones:
•
The internal pilot air supply is branched centrally from
the supply connection (1) of the pneumatic interface or
from the multiple connector plate (see Fig. 3/6).
•
The pressure zone, which is supplied via the supply
connection(1) of the pneumatic interface or the multiple
connector plate, must be operated at a pressure
between 3 ... 8 bar.
If the proportional-pressure regulator is to regulate the
operating pressure for the valves on the MPA-S valve
terminal, the valves must be positioned to the right of the
proportional-pressure regulator.
A pressure zone seal and a pneumatic air supply plate is
required for every pressure zone (see diagram).
The ports (1) or (3/5) are:
– for the pressure zone on the outside left of the pneumatic
interface or multiple connector plate.
– for all other pressure zones on the pneumatic supply
plate which lies within the relevant pressure zones.
The position of the supply plate in the pressure zone
(left, centre or right) is optional, but two supply plates
(e.g. of neighbouring pressure zones) must not lie next to
each other.
