MPA valve terminal with CPX terminal
A pressure zone seal and a supply unit is required for each
pressure zone (see diagram).
The connections 1 or 3/5 are:
for the pressure zone on the outside left of the pneumatic
interface.
for all other pressure zones, on the supply unit which lies
within the relevant pressure zones.
The position of the supply unit in the pressure zone (left,
centre or right) is optional, but two supply units (e.g. of
neighbouring pressure zones) must not lie next to each
other.
By fitting an additional supply unit within a pressure zone you
can supply additional supply air or extract exhaust air.
