2. If the mounted interlinking board is the last one in front of the right M PA end plate, you must insert
the end piece type MPA into this interlinking board.

3. Mount the sub-base to the adjacent components ( section 5.3.7).
4. Mount the electronics module into the sub-base ( section 5.3.6).
5. Mount all th e valves and blanking plates again onto the sub-base ( section 5.3.4).
5.4 Conversion of the MPA-S valve terminal
The MPA-S valve terminal can be subsequently expanded/converted. Information on per-
missible possible combinations of MPA-S components ca n be found in the Festo Cata-
logue ( www.festo.com/catalogue).
The following conversion work can be undertaken on the MPA-S valve terminal:
– Conversion between ducted and unducted exhaust air
– Conversion to internal or ext ernal pilot air supply
– Conversion to different pressure zones
– A dding valve positions (sub-bases)
– A dding supply plates to the pneumatic supplemental supply.
5.4.1 Conversion to internal or external pilot air supply
Pilot control can be undertaken with internal or external pilot air, dependent on the pneumatic interface
or the multi-pin plug connection plate.
Note
Mixed opera tion of the MPA-S valve terminal with internal and external pilot air supply is
not intended. Independent of t he available pressure zones, all pilot controls of the
MPA-S valve terminal are supplied with the same pilot air supply.
You can ascertain the pilot control variant for which your MPA-S is equipped by the following features
listed in chapter 3, Tab. 3.5.
