5.4 Converting the MPA−S valve terminal
The MPA−S valve terminal can be extended/converted at a
later stage. Information on permitted possibilities of combin
ing MPA−S components can be found in the Festo Catalogue
(see www.festo.com\catalogue).
The following conversion work can be undertaken on the
MPA−S valve terminal:
Conversion of the MPA−S valve terminal to internal or
external pilot air
Conversion of the MPA−S valve terminal to different pressure
zones
Adding valve locations (sub−bases)
5.4.1 Conversion to internal or external pilot air
Pilot control of the valve coils can be undertaken with internal
or external pilot air depending on the pneumatic interface or
the multipin sub−base.
Note
Mixed operation of the MPA−S valve terminal with internal
and external pilot air is not intended. Irrespective of the
available pressure zones, all valve coils of the MPA−S valve
terminal are supplied with the same pilot air.
