Festo MPA Series - MPA−S Valve Terminal with Pressure Zone Separation

Festo P.BE−MPA−EN en 0910d
Note
· Use closed−loop regulated external pilot air (3 ... 8 bar).
Reliable faultless operation of the MPA−S valve terminal
is then possible, e.g. even with fluctuating operating
pressure.
· The external pilot air is supplied centrally via the pilot
port (12/14) on the pneumatic interface or the multiple
connector plate. This is the case even if the MPA−S
valveterminal is operated with different pressure zones.
· Set the external pilot air supply to correspond to the
operating pressure at which these valves are operated
(seediagrams in appendix A, Fig.A/1, Fig.A/2 and
Fig.A/3).
3.4.2 MPA−S valve terminal with pressure zone separation
Basic information on pressure zone separation is provided in
chapter 1, section Pressure zone separation".
Note
· Operate the valves with ident. code I (2 x 2/2−way valve)
in a separate pressure zone with separate exhaust
channnel (5) if the MPA−S valve terminal is also fitted
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.3/3).
· 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.
