5.4.2 Converting the MPA valve terminal to different pressure zones
The MPA valve terminal can be fitted with the following
number of pressure zones depending on the connection vari
ant:
Electrical
connection variant MPA valve terminal with ...
connection variant
CPX terminal MPM connection MP connection
Pressure zones 1 ... 8 1 ... 12 1 ... 2
Table5/9: Number of pressure zones
The pressure zones are formed either by special sub−bases or
by special sheet metal seals.
On the sub−bases with pressure zone separation only supply
channel (1) is separate. Separation is made in the centre of the
sub−base, i.e. on
the MPA1 after the second valve location
the MPA2 after the first valve location.
The following channels can be separated with the sheet metal
seals:
only the supply channel (1)
supply channel (1) and exhaust channels (3 and 5)
only exhaust channels (3 and 5)
You can recognize whether your MPA valve terminal is
equipped with pressure zones either by the marking on the
sub−base (see Table5/10) or by the marking on the seal (see
Table5/11).
