Note
Mixed operation of the valve terminal MPA−L with internal
and external pilot air is not intended. Independently of the
available pressure zones for various operating pressures
all solenoid coils of the valve terminal MPA−L are supplied
with a common pilot air supply.
The pilot air supply that your valve terminal MPA−L is set for
can be determined from the position of the selector plate (see
Chapter 1.5.3).
