purging , connect the Y1 port of the
adapter block to the signal pressure con-
nection of the actuator. Seal the Y2 port
with a blanking plug.
For
double-acting actuators and actua -
tors with air purging , connect the Y2

VDI/VDE 3847-2
Attachment according to VDI/VDE 3847-2
for SRP (single-acting) and DAP (double-act
-
ing) rotary actuators in sizes 60 to 1200
with NAMUR interface and air purging of
the actuator's spring chamber allows the di-
rect attachment of the positioner without ad-
ditional piping.
Additionally, the positioner can be replaced
quickly while the process is running by
blocking the air in single-acting actuators.
Blocking the actuator in place (see
Fig. 5-15):
1. Unscrew the red retaining screw (1).
2. Turn the air blocker (2) on the bottom of
the adapter block according to the in-
scription.
