Positioner without air purging of the actua-
tor's spring chamber can be attached ac-
cording to VDI/VDE 3847.
This type of attachment allows the positioner
to be replaced quickly while the process is
running by blocking the air in the actuator.
The signal pressure can be blocked in the ac-
tuator by unscrewing the red retaining screw
(20) and turning the air blocker (19) on the
bottom of the adapter block.
Attachment to Type 3277 Actuator (see Fig.

Required mounting parts and accesso -
ries: see Table 5
Mount the positioner on the yoke as shown
in Fig. 9. The signal pressure is routed to the
actuator over the connecting plate (12), for
actuators with fail-safe action "actuator stem
extends" internally through a bore in the
valve yoke and for "actuator stem retracts"
through external piping.
Only the Y1 port is required for positioner
attachment. The Y2 port can be used for air
purging of the spring chamber.
1. Place follower clamp (3) on the actuator
stem, align it and screw tight so that the
mounting screw is located in the groove
of the actuator stem.
