The signal pressure from the positioner is
routed over the signal pressure connection of
the connecting plate (9, Fig. 25 left) to the
actuator diaphragm chamber. To proceed,
first screw the connecting plate (9) included
in the accessories onto the actuator yoke.
− Turn the connecting plate (9) so that the
correct symbol for the fail-safe action
"actuator stem extends" or "actuator stem
retracts" is aligned with the marking (Fig.
25, below).
− Make absolutely sure that the gasket for
the connecting plate (9) is correctly insert-
ed.
− The connecting plate has threaded holes
with NPT and G threads. Seal the thread-
ed connection that is not used with the
rubber seal and square plug.
3. Mount connecting plate (6) or pressure
gauge bracket (7) with pressure gauges
on the positioner, making sure the two
seals (6.1) are seated properly.
4. 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.
