● Assemble the travel sensor (see chapter
3.1 “Assembling the travel sensor”).
l Place the positioner 1 on actuator 3 or
adapter E and fi x it to the travel sensor 2
using a suitable open-end wrench SW 20/
SW 24.
The thread size depends on the
valve to which the positioner is
mounted.
The positioner must not be fi xed
by turning the housing as this may
result in the danger of overturning
the internal stop.
If correctly mounted, the positioner can be
aligned with the corresponding valve.
