to the rated travel by the lever on the back of
the positioner and the pin inserted into the
lever.
The travel tables on page 21 show the
maximum adjustment range at the position-
er. The travel that can be implemented at the
valve is additionally restricted by the selected
fail-safe position and the required compres-
sion of the actuator springs.
The positioner is equipped with the M lever
(pin position 35) as standard.
