WARNING!
During start-up the actuator stem moves.
Do not touch the actuator stem or obstruct it
to avoid risk of injury to hands or fingers.
If the left or right outer bar element blinks
(reading > 30°), the permissible angle of ro-
tation has been exceeded.
The positioner goes to the fail-safe position
(SAFE).
Make sure that the lever and pin position
match the details as described in section 4.
Note: The positioner has a function to moni-
tor the working range.
If the lever moves too close to the mechani-
cal stops (risk of mechanical damage), the
positioner vents the actuator and the valve
moves to its fail-safe position (S displayed
together with error code E8).
In this case, check the positioner attachment.
Reset the displayed error code by selecting
RST (see section 7.12).
