6.3.2 Manual Mode (MANUAL)
Manual mode is used to maneuver the valve stem manually. During “MANUAL”, the
positioner bypasses the supply air to the actuator. The movement of the stroke does not
affect the positioner’s save data values.
6.3.3 Parameter Mode (PARAM)
AUTO CAL optimizes most of the valve actuator control values. However, in some
instances, hunting or oscillation may occur when the valve actuator control values are not
optimized. Hunting or oscillation can be prevented by adjusting parameter values.
Once parameter values have been changed, the changed values are affective as soon
as you save the value. To save the changes, please ensure to press the “ENTER”
button. There is no need to go back to “RUN” mode after changes have been made
to observe the changes.
6.3.3.1 Dead-Zone (dEAdZONE)
Dead-Zone indicates the percentage of error allowance. In case of high level of packing friction,
which may cause hunting, creating Dead-Zone can stabilize the valve operation
