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 being affected as soon as you save the value. To
save the changes, please ensure to press “ENTER” button. There is no need to go back to “RUN” mode after changes
are being made to observe the changes.
