Operating the positioner
7.6.2 NOM – Initialization based on nominal range
The calibrated sensor allows the exact valve travel to be measured very accurately. During
initialization, the positioner checks whether the control valve can move through the indicated
nominal range (travel or angle) without collision. If this is the case, the indicated nominal
range is adopted with the limits of travel/angle range start (Code 8) and travel/angle range
end (Code 9) as the operating range.
The maximum possible travel must always be greater than the rated travel entered. If this is
not the case, initialization is automatically canceled (error message Code 52) because the
rated travel could not be achieved.

Configuration is locked again if no settings are entered within 120 s.
