Initialization based on nominal range (NOM)
The calibrated sensor allows the effective valve travel to be set very accurately. During initial-
ization, the positioner checks whether the control valve can move through the indicated nom-
inal 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.
