7.6.2 NOM – Initialization based on nominal range
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.
The maximum possible travel must always be greater than the nominal travel entered. If this
is not the case, initialization is automatically canceled (error message Code 52) because the
nominal travel could not be achieved.
