12.2.2 SPLITRANGE -

signal split range
Minimum and maximum values of the input signal as a % for which the valve runs through the entire stroke range.
Factory setting: Lower signal range split = 0 %; Upper signal range split = 100 %
Lower value split range:
Upper value split range:
Use this function to limit the position set-point value range of the positioner by specifying a minimum and a
maximum value. This makes it possible to divide a unit signal range that is used (4 – 20 mA, 0 – 20 mA) into
several positioners (without or with overlapping). This allows several valves to be used alternately or, in the case
of overlapping set-point value ranges, simultaneously as actuators.
To split a unit signal range into two set-point value ranges:
Valve stroke [%]
Set-point value range
