Signal split range
Min. and max. values of the input signal as % for which the valve runs through the entire stroke range.
Factory setting: Min = 0 %; Max = 100 %
This function is effective only during operation as a position controller.
Use this auxiliary function to limit the position set-point value range of the positioner by specifying a minimum and a maximum
value. As a result, it is possible to divide a utilised unit signal range (4 – 20 mA, 0 – 20 mA, 0 – 10 V or 0 – 5 V) 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.
