SPLTRNG -

Minimum and maximum value of the input signal in % for which the valve runs through the whole stroke

range.

Factory setting: signal split range bottom = 0%; signal split range top = 100%

Signal split range bottom: I nput of the minimum value of input signal in %:

Signal split range top: I nput of the maximum value of the input signal in %

This function limits the position set-point value range of the positioner by setting a minimum and maximum

value. This makes it possible to split a used standard signal range (4...20 mA, 0...20 mA) into several positioners

(without or with overlap). In this way, several valves can be used alternately, or simultaneously for overlapping

set-point value ranges, as proportional valves.

Splitting of one standard signal range into two set-point value ranges:
