SPLtrng
Splitrange; minimal and maximum values of the input signal (in %) generating the complete displacement of the valve all over the
plug range.
Factory setting:
This additional function enables the set value range of a Top Control Continuous to be restricted by stipulating a minimum and
maximum value. This makes it possible to divide the used unit signal range (4..20 mA, 0..20 mA, 0..10 V oder 0..5 V) over several
Top Control Continuous (without or with an overlap). In this way, several valves can be partially used either simultaneously or in
sequence as a final controlling element (Fig. 6.12).
