Spltrng - Signal Split Range - Burkert 8692 Operating Instructions Manual

Type 8692, 8693
Auxiliary functions
25.2.5 S PLTRNG – 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 %;
Type.8693: The SPLTRNG auxiliary function can only be selected when operating as a positioner
(position controller).
P.CONTROL = not activated.
Use this auxiliary function to limit the position set-point value range of the Type 8692/8693 by specifying a minimum
and a maximum value.
As a result, it is possible to divide a utilised standard signal range (4 – 20 mA; 0 – 20 mA; 0 – 10 V or 0 – 5 V) into
several devices (without or with overlapping).
This allows several valves to be used alternately or in the case of overlapping set-point value ranges simultane-
ously as actuating element.
