Splitting of signal range (Split range) (S/HART)
Max. and min. values of the input signal in % for which the valve runs through the entire stroke range.
Factory setting: SR = 0 (%); SR = 100 (%)
Entering the minimum value of the input signal in % (0
... 75 (%) of the standard signal range)
Entering the maximum value of the input signal in %
(25 ... 100 (%) of the standard signal range)
Splitting a standard signal range into two setpoint ranges
With this supplementary function you can limit the position setpoint range of the SIDE Control (S/HART)
by specifying a minimum and a maximum value. In this way it is possible to split the standard signal
range (4..20 mA) over several SIDE Control S/HARTs (with or without overlap). In this way, several
valves may be used
alternately or, with overlapping setpoint ranges, simultaneously as servo
components.
NOTE This function is active only in operation as a positioner
