The relationship between control variable and dosing output is
determined by the internal dosing factor.
If a positioner with feedback is used as the dosing output, it can be
linearized using several support points. At least two points are
required (0/100 %). It possible to define 2, 3, 6 or 11 support points
with definite steps. In the menu „Dosing“ - „Ym Calib. Points“ the
number can be defined. The support points then have to be set in
menu „Dosing“ - „Ym Calib. Manual“(see5.3.12 “Positioner
calibration with SFC (application 3) or single feed forward
(application 2)”).
The controller output is calculated in this operating mode as
follows:
Yout = Wq x DF
Wq
control variable 1 flow rate in %
DF
set dosing factor in %
The figure below shows the output dosing capacity depending on
the flow rate Wq and the set dosing factor.
