The relationship between the flow control variable and the dosing
output is determined using the internal dosing factor. This can be
varied up to max. 400%.
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“ it is
possible to set the number of points used. The support points then
have to be set in menu „Dosing“ - „Ym Calib.Manual“ (see 5.3.5
“Positioner calibration”).
The controller output is calculated in this operating mode as
follows:
Yout = Wq x DF
Wq
Control variable 1 flow 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.
