Control direct.
Significance Control direction
Display Acid/alkaline for pH
direct/invers for conductivity
Explanation Defines with which medium correction is performed.
Example pH: control direction "Acid": Lowering pH-value by dosing acid
Conductivity: control direction "direct": Raising conductivity by dosing
brine
Xp
Significance Proportional factor
Display Percentage (%) with factor
Explanation The control amplification is determined with the proportional factor.
The lower the proportional factor Xp is selected in % , the greater the
deviation from the setpoint is amplified, and the more quickly the cont-
roller attempts to control the deviation from the setpoint.
The control amplification factor is calculated with the formula:
Factor = (1/Xp) x 100 %
Setting range The parameter Xp can be adjusted from 1 % (factor 100) ... 1000 %
(factor 0.1).
Xsh
Significance Neutral zone
Display Percent (%)
Explanation The parameter Xsh only applies for 3-point controllers.
No control output occurs in the neutral zone.
Setting range The parameter Xsh can be adjusted from 0 ... 5 % (based on the
measuring range).
Ymax
Significance Dosing rate limitation
Display Percent (%)
Explanation The parameter Ymax only applies for
Positioner with feedback
Dosing pumps
Pulse pumps
Controller with mA output
Ymax defines the maximum control output to the dosing equipment.
The control parameter corresponds to electronic dosing limitation of the
dosing equipment.
Setting range The parameter Ymax can be set from 0 ... 100 %.
