ProMinent DULCOMETER - Control parameter [xp]

10.4 Control parameter [xp]
The xp value is the controller amplification factor. The xp value relates to the measuring
range end of a controller and is entered as an absolute value. For pH for example
xp=1.5.
For measured variables such as chlorine, the sensor measuring range is selected. The
sensor measuring range corresponds to the measuring range end.
For pH, the measuring range end is 15.45. Here the default xp value is 1.54 (corresponds
to ± 1.54 pH). The xp value states that for a deviation of ± 1.54 from the setpoint, the
control variable equals ± 100%. The smaller the xp value, the more
‘forcefully’ the con‐
trol reacts, however the control also moves slightly into the over-control range.
