The ID-proportion of the controller can be adjusted with the prelim time (Tv) and delay
time (Tn) functions.
Value range:
The absolute interval between switching point 2 and the set point can be specified with
the set point difference (LW) function.
Value range: 0 mV to ± 1000 mV
The switch difference (X2SD) function is used to specify a switch hysteresis around
switching point 2. The stated percentage refers to the absolute value of switching point 2.
Value range: 0.0 % to 30.0 %
Through selecting the module selection function one returns to the controller parameter
module selection.
Page 2 displays additional parameters on a second page of settings.
The following settings apply to the 3-point PID controller:

(3-point PID)
The set point (W) function is used to specify the nominal value within the measuring
range.
Value range: 0 mV to 1000 mV
The proportionality factors for the P-proportion of the respective controller can be
specified with the proportional area (XP1) and proportional area (XP2) functions.
Value range: 0 % to 999 %
The ID-proportion of the controller can be adjusted with the prelim time (Tv) and delay
time (Tn) functions.
Value range:
Switching point 2 can be adjusted with the set point difference (XSH) function.
Value range: 0 % to 20 %
Through selecting the module selection function one returns to controller parameter
module selection.
Page 2 displays additional parameters on a second page of settings.
The following settings apply to the 2-point-FUZZY controller:

The set point (W) function is used to specify the nominal value within the measuring
range.
Value range: 0 mV to 1000 mV
