The follow settings are valid for the adaptive 3-point FUZZY controllers:

parameters page 1
(adaptive 3-point
FUZZY)
The set point (W) function is used to specify the nominal value within the measuring range.
Value range: 0.0 mA to 20.0 mA
The set point difference (XSH) function is used to specify switching point 2. The stated
percentage refers to the nominal value.
Value range: 0 % to 20 %
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.
Page 2 contains the following additional setting options for the controller's method of
operating:

parameters page 2
The sense function is used to specify the control direction of the controller. This setting is
not used for 3-point controllers.
Value range: positive / negative
In the case of positive direction of control, the corresponding controller contact activates as
soon as the value drops below the set point. The negative direction of control operates
analogous.
The controller module function can be used specifically to turn the controller on or off.
Value range: On / Off
The limit-contact (L-) and limit-contact (L+) functions are used to specify the lower and
upper limit value for the limit value alarm.
Value range: 0.0mA to 20.0mA
It is possible to turn the limiting value monitoring function off through selecting the off
setting.
The switching hysteresis around the limit contact can be specified in % with the limit-
contact (X2SD) function.
Value range: 0.0 % to 30.0 %
The controller of a different module can be specifically turned off with the limit controller
function as soon as the limit range has been reached.
Value range (module on plug-in connection 1): none / all / module 2 / module 3
Through selecting the module selection function one returns to the controller parameter
module selection.
The page 1 function is used to display the specific parameters of the selected controller.
