Setpoint support points can be entered only for "9.SFCT = FrEE". You may only enter a
monotonously rising characteristic curve, and two successive support values must differ by
at least 0.2%.
The factory setting is "0", "5" ... "95", "100".

10.2.2.5
Description of parameter 31
31.DEBA - dead zone of the controller
In the automatic mode, use this parameter and the "Auto" parameter value to adjust the
dead zone continuously as per the requirements of the control loop in an adaptive manner. If
a control deviation is detected, the dead zone is increased stepwise. A time criterion is used
for the reverse adaptation.
The fixed set value is used for the dead zones in other discrete settings.
The factory setting is "Auto".
10.2.2.6
Description of parameters 32 and 33
32.YA - start of the manipulated variable limit
The factory setting is "0".
and
33.YE - end of the manipulated variable limit
Use these parameters to limit the mechanical actuator travel between the end stops to the
set values. This helps in limiting the mechanical actuating range of the actuator to the
effective flow rate and in preventing the integral saturation of the guiding controller. For this
purpose, see the picture below the also-see link.
Note
Setting
"YE" must always be set greater than "YA".
The factory setting is "100".
