10.4.2.5 Description of parameters 13 through 33
13.SL0 bis 33.SL20 - Setpoint interpolation points
These parameters are used to assign each setpoint interpolation point a flow metric in units
of 5%. The setpoint interpolation points form a polygonal curve with 20 linear segments,
which models the valve characteristic:

Setpoint characteristic curves, standardization of manipulated variables, and tight closing
function
Input of the setpoint interpolation points is only possible for setting "12.SFCT = FrEE". You
may only enter a monotonically rising characteristic and two consecutive interpolation points
must differ by at least 0.2%.
Factory settings are "0", "5" ... "95", "100".

10.4.2.6 Description of parameters 34
34.DEBA - Dead zone of closed-loop controller
This parameter is used with value "Auto" to adjust the dead zone in automatic mode
continually and adaptively to the requirements of the control loop. If a regulator oscillation is
detected, then the dead zone is incrementally enlarged. The reverse adaptation takes place
using a time criterion.
