Position of the motorized control valve M1 is indicated as a % value.
A 0 - 10 volt signal comes from a position measuring in M1 and is applied to
input S11 (ECA 32). This input voltage is converted to the displayed % value.
Access to conversion (scale) settings.

2.0 volt = 0 %, 10.0 volt = 100 %
The position is measured by means of a 0 - 10 volt signal.
The measured voltage must be converted to a position value by
the controller.
The following procedure sets up the conversion:
Push the dial to see the graph and enter the value sets for the 2
input voltages and related position values.
Position value range: 0 … 100 %
The factory set voltage values (2.0 volt and 10.0 volt) can be
changed in the following two separate menus "Low X" and "High X".
Factory settings: 2.0 , 0 (= 2.0 V / 0 %) and 10.0,100 (= 10.0 V / 100 %)
This means that the "Position" is 0 % at 2.0 V and 100 % at 10.0 V.
Typically, the higher the voltage, the higher the displayed position.
X = Volt
Y = Position
This scaling menu is always displayed, regardless a position signal
is applied.
The position is indicated as 0 when the position signal is not applied.

Filter constant
1x113
The value of the filter constant determines the dampening of the measured
value.
The higher the value, the more dampening.
By this, a too quick change of the measured value can be avoided.
See Appendix “Parameter ID overview”
