Adjusting the analog input
The input can be adjusted to the sensor with the aid of the following parameters.
For current, voltage and resistance sensors, a scaled value is calculated from the sensor signal:
For temperature outputs, the scaled value is calculated from linearization tables. The temperature
value can be converted to degrees Celsius, degrees Fahrenheit or Kelvin. In addition, the tempera-
ture value can be corrected by means of an offset.
Description
Selects the signal type of the connected sensor. Parameters marked with an aster-
isk (*) can only be selected with the universal input option.
Configures the sensor connection in 3-wire or 4-wire technology. Can only be
selected for "Signal type" 30-3000 , PT50/100/1000, Cu50/100
Linear or quadratic (quad.) characteristic of the sensor used. Can be selected for
analog signals. °C, °F, Kelvin physical measured variable, can be selected for tem-
perature sensors.
Signal damping of measuring input with 1st order low pass. Time constant can be
selected from 0 to 99.9 sec.
The technical unit or an arbitrary text for the measured value of the sensor can
be configured here. Max. length 9 characters.
Number of places after the decimal point for displaying the measured value.
Start value of measured value, can be selected for analog signal types
End value of measured value, can be selected for analog signal types
Shifts the zero point of the response curve. This function is used to adjust the sen-
sor.
Comparative temperature for thermocouple measurement. An internal cold junc-
tion (= Intern) or a constant value (= const) can be selected.
Fixed comparative temperature.
This can only be selected if const is set for "Cmp. Temp".
