Adjusting the analog input
The input can be adjusted to the sensor with the aid of the following parameters.
For non-temperature sensors, a scaled value is calculated from the sensor signal:
For temperature outputs, the scaled value is calculated from linearisation 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 * 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" 3000 , PT50/100/1000, Cu50/100
Linear or square (quad.) curve of the sensor used; can be selected for analog sig-
nals. °C, °F, Kelvin physical measured variable, can be selected for temperature
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".
