Fig. 83: Settings dialogue actual value sensor
Select one of the types of use "Differential pressure sensor", "Temperature sensor" or
"External sensor" as one of the usage types.
NOTICE
If another usage type has been set to "Not configured" in the "Select type of use"
menu, check whether the analogue input is already used for another type of use.
If necessary, select a different source.
Select the "Signal type" after selecting the actual value sensor.
Signal type: analogue input (AI3)
For temperature sensor
PT1000
0 – 10 V
2 – 10 V
0 – 20 mA
4 – 20 mA
Fig. 84: Signal type
When selecting the signal type "PT1000", all settings for the sensor input are com-
pleted and all other signal types require additional settings.
For the transfer of analogue signal values to actual values, only the transfer ramp is now
defined. For this purpose, the minimum and maximum support point of the character-
istic curve is specified and the respective actual values are amended (MIN signal/value
assignment and MAX signal/value assignment).
NOTICE
If the analogue input is configured to the signal type PT1000 for a temperature
sensor, a "temperature correction value" can be set to compensate for the electrical
resistance if the sensor cable is longer than 3 m.
Use analogue input as
actual value input for
temperature sensor
, e.g. for
temperature T-c.
set analogue input to the
signal type 0...10 V
.
