0 – 20 mA
4 – 20 mA
Fig. 79: 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).

Data input is complete, once the minimum and maximum characteristic curve interpol-
ation points have been entered.
