Fig. 27: Connection example
By connecting the sensor's negative pole of the output voltage to AGND, the
galvanically isolated voltage source of the sensor is referred to ZP.
The following measuring ranges can be configured Ä Chapter 1.6.2.2.2.6 “Parameterization”
on page 444 Ä Chapter 1.6.2.2.2.9 “Measuring ranges” on page 449
Voltage 0 V...10 V 1 channel used
Voltage -10 V...+10 V 1 channel used
The function of the LEDs is described under Displays Ä Chapter 1.6.2.2.2.7 “Diagnosis”
on page 447.
In order to avoid error messages or long processing times, it is useful to configure unused
analog input channels as "unused".
