By connecting the sensor's negative pole of the output voltage to AGND, the
electrically isolated voltage source of the sensor is referred to ZP.
The following measuring ranges can be configured for AX521 Ä Chapter 1.5.2.2.4.6 “Parame-
terization” on page 531 and for AX522 Ä Chapter 1.5.2.2.5.6 “Parameterization”
on page 555:
Voltage 0 V...10 V 1 channel used
Voltage -10 V...+10 V 1 channel used
In order to avoid error messages or long processing times, it is useful to configure unused
analog input channels as "unused".
