to the analog inputs
NOTICE!
Risk of faulty measurements!
The negative pole/earthing potential at the sensors must not have too large a
potential difference with respect to ZP (max. ± 1 V within the full signal range).
Make sure that the potential difference never exceeds ± 1 V.
Voltage 0...10 V 1 channel used
Voltage -10 V...+10 V 1 channel used
For the measuring ranges that can be configured, plese refer to the sections Measuring Ranges
Ä Chapter 1.7.1.2.10 “Measuring Ranges” on page 731 and Parameterization Ä Chapter
1.7.1.2.7 “Parameterization” on page 721.
To avoid error messages, configure unused analog input channels as "unused".
Connection of Passive-type Analog Sensors (Current) to the Analog Inputs
The following figure shows the connection of passive-type analog sensors (current) to the
analog input AI0. Proceed with the analog inputs AI1 to AI3 in the same way.
