Fig. 91: Connection of active-type sensors (voltage) with no galvanically isolated power supply
to the analog inputs
CAUTION!
Risk of faulty measurements!
The negative pole 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.
The following measuring ranges can be configured
Chapter 1.6.3.1.2.6 “Parameterization”
Chapter 1.6.3.1.2.9 “Measuring ranges” on page 606
Voltage
0 V...10 V
1 channel used
Voltage
-10 V...+10 V
1 channel used
For a description of the function of the LEDs, please refer to Diagnosis and displays / Displays
Chapter 1.6.3.1.2.8 “State LEDs” on page 606
To avoid error messages from unused analog input channels, configure them 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.
