Fig. 143: 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 big a potential difference
with respect to ZP (max. ± 1 V).
Make sure that the potential difference never exceeds ± 1 V (also not with long
cable lengths).
The following measuring ranges can be configured
Chapter 1.7.4.1.7 “Parameterization”
Chapter 1.7.4.1.9 “Measuring ranges” on page 761
.
Voltage
0...10 V
1 channel used
Voltage
-10 V...+10 V
1 channel used
The function of the LEDs is described under Diagnosis and displays / Displays
1.7.4.1.8 “Diagnosis and state LEDs” on page 755
.
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.
