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.

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).
