Why doesn't the input card work correctly?

FAQ #100456

Per example: Some input LED's are on even if the signal is low on the input.

 

Problem
After connecting some input wires the LED's are in a undefined status. Some or all LED's are on, even if the signal is low on the input.

Reason
In most cases problems like this are wiring problems. Per example L is not connected correctly.

Solution
The "L" has to be connected to the minus in source operation mode (positiv logic) and to the plus in sink operation mode (negativ logic).
