3 wire connection to Select IO/ DIS810
I'm trying to connect a level switch with 3 wire connection to a DIS810 Select I/O.
When connecting all three wires I get channel error.
What I can see should it be possible to load the input with 30mA.
No supervisions are enabled.
Is there something special to think about regarding this?
We are using terminals 1,2,3 like the left most field device in this picture.
