digital imput IMP1D-IMP4D

[MiD]

Hi,

I can not get a simple magnetic switch (door open/close) to work on LC3 (1.38b).
It has to be something very simple, but I can not see the clue.
I tried it in a simple configuration: -12V on GND for analog and digital imput and +12 V on INP1D but with no result.
Can someone please give my some information?

Thx!

Hi
Simply make ground short circuit to digital input by magnetic switch.
This way work all door detectors.
