Magnetic Contact Logic

[Chris Pitman]

Just built some built in wardrobes with led lighting via DMX and used some magnetic contacts in tops of doors, have a small problem as the doors are push to open getting a problem.

Loxone sees 24v when doors closed but as door is pushed in to open it goes 0V then as door springs out it sees 24v as door opens past contact again then 0v as door is open any ideas how to prevent this?

You can try the following logic diagram, which seems to work for your case. At the top there is a Saving Switch-on Delay function block, which gives a steady output or a Delay Pulse function block at the bottom, which gives an adjustable pulse at the output. In either case you must set the duration of delay at the right time (for each function block), from the time that you push the door to open until is fully open.

Maybe increase magnet strength so it only activates, for example, when its open 20mm

Thanks had a play with the two blocks seem to have found a combination that works,

Tried the magnet option the tops of the doors have a metal cover strip which is messing with the inset magnet hence the problem, door only pushes in like 3mm but enough on a couple doors to cause problems.
