I have garage door opener which I want to use to control external light during closing or opening. This is how my output looks like at door motor:
In order to achieve light control I have remote switch in my light and remote relay connected to motor. Now the question is when to detect if door is opening or closing. For this purpose I can use Flash output( as a trigger signal) which is supposed to be used by blinking alarm light. But the thing is I don't want my external light to blink but to being turned on constantly.
To solve this problem I've decided to use this time relay which will convert blinking signal to constant one. According to this picture as a trigger signal I can connect anything +/-, L/N
But it doesn't work. I was playing with this relay a bit and it turned out that it is not triggering when I connect red line to +24V but it does when I connect it to the GND
What am I doing wrong?
Why rising or trailing edge is working with ground and not positive?
Manual in english for similar relay - 230V AC only instead of 24V AC/DC
