Flame Detector on MKS-DLC32 board

Hello!
So, as I’m on vacation and have free time, I thought I should figure out how to put a flame detector on my laser machine.
The board is an MKS-DLC32 that has a “probe interface” port that, according to the manual, can be configured as a flame detector.

From my research there is a parameter $37 that activates or deactivates the function (1 or 0 respectively)
Although this parameter does not appear in Edit - Machine settings, in the “console” window it appears and if I execute the command to activate or deactivate I get the return “ok” and I can confirm that the command was effectively changed through the command to verify the state of the parameter ($37 in this case).

Turns out nothing happens when I simulate the flame detector signal.

Has anyone, with this card (I’ve seen that there are some working around), managed to get the “probe/flame detector” function to work?
