SKR3 and Relay V1.2 RepRapFirmware

[chimir]

I am using SKR3 board with RepRapFirmware from official bigtreetech github. When connected via Relay V1.2, the power goes off after a few seconds. How do I set it to work correctly?

The board.txt file shows the settings:

atx.powerPin = E.4
atx.powerPinInverted = false

in the file config.g at the very beginning of the file, the settings are indicated:

M80 C "PSON"

The "PSON" connector doesn't work, use the "probe" pin C.13,
