Hi,
any chance if someone has came across the similar issue titled "SFMON checksum error param" leading to flashing of relay LED. Didn't know what is causing it. My speculation was the configuration file is imperfect or the corrupted.
Any solution and guide would be grateful. I had to fix this. P138-671 model relay.
