Maybe the softstart was added and something goofy was done. For a softstart the jumper from J66 to J67 should be on which ties DCC directly to the run output. Then you set Invert DCC to a 1. Maybe you could get that fault from a problem with the run output or the DCC input but I’ve seen a relay added to simulate DCC instead of jumping it to run and inverting it in software. If there are extra relays I’d look there. A 211 doesn’t need any extra relays for a Siemens softstart.
