Having a hard time here. 3 stop hydro, dual car stations. Logging 1209s on every hall push button board and cio board. The faults log often and it’s random what boards will register under the fault. I’ve tried turning off cab lights to rule out ballast interference, checked the shielded cable and made sure it wasn’t wound up anywhere. changed the crip board and cio, Still throwing faults. My suspicion right now that doesn’t have alot of basis is maybe the power supply is giving off a signal that is interfering with the LON cable and shielded pair. The power supply is giving off a high frequency buzzing. Any thoughts?
