AC450 Unlisted Halt Codes
I have an AC450 with PM511V board that is giving me an U1 fault code but with ONLY the BC light being lit (run, halt both unlit).
This is causing an issue where we have lost communication with the controller and just seeing the mode set as INVALID and forcing the mode to mode 1. This does not allow us to run more than one converter at a time incase a fault takes out both converters at the same time.
