RED light on Controller 10R-05-4003

Brand new 2 battery Victron solar system used to run Oloid 400. Started right up and ran for 2days and then just quit- red light comes on 10R-05-4003 Controller. Ran diagnostics and indication is either overcharge or BMS- is not overcharge as each cell is 3.35. Is there a reset, a fuse, or do I need to replace the controller or is it something else

@dgb Can you elaborate a bit maybe on all the connected equipment? Is there a ve.bus connection? The red light also can also indicate over teperature if connected in a ve.bus system.
