It doesn't look like the high salt light is on.
In any case, the amps determine when the high salt light comes on.
For a T-15, the high salt light comes on at 8.0 amps (a few software revisions shut down at 10 amps)
The amps depend on the salinity and the water temperature.
At 52 degrees, the high salt might not come on until the salinity gets to 4,200 ppm.
At 96 degrees, the high salt light might come on 2,800 ppm. This can be a problem for heated pools, especially when the cell is after a 400,000 btu/hr gas heater where the exit temperature can be up to 16.8 degrees Fahrenheit higher than the actual water temperature.
The T-3, T-5, T-9 and the T-15 cells have different amp limits.
You have to make sure that the cell type matches the cell type setting in configuration.
