Overload warning for load cell channels

Notify tank operator if load cells are recording values close to their upper limit

Safe overload = 150% of full scale capacity for each channel. I would recomend warnings at 100% and 125% of full scale.

FS Capacity of each channel:

Mx = 47 N-m
My = 172 N-m
Fz = 1885 N
Mz = 222 N-m

Should we use this to cause the system to shut down if overload reaches some threshold? These moments/forces are caused by the turbine running, in practice, so automating to stop the rotor and stop the carriage if said threshold is met may be a good idea? Could include an ovverride switch if that was helpful for some reason.
