12.4 Soft Limits
Soft Limits are software controlled travel stops for the valve assembly. Since they are software controlled, soft limits are
not held in the memory on loss of signal or air because the software is not able to control the valve in these situations. If
soft limits are active, they show as grey areas at either end of travel on the main dashboard view.
