FE-31 is for Full-water detection mode.
If set to 0, set any terminals(default DI4/DI5)function code to 51/52
，
two terminals enabled in same time could
activate Full-water protection and two terminals disabled in same time could activate exit Full-water protection.
One of the terminals enabled, remains its status without any change.
FE-33/FE-34 for detection time of full-water protection and exit time of full-water protection;
FE-35 for analog sensor damaged Thresholds
，
if FE-31 set to analog detection, and analog feedback is larger than
the setting detectionThreshold value of FE-35. Judge it as analog sensor faults. Display A.Prb, and stop running;
FE-31 set to 0, close sensor faults detection.

As software estimating solar cells’ DC current value, this parameters will correction this estimation value, U0-06
displays correction current, correction formula is U0-06 =(estimation value * FE-36)+ FE-37

According output power(U0-05) calculate output flow speed(U0-13), User reference(P-Q curve), input to FE-38
～
FE-47, software automatically calculate U0-13
