Related to F002, when the pump reaches the water shortage protecon
value, it will enter the protecon state (check whether the water source
is short of water).

Related toF010, the temperature is higher than the over-temperature
protecon value, and the protecon state is eected (check whether the
temperature of the radiator is too high).

Related to F020, the voltage is lower than the low voltage protecon
value, and the protecon state is eected (check the power supply
voltage value).
