Number of flashes
Error type
1
Battery protection cut-out(The voltage is outside the cut-out settiong)
2
Fan over-current cut-out(The fan loads the electronic unit with more than 1Apeak)
3
Motor start error(The rotor is blocked or thedifferential pressure in the refrigetation system is too high>6kg)
4
Minimum motor speed error(If the refrigeration system is too heavily loaded,the motor can nto maintain minimum speed 1850 rpm or controller cannot find the rotor position)
5
Thermal cut-out of electronic unit(If the refrigeration system is too heavily loaded, or if the ambient temperature is high, the electronic unit will run too hot(case temperature>75℃)
6
Controller hardware failure(Controller detects abnormal parameters)
