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)
