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)
