8. Fault alarm and countermeasures
JI150 can provide effective protection when the equipment performance is played fully. In case of abnormal fault, the
protection function will be invoked, the inverter will stop output, and the faulty relay contact of the inverter will start, and
the fault code will be displayed on the display panel of the inverter. Before consulting the service department, user can
perform self-check , analyze the fault cause and find out the solution according to the instructions of this chapter. If the
fault is caused by the reasons as described in the dotted frame, please consult the agents of inverter or directly contact
with our company.
