Chapter 7 Troubleshooting; 7.1 Fault Alarm And Countermeasures - Powtran PI9100 Series Manual

Chapter 7 Troubleshooting

PI9000 can provide effective protection when the equipment performance is played
fully. The following faults may appear in the process of use, please refer to the
following table to analyze the possible causes and then trouble shoot.
In case of damage to the equipment and the reasons that can not solved, please
contact with your local dealers/agents, or directly contact with the manufacturers to seek
solutions.

7.1 Fault alarm and countermeasures

PI9000 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.
