5.3 Troubleshooting
The IS580 provides alarm information and protective functions. When a fault occurs, IS580 implements the
protective function, stops output, makes the fault relay act, and displays the fault code on the operation panel.
Before contacting Inovance for technical support, you can rst determine the fault type, analyze the causes, and
perform troubleshooting according to the description in this chapter. If the fault cannot be rectied, contact the
agent or Inovance.

Note
•
Err47 and Err48 are related to the multi-pump convergent ow solution. Err08 cannot be reset, please
contact Inovance.
•
If only one pump is controlled, disable DI5. If the multi-pump convergent ow solution is used, refer to
descriptions in Appendix C.
