CHAPTER 7: COMMANDS AND TARGETS
• What to do: Contact the factory and supply the failure code noted in the display. The "xxx" text identifies the failed
module (for example, F8L).
For Module Failure 31, a new process card hardware is available. The process card hardware has been enhanced to
support new features, such as fast distance protection, Synchrophasors Frequency, and Rate of Change of Frequency
calculations to conform to C37.118 - 2005 standard. The new functionality leveraging the hardware is supported with
firmware revision 7.25 and above. When using an older revision of the process card with a new firmware revision
(7.25), Module Failure 31 indicates the limited functionality. If your application requires the new functionality, then new
process card hardware is required and otherwise you can continue using the existing hardware. To know the revision
of your hardware, contact the factory.
