ERROR CODE DURING OPERATION

The IED performs continuous self-checking. If the IED detects an error it displays an error message, logs a
maintenance record and after a short delay resets itself. A permanent problem (for example due to a hardware
fault) is usually detected in the power-up sequence. In this case the IED displays an error code and halts. If the
problem was transient, the IED reboots correctly and continues operation. By examining the maintenance record
logged, the nature of the detected fault can be determined.

Programmable scheme logic error due to excessive execution time. If
the IED powers up successfully, check the programmable logic for
feedback paths.
Other error codes relate to software errors on the main processor
board, contact the local service centre.
If the setting is Enabled, disable the test mode and make sure the Out of
Service LED is OFF.
