3.5 ERROR CODE DURING OPERATION
The IED performs continuous self-checking. If the IED detects an error it displays an error message, logs a
maintenance r
ecord 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.
