Error LED and LCD error message
(ii)
The IED has LEDs and LCD screen† so that the automatic supervision function issues a result
for the LEDs and the LCD screen. When the IED is linked with the SAS, it is possible to
transfer the result for the LED and LCD screen using the communication system. Table 9.1-2
shows that which indicators are used for result generation in the function.
Table 9.1-2 Displays on LEDs, LCD, and SAS

‡Note: It depends on the degree of the communication failure.
§Note: If the "In service" has to be turned off while a minor error (level:3) is occurring, set
On for the setting [ErrorLED_cond].
The user can see a current error information in Monitoring sub-menu† on the LCD screen†
(see Figure 9.1-1); Table 9.1-3 shows the six detail information, which the user can examine
carefully using the hexadecimal number. When two or more errors occur at the same time, an
error code is given by the summation of the error codes. That is, when X and Y errors (e.g., X-
error-code '00000002' and Y-error-code '00000004') occur, the sum value '00000006' is screened.
