4.2 FACEPLATE INTERFACE
b) LED PANELS 2 & 3
These panels provide 48 amber LED indicators whose operation is controlled by the user. Support for applying a custom-
ized label beside every LED is provided.
User customization of LED operation is of maximum benefit in installations where languages other than English are used to
communicate with operators. Refer to the USER-PROGRAMMABLE LEDs section in Chapter 5 for the settings used to
program the operation of the LEDs on these panels.
c) DEFAULT LABELS FOR LED PANEL 2
The default labels are meant to represent:
GROUP 1...8: The illuminated GROUP is the active settings group.
BREAKER n OPEN: The breaker is open.
BREAKER n CLOSED: The breaker is closed.
BREAKER n TROUBLE: A problem related to the breaker has been detected.
SYNCHROCHECK NO n IN-SYNCH: Voltages have satisfied the synchrocheck element.
RECLOSE ENABLED: The recloser is operational.
RECLOSE DISABLED: The recloser is not operational.
RECLOSE IN PROGRESS: A reclose operation is in progress.
RECLOSE LOCKED OUT: The recloser is not operational and requires a reset.
The relay is shipped with the default label for the LED panel 2. The LEDs, however, are not pre-programmed. To match the
pre-printed label, the LED settings must be entered as shown in the USER-PROGRAMMABLE LEDs section of the SET-
TINGS chapter in the D60 manual. The LEDs are fully user-programmable. The default labels can be replaced by user-
printed labels for both LED panels 2 and 3 as explained in the next section.
