USER-PROGRAMMABLE INDICATORS:
The second and third provide 48 amber LED indicators whose operation is controlled by the user. Support for applying a
customized 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.

DEFAULT LABELS FOR LED PANEL 2:
The default labels are intended to represent:
• GROUP 1...6: The illuminated GROUP is the active settings group.
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 chapter 5. The
LEDs are fully user-programmable. The default labels can be replaced by user-printed labels for both panels as explained
in the following section.
