User-programmable indicators
The second and third panels provide 48 amber LED indicators whose operation is controlled by the user. Custom labelling
can be done.
User customization of LED operation is of maximum benefit in installations where languages other than English are used
to communicate with operators. See 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 the following:
• 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 next section.

• IN SERVICE — Indicates that control power is applied, all monitored inputs/outputs and internal systems are fine, the
relay’s test mode is disabled, and the relay is in (online) Programmed mode (under Settings > Product Setup >
Installation)
• TROUBLE — Indicates that the relay has detected an internal problem. Check the self-test messages outlined at the
end of the Commands and Targets chapter, and view the event records under Actual Values > Records. For a beta /
pre-release, this LED is always on.
