Custom Led Labeling - GE N60 Instruction Manual

CHAPTER 4: INTERFACES
• PHASE C — Indicates phase C was involved
• NEUTRAL/GROUND — Indicates that neutral or ground was involved
User-programmable indicators
The second and third panels 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. See the User-programmable LEDs section in chapter 5 for the settings used to program
the operation of the LEDs on these panels.
USER-PROGRAMMABLE LEDS
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
• BREAKER 1(2) OPEN — The breaker is open
• BREAKER 1(2) CLOSED — The breaker is closed
• BREAKER 1(2) TROUBLE — A problem related to the breaker has been detected
• SYNCHROCHECK NO1(2) IN-SYNCH — Voltages have satisfied the synchrocheck element
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.
