CHAPTER 5: SETTINGS
5.3.9.3 Analog channels
SETTINGS  PRODUCT SETUP  OSCILLOGRAPHY  ANALOG CHANNELS
 ANALOG CHANNELS

These settings select the metering actual value recorded in an oscillography trace. The length of each oscillography trace
depends in part on the number of parameters selected here. Parameters set to "Off" are ignored. The parameters available
in a given relay depend on
• the type of relay,
• the type and number of CT/VT hardware modules installed, and
• the type and number of analog input hardware modules installed
A list of all possible analog metering actual value parameters is presented in Appendix A: FlexAnalog Parameters. The
parameter index number shown in any of the tables is used to expedite the selection of the parameter on the relay display.
It can be time-consuming to scan through the list of parameters via the relay keypad and display — entering this number
via the relay keypad causes the corresponding parameter to display.
If there are no CT/VT modules and analog input modules, no analog traces appear in the file; only the digital traces appear.

5.3.10 User-programmable LEDs

5.3.10.1 Menu
SETTINGS  PRODUCT SETUP  USER-PROGRAMMABLE LEDS
 USER-PROGRAMMABLE
 LEDS
The 48 amber LEDs on relay panels 2 and 3 can be customized to illuminate when a selected FlexLogic operand is in the
logic 1 state. The trip and alarm LEDs on panel 1 can also be customized in a similar manner. To ensure correct
functionality of all LEDs, an LED test feature is also provided.
5.3.10.2 LED test
SETTINGS  PRODUCT SETUP  USER-PROGRAMMABLE LEDS  LED TEST
 LED TEST

When enabled, the LED test can be initiated from any digital input or user-programmable condition, such as a user-
programmable pushbutton. The control operand is configured under the
LEDs, including the LEDs of the optional user-programmable pushbuttons.
