5.2 PRODUCT SETUP
c) TRIP AND ALARM LEDS

PATH: SETTINGS PRODUCT SETUP
 TRIP & ALARM LEDS

The trip and alarm LEDs are in the first LED column (enhanced faceplate) and on LED panel 1 (standard faceplate). Each
indicator can be programmed to become illuminated when the selected FlexLogic operand is in the logic 1 state.
d) USER-PROGRAMMABLE LED 1(48)

PATH: SETTINGS PRODUCT SETUP
 USER-PROGRAMMABLE
 LED 1
There are 48 amber LEDs across the relay faceplate LED panels. Each of these indicators can be programmed to illumi-
nate when the selected FlexLogic operand is in the logic 1 state.
For the standard faceplate, the LEDs are located as follows.
• LED Panel 2: user-programmable LEDs 1 through 24
5
• LED Panel 3: user programmable LEDs 25 through 48
For the enhanced faceplate, the LEDs are located as follows.
• LED column 2: user-programmable LEDs 1 through 12
• LED column 3: user-programmable LEDs 13 through 24
• LED column 4: user-programmable LEDs 25 through 36
• LED column 5: user-programmable LEDs 37 through 48
Refer to the LED indicators section in chapter 4 for additional information on the location of these indexed LEDs.
The user-programmable LED settings select the FlexLogic operands that control the LEDs. If the
Reset" (the default setting), the LED illumination will track the state of the selected LED operand. If the
"Latched", the LED, once lit, remains so until reset by the faceplate RESET button, from a remote device via a communica-
tions channel, or from any programmed operand, even if the LED operand state de-asserts.
