 TRIP & ALARM LEDS

The trip and alarm LEDs are in the first LED column (enhanced and graphical front panels) and on LED panel 1 (standard
front panel). Each LED can be programmed to turn on when the selected FlexLogic operand is in the logic 1 state.

 LED 1
For the enhanced and standard front panels, there are 48 amber LEDs across the relay LED panels. Each of these
indicators can be programmed to illuminate when the selected FlexLogic operand is in the logic 1 state.
For the standard front panel, the LEDs are located as follows:
• LED Panel 2 — User-programmable LEDs 1 through 24
• LED Panel 3 — User programmable LEDs 25 through 48
5
For the enhanced front panel, 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
See the LED Indicators section in chapter 4 for 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 tracks the state of the selected LED operand. If the
"Latched," the LED, once lit, remains so until reset by the front panel
communications channel, or from any programmed operand, even if the LED operand state de-asserts.
