The LEDs can be customized to illuminate when a selected FlexLogic operand is in the logic 1 state. The trip and alarm
LEDs can also be customized in a similar manner. To ensure correct functionality of all LEDs, an LED test feature is also
provided.

 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.
For the enhanced and standard front panels, the test consists of the following three stages:
1. All 62 LEDs on the relay are illuminated. This is a quick test to verify if any of the LEDs is "burned." This stage lasts as
long as the control input is on, up to a maximum of one minute. After one minute, the test ends.
2. All the LEDs are turned off, and then one LED at a time turns on for one second, then back off. The test routine starts at
the top left panel, moving from the top to bottom of each LED column. This test checks for hardware failures that lead
to more than one LED being turned on from a single logic point. This stage can be interrupted at any time.
3. All the LEDs are turned on. One LED at a time turns off for one second, then back on. The test routine starts at the top
left panel moving from top to bottom of each column of the LEDs. This test checks for hardware failures that lead to
more than one LED being turned off from a single logic point. This stage can be interrupted at any time.
For the graphical front panel, the test consists of the following stages:
1. All 22 LEDs on the relay are illuminated. This is a quick test to verify if any of the LEDs is "burned." This stage lasts as
long as the control input is on, up to a maximum of one minute. After one minute, the test ends.
2. All the LEDs are turned off, and then one LED at a time turns on with the orange color for one second, then back off.
The test routine starts at the top left panel, moving from the top to bottom for all 14 LEDs. Then the eight pushbutton
LEDs are tested in the same manner. This test checks for hardware failures that lead to more than one LED being
turned on from a single logic point. This stage can be interrupted at any time.
