4.2.2 FRONT LED INDICATORS
The relay provides 16 LED indicators, 15 user programmable plus one non-configurable LED (READY) that shows if the
relay is in service.
Programmable LEDs are divided into groups of 5 LEDs, each of the groups having a different color. The first group of LED
indicators is latched by hardware (red color ones), usually configured for trip signals. The second group (yellow color) and
third group (green color) of LED indicators are self-reset type and will be reset once the condition has been cleared, but can
be latched using logic through PLC configuration.
The ESC key is used to reset any latched led indicator, once the condition has been cleared. Keep the ESC button pressed
for more than 3 seconds; all LEDs will light up, verifying their correct operation. When releasing the ESC key, all indicators
programmed with memory, such as tripping LEDs, will be reset.
The latched conditions can also be reset via communications using the LED reset input (to configure this signal go to
“
Setpoint>Relay Configuration>Protection elements>LED RESET INPUT
”). By default this LED reset input signal is set
to LEDS RESET operation.
