3.2 HUMAN-MACHINE INTERFACE (HMI)

3.2.2 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), usually configured for trip signals. The second group (yellow) and third group
(green) of LED indicators are self-reset and will reset once the condition has been cleared. These LEDs can also be latched
using logic through PLC configuration. For firmware version 7.20 and above, all 15 LEDs are latched through relay settings.
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 light up, verifying their correct operation. When releasing the ESC key, all indicators
programmed with memory, such as tripping LEDs, are reset. For models with enhanced display, there is a reset LEDs
button dedicated for this purpose.
The latched conditions can also be reset via communications using the LED reset input (to configure this signal go to
Setpoint > Relay Configuration > Control Elements > LED RESET INPUT). By default this LED reset input signal is set to
LEDS RESET operation.

3.2.3 Pushbuttons

The front panel provides:
Push buttons: keypad (5 user programmable plus ESC/ESCAPE non configurable), shuttle key or keypad for easy
navigation, command pushbutton to select operations mode.
RS232/USB port: intended for connection to a portable PC.
