Programmable target LEDs
In addition to the three fixed LEDs, the relay contains eight LEDs which you can
program to target the status of different type of relay signals. The programmable
LEDs can target the following information:
*
Trip signals from protection elements
*
Alarm signals from protection elements
*
Circuit-breaker position
*
Status of the auto-reclose function
*
Trip lockout
*
Light detected by the arc protection
*
Status of the digital input signals
Route the signals to the LEDs via switchgroups SGL1...SGL8; to LED1 with the
switches of switchgroup SGL1, to LED2 with those of SGL2, and so forth.
For detailed information on the signals, refer to the Technical Reference Manual.
The LEDs are non-latching by default but you can also set them to operate as
latching via switchgroup SGF5.
For instructions on setting the switchgroups, refer to Section 4.2.2.2. How to change
settings.

Target messages
The messages give an overview of protection operations and internal relay faults.
4.3.2.1.
Operation target messages
When a protection element picks up, the text
PICKUP
appears on the display along
with the name of the function. Additionally, in case of a latching pick up target, the
name of the energizing input(s) which caused the fault are displayed (except for the
thermal protection and phase discontinuity protection). The yellow target LED is lit.
