Device Functionality
2.1 Front Fascia
Trip Ready LED
The steady illumination of Trip Ready LED indicates that required CT current 0.20 ⋅ I
current) in 1-phase or 0.10 ⋅ I
the relay and the relay is having sufficient energy to trip through the impulse output.
Low Battery LED
The low battery LED indicates when the battery voltage falls below the sufficient operating voltage.
User-Programmable LEDs
The 7SR45 Argus Relay consist of 4 user-programmable LEDs which can be configured to protection and
miscellaneous functions. The LEDs (L4 to L7) are programmed to be illuminated as RED. The 4 user-program-
mable LEDs are mapped to Phase IL1/A, IL2/B, IL3/C, IE/E by default.
User-Programmable LED Configuration
The 4 user-programmable LEDs are assigned to any functions using OUTPUT CONFIG > OUTPUT MATRIX
menu.
The 4 user-programmable LEDs are mapped to Phase IL1/A, IL2/B, IL3/C, IE/E by default. This default configura-
tion shall be printed on one side of the paper label provided with the decal. If you decide to change the config-
uration for the programmable LEDs, then you must write the name of the function (to which the program-
mable LED is mapped) on the rear side of the paper label provided with the decal.
If the LEDs are mapped to any protection or phase function, then they will be turned ON when the function
trips. For example if an LED is mapped to the 51-1 function, then the LED will be turned ON when the relay
trips due to 51-1 fault.
If the LEDs are mapped to a miscellaneous function, then the LEDs turn ON as and when the event occurs. For
example if the LED is mapped to BI 1 operated, then the LED is turned ON when BI 1 input is present.
