Keys Description
This push-button is used to return the relay display to its initial status or one
level up in the menu structure. Press CANCEL to return to the previous menu
or to cancel the value.
This push-button is used to reject any alterations to a setting while in the edit

Light Emitting Diode (LED)
Indication LEDs
The 7SR46 Argus relay provides 2 non-programmable LEDs and 2 user-programmable LEDs.
The LED functions are:
Table 2-1 LED Functions
LEDs Parameters Indication Color Functions
LED 1
HEALTHY
Green Indicates the relay protection function in a
healthy state
LED 2
O/C
1
Red LEDs L2 to L3 are user-programmable LEDs. They
indicate when the respective mapped function is
triggered.
By default, these LEDs are mapped to O/C (phase
overcurrent) and E/F (earth fault) functions.
LED 3
E/F
1
Red
LED 4
LOW BATTERY
Amber (continuous) Indicates when the battery voltage is less than
the operating level
Amber (blinks) Critical battery condition
Healthy LED
The steady illumination of Protection HEALTHY LED indicates that the required CT current 0.8 ⋅ I
smin
(1-phase)
or 0.4 ⋅ I
smin
(3-phase) or auxiliary power supply is applied to the relay, which indicates a healthy relay.
Low Battery LED
The low battery LED indicates when the battery voltage falls below the operating voltage.
User-Programmable LEDs
The 7SR46 Argus relay consists of 2 user-programmable LEDs which can be configured to protection functions
and miscellaneous functions. The LEDs (L2, L3) are programmed to be illuminated as RED.
User-Programmable LED Configuration
The 2 user-programmable LEDs are assigned to any functions by navigating OUTPUT CONFIG > OUTPUT
MATRIX menu.
