Table 6-1 shows the battery profile parameter data and the status of the operations performed on the battery
power.
Table 6-1 Battery Profile Parameters
Battery Profile Parameter Description Unit
Device ON Dur’n The duration of the device powered on with the battery source
only.
Seconds
Backlit ON Dur’n The duration of the LCD backlight powered on with the battery
source only.
Seconds
BO Oper’n Count The number of times the binary outputs operate with the battery
source only.
-
BI Oper’n Count The number of times the binary inputs operate with the battery
source only.
-
The battery profile parameters data can be cleared with the DATA STORAGE > Clr Battery Data setting
in the HMI.
NOTE
When replacing the battery, clear the battery profile parameters data in the HMI.
Sleep Mode
The 7SR45 Argus Relay goes into sleep mode when the auxiliary power/CT power, and USB power are not
available. When the relay is in sleep mode, you can access the LCD by pressing the BAT ON/OFF key. In case
of inactivity, the relay goes to the sleep mode after 60 s.
When the relay is powered using CT power and auxiliary power is not available, if any fault occurs in the
system and the phase CT currents are disconnected, the relay goes to the sleep mode automatically.
If the relay is powered on via USB power mode and the USB cable is removed, then the relay goes to the sleep
mode automatically.
NOTE
During the sleep mode, the 7SR45 Argus Relay has limited functionality.
Low Battery Status Indication
The LOW BATTERY LED indication is displayed when the battery voltage falls below the sufficient operating
voltage and an event is generated. In the low battery condition, the view/edit setting is only allowed.
In the low battery mode, the backlight does not turn on.
The LOW BATTERY indication can be mapped to a binary output and can be used for the remote signaling.
