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.

During the sleep mode, the 7SR45 Argus Relay has limited functionality.

Low Battery Status Indication

6.4.7
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.
