3.13 Binary Output Operations
The relay reset can be performed from the Relay Identifier Screen > TEST/RESET► key.
If the fault current persists and if the user presses TEST/RESET► key, the pop-up message appears,
"FAULT PERSISTS".
Based on the availability of power source, the flag can be reset by using any one of the following conditions:
3.13.1
BO Trip/Reset on Battery/USB
In this mode, the relay uses the power from battery/USB to operate/reset the binary output and takes
approximately 4s to perform the action.
If the consecutive commands are provided within 4 seconds, the relay performs delayed operations and displays
a pop-up message appears on the HMI "INSUFFICIENT ENERGY".
3.13.2
BO Trip/Reset on CT Input or Auxiliary Voltage
In this mode, the relay can operate/reset the binary outputs instantaneously.
