3.12 Binary Outputs

The 7SR45 Argus Relay consists of 2 or 4 binary output which can be configured to send commands to the
switchgear units and annunciations for remote signalling of the important events and status.

Binary Output Matrix

Binary output can be assigned to any available functions under OUTPUT CONFIG > OUTPUT MATRIX menu.

Binary Output Configuration

In the default mode of operation, binary outputs are self reset and remain energised until the triggering condition
exists. If required, the binary outputs can be programmed to operate as 'hand reset'.
NOTE:
The binary output 1 and binary output 2 only can be configured as hand reset. The binary output 3 and binary
output 4 are always of self reset type. The minimum operating time is 20 milliseconds.

Self Reset/Hand Reset
In the default operating mode, binary outputs are self reset. If required, the outputs can be programmed to
operate as 'hand reset'. However, the hand reset functionality is applicable for protection trip signals, IRF signal,
and BI signals only.
All the supervisory signals such as low battery, general pick up, and protection healthy are always of self reset
type.
By default, the Binary Output 1 is mapped to IRF function and programmed as 'hand reset". In the self reset
condition, binary output resets if the input current drops below the sensitivity levels.
NOTE:
In the absence of auxiliary voltage, the binary output 3 and binary output 4 will not be functional and remain in
the non-operated condition.
