Section 4: 7SR22 Configuration

4.1 Logic Configuration

Our application is to employ a current check using the pickup of an Instantaneous Overcurrent Element (50-
1) to qualify an Arc Sensor operation. The following sections outline the logic implemented.

4.2 User output Allocation

Using the previously defined ARC Fault Sensor Zones we will nominate the User Outputs that will capture
the resultant SARC operation and current check logic.
