All contacts in Figure 6 are shown as they would be with the NLR relay in its RESET position and no fault on the line. Cam-operated contacts SCl, SC3, and SR3 are held closed by a cam lobe and will open on the first step of the stepping switch, while SC2 is held open and will close on the first step. Contacts RSl and RS2 are held in the positions shown by a cam lobe, but will not change positions until the switch steps the second time.
