Figure 2.3.16-2. Example sequence of two shots. After shot 2 the fault is
cleared.

starts.
2. After the start delay, an OpenCB relay output closes.
3. A CB opens. The dead time from shot 1 starts, and the
OpenCB relay output opens.
4. The dead time from shot 1 runs out; a CloseCB output
relay closes.
