Other figures mentioned are insome way connected or cooperate with Figure 157.Before going into details in the following chapters, the short functional/featuresummary is given below.The auto reclosing function is multi-shot capable and suitable for both high-speedand delayed auto reclosing. The function can be set to perform a single-shot, two-shot, three-shot, four-shot or five-shot reclosing sequence. Dead times for all shotscan be set independently.An auto recloser sequence can be initiated by:• protection operation• circuit breaker operation (when enabled by setting StartByCBOpen=On)At the end of the dead time, provided that other conditions are fulfilled, a circuitbreaker close command signal is given. The other conditions to be fulfilled are:Section 12 1MRK 505 394-UEN AControl328 Line differential protection RED650 2.2 IECTechnical manual
