Figure 294: Autoreclose manual close logic
The close logic uses the status of each breaker to determine whether the terminal is
closed. For single breaker applications, it is necessary to monitor the closed status of the
particular breaker. For dual breaker applications, the logic checks that either or both
breakers are closed and not out-of-service. Alternately, a user-defined setting is available
to generate this signal.
