What action does the Digital Control System take when the maximum number of log entries is reached on the BEAR Power Unit?

When the maximum number of log entries is reached on the BEAR Power Unit, the Digital Control System automatically overwrites old entries. This action ensures that the system continues to function smoothly and maintain the ongoing logging of new data without interruption. By overwriting the oldest log entries, the system manages its storage capacity efficiently, providing a continuous record of the most current and relevant information while discarding outdated data that is no longer needed. This method helps in maximizing available space and keeping the system current, which is vital for effective monitoring and control operations.
