AUTORECLOSE OPERATION

The Autoreclose function is a complex function consisting of several modules interacting with one another. This is
described in terms of separate logic diagrams, which link together by means of Internal signals (depicted by the
pink-coloured boxes. To help you with the analysis of the various Autoreclose modules, the following table
describes how these internal signals link up in the various logic diagrams. Each internal signal is allocated with an
ID, and the diagrams on which they appear are also identified.
