BE1-25A Functional Description

9146600990 Rev M

A functional block diagram of the Auto-Synchronizer is given in Figure 3-2, and is referred to in the circuit
descriptions that follow.  A black box approach is taken, with the emphasis on the inputs and outputs to the
external world.  Omitted from the diagram are the internal signals that communicate between the various
modules of the system.  Note that the output relays shown in the lower right corner of the figure are not
present unless the controlling options are installed.

Later in this section, additional functional diagrams are provided that describe the options.
