Zoom in/out slider

Use the slider, or the wheel on your mouse, to zoom in and out on the Connections Graph, so you can see the overall picture or just a small area. If the graph is too large to view in the window provided for it, use the sliders at the left and/or bottom of the screen to view the correct portion of the graph.

Refresh button

This button only appears if the connections have been altered and the graph is no longer representative of the current flow of signals through the SEL-MCP3 frame. Because the flow is built dynamically based on information provided to the controller module, even a minor change to connections can create a radically different connection diagram.

Flow indicator

Shows the direction and status of a signal within the frame. Roll the mouse over the line to highlight it, and to view an information box that describes that signal. A dashed line indicates a secondary (redundant) connection. See Creating a Redundant Connection .

4

Protection status indicator

Any slot (functional block) within the frame that is involved in protecting another module, or is being protected by that other module, indicates its protection status here. Statuses are indicated by color. Color meanings are described in Frame View .

5

Input indicator

• A circle indicates a protection router source or destination. The status of that item is indicated by the color of the line emanating from that circle (as in alarms)
• Color bars indicate a test signal generator from the controller module

6

Service menu

The drop-down menu has options to show all services, or to show a single service, as defined in the Connection Manager. See the figure below.

7

Module

The box size of a module is based on the number of connections it has.
