Project: Insert a Relay Coil and Child Contact


Completion Time:  15 Minutes



        Inserting Schematic Symbols


Objective:  In this exercise you insert a selector switch, relay coil, and contact using the schematic symbol icon menu. You add information to the symbols using various copying and searching techniques to take advantage of existing data.

        > Insert a selector switch, copying description lines, and searching the project for catalog information.

        > Insert a relay coil, searching the drawing for catalog information.

        > Edit the relay coil attribute locations.

        > Insert a relay contact and link the child contact to the parent coil.




1:  If the Project Manager is not displayed, on the Project tab, Project Tools panel, click Manager.
