This dialog allows you to define pairs of equipment items that can be connected in parallel. You can then place these pairs on cable block diagrams and they will appear as connected in parallel.
The definition of a parallel relationship between items is subject to certain rules. See Rules Governing Parallel Relations.
To open this dialog, select on the Actions toolbar or select Actions > Manage Parallel Equipment. The dialog options are as follows:
Show parallel equipment data
Enables you to filter the data that is displayed in the Parallel equipment definition section of the dialog.
Show all existing parallel pairs
Shows all the existing parallel equipment items that have been defined as pairs in the current plant.
Parallel pairs placed on the current cable block diagram only
Shows only those paired equipment items that have been placed on the current cable block diagram.
Parallel pairs not placed on any cable block diagram
Shows only those paired equipment items that have not been placed on any cable block diagram.
Parallel equipment definition
Enables you define equipment items as couples so that they can be connected in parallel. To define two items as coupled or to replace one of the coupled items, choose a row and then select to find the equipment item that you require. You can then set the direction of the equipment connection (In or Out). Note that the and list arrow appear only after selecting a row.
Item 1
Selecting allows you to select the first equipment item in the current couple.
Item 2
Selecting allows you to select the second equipment item in the current couple.
Direction
Allows you to select the connection direction of the equipment: In or Out. Note that list arrow appears only after you select a particular line.
Add
Appends a new empty row to the grid, after which you can select to find an appropriate equipment item.
Remove
Removes the selected row from the grid and after selecting Apply or OK cancels the coupling of the items.

After completing the definition of the parallel pairs and opening a cable block diagram, all the parallel pairs become available in the Parallel pairs list on the Modify Connector ribbon. This ribbon becomes available after you select a cable that has been placed on a cable block diagram. See Connect Equipment Items in Parallel.
-
In the Electrical Index and Electrical Engineer, a special indicator appears next to the equipment items that are connected in parallel.
