This option allows you to create a single line diagram for a PDB that you select in the Electrical Index. You start by selecting the PDB for which you want to generate an SLD. Then, you define the generation options such as the page settings and the settings for the display of the circuits and circuit components. After generating the SLD, you can save the SLD as an internal drawing in the software. Note that you can generate only one SLD per PDB. If you select a PDB for which you have previously created an SLD, the software opens the existing SLD using the generation options that you defined before the previous generation. To generate a completely new SLD for such a PDB, first delete the SLD from the Documents folder in the Electrical Index and then generate the SLD.
-
In the Electrical Index, select the power distribution board for which you want to generate a single line diagram.
-
To open the Single Line Diagram Options dialog, select Actions > Generate SLD for PDB
. Alternately, you can right-click a highlighted item and select Generate SLD.
-
On the Single Line Diagram Options dialog, define the SLD generation options as you require. For details, see Single Line Diagram Options Dialog.
You can define the required properties for the newly generated drawing on the Document Properties tab of the Single Line Diagram Options dialog. This tab is available for all unsaved new SLDs that have not been created
manually. See Document Properties Tab (Single Line Diagram Options Dialog).
If you are generating an SLD with multiple sheets, in order to balance the scaling
of the graphics on all the sheets in the drawing, you can control the display of coupled
buses. It is possible to place couple buses on a single drawing sheet or split the
display of the coupled buses between two drawing sheets.
-
On the Bus tab of the Single Line Diagram Options, do one of the following under Display options:
-
Clear the Retain the display of coupled buses on the same sheet check box to split the display of coupled buses and display them on two drawing sheets (recommended).
-
Select Retain the display of coupled buses on the same sheet check box to keep the display of coupled buses on the same drawing sheet (some of the drawing sheets may appear congested while others may have a lot of empty space).
-
-
Select Generate.
-
To save the drawing as an internal document, in the generated SLD drawing, select File > Save.
-
If there are overlapping connectors on the generated drawing, open the SLD and then select Tools > Optimize Overlapping Connectors to reposition the connectors so that they do not overlap. Note that this operation may take a few moments if your SLD contains a lot of connectors.
-
For information on how to use custom symbols in your SLDs and the SLD legends, see Associate Custom Symbols with Plant Items.
-
To include junction boxes and local panels in the drawing, set the IS LOAD property of that junction box or local panel to TRUE. Alternatively, you can select the Consumer check box on the Electrical Data tab of the Common Properties dialog. Consequently, the software will treat these items as any other loads in the generated drawing and they will behave according to the drawing option settings that have been defined for them.
-
If, during the SLD generation, the software cannot find a referenced symbol for a specific electrical item, the software uses the default symbol file (default.sym) to represent the item. You specify default files in Options Manager.
-
Sometimes, after the software opens a drawing, the distance between connected items is either too long or too short, which results in an inappropriate display of connectors. To control the visual consistency of connectors, you can set a Clearance value that specifies the amount of space that the software will maintain between the connector and the connected element (also known as range avoidance). This action allows you to control the visual consistency of connectors that make right-angle turns just before they attach to a symbol.
-
To set Clearance, select a connector and then type the minimum distance from the symbols where you would like the first turn in the connectors to occur. Note that the default setting is zero.
