Configuring an automatic transfer switch (ATS)

To configure an automatic transfer switch (ATS) you have added to a one-line in the Graphics Editor:

1. Edit the following properties:
   1. Exposed Properties:
      CommonBusName, MainBusName, and AuxBusName
      Set to the busbar component name that represents the buses to which the ATS is connected.
   2. Binding Conditions:
      PosOnEmergencyCond and PosOnUtilityCond
      You can leave these empty if your equipment has an item name (AtsSwMainCls or AtsSwAuxCls) set for the variable tag. You can also set the condition using a variable tag by creating a Boolean expression for the position of the ATS.

This component helps establish the connectivity by which the advanced one-line will energize buses based on connected sources.

If an ATS is configured incorrectly, use the Connection Debugger to troubleshoot the following:

• Ensure the CommonBusName, MainBusName, and AuxBusName are set.
  
• Ensure the conditions have valid Boolean expressions. For more information, see Condition attribute expressions.
