Removing a Ground from a Device
You can only remove a ground from the device or conductor on which the grounding was applied. To remove a ground from a device, complete these steps:
1. Open a Viewer window and load the map that contains the grounded device.
2. Open the Control Tool for the device.
3. Click on the Ground... button and select Remove Ground from the drop-down list. If the device has multiple grounds, a Select Secondary Object dialog box appears.
4. Click on the conductor attached to the device on the side with the ground you want to remove. The alias of that conductor appears in the dialog box.
5. Click OK. The grounding symbol is removed from the Viewer.
Note: When removing the last ground on a device that is required by an Issued safety document, a Grounds Check dialog box will be displayed. From the Grounds Check dialog box you have the option of navigating to the Safety Document, continuing with the Remove Ground operation or canceling the operation. For more details, see Grounds Check on page 11-116.
Disabling Automatic Throwover (ATO) Switches
The Control Tool for a Primary or Secondary ATO switch provides a function to disable or enable ATO functions. Disabling either ATO switch prevents the system from automatically throwing-over or auto-returning the pair of switches.
