Automation control
This section outlines the control elements used for automation.
Front panel status and control
There can be a maximum of six breakers and 6 disconnect switches (referred to as devices)
plus autoreclose and local-remote status and control. All devices have a short name
setting and a full name setting. The short name is used to designate the device and the
associated select pushbutton.
The top-level control screen presents the status of each enabled breaker and disconnect.
The status of the local-remote function and the autoreclose function is shown if these
functions are enabled. All devices are displayed in grey.
If the pushbutton control setting is enabled for a device or function, then the pushbutton
on the front panel interface is assigned as shown in the figure. A device that does not have
pushbutton control enabled does not have a pushbutton on this screen.
