Breaker Hardware One-Line Diagram
A one-line diagram of the breaker hardware configuration can be displayed on the front panel. This
diagram changes in real time to reflect the current state of the configured breakers. The breaker hardware
one-line diagram is disabled by default. To display the breaker hardware one-line diagram using front
panel controls, navigate to Settings > General Settings > Front Panel HMI > One-Line Diagram and
enable the setting. If using BESTCOMSPlus, navigate to Settings Explorer, General Settings, Front Panel
HMI and select Enable on the One-Line Diagram setting.
Once enabled, the one-line diagram appears on both the front panel Summary and Main Menu screens.
The One-Line Diagram Menu screen provides metering for mains fail transfer, generator and bus
parameters as well as breaker controls. To reach the One-Line Diagram Menu screen, go to the Main
Menu and select the one-line diagram as you would a normal menu option and press the right arrow
pushbutton. The one-line diagram, mains fail transfer state (if enabled), generator and bus parameters,
and breaker controls are displayed respectively from the top of the menu.
Further mains fail transfer state metering is available by selecting the “MAINSFAIL XFER STATE” and
pressing the right arrow pushbutton. Mains fail transfer state, transfer delay, return delay, max transfer
time, max parallel time, and open transition delay are displayed.
To issue a breaker open or breaker close command, select the appropriate menu option, press Edit and
select ON.
The ONE-LINE DIAGRAM screen options are shown in Figure 2-4. Figure 2-5, below, illustrates and
describes the different configurations of the one-line diagram.
