Section 13. User Interface – HMI
Touching any of the circuit breaker symbols on
the one-line displays that circuit breaker ’s status
screen, as illustrated in Figure 13.4.
This display provides the status of the circuit
breaker, including the contact position, racking
position, secondary disconnect position, electrical
lockout status, closing spring status, and a summary
of the types of protection that are enabled for this
circuit. Current and voltage measurements are
displayed and additional metering information is
available by touching the appropriate buttons for
the optional metering parameters. It is also possible
to scroll through the circuit breaker status screens
by pressing the “Next Breaker” or “Previous
Breaker” keys.
From the circuit breaker status screen you can
also access the protection settings and predictive
maintenance data for this circuit. You will see later
how the protection settings and maintenance
data can also be accessed via the main menu,
providing more than one path to the information.
Touch the Control key to display a circuit breaker
control window, as illustrated in Figure 13.5. This
window shows the name of the breaker with its cur-
rent state (open, tripped or closed). If you want to
confirm that you are referencing the correct circuit,
you can turn on the locator LED for 10 or 30 seconds.
This causes the blue Locator LED on the corre-
sponding circuit’s Messenger to blink, providing
visual identification of the circuit breaker you are
referencing.
You can operate the breaker by touching the
appropriate button. Note that in Figure 13.5, Breaker
2 is “Open - Not Tripped” and the options available
are to close or trip the breaker. Touching the CLOSE
button displays another window asking for confir-
mation. After you confirm that this is what you want,
the circuit breaker contacts are closed. Touching
the TRIP button and again confirming this action on
the corresponding pop-up window actuates the
flux shifter and any lockouts associated with a trip.
In Figure 13.6, circuit breaker Main 2 is closed.
Touching the OPEN button opens the circuit breaker
via the shunt trip. Touching the TRIP button actuates
the flux shifter and any lockout commands. In all
cases, touching an Open, Trip or Close button dis-
plays a second window asking for confirmation of
the action.
A check box is available in all of the breaker control
screens to block other HMIs. Checking this box
prevents any other HMIs, either near-gear or
remote, from operating this circuit breaker.
