Energy (advanced metering only)
This screen displays the aggregate energy flow through
the breaker. The value of energy displayed depends on
how the trip unit was configured in the SETUP mode
(reference the Power Direction section on page 22). A
DOWN Arrow represents current flowing from Line to
Load. An UP Arrow represents current flowing from
Load to Line - reverse fed). Energy is continuously
accumulated while the breaker is energized. The value
displayed can be reset with a Modbus command.
Display values range from 0 to 999 kWh or from 1.00
to 999 MWh. When 999MWh is exceeded, the display
reverts back to 0 kWh. A counter is available via the
Modbus communications port that will indicate if the
display has exceeded the 999MWh value.
Frequency (advanced metering only)
The frequency screen displays the system frequency
as measured by the trip unit. The frequency is
displayed in Hertz.
Power Factor (advanced metering only)
The power factor screen displays the system power
factor as measured by the trip unit. The power factor is
displayed as a percentage.
Settings Mode
Spectra microEntelliGuard TM breakers include a settings
mode. This mode allows convenient review of the
breaker settings without moving through all of the
setup screens.
Setting Status
The setting status screen displays the pickup and delay
settings for short time, long time, and instantaneous
protections in a tabular format. It is normal to see dashes
where a particular setting does not apply. An example of a
non-applicable setting is instantaneous delay.
Pickup Status
Pickup status blinks the word pickup if the breaker has
detected a fault but not yet tripped. If the system load
decreases before the trip occurs this screen will return
to only the top line of the screen and stop blinking.
Error Status
The error status screen will display any error that has
been detected by the system. The errors are defined in
appendix E of this document.
Version
The version screen displays the software version
and build date. This information may be required if
a problem is encountered in the system and phone
support is necessary.
Comm Settings
The communication settings display the baud rate and
parity setting that have been selected for
communication. If either of these values do not match
the communication host, communication with the unit
will not be possible.
Events Mode
Spectra microEntelliGuard TM breakers include an event
queue. This queue allows review of the last 10 trips that
have happened on the system. The first event, called
Event 1, is the most recent event . The tenth event is the
oldest event in the memory. Each event will display the
trip type, phase, count, and level of fault that caused
the trip. The event log can be cleared of all trip events
by simultaneously pressing the up and down buttons.
