4.5 Battery for Trip Indication

Beneath the front panel communications port lays a receptacle for a
lithium disc-style battery. The battery is used when there's a control
power failure to latch the FP-5000 trip state and to operate the front
panel trip LED. The FP-5000 can last 72 hours in this state on a
completely charged lithium battery. When the FP-5000 is energized,
the trip latch and LED indicators are powered by system power,
preserving the batteries capacity.
A defective or discharged battery causes the loss of trip state visual
LED indication during power loss conditions. A "Battery Test" button
and a green "Battery Test Indicator" indicating LED are provided
next to the lithium battery receptacle. Standard periodic mainte-
nance should include pressing the Battery Test Button and noting
that the "Battery Test Indicator" LED turns on, showing adequate
operating capacity in the battery. Battery failure will not effect relay
memory. The battery is for LED indication only.
See Section 2.6 Startup for initiating the battery into service
and Section 11 for battery maintenance.

4.6 Display Modes

If System Voltage ("VT Connect") is set to a "Wye" Configuration:
The default display screen will display the 3-phase voltages as line-
neutral (L-N) voltages. The line-line (L-L) voltages can be viewed by
going to the Monitor Mode selection screen and selecting "Load,"
then page down through the menu screen until the top line shows
the "RMS L-L Voltages." The "RMS L-N Voltages" are shown on the
next screen following the L-L voltages.
All parameters shown in (L-L) and (L-N) values in
a "Wye" voltage ct configuration are:
• The rms System Voltages
• rms Average Voltages
• %THD
• Magnitude THD
• Voltage Phasors, Minimum and Maximum System Voltages
Effective June, 2001
If System Voltage ("VT Connect") is set to a "Delta" Configuration:
The default display screen will display the 3-phase voltages as line-
line (L-L) voltages only. All other parameters will only be displayed
in (L-L) values.
In addition to the default display screen and the display "sleep
mode," there are eight FP-5000 display modes, each associated
with a pushbutton on the front panel. The modes are Monitor,
View Settings, Log, Status/Control, Set, Test, Reset and Close –
Open Breaker. The Set and Test mode entry are restricted via a
latched cover and password. The other modes are freely accessed
and cannot change or cause operation of the relay.
4.6.1 Monitor
The Monitor Mode is entered by pushing the
"Monitor" pushbutton, which allows the user to
view metered quantities (See Display 4.3). Note
the possible selections are only viewable three
lines at a time. The red LED in the upper left-
hand portion of the pushbutton area will
illuminate while the user is in the Monitor Mode.

Select one of the menu selections using the Up/Down or PgUp/
PgDown pushbuttons and press the Enter pushbutton. This will
enter you into the metering sub-menus to view any of the monitor
displays of interest using the Up/Down, PgUp, or PgDown
pushbuttons. Each box in the table shows one of the screens the
user may select. The bullets below show all available monitoring
data screens. Use the "Previous" pushbutton to return to the
Metering Main in order to select another category of data screen.
The Metering Main menu provides easy access to the most
common metering values. See the following:
• Current
• Voltage
• Power
• Energy
• Demand
• Power Factor
• Frequency
• THD
All values display the most recent measured and computed values
of each system parameter. All the metering display information is
also accessible through the communication port, which is described
in detail in Section 10 Data Communications.
