2. General
TheNPS914alarm and indicationrelayisamember oftheNP900productline.Thehardwareand software
are modular: the hardware modules are assembled and configured according to the application's I/O
requirements and the software determines the available functions. This manual describes the specific
applicationoftheNPS914alarm and indicationrelay.ForotherNP900series products please consult their
respective devicemanuals.
NPS914 may be applied as a substation alarm sounder, a substation general I/O extension unit or in any
other application that requires extended I/O capabilities. The local indications are visualized conveniently
through the freely programmable alarm LED display and event list. Up to six (6) optional I/ O or
communication cards are available for extensive monitoring and control applications. NPS914 can be
connected to a substation automation system by using various standard communication protocols,
including the IEC 61850 substation communication standard.

3. IED user interface
3.1. Panel structure
The user interface section of an NP900 series device is divided into two user interface sections: one for the
hardwareandtheotherforthesoftware.Youcanaccessthesoftwareinterfaceeitherthrough the front panel
or through the SMART9 freeware software suite.
3.1.1. Local panel structure
The front panel of NP900 series devices have multiple LEDs, control buttons and a local RJ-45 Ethernet
port for configuration. Each unit is also equipped with an RS-485 serial interface and an RJ-45 Ethernet
interface on the back of the device. See the image and list below.
Figure. 3.1.1. - 1. Local panel structure.
1. Four(4)defaultLEDs:"Power","Error", "Start"(configurable)and"Trip"(configurable).
2. Sixteen (16) freely configurable LEDs with programmable legend texts.
3. Three(3) objectcontrol buttons:Choose thecontrollable objectwith the Ctrl buttonand operatethe
control breaker with the I and O buttons.
4. The L/R button switches between the local and the remote control modes.
5. Eight(8)buttonsforIED local programming:the fournavigationarrows andthe Enter button in the
middle, as well as the Home, the Back and the password activation buttons.
6. One (1) RJ-45 Ethernet port for IEDconfiguration.
When the unit is powered on, the green "Power" LED is lit. When the red "Error" LED is lit, the relay has an
internal (hardware or software) error that affects the operation of the unit. The activation of the yellow
"Start" LED and the red "Trip" LED are based on the setting the user has put in place in the software.
The sixteen freely configurable LEDs are located on the right side of the display. Their activation and color

(green or yellow) are based on the settings the user has put in place in the software.
Holding the I (object control) button down for five seconds brings upthe button test menu. It displays all the
physical buttons on the front panel. Pressing any of the listed buttons marks them as tested. When all
buttonsare markedas having been tested,you canpress the Back buttonto closethe button test menu.
3.2. Mimic and main menu
3.2.1. Basic configuration
The user interface is dividedintoseven(7)quick displays:"Events","Favorites","Measurements", "Mimic",
"LEDs","Clock"and"Faultregister".Thedefaultquickdisplay(aspresentedintheimage below) is the mimic
view; you can move through these menus by pressing the left and right arrow buttons. Please note that the
available quick display carousel view might be different if you have changed the view with SMART9's
Carousel Designer tool.
Figure. 3.2.1. - 2. Basic navigation (general).
The Home button switches between the quick display carousel and the main display with the six (6) main
configuration menus (General, Protection, Control, Communication, Measurements and Monitoring). Note
that the available menus vary depending on the device type. You can select one of the menus by using the four
navigation arrows and pressing Enter in the middle. The Back buttontakes you back one step. If you hold it down
for three seconds, it takes you back to the General menu. YoucanalsouseittoresetthealarmLEDsyouhaveset.
The password activation button (with the padlock icon) takes you to the password menu where you can enter the
passwordsforthevarioususerlevels (User, Operator, Configurator, and Super-user).

3.4. Control menu
Main menu
The Control main menu includes submenus (see the image below) for enabling the various control
functions and objects (Controls enabled), enabling and controlling the setting groups (Setting groups),
configuring the objects (Objects), setting the various control functions (Control functions) and configuring
the inputs and outputs (Device I/O). The available control functions depend on the model of the device in
use.
Controls enabled
Figure. 3.4. - 7. Controls enabled submenu.
You can activate the selected control functions in the Controls enabled submenu. By default all the control
functions are disabled. All activated functions can be viewed in the Control functions submenu (see the
section "Control functions" below for more information).
In this submenu you can also activate and disable the controllable objects. As with control functions, all

objects are disabled by default. All activated objects can be viewed in the Objects submenu (see the
section "Objects" below for moreinformation).
Setting groups
Figure. 3.4. - 8. Setting groups submenu.
The Setting groups submenu displays all the information related to setting group changing, such as the
following:
• Active setting group: displays the currentactive setting group (SG1…SG8).

APPLICATION CONTROL
Figure. 3.4. - 12. Application control section.
You can connect object statuses directly to physical outputs in the "Signal connections" subsection
(Control → Application control). They can be connected to output relays, as well as to user- configurable
LEDs. A connection to an output can be either latched ("|x|") or non-latched ("x").
Object blocking is done in the "Blocking input control" subsection. It can be done by any of the following:
digitalinputs,logicalinputsoroutputs,objectstatusinformationaswellasstagestarts,trips or blocks.
