2GENERAL
The AQ-F215 Feeder Protection IED is a member of the AQ-200 product line. The AQ-200
protection product line in respect of hardware and software is a modular concept. The
hardware modules are assembled and configured according to the application IO
requirements and the software determines the available functions. This manual describes
the specific application of the AQ-F215 Feeder Protection IED. For other AQ-200 series
products please consult corresponding device manuals.

3IED USER INTERFACE
AQ 200 series IED user interface section is divided into hardware- and software user
interface sections. Software interface is divided into local panel configuration and
programming by using AQtivate 200 freeware software suite.
3.1 AQ 200 SERIES LOCAL PANEL STRUCTURE
AQ 200 series IED have multiple LEDs, control buttons and local RJ-45 Ethernet port for
configuration on front as a default. On rear each unit is equipped with RS-485 serial
interface and RJ-45 Ethernet interface options as a standard. See list below.
4 default LEDs for free configuration: Power,
Error, Start and Trip.
16 freely configurable LEDs with
programmable legend texts.
3 object control buttons: Choose the
controllable object with Ctrl –button, control
breaker with 0- and I push buttons.
L/R push button for local remote control.
7 Navigation buttons for IED local
programming and a button for password
activation.
RJ-45 Ethernet port for IED configuration.

3.2 IED PROGRAMMING
3.2.1 BASIC CONFIGURATION
IED user interface is divided into 5 quick displays. The displays are Events, Favorites,
Mimic, LEDs and Clock. Default quick display is the mimic view and it is possible to glance
through these menus by pressing arrows left and right. Please note that the available quick
display carousel views might be different if user has changed it with AQtivate setting tools

Moving around in the five main quick displays is done by pressing navigation keys
to left and right “ ”.
Home button “ ” transfers the user between the quick displays and six main
configuration menus.
Moving around in main configuration menus is done by pressing navigation buttons
“ ” and entering menu is confirmed by pressing enter “
”. Notice that name of the main menu appears to the bottom of the display while
staying on top of icon.

Instruction manual –AQ F215 Feeder Protection IED 13 (424)
Cancel key “ ” takes you one step back or holding it down for 3 seconds takes
you back to general –menu “ ”.Cancel key is also used for alarm LEDs reset.
Padlock button “ ” takes user to password menu where it is possible to enter
different user levels (user, operator, configurator and super user).
3.2.2 NAVIGATION IN MAIN CONFIGURATION MENUS
All the settings in AQ-200 series IEDs have been divided into main configuration menus.
Main configuration menus are presented below. Available menus may vary according to
IED type.

according IED type.
Stage activation

Instruction manual –AQ F215 Feeder Protection IED 17 (424)
Activation of different protection stages is
done in Stage activation –sub menu. Each
protection stage and supporting function is
disabled as standard.
Activated menus will appear below the stage
specific sub-menu for example I> appears
below Current –module, U< appears below
Voltage-module etc.

Each protection stage and supportive function has five stage menus Info, Settings,
Registers, IO and Events.
INFO-menu

Instruction manual –AQ F215 Feeder Protection IED 18 (424)
Function is activated and disabled in Stage
activation menu. It is possible to disable
function in Info menu as well.
Function condition indicates whether the
stages condition is Normal, Start or Trip.
Measured amplitude can be Peak-to-peak,
TRMS or RMS. As a default it is set as RMS.
Available measured amplitudes vary.
Under Characteristic graphs-title you can
open graphs related to the protection
function.
Info view has calculator for function starts,
trips and blockings. It is possible to clear
calculators by choosing Clear statistics and
Clear.
Measurements display measurements
relevant for the function.
Active setting group and its settings are all
visible in Info menu. Other setting groups can
be set in the SETTINGS-menu.

REGISTERS-menu
Figure 3.2.2.2-11 AQ-200 series IED stage information is divided into two sections.
Specific fault data of IEDs is stored in operation log under the register. Each of these 12
logs includes pre-fault current, fault current, time stamp and active group during the
triggering. Operation log can be cleared by choosing Clear registers Clear.
Events generated by the specific stage can be checked by going to Stage event register.
General events cannot be cleared.
