2GENERAL
The AQ-F205 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-F205 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. Home button transfers the user
between quick displays and 6 main configuration menus. Main configuration menus are

General, Protection, Control, Communication, Measurements and Monitoring. You can
choose the main menu by using the four arrow keys and press enter.
Figure 3.2.1-2 AQ-200 series IED basic navigation.
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.

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 six main configuration menus.
Main configuration menus are presented below.
