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.

EXAMPLE PROTECTION STAGE
Figure 3.2.2.2-8 AQ-200 series IED stage navigation and modification.
Each protection stage and supportive function has five stage menus Info, Settings,
Registers, IO and Events.

Instuction manual –AQ F205 Feeder protection IED 15 (404)
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.

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.

Instuction manual –AQ F205 Feeder protection IED 18 (404)
Figure 3.2.2.2-12 AQ-200 series IED stage information is divided into two sections.
Starting and tripping signals of protection stages are connected to physical outputs in Direct
Output Control menu. It is possible to connect to output relay or to start- trip- or user
configurable LED. In case when stage is internally blocked (DI or other signal) it is possible
to configure an output to indicate that stage is blocked. Connection to outputs can be either
latched |x| or non-latched x.
Stage blocking is done in Blocking Input Control menu. Blocking can be done by using
digital inputs, logical inputs or outputs, stage start- trip- or blocked information or by using
object status information.

Instuction manual –AQ F205 Feeder protection IED 19 (404)

active setting group 1…8.
It is possible to activate desired setting group
by setting the force SG. While doing this
Force SG change has to be enabled.
In Used setting groups menus it is possible
to activate setting groups between 1 and
1…8 (default only 1 group is active).
Select local control for different setting
groups from SG Local Select. Digital inputs,
Logical inputs or outputs, stage starting-
tripping- or blocking, RTDs and object status
information can be used.

off as default). Only masked events appear
to event list. Events cannot be cleared.
Figure 3.2.2.3-16 Setting Groups menu displays all the information related to group
changing.
Setting group 1 has the highest and group 8 the lowest priority. Setting groups can be
controlled with steady signal or pulses.
