The AQ-S254 alarm and indication unit is a member of the AQ-200 product line. The hardware and
software are modular: the hardware modules are assembled and con^gured according to the
application's I/O requirements and the software determines the available functions. This manual
describes the speci^c application of the AQ-S254 alarm and indication unit. For other AQ-200 series
products please consult their respective device manuals.
AQ-S254 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 display and event list. There are up to fourteen
(14) option card slots available for additional I/O or communication cards for more comprehensive
monitoring and control applications. AQ-S254 can be connected to a substation automation system by
using various standard communication protocols, including the IEC 61850 substation communication
standard.

The user interface section of an AQ-200 series device is divided into two user interface sections: one
for the hardware and the other for the software. You can access the software interface either through
the front panel or through the AQtivate freeware software suite.

The front panel of AQ-250 series devices have multiple LEDs, control buttons and a local RJ-45
Ethernet port for con^guration. 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. 4.1.1 - 1. Local panel structure.
1. Four (4) default LEDs: "Power", "Error", "Start" (con^gurable) and "Trip" (con^gurable).
2. Sixteen (16) freely con^gurable LEDs (red, orange, green) with programmable legend texts.
3. Three (3) object control buttons: Choose the controllable object with the CtrlCtrl button and
control the breaker or other object with the II and the OO buttons.
4. The L/RL/R button switches between the local and the remote control modes.
5. Eight (8) buttons for IED local programming: the four navigation arrows, the ackack and the OKOK
buttons, the HomeHome and the password activation buttons).
6. Twelve (12) freely con^gurable function buttons (F1…F12). Each button has a freely
con^gurable LED (red, orange, green).
7. One (1) RJ-45 Ethernet port for IED con^guration.
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 con^gurable LEDs are located on the left side of the display. Their activation and
color (green, orange, red) are based on the settings the user has put in place in the software.
The view in the screen is freely con^gurable. Virtual switches and buttons can be added which can be
used to change the setting groups or control the relay's general logic locally or remotely. The status of
the object (circuit breaker, disconnector) can be displayed on the screen. All measured and calculated
values regardless of the magnitude catecory (current, voltage, power, energy, frequency, etc.) can be
shown on the screen.
Holding the II (object control) button down for ^ve seconds brings up the 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 buttons are marked as having been tested, the device will return back to the default view.

As a factory default, no user level is locked with a password in an IED. In order to activate the different
user levels, click the LLockock button in the device's HMI and set the desired passwords for the different
user levels.
NONOTE!TE!
Passwords can only be set locally in an HMI.
A number of stars are displayed in the upper right corner of the HMI; these indicate the current user
level. The different user levels and their star indicators are as follows (also, see the image below for the
HMI view):
• Super user (***)
• Con^gurator (**)
• Operator (*)
• User ( - )

You can set a new password for a user level by selecting the key icon next to the user level's name.
After this you can lock the user level by pressing the RReetturnurn key while the lock is selected. If you need
to change the password, you can select the key icon again and give a new password. Please note that
in order to do this the user level whose password is being changed must be unlocked.
As mentioned above, the access level of the different user levels is indicated by the number of stars.
The required access level to change a parameter is indicated with a star (*) symbol if such is required.
As a general rule the access levels are divided as follows:
• User: Can view any menus and settings but cannot change any settings, nor operate
breakers or other equipment.
• Operator: Can view any menus and settings but cannot change any settings UT can
operate breakers and other equipment.
• Con^gurator: Can change most settings such as basic protection pick-up levels or time
delays, breaker control functions, signal descriptions etc. and can operate breakers
and other equipment.
• Super user: Can change any setting and can operate breakers and other equipment.
NONOTE!TE!
In AQ-250 frame units unlocking and locking a user level generates a time-stamped event to
the event log.
NONOTE!TE!
Any user level with a password automatically locks itself after half an hour (30 minutes) of
inactivity.

Signal alarming is the main feature of AQ-S254 Alarming IEDs. The alarming unit has 128 alarms the
user can set. The user de^nes each alarm description and activating signal. These settings are done in
the Alarm settings menu ( Control → Device I/O → Alarm settings ).
The alarming unit generates events with time stamps into the event history and the alarm statuses are
shown on the IED's display. The alarm statuses can also be read in the remote terminal unit (RTU).

Figure. 5.1 - 5. Digital inputs assigned as alarm activating signals.
The user can assign signals into alarms by clicking on the matrix. When the matrix is done, it must be
sent to the relay for the changes to take effect ( Commands → Write to relay → Logic ).
When the signal assigned into an alarm activates, the color changes in the Alarms view in the relay's
HMI. Active alarms are displayed in the Alarms view with a red color in the text box. When the signal
that activated the alarm is deactivated, the alarm box color becomes yellow until the alarm has been
reset. Once an alarm has been reset the color changes back to gray.
If the alarm signal's ON state has been checked in the Event Mask , an ALARM ON event is recorded
with a time stamp into the event history. These alarms are also reported in the communication
protocol if one is in use.
