4. IED user interface
4.1. Panel structure
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.
4.1.1. Local panel structure
The front panel of AQ-200 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.
Four (4) default LEDs: "Power", "Error", "Start" (congurable) and "Trip" (congurable).
Sixteen (16) freely congurable LEDs with programmable legend texts.
Three (3) object control buttons: Choose the controllable object with the Ctrl buttonand the
control breaker with the I and Obuttons.
The L/R button switches between the local and the remote control modes.
Eight (8) buttons for IED local programming:the four navigation arrows and the Enter button in
the middle, as well as the Home, theBack and the password activation buttons.
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 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.

Figure. 4.4. - 11. I/O.
The "I/O" section is divided into two subsections: "Direct output control" and "Blocking input control".
In "Direct output control" you can connect the stage's starting and tripping signals to physical outputs,
either to an output relay or an LED (which can be congured with START orTRIP signals, or by the
user). If the stage is blocked internally (DI or another signal), you can congure an output to indicate
the stage that is blocked. A connection to an output can be either latched ("|x|") or non-latched ("x").
"Blocking input control" allows you to block stages. The blocking can be done by using any of the
following:
digital inputs
logical inputs or outputs
the START, TRIPor BLOCKEDinformation of the stage
object status information.
