PROPER USE AND SAFETY REQUIREMENTS
Cut all the power when connecting and disconnecting the device
to a panel.
Do not clean the device with a solvent or similar material. Only
use a dry cloth.
Please do not intervene to the device when a technical problem is
encountered and get in contact with a technical service within the
shortest time.
If the warnings are not taken into account, our company or the
authorized dealer shall not be held responsible for the negative
consequences.
Do not dispose in the trash, the device must be delivered to the
collection centers (electronic device recycling centers). It should
be recycled or disposed of without harming human health and
environment.
The installation, assembly, activation and operation of the device
should be done and used by only expert professionals and in
accordance with safety regulations and instructions.
The device operates with current transformers. Do not strictly
leave current transformer tips unattached. Dangerous high voltage
can occur.

1.INTRODUCTION
1.1 Netvar Display Module Front Panel View
1) LCD Display: All powers, ratios, values, warnings and menu parameters are
monitored on the display. In the operation mode, if no key is pressed for about 5
minutes, the illumination of the screen is automatically turned off. In this case, it
will be sufficient for the user to press any key to illuminate the screen again.
2) Program Key: It enables menu entry and switching to a sub-menu.
3) ESC Key: It allows to return to a previous operation in the menu and to leave
the menu.
4) Up OK Key: It allows upward movement on the operation screen and menu.
5) Down OK Key: It allows downward movement on the work screen and menu.
6) Right OK Key: It allows movement in the right direction on the work screen.
7) Left OK Key: It allows movement in the left direction on the work screen.
8) Energy (Power) LED: It is the LED indicated by the sign on the Leksan. This
blue colored LED lights up when the device is energized. If it is not lighting, it
means there is a problem in the supply.

Alarm LED: It is the LED that gives information to the user about the status or
problems occurring in the system. It is indicated by this red colored LED sign.
Communication LED: It is the LED indicated by the sign on the Leksan. This green
LED starts flashing during communication.
11) Capacitive LED: It is the LED indicated by the sign on the Leksan. If the total
flowing reactive energy exceeds the capacitive limit, this red LED lights up.
12) Normal LED: It is the LED indicated by the sign on the Leksan. If the total reactive
energy flowing from all phases is less than the End/Cap limits set in the relay, the green
colored normal LED lights up.
13) Inductive LED: It is the LED indicated by the sign on the Leksan. If the total flowing
reactive energy exceeds the set inductive limit, this LED lights up.
1.2 Netvar Display Module Key Functions
It performs the operations of entering the menu and submenus, and also performs
confirmation operations.
In the menu, it enables to return to a previous operation and exit the menu.
In the work screen, it enables to return to the main worksheet.
The working screen provides you to navigate through detail pages and menus.
If there are parameters, it performs the operation of increasing their numerical
values.
It allows to navigate through work screen detail pages and menus. If
parameters have numerical values, it performs the process of reducing their
numerical values.
The working screen allows navigation through the main pages and menus. It
also performs the operation of entering a submenu in the menu.
The working screen allows navigation through the main pages and menus. It
also performs the process of returning from a submenu in the menu.

1.3 Netvar Relay Module Front Panel View
Netvar Modular SVC Relay can be used without a screen due to its modular structure.
Therefore, it has many LEDs that can provide information to the user.
1) ENERGY LED: This is the LED that lights up when the device is energized. If it does not
light up, there is a problem in the supply part of the device.
2) ALARM LED: It is the LED that informs the user about the situation or problems that
occur in the system.
3) COMMUNICATION (COM) LED: It is the LED that gives communication information.
It indicates communication with the screen.
4) RUN LED: It is the LED that indicates the operation of the device. It lights up when the
device is running.
5) INDUCTIVE LED: If the total flowing reactive energy is above the specified inductive
limit, this blue LED lights up.
6) NORMAL LED: The green colored normal LED lights up if the total reactive energy
flowing from all phases is less than the End/Cap limits set in the relay.
7) CAPACITIVE LED: This red LED lights up if the total flowing reactive energy is above
the capacitive limit.
8) VOLTAGE LEDS: These are the voltage LEDs of three phases. The green color of these
LEDs informs the user that there is voltage in all 3 phases. Flashing or not lighting
indicates that there is a problem with the voltages.

9) CURRENT LEDS: These are the current LEDs of three phases. The lighting of these green
LEDs informs the user that there is current in all 3 phases. Flashing or not, indicates that there
is a problem with the currents.
10) STAGE LEDs: 12 pieces. In Leksan, it is specified to which stage each LED belongs. When
the LED is on, it is understood that the relevant stage is activated.
11) MODEM LED: It is the LED that indicates Modbus communication. It flashes during
communication.
12) EXPAND LED: When an additional step module is connected to the device, this LED lights
up.
13) GENERATOR LED: It is the LED that indicates that the system is fed through the
generator.
14) FAN LED: The Fan LED is on when the fan is active.
15) ALRM LED: It lights up when manual output is given from the device.
16) THERMIC LED: It is the LED indicating that the thermal protection is switched on.
17) SVC LEDS: Located in 3 phases. When the SVC is activated, the LED of the relevant phase
lights up.
1.4 Netvar Relay Module Key Functions
Without using the display; setup, step test and clear alarms can be done
with the FNC key.
ALARM DELETE: Performed by short pressing the FNC key twice.
SETUP: Performed by pressing the FNC key once short and then long.
STAGE RECOGNITION: It is performed by long pressing the FNC
key once.
NOTE: The key press is considered long when it exceeds 1 second, short when it does not exceed.
