PROPER USE AND SAFETY REQUIREMENTS
Cihaz panoya bağlanırken ve panodan sökülürken tüm enerjiyi kesiniz.
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.
(See: RKR 12/18/24 current transformer connection diagram, sf:22)
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.
The common supplies of the stage terminals must be connected to any phase
with a 6 Ampere fuse separately. We absolutely do not recommend parallel
connection! When separate fuses are connected to the partners, the fuse
protection will be activated in the event of a short circuit in the contactors
over time, and only the relevant stage blocks will be deactivated, allowing the
device to continue compensation with other blocks. Otherwise (when a single
fuse is used with parallel connection), all stages will be deactivated due to a
problem occurring in one contactor!
Current transformers should be placed immediately at the output of the main
switch of the enterprise.

path 4.2.1.2. yfrom the device screen.
IMPORTANT NOTE: Each heading number in the manual also refers to the
menu numbering in the device.
Recommendations for Installation with Capacitors:
In order to get results in a shorter
time during installation with
capacitors, it is recommended to
connect capacitors to the first stages
starting with three-phase large power
capacitors and reactors to the last
stages.
If compensators (capacitor or
reactor) are placed in stages in a
complex way, without taking into
account their characteristics, it is
recommended to switch off the
supply fuses of the reactors before
installation with capacitors.
Recommendations for Installation with Reactors:
During installation with reactors, it is
recommended to connect the reactors
to the first stages, starting with the
three-phase high power reactors, and
the capacitors to the last stages, in
order to obtain results in a shorter
time.
If compensators (capacitor or reactor)
are placed in a complex way in
stages, without taking into account
their characteristics, it is
recommended to switch off the
supply fuses of the capacitors before
the installation with reactors.
The factory default installation setting is set as installation with capacitors.

We are Starting the Installation (Setup)
After the device connections are made in accordance with the connection diagram, the device is
energized.
When the device is energized, the "Serial Number" screen shown in Figure 1 appears. By pressing
the Enter Button or after 3 seconds, it automatically switches to the next screen. "Current
Transformer" screen appears as shown in Figure 2. Select the current transformer value
using the Up/Down Ok Buttons and press the Enter Button.
The device then automatically starts setup, the flashing red "Setup" LED positioned on the left
side of the device lights up steadily after the setup starts. During the setup, the device checks
the line parameters such as current control, voltage control, voltage-current matching and
current directions as shown in Figure 3 and Figure 4. If no faulty situation is encountered, the
"StupxbAsArili" text appears on the screen and the relay automatically switches to stage
recognition.
When the device automatically moves to the stage recognition test after the installation is
complete
The "Setup" LED turns off and the red " Stage Recognition" LED lights up as shown in Figure 6.

Figure 5. Stage LEDs at the top of the device showing the status of the stages
The stage recognition process as shown in Figure 7 continues with the display of each
recognized stage value on the screen, while the information of which stage is activated can be
followed from the green colored Stage LEDs bar at the top of the device as shown in Figure 5,
and after the recognition process of the last stage is completed, the "Stage Recognition" LED
turns off and the green "Compensate" LED lights up. The device now starts to compensate with
the stages it recognizes.
If the compensator connected to the recognized stage is a capacitor, the capacitive red LED on
the left side of the device (as in Figure 7) and if it is a shunt reactor, the inductive blue LED on
the left side of the device lights up.
NOTE: During setup and stage recognition operations, if the Exit Key is held
down for 4 seconds, the current operation is canceled and terminated.
If an incorrect situation is encountered during installation; The device automatically
corrects some errors (e.g. voltage-current mismatch). In cases of incorrect connections that the
device cannot correct, the device stops the installation without completing the installation by
reporting the incorrect status as shown in Figure 8.

Enters menus and submenus, and also performs confirmation operations.
In the menu, it allows you to go back one step and exit the menu. On the
work screen, it allows you to return to the main worksheet.
Allows navigation in the work screen detail pages and menus. It performs
the process of increasing the values of the parameters.
Allows to navigate the work screen detail pages and menus. Performs the
process of reducing the values of the parameters.
General Features
Reactive Control Relays: 3 phase current, phase-neutral and phase-phase voltages,
frequency, active and reactive powers, angle difference between current and voltage
can be measured and displayed on the screen. In addition, it measures and records
active and reactive energies.
Demand and peak values for these measured quantities are also recorded by the
Reactive Control Relay and can be displayed on the device.
Many necessary adjustments related to the device (Current Transformer Value,
Measurement and Busbar Voltages etc.) can be made via the menu.
Thanks to the communication feature, all read parameters can be monitored
remotely via the standard MODBUS protocol and various adjustments can be made.
It can give output in the value range for the quantities (Current, Voltage, Active and
Reactive Power, Cos(φ) etc.) set via the device menu.
