Figure-59
To change the current transformer ratio, press the set
button while the figure-58 is on the screen. Figure-69
comes to the screen. Press right button to move between
digits. Press the down key to change the value of the digit.
You can change the digit value which is the underline.
When you press the set button after entering the ratio,
the current transformer ratio is recorded and the screen
shows figure-59. You can scroll through the parameters
To change the voltage transformer ratio, press the set
button while the figure-60 is on the screen. Figure-70
comes to the screen. Press right button to move between
digits. Press the down key to change the value of the digit.
You can change the digit value which is the underline.
When you press the set button after entering the ratio,
the voltage transformer ratio is recorded and the screen
shows figure-60. You can scroll through the parameters
in the menu by pressing the right button or you can exit the menu by pressing the Esc key.
Example:
100 / 5A current transformer ratio (multiplier value) is 20. The CTR value needs to be set to 0020.

Example:
Medium voltage (M.V.) = Enter the ratio of the voltage transformer that converts 34.500V to 110V.
The ratio (multiplier) is calculated as 34,500 / 110 = 313,6 voltage transformer ratio. The VTR value must be
set to 313.6.

RS485 Remote Communication Settings
Figure-71
To change the RS-485 remote communication settings,
press the set button while figure-61 is on the screen.
Figure-71 comes to the screen. Two parameters can be
set here. Baudrate (br -communication speed) and
Modbus ID (Id - the number that identifies the device on
the RS 485 line). Press the right button to move the point
(.) to the parameter you want to set.
Then change the parameter value by pressing the down key. When you press the Set button, the changes
that you made are saved and Figure-61 comes to the screen. You can scroll through the parameters in the
menu by pressing the right button or you can exit the menu by pressing the Esc key.
Modbus ID (MBID) value; when more than one communication devices connect to a modem, Serial number
or ModBus address must be different. In such cases, enter a different value from other devices.
Baudrate(br):
1200 - 115200 bps,
ModBus ID(Id):
1 - 247
Stop bits:
1,
Party
: none.

Deleting Energy, Demand and Event Records:
To delete the records, press the set key while the
screen is shown. Figure-71 comes to the screen. You can
delete 3 records here. Energy (En), Demand (dE) and
Event logs (LE). Press the right key to move the point (.)
to the record which you want to delete. Then press the
down key to change the value to "yes". The record value
which you do not want to delete must remain in "no".
When you press the Set key, only records with the value "yes" will be deleted and the Figure-62 comes to
the screen. You can scroll through the parameters in the menu by pressing the right button or you can exit
the menu by pressing the Esc key.
