INSTRUCTIONS OF USE
INFORMATION ON THE DESIGN OF
MONOPHASE ACTIVE PREPAID
ELECTRONIC ELECTRIC COUNTERS
The electric-electronic counters of which the instructions of use are given in this
manual have been produced with the advanced technology in accordance with the
specifications published to organize the multi-tariff electricity sales and to encourage
the electricity savings by Electricity Distribution Joint Stock Company of Turkey
(TEDA) and the Turkish Standards TS EN 62052-11 and TS EN 62053-21. The
counters measure the active electricity energy and the maximum power used, display
the data on LCD screen, set the daylight saving application automatically, keep the
required information and programs on memory and allow accessing the said
information when required.
PLEASE READ THE MANUAL CAREFULLY BEFORE THE ASSEMBLY
OF THE COUNTER.
Assembly of the counter should be made only by the licensed expert
Parts with high voltage should never be touched during the assembly.
Power should be cut off during the assembly and disassembly.
KHLER electronic counters are products of highest technology. All technical
instructions and documents are the intellectual property of the company. They
cannot be reproduced or used by third parties.
This manual offers specific and summarized information about the counter.
The conformity of the counter used to the network and the installation should
be checked by the expert personnel. Otherwise, selection of incorrect counter
or connections may cause damage to the counter. In such cases, damaged
counters are not covered by warranty.
Data displayed on the screen are predetermined by TEDA.
All Monophase Active counters measure the active energy with high quality ADC
with high precision and process it with digital signal processor. All electronic
counters are equipped with advanced features such as date and hour, measuring
under 4 tariffs, data transfer, signal output, recording data for 12 months etc.

2.6 Main Functions
Measurement: Counter measures total active energy under 4 different tariffs.
Programming: Time zones and tariffs can be programmed. 8 different time zones can be set within a day and each time zone may be matched to any 4
tariffs. Different tariffs can be selected for weekdays, Saturdays and Sundays.
The date and time and tariff information on the counter can be changed by
authorized TEDA personnel by opening the electric terminal cover.
Reading: Billing information, total consumed energy, electric terminal cover opening information for 12 months, demand information for 6 months and the
date when the upper lid is opened can be read on the counter by an optic port.
Automatic Trouble Shooting: Counter automatically checks the internal circuits and displays the following error types on its screen.
Upper lid open alert
Electric terminal cover is open
Counter battery is weak
Electric Terminal Cover and Upper Lid Opening and Closing Recording:
In case the upper lid is opened, the date when the lid is opened for the first
time is recorded.
In case the electric terminal cover is opened, the first date when the cover is
opened for each month and the total number of opening within that particular
month are recorded.
Date when the cover is opened and opening number are kept in the memory
for the last 12 months.
Communication: Data obtained through optic reader placed on the optic port in the counter are transferred to a portable computer (indexer).
Signal Output: A LED is placed on the counter to display the consumed active energy. The number of blinking of this LED shows the Imp/kWh value
of the counter. 1600 Imp/k Wh: blinking 1600 times = 1kWh
Daylight Saving Time Setting: Counter makes the daylight saving setting automatically.
Running Display when the Power is cut off: When the power is cut off, the required data can be recalled to LCD screen through a button on the counter
and this data can be read by the optic port.
3 STRUCTURE AND OPERATING PRINCIPLE OF THE COUNTER
The body and the covers of the counter are in conformity with IP54 Outdoor standard
and are leak-proof. They are made of high quality fireproof plastic.
All electronic components are aligned on a special PCB card and these cards are
mounted on the counter body. Upper lid is screwed after the counter is calibrated at
the factory and sealed by the Ministry of Industry and Trade of Turkey.
Electric terminal lid is sealed by TEDA authorized personnel after the counter is

4 STARTING THE COUNTER
To start the counter, one should first add units. When the counter is mounted and
power is supplied, it operates regularly and LCD screen start to display. If no unit is
added to the counter, the screen works, but due to the relay inside the counter no
energy reaches the line.
4.1 Control of Functions
The electric connection of the assembled counter should be controlled. After the
counter is correctly mounted, the screw of the electric terminal cover is fastened. 2nd
lock sign blinking on the LCD screen will disappear after the first reading. If not,
whether the electric terminal cover is not connected correctly or its screw is not
4.2- Operating the LCD Screen
As soon as the counter starts to run, the auto-display mode becomes active. Each
menu of the screen is displayed for 5 seconds and automatically the next information
menu is shown.
When the button on the counter is pressed, screen-recalling mode becomes active and
the information on the screen is displayed for 1 minute. After 1 minute, the screen
again passes to auto-display mode.
5- LCD SCREEN MENU
The definitions of the symbols and information on the LCD screen are given below.
Upper lid is open This symbol appears when the upper lid is open. If the symbol is
blinking although the lid is closed, it means that the lid has been
opened in a previous intervention. If the symbol is constantly
displayed on the screen, it means that the upper lid is open.
Electric terminal cover is open This symbol appears when the electric terminal cover is open. If the
symbol is blinking although the cover is closed, it means that the
cover has been opened in a previous intervention. If the symbol is
constantly displayed on the screen, it means that the electric
terminal cover is open.
Time Error: If time is not running regularly, this symbol is displayed.
Counter battery: This symbol appears if the battery is weak.
Tariff indicator: It shows the tariff zone where the
counter is used.
It symbolizes the tariff info rea
