    ELECTRONIC ELECTRIC COUNTERS

    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.

    KHLER A..

    ATTENTION:

    PLEASE READ THE MANUAL CAREFULLY BEFORE THE ASSEMBLY

    OF THE COUNTER.

    Assembly of the counter should be made only by the licensed expert

    personnel.

    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.

  • 1- INTRODUCTION

    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

    alert

    Counter battery is weak

    alert

    Time error

    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

    3.1- Structure

    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

    mounted.

  • 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

    fastened.

    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
