MAIN FUNCTIONS 2.1. Gauging: The electricity meter gauge the total active and reactive power and demand Programming the Electricity Meter: Time slices and tariffs are programmable. For a whole day, 8 different time slices may be determined and each time slice may be selected and paired with one tariff out of four. Furthermore, the electricity meter has a feature capable to tariff individually the weekdays, Saturdays and Sundays. On the electricity meter, the date and time, tariff data and demand receiving period may be adjusted by the authorized TEDAŞ personnel by opening the lid of electric terminal box Reading the Electricity Meter: Invoicing data for 24 months, consumed total power amount, data about lid openings of electric terminal box, demand data for 12 months and initial opening date of upper lid can be read on optic port or RS485 outlet of the electricity meter Auto Trouble-Shooting Feature: The electricity meter continuously controls its internal circuits and displays in the menu of its monitor the trouble types shown hereunder. For trouble displays and details, please refer LCD MONITOR INDICATORS Electric Terminal Box Lid and Upper Lid Opening, Closing, Recording Features: When the upper lid is opened, the first opening date is stored. When the lid of electric terminal box is opened, the first opening date of each month and total of openings throughout the relevant month is stored. Lid opening dates and numbers of the most recent 24 months are stored in the memory Signal Output: On the electricity meter, there is two LEDs so as to indicate the consumed active and reactive energy. Numbers of blinks of these LEDs shows lmp/kwh and Imp/kVarh values of the electricity meter lmp/kwh : 1000 Blink = 1kWh, 1000 lmp/kvarh: 1000 Blink = 1kVarh lmp/kwh: Blinks = 1kWh, lmp/kvarh : Blinks = 1kVarh 2.7. Summer / Winter Day Light Saving Time: The electricity meter automatically switches to summer / winter day time light saving time. This feature might be cancelled by request Displaying during Power Failure: When the power is cut, the data requested can be brought to the LCD monitor via the call-button on the electricity meter and reading can be taken from optic port. This operation is limited with 5 minutes for the sake of battery life. When the power is cut, taking reading from RS485 outlet is not possible. (3)

Communication: The data is transmitted to a portable computer (indexor) through an optical reader from optic port of the electricity meter. Moreover, through the RS485 communication outlet that is standard on all combined electricity meters, remote access to the electricity meter data is achieved. When the power is cut, taking reading from RS485 outlet is not possible. 3. STRUCTURE AND OPERATION PRINCIPLE OF THE ELECTRICITY METER 3.1. Structure of the Electricity Meter: Casing and lids of the electricity meter are compliance with IP54 Outdoor Standard and fully sealed. The electricity meter is made of high-grade non-flammable engineering plastics. All electronic components are laid on a special PCB card; and these cards are mounted to the casing of the electricity meter. Following calibration of the electricity meter, the upper lid is screwed in the factory and sealed. The lid of electric terminal box is sealed by authorized TEDAŞ personnel following assembly of the electricity meter Block Diagram of Operation Line Input R ST N Power Stage Voltage Sampling Current Sampling Line Output R S T N Gauge Chip Test Output Micro-processor Button 4. STARTING-UP THE ELECTRICITY METER Normally the electricity meter as well as the LCD monitor operates, when the meter is mounted and powered on Controlling the Functions Once the electricity meter is mounted, its electrical connections should be checked whether they are proper or not. After the electricity meter mounted properly to its place, the screw on the lid of the electric terminal box should be tightened. 2 nd lock indicator blinking on the LCD monitor will disappear after the first reading. If not, then it means either the lid of the electric terminal box is not attached properly or its screw is not tightened well Operation of the LCD Monitor Following initial operation of the electricity meter, the automatic menu mod will activate within 90 minutes. Each menu of the relevant mod will be displayed for 5 seconds and then automatically proceed to the next informative menu. When the call button on the electricity meter is pushed down, the button menu mod will activate. If no button would be pushed down for the following 90 seconds, the electricity meter will return to the automatic menu mod. When the call button of the electricity meter is pushed down for 3 minutes, the sub menus will be activated. This menu generally contains the data pertaining to the previous months. To return to the button menu, the call button should be re-pushed for 3 minutes. (4)

7 5. LCD MONITOR INDICATORS Definitions of the symbols and indicators on the LCD Monitor are as follows: 1 2 The Upper Lid is Open (The Lock numbered 1): This symbol indicates that the upper lid is opened. If the indicator is blinking while the lid is close, then it is indicating that the lid is opened earlier. If the indicator is being displayed on the monitor solidly, then the upper lid is on open position. The Lid of Electric Terminal Box is Open (The Lock numbered 2): This symbol indicates that the lid of the electric terminal box is opened. If the indicator is blinking while the lid is close, then it is indicating that the lid is opened earlier. If the indicator is being displayed on the monitor solidly, then the lid is on open position. Symbol will disappear after the electricity meter is read. Clock Error: If the clock does not operate normal, this symbol will be displayed. Battery of the System: If the voltage of the battery of the system is low, this symbol will be displayed. Battery of the Clock: If the voltage of the battery of the clock is low, this symbol will be displayed. L1, L2 and L3 symbols indicate existence of, respectively, R, S and T phases. For instance, if the R phase has no voltage, only L2 and L3 symbols will be displayed on the monitor. If L1, L2 and L3 symbols are blinking together, it means there is an error on phase sequences. If the energy current of one or more phases are in reverse direction, there will be - mark in front of the relevant symbol. For instance, if the energy current of L1 phase is in reverse direction, -L1, L2 and L3 symbols will be displayed on the monitor. This symbol indicates an error on inner memory units of the electricity meter. These symbols indicate currently active tariff. For instance, if the present date/time is corresponding to T2 tariff, T2 will be displayed on the monitor. In the event of any failure on the clock of the electricity meter, T1 will be active continuously. This is the reactive penalty pre-warning symbol. If the current Inductive or Capacitive energy consumption is over the limits determined by TEDAŞ as to the active energy consumption, this symbol will blink. If the consumption will go on that way and the energy consumed at the end of month is exceeding determined limits, the symbol will light up continuously. In such case, the user should have the existing compensation system controlled, or at least set. The point symbol on the right lower corner of the LCD monitor flashes in periods of half second. This indicates that the electricity meter operates steadily. During the data of the electricity meter is read through optic port or RS485, the point symbol will flash rapidly to indicate that the data is being transferred. When the reading is over, the point symbol will return to its normal position. (5)

8 This symbol indicates characteristics of the energy current in the system. For instance, if the current from R phase is in the direction to +P and +Q, and from S phase in the direction to +P, and from T phase in the direction to +P and -Q, then arrows will be displayed in the monitor as seen on the right hand side. 5.1 Samples from Display List 1.
