• CARD READERThe interface that smart card is inserted to and provide communication between meter and smart card. Credit is easily loaded to the meter when the smart card is inserted to the card reader unit. After installing of credit, there is no need to leave smart card on the meter. Subscriber should remove the smart card from the meter.

• CUT OFF UNITMeter has a cut off unit for usage control. Cut off unit is a relay in electricity meter, valve in heat, gas and water meters. When credit finishes or unauthorized intervention take place, cut off unit is activated, consumption is stopped automatically.

• Occupancy rate of battery is reported to the subscriber by the LCD. Occupancy rate of the battery is also reported to the authority by the smart card. This way, ran out batteries are followed up and changed by the service.

• When battery runs out,consumption information is saved to the non volatile memory. Elektromed prepayment water and gas meters shutdown itself and stop consumption when the battery runs out. Elektromed prepayment electricity meter use network energy when the battery runs out.

• Meters have two security switches. These switches are under main body cover and battery cover. If any of these covers are opened by unauthorized personnel, meter record these intervention details (date, time, type etc.) in to the memory and active cutoff unit to close itself and stop energy and water consumption. In this case, meter only opens by the auhority service.

ELECTRONIC METER FEATURES

• Electronic meters in the system have automatic open/close units. Energy and water meters’ open/close feature is used by the subscriber’s smart card. Consumed energy and water amount is deducted from the loaded credit.

• There is no need to leave smart card on the meter, Subscriber should remove the smart card after loading credit.

• When the loaded credit in the meter drop below a predefined level, “CREDIT LOW” message is displayed on the LCD.

Subscriber is warned to buy credit by the messages. Subscriber should purchase new credit and load to the meter via smart card.

• If the subscriber does not take this messages into consideration, cutoff unit gets activated when the remaining credit is finished. In order to use energy and water, credit must be loaded again.

• There are two locations in meter memory for credit information: Main Credit and Backup Credit. Backup credit system is developed for subscribers to be able continue using energy and water in case of credit finishing out of office hours and weekends where they can not buy new credit. Backup credit is defined by the authorities according to the longest holiday time.

• When subscribers purchase credit, purschased credit is installed to subscriber’s smart card. This credit istransfered to the meter when the smart card is inserted to the meter. Transfered credit is first loaded to the backup credit location in the memory, then remaining credit is loaded as main credit.

• Meter starts to use backup credit after main credit ends. When the main credit ends, meter close valve/relay and stop consumption. In order to use the backup credit subscriber have insert the smart card to the meter. Meter will open itself for consumption. This way subscriber is warned and reminded to buy new credit.

• When the backup credit ends before the subscriber loads new credit, meter will close valve/relay and stop energy and water consumption.

• Subscriber may purchase and load new credit before the credit ends. New loaded credit will be added to the remaining credit in the meter.

• Every subscriber have their own smart card. One subscriber can not use other subscriber’s smart card. Subscriber’s meter does not accept other subscriber’s smart card.
