IntroductionSinglephaseelectricmeter DDSY150-SSK is a new type of electric meter having the prepayment function. The usercan purchasesenergy from the vending network by getting the serial number ( named as " TOKEN"), which could be entered via keypad to load the pre-purchased energy. The TOKEN contains 20 digits which are encrypted. Because the activity of recharging is realized by keypad, this meter is named as " Keypad Meter". This meter is equipped with infrared communication port, double metering sensors, double control switches, real time clock unit, and other auxiliaries.The data transmissions protocol of DDSYXXXXcomplies with IEC62055-41 and IEC62056-21. All the specifications and performance index comply with IEC62053-21 regulations to Class 1.0 Static Meters for Active Energy. 2. Functions and features:2.1Active energy measurement; 2.2Adopt 20-digit token as data transmission media, you can purchase energy before consumption;2.3Double loop measurement both on neutral and phase lines,2.4 Accumulate the total energy with unit of 0.01 kWh;2.5 Display the real-time current and voltage;2.6 LCD display with backlight2.7 Low energy alarm to remind you to purchase energy;2.8 Double relays to control the neutral and phase circuits;2.9Infrared communication for data transmission and parameter settings2.10 Event record function (including cover opening event, tamper event and power failure event, etc.)2.11Ground line connection design;2.12Anti-tampering features( including opening terminal cover, short circuited, current injection, reverse wiring, magnetic disturbance, etc.)3.

Introduction of Meter Design4.1 LED indicatorLED from left to right in sequence are indicating -Pulse (RED color); -Power supply and credit status(bi-color, normal status in GREEN, low credit status in RED and blinks);--Alarm / Tampering (YELLOW color); 4.2 KeypadContains the keys of number from 0-9 and symbol "←" and "",used for input, cancel, /confirm/i, and check the TOKEN. 4.3Communication portOptical communication port complies with IEC 62056-21 /IEC 61107 protocol.4.4 Terminal cover detector used for detecting the terminal cover open status.5. Operation principleAs shown in Figure 5, the incoming current and voltage are input into the special energy measurement IC via separate sampling circuit, measuring chip exports the impulse signal by a ratio of measured power to microprocessor ( MCU ), MCU calculates and processes the impulse and perform the energy metering and load control functions etc. Because of bi-loop measurement, the energy is sampling from both phase line and neutral line, the MCU could read the real-time current, voltage, detect the real-time energy consumption status, and process the tampering condition. LED indicate the impulse, power/creditstatus, alarm, to show the meter working status. Meter has high-precision clock and super capacitor ensure the meter could work at least for 48 hours when power off. 6. Meter application6.1 Purchase energyPrepayment power vending management system will produce a 20 digits code (generated based on user's information and purchasing amount). You need to input this code to the meter with keypad. The meter will decrypt the code and write the purchased energy into the meter and will also add the energy into the balance energy and then save it. When the overdraft and abnormal power consumption occurred, the meter will deduct this consumption first and then the meter will save the balance energy into the meter. When you use the energy, the meter will deduct the balance energy according to relevant condition. The meter can power off the energy automatically when meter meets the condition of disconnection. The meter can recover to supply energy automatically when the meter meets the condition of recovery energy.When the balance energy is low, you can go to the vending station of the utility to purchase electricity. The operator will give the user a 20 digits token according to user's information and quantity the user purchased.Power purchase steps:go to local power supply bureauprovide your meter ID to the operatorinform operator the quantities you want to buyobtain a 20 digits token printed on your receipt.6.2 Input energyYou will input the code through meter's keypad to load the energy purchased. After encryption key verification, meter will accept energy and adjust the residual amount and accumulative power-purchasing amount and then save the final residual amount into EEPROM. At the same time power amount loaded this time will also be displayed on LCD.Input the token into meter steps:Input 20 digits token via keypad of the meterconfirm the code from LCDIf token is wrongly inputted, please use backspace to modify.Ifthetokeniscorrectlyinputted,press""to/confirm/ithetoken.iftokeniscorrect,LCDwilldisplay"BENAR"andtheenergyyoupurchased.Iftokenisincorrect,theLCDwilldisplay"GAGAL". 6.3 Token informationTOKEN code is composed by 20 digits, which should be entered via keypad. The meter sounds "Ding" when pressing the buttons of keypad. The sequence of number entering will starting from right hand side, and the last number entered will be shown on most right hand side of text display area. The LCD will show the digits entered, and also the number of digit. When you enters the 8th digit, the 1stdigit will be moved to the display area. Pleasesee more details as follows. DisplayDescriptionBefore pressing "←" button.When pressing "←" button, the last digit of "8" is deleted. After entering all 20 digits of TOKEN, press "" button to confirm and submit. If the TOKEN is correct and accepted, meter would display text of " BENAR" and buzz " Ding" for twice. If the TOKEN is incorrect and rejected, meter would display text of " GAGAL" or SErr information and buzz for 3 times.DisplayDescriptionAlready entered 9 digits, and the last digit is"9".Entered 20 digits TOEKN and press "" to check the TOKEN is correct or not. TOKEN is correct and accepted by meter, the credit is accumulated remain, means TOKEN is accepted. TOKEN is incorrect and rejected by meter, means TOKEN is rejected, GAGAL means TOKEN is incorrect. When TOKEN is incorrect and rejected, meter will display as follows.DisplayDescriptionBENARTOKEN is acceptedGAGAL(CRCError) The CRC value in the token is different to the CRC value as calculated from the data in the tokenTERPAKAI(UsedError) The TID value as recorded in the token is already recorded in the memory store of the payment meter USANG(KeyExpiredError) The TID value as recorded in the token islarger than the KEN stored in the payment meter memory7. Display functionThe meter has 3 display modes of automatic display, manual querying display and power down display. Meter starts automatic display of balance energy value and error information when power is on. When it is in automatic display mode, the screen starts with balance enegy and slipps for every 5seconds. The backlight will be ON and lasts for 15 seconds for pressing keypad, 10 seconds for pressing program button.7.1Automatic displayMeter will display the balanced energy and error information as follows in automatic display mode.

Alarm function8.1 Low balance alarmTo remind the customer to purchase balance in time, meter has two level low balance alarm and it can be set. Level 1: Green LED will flash and buzzing. This alarm can be canceled after pressing any button , but the alarm will come again without entering TOKEN.Level 2: Buzzing duration is shorter than level 1.Remark:All the "alarm duration" and "low balance threshold" can be set through entering the technical code of "123***" (*** is minutes) .8.2 Relay trip alarmWhen you install the meter, the duration exceeds limitation of 45 seconds, the relay will switch off, yellow LEDwill be on and buzzing. After 150 seconds, the meter will switch on again automatically.If the meter in overload condition accumulative exceeds 45 seconds in 30 minutes, the relay will switch off , but will switch on again after 150 seconds.The delay time can be adjust by computer.If the meter cover is opened, the relay would trip off with flashing "Alarm" LED, buzzing and indicator of tampering. The status of switch off could be canceled through enter the TOKEN "INPUNTED"If the power line is reversely connected, meter could measure as normal. But when balance energy is run out, meter will not accept any new TOKEN until it resume to "REPAIRED".
