Meter terminals are made of brass with nickel plated, which is suitable even for tropical climate. Meter is equipped with sealable terminal cover. Keypad prepayment Meter has two deduction modes: energy deduction mode and money (amount) deduction mode.

Energy deduction mode:

Meter calculates consumption based on energy consumed (i.e. kWh). The credit recharged in the meter is also energy (i.e. kWh).

Money (amount) deduction Mode:

Meter should be configured with tariff (flat tariff, TOU tariff or step tariff)first. Credit in the meter is displayed as money amount. Balance amount will be deducted when every 0.01kWh is consumed (i.e. 0.01kWh X tariff rate is the amount to be deducted every time) .

Money (amount) deduction----TOU tariff application instruction: 4 tariff rates and 12 time shifts can be programmed each day. According to electricity using



situation in one area, utility can adjust electricity price at different time shifts to encourage electricity use at off-peak period and save at peak period.

Tariff Setting Meter’s tariff can be programmed through AMI/AMR system and local communication port (optical communication port, RS-485 communication port). Tariff programming is strictly secured with security module and key. Tariff setting comes with tariff version index and tariff activation date/time. Meter is stored with two sets of tariff: when one tariff is in use, the other set of tariff can be programmed and activated at certain date/time to replace the in-use one. After replacement the old tariff will be deleted automatically and get ready to accept new tariff.

Note：Other parameters’ errors except for energy(active /reactive /apparent) will be calculated through following formula:

Metering error (%) = (measured value-actual value)/ measured fundamental value *100%

Definition of measured fundamental value: Voltage is rated voltage of energy meter; voltage measurement range is 0.6Um--1.2Um。

Current is maximum current of energy meter; current measurement range is 0.05Ib--Imax

4.8 Energy meter harmonic measurement THD DTZ1513 three phase CT/PT connected energy meter’s voltage/current’s sampling speed is 3.2



kHz (Broadband response characteristics). The sampling data includes 41 times’ harmonic information.

■ Active energy’s harmonic measurement:

P= U1I1 cosφ1 + ∫（UnIncosφn ）

n = 2、3、4、…… 41

■ Reactive energy’s harmonic measurement

Q= U1Ia1sinφ1 + ∫（UnInφn sinφn）

n = 2、3、4、…… 41

Result: Active/reactive power include 41 times’ harmonic information. The THD of full wave

energy by active/reactive energy measurement is small.

4.9 fundamental wave measurement (optional) DTZ1513 three phase CT/PT connected energy meter can independently measure (50HZ) fundamental wave active energy and eliminate harmonic wave’s negative effects. It makes measurement fairer and ensures electricity company profit as well. DTZ1513 three phase CT/PT connected energy meter adopts digital signal processor to do digital filtering of ADC sampling data and eliminate harmonic wave. After that, it comes to fundamental wave measurement. The filter’s attenuation to harmonic wave is three time’s harmonic wave-30dB, five time’s harmonic wave-60dB, seven time’s harmonic wave-90dB. The calculation of harmonic wave’s distortion rate is made after getting the fundamental wave data as well as full wave data.



THD（Total harmonic distortion）: Ratio of Root-mean-square values between harmonic content in AC power frequency grid and fundamental wave content

THDu:

U1: fundamental voltage

UH:Harmonic voltage content

THDi:

IH: Harmonic voltage content

5 Meter TOU measurement function DTZ1513 three phase CT/PT connected energy meter can measure active/reactive energy with TOU function. Meter supports 8 tariffs and 24 time shifts. Tariff shift is based on a daily tariff table as the basic unit. The meter can prestore up to 16 sets of daily tariff table, and then based on the festival tariff table, seasonal tariff table, and weekly tariff table to select the corresponding tariff table so as to realize tariff swift in different holidays, seasons, and working days in the same week. Tariff consists of the following basic units:

Sr/N Basic unit Number

of bytes

Note



1 8 tariffs

2 Up to 24 time shifts per

4 16 daily tariff

5 12 weekly tariff

6 12 seasonal tariff

7 50 holiday tariff

8 8 tariff rate tables

Note: For direct connected single /three phase keypad prepayment energy meter, it only has active electricity rate.

5.1 Daily tariff Daily tariff defines in every daily time shift to use with tariff rate code. When a new day comes (at 00:00:00), meter will select a daily tariff according to program of holiday tariff, seasonal tariff and weekly tariff. Meter can store maximum 16 different daily tariffs.

Daily tariff includes the following information:

Daily tariff table code.

It is applied to the status data (1 valid, 0 invalid) for 8 tariff time shifts, and maximum 24 starting time (hh: mm). The information input will be valid from midnight to the specified time at midnight. From 00:00 to 24:00, each time shift will start from the ending time of the last shift. When it is 0 second of every minute, in accordance with the status data of present time shift and tariff time shift in executed daily tariff table, the energy meter can define the tariff which is for current time shift measurement, and calculate forward /reverse active energy measurement from starting time to ending time within this time shift, and save them in the corresponding register so as to realize the function of TOU measurement.

Each daily tariff is 73 bytes. The first byte of daily tariff code: 7XH X is daily tariff table code Range: 1-F Daily tariff values are starting from the second byte. The basic unit of Daily tariff table is of every 3 bytes. The unit of Daily tariff is hh:mm; Tariff code.(72 bytes unit in total) 12 Daily tariff in total is 16X73=1168 bytes. The minimum time shift is 15 minutes, and should be larger than the setting of demand calculation period.



5.2 Weekly tariff According to working day and weekend day, daily tariff codes for a week can be defined. Weekly tariff defines effective day tariff table types on variety of occasions from Monday to Sunday. The administrative department can store maximum 12 different weekly tariff tables. It can set different daily tariff tables for every day of a week to differentiate each other (such as difference between working day and weekend). It can also set the same daily tariff code to use the same type of tariff.

There are 8 bytes for each weekly tariff. The first byte is the number of weekly tariff , while for the last 7 bytes, each byte is in accordance with the number of daily tariff from Monday to Sunday. 8X12=92 bytes in total.

5.3 Seasonal tariff Based on the cost of electricity generation and the anticipation on the electricity market, different weekly tariff adopted in each season can be defined. Seasonal tariff defines the choices of weekly tariff table in practical use. Energy administration department could define up to 12 seasonal tariffs in different periods and situations. So the administration can work on the seasonal differences of tariff shift. The seasonal tariff table is annually repeatable as the year factor is not taken into consideration. The simplest situation is that there is only one weekly tariff number and the unique tariff number is used from January 1st, (Seasonal tariff is like year time zone. State Grid demands 2 time zones in a year.)



Seasonal tariff table

Starting from Jan.1st, the starting date (Month and Date) of each season is the ending date (Month and Date) of the last season. Sequence in ascending order is MM/DD. 4X12=48 bytes in total.

5.4 Holiday Tariff In public holidays and festivals, the administration can select the particular daily tariff table in special days. So the particular tariff forms holiday tariff. Holiday tariff defines different daily tariff in public holidays and festivals. Meter can store up to 100 special days. For regular holidays (same day for every year, for example Jan 1st ), a special code “A1H” can be set. In the host computer or HHU, MMDD can be set to show this day is valid for every year. For the unfixed holidays (different day in different year, for example Easter Day or Chinese Spring Festival), data should be input each year in the term of YYMMDD. Maximum 50 Festivals can be set in this type of meter as well as there are 50 tables in this meter. Estimated validity period should be arranged and the time shifts of the festival tariff table should be modified in practical use.



The basic unit is 5 bytes, the first byte is the number of holiday tariff, the second, third and fourth bytes are respectively YY/MM/DD of the holidays. The fifth byte is the number of daily tariff, all 5X50=250 bytes in total.

Every tariff is in correspondence with four tariff rates: forward active / reverse active / forward

reactive/ reverse reactive. There are 8 tariffs, and every tariff is in correspondence with four tariff

rates. Tariff rate consists of tariff code, forward active rate(four bytes) / reverse active rate(four

bytes) / forward reactive rate(four bytes) / reverse reactive rate(four bytes) . 8X（1+4X4）=136

bytes in total.

5.6 Confirmation of valid daily tariff At 00:00:00 each day, the energy meter will select proper daily tariff number from Holiday Tariff table, Seasonal Tariff table and Weekly Tariff table, then the daily tariff table of that day can be selected to RAM from ERROM. (For the energy meter which RAM is relatively small, time Daily tariff table of the present and the next period can be put in). At 0 second each minute, the energy meter will process the period of daily tariff, according to the present daily tariff table, to conduct tariff measurement control. It can be referred as follow:



5.7 Spare tariff As the changes of resource and the energy supply, as well as electricity generation, transportation and the electricity cost, tariff should be changed accordingly. Due to big quantity of energy meters and the dispersion of locations, it’s impossible to modify the tariff for all meters at the same time. In order to solve this problem, a set of spare tariff which is pre-stored in the meter is applied. Utility can set activation date for the spare tariff. When the spare tairff is activated, meter will start to use new seasonal, weekly, daily and holiday tariff. After activation, the previous tariff will be no



longer valid. In such way, utility can upload spare tariff to meters and on activation date all meters will excute new tariff.

Spare tariff and its activation date will be saved temporarily in the meter, after activation, the old

tariff information will be deleted and meter will be able to accept another set of spare tariff.

5.8 Step Tariff Measurement Function (Optional) DTZ1513 Three phase CT/PT connected energy meter can define different step tariff rate according to monthly consumption. The step tariff rate consists of units as follow:

There is one set of spare Step Tariff table. It will activate on the appointed date; The activation date and the new step tariff will be stored in the meter temporarily, after activation, the old tariff information will be deleted and meter will be able to accept another set of spare tariff. The new Step Tariff Table’s temporary memory is 136 bytes + the year and month of usage. The step tariff is 272 bytes in total.

5.9 Tariff Data Settings The tariff (holiday tariff, seasonal tariff, weekly tariff, daily tariff and spare tariff) can be programmed by the tariff setting software organized by the R&D Center of INHEMETER. After setting and confirmation, communication data module will be generated in accordance with energy meter’s communication protocol, and data can be loaded to the meter through follows: A. Infrared (HHU or PC) local setting B. RS-485 communication port (HHU or PC) local settings C. Remote batch setting

When it is not factory settings (such as on site modification or user preference): A: To modify tariff and electricity rate by local communication, operator needs to turn on the programming switch (with seal protection), which needs password authentication. B: To modify tariff and electricity rate by remote communication, operator must go through authorization and password authentication via data management center, it can also go through all or selected meter type/meter No. to modify the tariff and electricity rate in batch mode. Meanwhile meter must be allowed in remote programming mode.

CIU installation instruction:

1. Separate the cover and base of CIU before installation 2. Insert the two-wire communication cable through cable hole on CIU base, fix the cable

on CIU base with related cable buckles, then fix CIU base on the right position with 2 screws.

3. Stick the bar code (ID) at bar code place. 4. Connect the communication wire. 5. Lock up CIU cover to CIU base.



6. Power on and check if meter and CIU work properly. If communication fails, re-check from step 1.

CIU opening method diagram To open CIU cover, push the middle position on right side to loose the cover lock. It is suggested that CIU should be installed on the wall; or on the table or platform where it is easy to operate. After fixing CIU, before connecting communication wire, user should check if MCU is installed correctly, if MCU works properly, if the CIU serial number is matching with MCU. When all is checked and correct, communication wire can be connected and CIU can be enabled.

7.6 CIU (wire communication) display instruction When CIU is powered on it starts self-checking procedure to check communication with MCU, the LCD on CIU will first display communication mode (please refer to picture 1).



If the communication is normal, LCD on CIU will display balance energy/credit (please refer to picture 2), integrated relay indication is on connected position.

If communication is abnormal the LCD will not work, following are the solutions:

A：Check again if the communication wire is connected properly on CIU and MCU. B：Check if

MCU is powered on and working well. C：Repair and maintenance.

MCU data can be checked on CIU by following methods:

A：Manual scroll display mode: push the enter (blue) button on keypad, and manually ckeck data

items one by one.

B：Short code mode: input short code and push enter (blue) button, appointed item can be

displayed. Notice: the display time of each item is 10 seconds (during whitch CIU locks up communication and no response to inquiry in this period), only when display returns to default item (balance credit), next short code can be input.

7.7 Special display Symbol

Display method (example) Item description

CIU is communicating with MCU, please wait.

Display：no_USEd It means the item you are checking is not used.

There are several TOKEN codes with special functions for keypad prepayment energy meter- technical Token, which can be applied for power off recovery due to tampering, record clearance, meter load threshold setting, etc. These special TOKEN codes are generated dispersedly according to each energy meter by vending Management System.

7.8.3.1 Tampering clearance TOKEN

If the power is cut off by opening of terminal cover, the user must go to vending Management Center to apply for

tamper clearance TOKEN code to have power supply recovery. After inputting temper clearance TOKEN code, the meter will be recovery from tamper power failure to supply power.

7.8.3.2 Load threshold TOKEN

Load threshold can be changed by inputting load threshold TOKEN. If preset load threshold is low as user load demand increases, which brings about frequent overload consumption or overload power off, the user needs to go to Power Supply Management Department or Vending Department to apply for additional requirement of power load, and a new load threshold TOKEN code will be provided after the application is permitted by Vending Department. Meter load threshold setting will be revised by inputting new load threshold TOKEN code.

7.8.3.3 Credit clearance TOKEN

If energy meter needs to be changed or maintained or user is changed, after confirming related data, the user can input a KWh clearance TOKEN to reset remaining energy/credit. Built-in relay will be disconnected to cut off power supply.

7.8.4 Special TOKEN

The following special TOKEN codes are special extended functions for keypad prepayment energy meter made by INHEMETER.



7.8.4.1 Pre-warning threshold TOKEN

Remaining KWh pre-warning threshold value and function can be set by inputting code: 4547

8xxx, the value which can be set as 0kWh~999kWh.

7.8.4.2 Warning threshold TOKEN for low remaining credit

Remaining KWh warning threshold value and function can be set by inputting code: 4547 9xxx,

the value which can be set as 0kWh~999kWh.

Details refer to 6.8 pre-warning, warning function for low remaining credit

7.8.4.3 Processing activation TOKEN after Installation

Meter relay is on disconnection status since delivery from factory. After completion of installation, 20-digit special TOKEN code should be input on the keypad to activate meter working( relay is connected ). Meter relay is always on disconnection status before activation no mater preset at factory, user recharging, or if there is remaining credit. Processing activation TOKEN can be used only for one time as per one meter. Once meter is activated, it will not be restricted. Activation TOKEN will be issued by INHEMETER.

Activation TOKEN： 1285-4194-1448-6450-5980

7.8.5 Test TOKEN (Non-specified meter TOKEN) There are some non-specified TOKEN codes for prepayment keypad meter which are used for

meter function test. Once the meter accept these TOKEN, the meter will practice corresponding

tests.

it will last 5 seconds. After test, meter returns to normal working mode.

7.8.6 Extended function TOKEN The setting data of overdraw threshold and Minimum guarantee power consumption can be

transformed to TOKEN via vending system.

8 Special functions 8.1 Load cut off function There is built-in relay for DTZ1513 CT/PT connected prepayment keypad meter. According to user’s credit (balance amount), tamper status, load control status and power supply, it can output control signal and control outside HV/LV breaker, and realize load power control. Relay status indication on LCD

“ ” It means built-in relay is connected, and power load is available.

“ ” It means built-in relay is disconnected, and power load is not available.

Notice: If the relay status indication on LCD does not match the real status, it maybe malfunction,

and user should inform electricity management department to check.

8.2 Zero credit power off When remaining credit in the meter is zero (except overdraw, friendly data/time), the built-in relay will output control signal immediately and control outside HV/LV breaker to disconnect, and realize power off. After user recharging, meter will output automatic power supply recovery information and control outside HV/LV breaker to connect, realize power recovery.



8.3 Load control function DTZ1513 CT/PT connected prepayment keypad meter has load control function. The load control function of DTZ1513 CT connected prepayment keypad meter complies with the load control algorithm method specially mentioned in SCSSCAAA9 item 7.7.2 of Eskom.

Notice: Meter load control function cannot be used to protect load security protection. It is

normally used to control the users average load upper thresholdin a associated area. (mainly

concerned with grid security, cable loss reduction and power supply cable load limit). Load

connected to CT/PT means primary winding load (Transformation ration algorithm)

Automatic delay recovery mode after over load power off. A. If one phase load is beyond load threshold value 132.000kWh (OBIS code 21.35.0 data

item), the alarm will sound and LED indicator will flash, and LCD on MCU/CIU will display overload information, and switch to display on real time present overload phase power.

Above 2 LCD display by shift, which means it is in overload status and current load is 140.80kW. B. If the consumption load is beyond load threshold for more than 45 seconds, the built-in relay will cut off power at 45th second. After 150 seconds, the relay will connect automatically (power supply will not work during the 150 seconds). And LCD on MCU/CIU will display remaining time for power recovery (unit: second; it means remaining lock time. The remaining lock time will reduce by a second interval).

If the user does not low down the consumption load, which is beyond threshold value, above process will repeat (Power off- Delay recovery- Power off).

C. Within 30 minutes, if tripping occur for 5 times, meter will cut off power supply and last for 30



minutes. And power supply will automatically recover after 30 minutes. LCD will display remaining lock time, it will reduce by one second interval. And LCD will display power at the last power off. The recovery time after 5 tripping within 30 minutes can be programmable. Min. time period is 5minutes. It is default 30minutes at factory for this project.

Load control threshold for this project

Three phase four wire CT connected meter (LV): 1.320kWh X CT Transformation ratio.

Three phase three wire CT/PT connected meter (HV): 1.320kWh X PT Transformation ratio

X CT Transformation ratio.

Notice: When overload tripping occurs constantly, the user should check the power consumption

load , and contact electricity company to modify load threshold.

D. If times of overload power-off are more than allowed threshold value which preset (check

OBIS F.L.3), the meter cannot recover power supply automatically after overload power-off. The

user should inform electricity company and apply for load threshold change TOKEN or tamper

record clearance TOKEN, and meter can recover power supply after TOKEN inputting.

Optional function: ① Overload is judged based on active power or apparent power which is

decided by meter prepayment status word. The default is active power at factory.

② Options for power supply recovery after overload power off: automatic

delay recovery or key-press immediate recovery.

③ Please check prepayment configuration instruction for more information.

8.4 Protection against Voltage Abnormity of Grid Keypad prepayment meter is designed for protection against voltage abnormity of grid so as to reduce possibility of electronic appliance damage when voltage abnormity of grid occurs.

8.4.1 Automatic Power Off Energy meter will automatically power off (cut off subscriber circuit), and indicate power-off status and display corresponding phase voltage value when grid phase voltage is lower than < threshold value of voltage under condition of low voltage power-off, OBIS code 12.31.0 >, and keeps the



situation for 30 seconds; or grid phase voltage is higher than < threshold value of voltage under condition of overvoltage power-off, OBIS code 12.35.0 >, and keeps the situation for 3 seconds.

Lo_UoL: 108.00V :

It means power-off at low voltage It means voltage value before power-off

OUEr_UoL: 306.70V :

It means power-off at hight voltage It means voltage value before power-off

Note: It’s programmable to set threshold value of grid phase voltage abnormity, and it’s available

to check threshold value by OBIS code.

OBIS code12.35.0： threshold value of voltage under condition of overvoltage power-off

OBIS code12.31.0： threshold value of voltage under condition of low voltage power-off

8.4.2 Recovery of power supply A: Automatic recovery of power supply

Energy meter will automatically recover power supply when grid phase voltage recovers between <threshold value under condition of low voltage power-off OBIS code12.31.0 > and <threshold value under condition of overvoltage power-off OBIS code 12.35.0 >, and last 5 minutes.

B：Manul recovery of power supply

Energy meter can manually recover power supply by keypad before automatic recovery when grid phase voltage recovers between < threshold value under condition of low voltage power off



OBIS code 12.31.0 > and < threshold value under condition of overvoltage power off OBIS code 12.35.0 >. Note: There will exist not more than ±3V error value in meter for above voltage range determination due to such serious voltage deviation.

Energy meter will cancel protection against low voltage power-off if threshold value under condition of low voltage power-off set as zero; Energy meter will cancel protection against high voltage power-off if threshold value under condition of high voltage power-off set higher.

8.5 Anti-tamper against Cover Opening Counter & Power-

off Energy meter has activated anti-tamper against cover opening counter(terminal cover or upper

meter cover) & power- off after delivery from factory.

8.5.1 Energy meter will instantly power off once the

terminal cover or upper cover is opened under condition of

power- on. Energy meter shall recover power supply after upper cover and terminal cover are taken to original position, and input corresponding TOKEN while meter still remains balance amount and other problem is free.

8.5.2 tripping at terminal cover opening under condition of

power-off, this function needs to be activated. Activation method: Meter keeps continuous power supply for more than 2 hours after delivery from factory; or acaccumulative power consumption with more than 1okWh.

Activation status: Terminal cover opening under condition of power-off, and tripping at recovery of power supply. Meter will recover power supply only after subscriber takes back terminal cover to original position, and input corresponding TOKEN while meter remains balance amount and other problem is free.

Inactivation status: If terminal cover opening under condition of power-off, and meter will not



power off when power supply recovery ( terminal cover has been closed). Such activation will not be applied when delivery from factory as it’s more convenient for electricity company to test and install meters.

Cover opening indication icon:

① continuous lighting: there used to be cover opening event, and terminal cover has been closed and built-in relay tripping.

② flashing: there used to be cover opening event, and terminal cover is still open. Note: It’s decided by meter’s prepayment configuration word to allow cover opening detection under condition of power-off or power-on.

8.6 Pre-warning & warning against low balance amount

This function is applied to prompt subscriber that the balance amount is not sufficient, and recharge is necessary; otherwise, meter will cut off power supply once balance amount uses up soon later, and will bring subscriber inconvenience. Furthermore, this function provides subscriber choices for settings. One hand, subscriber can reset threshold value of balance amount for pre-warning/ warning according to actual situation; another hand, subscriber can reset audible warning or not.

8.6.1 Pre-warning function When balance amount is lower than threshold value for pre-warning(OBIS code C.51.12), meter

will sound warning and yellow LED indicator will flash, and icons 、 will alternatively flash

on LCD screen display to prompt subscriber to purchase electricity. It’s programmable to set threshold value for pre-warning and its relevant function by inputting code: 4547 8xxx, available value is from 1-999$. CIU screen will display “Accept” ,and indicate successful settings.

Pre-warning threshold value for This project: 30.00$

Warning indication details:

Red warning indicator keeps continuous lighting ----- it means balance amount is lower

than 30$；

Red warning indicator flashes ----- It means balance amount is lower than 20$；

Red warning indicator flashes and sounds warning ----- It means balance amount is

lower than10$；



8.6.2 Warning function When balance amount is equal or lower than threshold value (OBIS code C.51.11), meter sounds warning, yellow LED indicator keeps continuous lighting, and meter’s internal replay disconnects

to cut off power supply. Icons 、 will alternatively flash and icon will display on

LCD screen. subscriber has to press blue key on meter keypad for recovery of power supply if any inquiry. It’s programmable to set threshold value for warning by inputting code: 4547 9xxx, available value is from 0-999$. CIU screen will display “Accept” ,and indicate successful settings.

Warning threshold value for this project : 0.00$

Note: Threshold value for warning must be lower than threshold value for pre-warning; there will

no corresponding warning or pre-warning if threshold value for warning or pre-warning is set as

zero. It’s very convenient for subscriber to programme the settings and relevant function.

8.7 Anti-overflow when recharging It’s allowed to set upper limit for subscriber maximum consumption amount( OBIS code C.50.4). If TOKEN is valid, but balance amount will be higher than upper limit after recharging, then meter will reject the TOKEN. It can be available to have normal operation only when balance amount( after recharging) is equal to or lower than upper limit.

Threshold for Maximum recharging amount 999999.99$

8.8 Anti-tamper for reverse power consumption. Meter will cut off power supply circuit when it detects reverse power consumption. L line and N line are reverse in terminal connection. Meter will detect this event, and will automatically cut off power supply if reversing event keeps over 60 seconds. Meter will automatically recover power supply 5 minutes later when grid resumes work in proper way; or press keypad to recover power supply within 5 minutes when grid resumes work in proper way ( it will be invalid to press in the first minute, and valid since the second minute). Note: It’s selected by prepayment configuration word to cut off power supply or not when reverse



power consumption event occurs. Default setting at factory for this project: meter will cut off power supply circuit when reverse power consumption event occurs.

8.9 Overdraft (Option) Overdraft( default settings at factory will not allow overdraft): Meter will support overdraft. Metering administration department or electricity utility can apply such function to subscribers who have higher credit rating. Overdraft will be allowed when threshold is not zero(OBIS code C.50.5). Overdraft amount is equal to threshold value( OBIS code C.50.5). Threshold value consists of six integers and two decimals. When overdraft is allowed(threshold setting - OBIS code C.50.5), and balance amount is lower than threshold for pre-warning or balance amount is zero which results in power-off, subscriber can input short code 8989 8686 to activate overdraft function so as to continue power supply until available overdraft amount become zero. Note: Overdraft function is temporary measure for subscriber when it’s not convenient to purchase electricity. subscriber should go to purchase electricity ASAP when overdraft is working. Default setting at factory for this project: without overdraft function

8.10 Power-off upon load current higher than threshold

(Option) When one- phase current is over threshold( check OBIS code 11.35.0), LCD screen will sound warning and yellow LED indicator will flash; meanwhile, LCD will display overload current information, and timely shift to display present real-time current.

（( display shift)

If current value keeps higher than threshold within 45 seconds, meter built-in relay will cut off power supply at the 45th second, and power-off will The last 150 seconds; then built-in relay will automatically recover power supply(subscriber can not manually recover power supply within 150 seconds). Meanwhile, LCD will display remaining time information for recovery(unit: second; it means locked remaining time. Remaining time will descend by interval of 1 second based on the locking state). And LCD will timely shift the display for overload real-time current before power-off.



(display shift)

If subscriber doesn’t low down consuming current, and continue to allow current over threshold, the process will repeat. Meter will automatically recover power supply after 30 minutes delaying provided that overload current results in 5 times successive tripping within 30 minutes. subscriber can not manually recover power supply during 30 minutes delaying. In the locking time, LCD will display locked remaining time which will descend by interval of 1 minute; meanwhile, LCD will display the current at the last time power- off . It’s programmable to set delaying time for recovery after 5 times successive tripping; Minimum setting value: 5 minutes; default value at factory: 30 minutes. Current threshold for this project: OA don’t ask for this requirement!

Note: when meter suffers from successive tripping with overload current, subscriber should check

the current, and contact electricity company to modify threshold so as to keep subscriber’s

normal power consumption.

20 Instruction for prepayment keypad meter power load threshold presetting & pre-stored electricity at factory 20.1 Rule for load threshold presetting & pre-stored

electricity at Factory by INHEMETER massive production DTZ1513 three phase CT/PT connected keypad prepayment energy meter:

Pre-stored electricity：30.00kWh

Load threshold ：22.000kW

Preset pre-warning alarm threshold：30.00kWh

Preset alarm threshold：0.00kWh

20.2 Pre-stored electricity It aims to test before installation, check the circulation status after installation. There several modes regarding pre-stored electricity. Detailed operation will refer to local practice.



A: After finishing the test before installation, installation operation and circulation status check after installation, the pre-stored electricity can be reset to zero by installation worker before officially handing over to users. Carry-out ways: In the stage of installation, while registering user and meter information in the power vending system, the system will generate the TOKEN code specialized in clearing up power consumption credit. After finishing the circulation check status and before officially handing over to users, installation workers will input this TOKEN code into keypad prepayment energy meter to clear up power consumption credit (clear up pre-stored electricity). B: After completing measurement meter testing, installation and inspection of electricity circulation status after the installation, energy meter can be formally delivered to users in the prior record by a meter installer residual value of the stored power to submit the sale of electricity management system. Specific carrying out ways: After completing measurement meter testing, installation and inspection of power after the installation, energy meter can be formally delivered to users in the prior by a meter installer record residual value of the stored charge and get the user to confirm it; installer will record the pre-stored electricity meter to log on to the remaining value of the stored power management system for the sale of electricity from the sale of electricity management system in the user when the first purchase deducted. C: Give the pre-stored power to users for free. Since the quantity of pre-stored electricity is not very big, then it can be given to users for free use after energy meter test, installation and circulation statuses check. D: The pre-stored power will be deducted with one time by power vending management system. According to pre-stored power in the energy meter before delivery, power vending management system will deduct it while users open an account and purchase the power.

20.3 Load threshold presetting The purpose of pre-set load threshold is to facilitate measurement test before installation of energy meter. According to the user information and load threshold permitted by utilities, the special load threshold TOKEN code will be generated by the power vending management system, and then users input it into related energy meter to finish load threshold setting. In the process of using the meter, if the actual load of users changes, then they can apply for load threshold change anytime. If the application is authorized, the specific TOKEN code used for load threshold will be generated by power vending management system, then users input this TOKEN to the related meter and finish load threshold changes.



21 Keypad prepayment meter massive production encryption key setting and process 21.1 Customized SGC Code Setting

Encryption Key for this project: SGC 600434,01,1

Energy meters are set according to the client’s requirement for SGC. A series of operation like

installation, power vending, recharging, etc. can be processed once the client receives the

products.

When leaving factory, INHEMETER keypad prepayment energy meter’s meter number, factory setting and other information are given together with the whole batch. It’s convenient to import all the information to customer vending management system.

21.2 INHEMETER default encryption key（SGC：999937）

Setting Set with the default factory encryption key (SGC: 999937)-key type is DDTK.



Encryption key will be replaced as follows: 1. INHEMETER provides a authorization table with the SGC code: 999937 and manufacturer’s information of INHEMETER as table 1. 2. Customer fill in the vending security module number, customer information (as table 2), submit the table to the Key Management Center（KMC）and apply for a key file of the keypad prepayment energy meters of INHEMETER, then update their security module. 3. Energy meters will be set with the SGC: 999937 of INHEMETER, and can be supplied to all customers who have this requirement, key on the back plate is as the follow diagram.

4. After customer receive energy meters from INHEMETER, they should generate 2 groups of

replace TOKEN codes as per new security modules, input them into the energy meters, so as to change the default keys（DDTK）to unique keys （DUTK）, the back plate has to be replaced too.
