Theoretically, a PLC concentrator can read or control 1024 pieces PLC meters under the same low
voltage transformer. In real situation, only 100-600 pieces meters are installed under a low voltage
transformer. PLC meters produced by INHEMETER have relay function so the PLC
communication distance between meter and concentrator can reach 1,000m. The repeater
installed in special region can improve efficiency of meter reading. Please refer to “Low Voltage
PLC Concentrator Operation Manual” for details.
Meter circuit design, structure design and selection of components and materials are according to
the greater environment tolerance to guarantee the lasting and stable operation of meter. Metering
components take shielding and protection measures in structure design to resist interference of
external DC and AC magnetic field, over-voltage and high frequency electromagnetism field.
Energy meter is with good electromagnetism compatibility. These designs guarantee metering
reliability and stability. Therefore, no more calibration is needed in its life cycle.
Meter cover is made of fire retardant, flame resistant and heat deformation resistant polycarbonate
material. It can be recycled after the end of its life cycle to protect the environment. MCU cover is
double insulated and in compliance with dust and water protection standard IP54 (IEC60529).
MCU terminal is made of brass, and plated with nickel,the same as that for energy meter in
tropical areas. MCU has terminal cover and fastened by a sealing screw.
Keypad Prepayment Meter has two settlement modes: energy deduction mode and money
deduction mode
Energy Deduction Mode:
Shenzhen Inhemeter Co., Ltd
www: inhemeter.com 11
Three Phase Keypad Prepayment Energy Meter
(Plug-in Module Type)
The meter will realize the prepayment control function through the actual energy recharged every
time.
Money Deduction Mode:
The Keypad Prepayment Meter can store the preset tariff (TOU tariff or step tariff). For every
purchase, the vending system will generate a TOKEN, according to the after-tax amount paid by
the user. Then the user input the TOKEN into the meter. The remaining credit will be displayed in
money. The amount will be deducted after 0.01 kWh is consumed, as per the preset tariff rate.
For meter without overdraft function, when the remaining amount becomes zero, the power
supply will be cut automatically.
Money settlement----TOU tariff application instruction:
The vending system will generate a TOKEN as per the after-tax amount paid by the user. Then
the user input the TOKEN into the Keypad Prepayment Meter. The amount will be deducted
according to the actual monthly consumed energy and agreed TOU tariff which is set by
communication port. When the remaining money becomes zero, the power supply will be cut
automatically. 4 tariff rates and 12 time shifts can be pre-programmed each day. Electricity price
will be adjusted according to time period to encourage electricity usage at offpeak period and
save at peak period.

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.
5.4.3 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.

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.

5.4.6 Confirmation 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:
5.4.7 Tariff Table Switching
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 tariff 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
Shenzhen Inhemeter Co., Ltd

5.6 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.

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.
