Introduction to Prepayment
Prepayment electricity meters enable supply authorities to collect revenue from consumers more efficiently.
Consumers are obliged to pay for their electricity prior to actual consumption.
This means that if a prepayment meter is installed in the house, the meter would monitor electricity
consumption and compare that to the available credit purchased by the consumer. If the consumer would
exceed this credit limit, the power will be disconnected.
Credit can be added by entering a valid credit token. The credit token must be purchased from the supply
authority or an approved vendor. When a consumer buys electricity from a vendor, the consumer will receive
a receipt with a 20-digit code/token. This token must be entered into the meter in order to credit the
equivalent kWh on the meter.
For Example: A consumer goes to the local grocery store (vendor) to buy electricity. The consumer will
supply the vendor with a meter ID card (or meter serial number) and the amount that he/she wishes to
purchase. The vendor will in return supply the consumer with a receipt with a 20-digit token printed on it.
The consumer will enter this token into his/her meter in the house, and the equivalent amount in kWh will be
credited to the meter. The display of the meter will indicate the amount of credit available in kWh.
1kWh = burning of 100W globe for 10 hours
Vendors from different areas make use of different rates or tariff indexes. This means that each area has a
specific rate at which electricity is charged.
All tokens are meter serial number specific, which means that a token can only be used on one specific
meter. If a consumer buys electricity from a vendor and would for some reason lose the token, no one would
be able to use the token (on a different meter) unless it is entered into the initial buyer’s meter.
Vending systems STS Token
Prepayment meters make use of the Standard Transfer Specification or STS protocol to vend tokens to
meters. This means that any vending authority can vend tokens to a STS compatible prepaid meter. Read
more on STS in the following section.

4
Standard Transfer Specification (STS)
STS is a standardized protocol that enables different vending systems to vend tokens to any STS compatible
prepayment meter.
STS meters
STS Tokens
Vending systems
Itron - Vending system
Vending system A
Vending system B
Tokens generated using this algorithm can only be used once and must be supplied by an approved
authority. Tokens are meter and area specific, which means that a token can only used on one specific meter
and not on any other. Tokens that are lost or stolen can only be entered into the meter that the token was
generated for. This makes the STS prepayment protocol a very safe and controlled environment.
STS allows the use of equipment from different suppliers. It is a secure procedure that prevents the following:
Duplicate generation of tokens through legitimate vending devices
Fraudulent generation of tokens through stolen vending devices
Duplicate generation of tokens through legitimate vending devices outside the supply authority’s
area
Fraudulent use of previously used tokens
Tampering with legitimate tokens (i.e. changing information)
Token security
There are two different types of dispenser tokens used in the STS protocol. These types are: Dispenser
specific tokens and non-specific tokens.

5
Dispenser specific token
Can only be generated by a vending device, which is authorized to vend to the intended meter range.
This means that tokens:
Can only be accepted by the meter, which it is intended for.
Cannot be modified after the tokens have been issued to the user.

Non-specific Token
These tokens are special tokens that are vended from vending authorities and have the following
characteristics:
Can be generated by any vending device, which is authorized to vend credits
Can be accepted by any STS meter
Can be used repeatedly on any STS meter.
Please see the STS User Guide for more information concerning the STS protocol.

These tokens are mainly used to perform maintenance checks on meters. Examples are: ’Display Tariff
Index’ token and ‘Test display token’.

6
Purchasing a token
The vending of prepayment electricity tokens is a one-way system in which tokens cannot be refunded upon
returned. This is because once a token has been issued, the only way that the supply authority could verify if
the token has been entered into the meter is to physically check the meter registry on the meter.
The user purchases credit tokens from a vending authority using the supplied user I.D card and the amount
the user wishes to purchase.
The 20-digit token is generated combining various elements such as the meter serial number, supply group
code and the date on which the token was vended.
When the user I.D card is not available or supplied, it is still possible to purchase electricity supplying the
vending authority with one of the following:
Meter serial number
Stand or property number
Name of property owner
Physical address
The receipt will look similar to the one below:
When the users purchases a token from the vending authority a receipt is handed to the user displaying the
following information
Receipt number
Date
Time of transaction
Monetary value of the transaction
Kilowatt-hour (units) received
20-digit token
Name of consumer
Address
Tariff type
Tariff index
Meter serial number

Meter programmable features
The EM512 TYPE 700 JV1 product is equipped with programmable features, which can be customized to
each customer’s specific needs.
Audible Low Credit Warning and Credits Indicator LED
When the credit available on the meter reaches the low credit threshold, the meter will signal this by change
the color of Credits Indicator LED from Green to Red (Blinking).
The value at which the Low Credit Threshold would enable can be set with a token. This feature can be done
onsite with a token supplied to the user. This token can work on any meter.
The Audible Low Credit Warning is a programmable feature, which will warn the user of a low credit level by
making an audible beep sound, the beep of sound more louder when the credit near to zero.
This is in addition to change the color of LED credit. This feature cannot be changed with a token.
User Programmable Features
The programming or setting of these features can be done by the user in the field
Low Credit Threshold
The Low Credit Threshold can be setting by using short code 456XX, where the XX is energy in kWh
(minimum 05 kWh)
Example:
The low credit = 20 kWh
Programmable interval Buzzer time
When the credit reaches the limit value is low, LED indication green turns to red flashes and buzzer
sounds, the sound can be stopped by pressing any key on the keypad.
If in XXX minutes later, no credit token is entered, the buzzer sounds again. The lower the credit
token so the faster the duration of sound.
The XXX minutes at the sound of buzzer can be adjusted by using short code 123XXX, where the
XXX is the time in minutes
Example:
The interval Buzzer time = 10 minutes

Negative Credit
When the meter credit reaches zero, the meter automatically disconnects the power supply to the house until
a credit token is entered. The EM512 Type 700 JV1 programmed with negative credit. This means that when
zero credit level has been reached and the contactor does not disconnect due to tampering or any other
reason, the meter will display negative credit. When a token is entered, the negative credit displayed on the
meter will be subtracted from the token unit value.
Tamper Switch
The EM512 Type 700 JV1 assembled with a tamper switch. The switch is toggled when the terminal cover is
removing from the meter base. The meters automatically record the numbers of the terminal cover opened
and not disconnect the contactor.

CLEANING THE METER
To clean any meter within the EM512 TYPE 700 JV1 product range it is best advised to use a soft cloth
damped with methanol. Wipe cloth gently across cover of meter. This should be repeated until the meter
cover has been cleaned. The meter cover must be wiped off gently once a month. This is to avoid any
build-up of dust that could effect the meter operation.
Cleaning methods to be avoided
DO NOT use a sharp object to clean the meter as it can scratch the surface of the cover;
DO NOT use a soaked cloth on the meter as it could damage the meter functionality;
DO NOT splash any wet substances on the meter;
