the friendly period. Friendly periods may differ on each day type. If prepaid
credit reaches zero during a friendly period the contactor will remain closed
until the end of that period.
If prepaid credit reaches zero during a friendly period the meter will
continue to charge for energy consumed at the appropriate PPU rate.
Charges will be shown as a debt value in the present balance display.
The 'friendly' periods can be set either by the factory or configured by
optical port or configuration SMS message.
The prepayment mechanism for this meter is Tokenless. However for sake
of convenience each utility customer will receive a magnetic card for means
of account identification. The utilities information system will use the
magnetic card to identify the meter and customer, i.e. when the customer
purchases credit at a POS.
The card will contain a 19-digit number, which is programmed into the
meter during factory configuration, and transferred to the system during
installation.
The Emergency Credit (EC) facility provides the customer with a preset
amount of credit to maintain supply for a short period after credit has been
exhausted or is very low. The EC facility has two parameters; EC
Availability Point [range £0 to £99.99] and EC value [range £0 to 99.99].
When the Present Balance register value in the meter falls below the EC
Availability point, EC shall become available for use. The display will signify
that EC is available by showing the character E at the end of the display,
see Display section.
If EC is available and the EC button is pressed, the EC value is transferred
to the Present Balance Register.
If the Present balance register contained a positive value, the EC

allowance shall be added to this value in the Present Balance
register.
If the present balance register contains a negative value (debt) the

register will be reset and overwritten with the EC value. The Debt
value will be written into the Debt to clear register. The meter will
automatically display the debt to clear register as the first display in
the display cycle.
