Prepayment Mode
In Prepayment mode, the SGM1400-B Series meters utilize the credits and
charges detailed below.
Credits
1.
Token Credit Object (Meter Balance)
•
In Prepayment mode, the meter balance represents the amount of credit the
consumer either currently has available (positive amount) or currently
owes (negative amount).
•
Normally, when in credit, this amount will be positive and will reduce as
energy is consumed and charges are imposed.
•
The meter balance is exhausted when the amount falls below the
Disablement Threshold, where the supply will be disconnected except
under the following circumstances:
1
Emergency credit is selected by the consumer.
2
A non-disconnect (friendly disconnect) period is in force.

A Low Credit Warning message will be displayed when the meter balance
falls below the Low Credit Threshold, informing the consumer that they
should top-up. The Low Credit Warning Threshold for meter balance is £2
by default, but it is configurable.
•
When top-ups are applied, this credit (meter balance) will increase, but the
amount will depend on any debts recovered first (i.e., any amount of
emergency credit used, accumulated debt accrued, and payment-based
debt, where configured).

meter balance falls below the configurable Emergency Credit Threshold.

•
When activated, the emergency credit becomes ‘In-Use’ immediately after
the meter balance is exhausted.
•
A Low Credit Warning message will be displayed to inform the consumer
that they should top-up when the emergency credit runs low. The threshold
used is the same as that configured for the meter balance.
•
The emergency credit becomes exhausted when the value reaches zero.
Thereafter, consumption and charges will recommence being levied off the
