If Emergency Credit is enabled when the meter account is in the Low Credit Zone the meter will automatically
start operating in Emergency Credit mode once the Zero Credit threshold is crossed, otherwise, it will continue
to operate in grace period offered by the supplier. The grace period is a limited time given to Users so that they
can add credit or enable Emergency Credit. At the end of the grace period the supply will be disconnected if
Emergency Credit is not enabled or credit has not been added to the meters account, provided the meter is not
operating in a Friendly Credit period. To reconnect the supply after a supply disconnection, the User must either
enable Emergency Credit (if not already used) by pressing key 'A' on the meter keypad or the appropriate
button on the IHD or add more credit to the meter. Enabling Emergency Credit or adding more credit after a
supply disconnection will change the meter's switch to a 'READY' state. The meter displays the message
'PRESS A' to begin the supply restoration process. Pressing key 'A' on the meter's keypad causes the meter to
display the message 'PRESS B'. Pressing key 'B' on the meter's keypad confirms the supply restoration
process resulting in the switch being closed. During the period for which the supply is disconnected, standing
charges will apply and accrue if configured to do so. The accrued standing charges, if disabled, will not be
deducted from the Emergency Credit allowance thus allowing the user to have use of all the Emergency Credit.
They will however accrue and will be deducted when the meters account is above the Zero Credit threshold.
5.5.4.3 Emergency Credit Zone
In the Emergency Credit Zone the value of the meter account, after a reduction, is checked against the meter's
Low Emergency Credit threshold. No action is taken if the value is above the threshold. A visual indicator on the
meter display as well as on the IHD will indicate when Emergency Credit is in use. In addition, the meter
provides information on the Emergency Credit amount remaining. If the meter is configured not to collect
standing charges from Emergency Credit, the meter will maintain, in a separate register, the standing charge
amount that would have otherwise been deducted during this period. The accrued standing charge will be
recovered in full from the top-up amount before Emergency Credit is made available for use again.
When the value reaches the Low Emergency Credit threshold or the entire Emergency Credit allowance is used
up, the meter will send an alert to the IHD and if configured generate a local visual and audible alert to the user
subject to restrictions detailed in the Friendly Credit section of this manual.
If the entire Emergency Credit allowance is used up but the meter is operating in Friendly Credit period, the
supply will remain On till Friendly Credit ends. At the end of Friendly Credit, if no credit has been added to the
meter's account the User is given an Emergency Credit grace period to add more credit to the meter's account
after which the supply is disconnected and will not reconnect even at the start of the next Friendly Credit period.
The meter will display the top-up amount to be repaid which will include the full Emergency Credit amount
together with additional applicable standing charges and any unpaid debt. The user must add sufficient credit to
put the meter's account into positive balance before supply restoration is permitted.
Note: Standing charges and unpaid debts will be deducted from the Emergency Credit allowance if the meter is
configured to do so.
5.5.4.4 No Credit Zone
In the No Credit Zone there is no Emergency Credit left to be used by the user; therefore, the supply will remain
disconnected until the User tops up the meter's account sufficiently to repay the used Emergency Credit
including any unpaid standing charges, leaving the meter's account in credit.
Note: Users can mute audible alerts by pressing key 'B' on the meter or acknowledging them on the IHD.
