5.4.2.1 Credit zone
In the credit zone, the value of the meters’ account, after a reduction, is checked against the meter’s Low
Credit threshold. No action is taken if the value is above the threshold. When the value goes below the
threshold, the meter generates an alert.
5.4.2.2 Low credit zone
In the low credit zone, the value of the meter account, after a reduction, is checked against the meter’s cut-
off threshold. No action is taken if the value is above the cut-off threshold. In this zone, emergency credit is
made available to the user before the value reaches the cut-off threshold. A visual indicator on the meter’s
display indicates that emergency credit is available. While the meter is operating in this zone, if
emergency credit (Refer section 5.4.3 for details )is made available, the user can enable it by pressing
key ‘A’ on the meter’s keypad to prevent supply disconnection when the meter reaches the cut-off
threshold.
5.4.2.3 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 will indicate when emergency credit is in use. Also, the meter provides
information on the emergency Credit amount remaining.
If the entire emergency credit allowance is used up, but the meter is operating in friendly credit (Refer
section 5.4.4 for details) period, the supply will remain ‘On’ till friendly credit ends. The user must add
sufficient credit to put the meter’s account into positive balance before supply restoration is permitted.
5.4.2.4 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 the amount which is shown
as –ve balance on the meter.
5.4.3 Emergency credit (EC)
Liberty EG4v12 operating in Prepayment mode supports Emergency Credit functionality which if enabled will
prevent immediate supply disconnection when the meter account becomes zero or negative. Emergency
Credit is made available to users when their meter account passes the Low Credit threshold. A visual
indication on the meter’s display will indicate the availability of Emergency Credit. It can be enabled by
pressing key ‘A’ on the meter keypad. If Emergency Credit is available but ignored by the user previously,
then it can again be availed by pressing key 7 on the meter keypad.
‘Not now’, ‘Selected’, ‘In use’ or ‘Used up’ display will appear on the meter as per the current EC status.
