17. PREPAYMENT MODE

This Section describes features applicable to Prepayment Mode only.

17.1. Introduction

The AS302 can be configured to act as Credit or a Prepayment Meter. When configured in Prepayment Mode, relevant
Prepayment Information needs to be configured in the meter.
The main meter functionality remains the same for Credit Mode and Prepayment Mode. The meter will continue to operate
in Prepayment Mode regardless of connection to the WAN.

17.2. Meter Balance - Prepayment

The Meter Balance can be viewed on the display.
The Meter Balance is increased when credit is added to the meter.
The Meter Balance can be adjusted (positive or negatively) by receipt of an appropriate command.
The Meter Balance can be reduced by the following individual factors:
•
Energy usage - Price applicable at the time
•
Recovery of any Debt configured in the meter
•
Recovery of Standing Charge
The Meter Balance is updated every second.
The Meter Balance can be reset to zero on receipt of an appropriate command. This will also reset the Accumulated Debt
and Emergency Credit Balance. An event will be created in the Event Log.
If the contactor is in the Open and Unlocked state, any adjustment to the Meter Balance that causes it to rise above the
Disablement Threshold will Arm the Contactor (the Contactor symbol will flash on the display).

17.2.1. Low Credit Warning

The Low Credit Threshold is a configurable monetary value that is used to alert the consumer that the Meter Balance (and
if activated the Emergency Credit Balance) is low.
The meter issues a Low Credit Warning on the display to the consumer if the Meter Balance (and if activated the
Emergency Credit Balance) is equal to or less than the Low Credit Threshold and sends an alert on the HAN and WAN.
The Low Credit Warning, on the display, is removed if the Meter Balance (and if activated the Emergency Credit Balance)
rises to a value greater than the Low Credit Threshold.
An Audible Alarm can be sounded when the Low Credit situation is entered (This is configurable during the manufacturing
process only).

17.3. Disablement Threshold

The Disablement Threshold is a configurable monetary value used to control the opening of the contactor. The meter
contactor will open if the Meter Balance (and if activated Emergency Credit Balance) is less than the Disablement
Threshold unless scheduled otherwise in the Non-disconnection Calendar. This will create a message on the display and
send an Alert on the WAN.
The contactor cannot be closed by the consumer until the Meter Balance (and if activated Emergency Credit Balance)
rises to a value equal to or greater than the Disablement Threshold.
The contactor will not open if the Meter Balance (and if activated Emergency Credit Balance) is equal to or less than the
Disablement Threshold during periods on non-disconnection as defined by the Non-disconnection calendar. If this situation
occurs an Alert will be sent by the HAN.
See 34.9 for operation of the Disablement Threshold.
