Following a CoT/S the meter will be reprogrammed with new tariff plans,
TOU switching as required.
When operating in credit mode a reconnection command may be issued to
enable the electricity supply to be reinstated by the customer.
The command will consist of:
Close electricity meter contactor

Time and date for event or immediate

Acknowledgement request.

At the designated time, and if requested, the electricity meter will allow the
customer to close the contactor. The meter will scroll the message 'Press
Orange button for power' as described in section 6.7. When the consumer
presses the Emergency credit button the contactor will close and supply
restored.
The meter may be configured to record 30-minute electricity profiles; the
meter will store up to 30 days of 30-minute profiles.
Half hourly profiling will commence following the receipt at the meter of a
command from the utilities information system for them to begin. The
command will consist of a profile request, a start and stop date or
continuous. Between start and stop dates the meter will transfer profiles to
the utilities information system at regular intervals [A single days' worth of
30-minute profiles can be packed into a single SMS message].
If continuous profiles are requested the meter will continue to send profiles
until a further command is received communicating a stop date.
If supply is lost to the meter, on reconnection of supply, the meter will
record 'power fail' into the lost profile slots. If the power outage is greater
than 3 days the meter will not attempt to 'pad' lost profiles and will clear the
entire profile log.
