Chapter 6 • Advanced Features
The rules for the lockout feature are detailed in the following table.
When a lockout state is ON, no further UTRN entries are allowed. Any such
entries will be rejected until the next top-of-the-hour is crossed.
Maximum Meter Balance
The maximum meter balance is the absolute maximum amount of credit that is
allowed to be credited to the meter balance.
If a top-up via a UTRN takes the credit above this threshold, the UTRN token will
be rejected, but the consumer will be able to apply that UTRN again when the
meter balance has sufficiently dropped to allow that top-up.
Maximum Credit Threshold
The maximum credit threshold is the absolute maximum amount of credit from a
single transaction that is allowed to be added to the meter.
If a top-up via a UTRN exceeds this vend amount, an invalid response will be
generated, and the UTRN token will be rejected.
Debt to Clear
The ESME will display the minimum amount of monies required to clear the
current debt to achieve the following two goals:
1.
Allow the consumer to get back on supply if previously disconnected
2.
Allow the consumer to have EMC available again if previously used
N
OTE
Consumers can ‘live’ in EMC.
The determination of the debt to clear is as follows:
Debt to Clear = ((Disablement Threshold – Meter Balance) + EMC Used +
|Accumulated Debt|) * 100/(100%)
N
OTE
% is the payment recovery off a top-up.
