intervention to free up memory. The memory full event is classified as a critical priority event
by default. The meter will send a notification message via the AMI signal.
Resetting Time of Use Accumulation Registers
The SGM3000 Series meters support a reset to zero (0) of all TOU accumulation rates. The
meter will not support a reset of an individual TOU rate. All TOU data will be reset
simultaneously.
The reset of the TOU rates will trigger local recording of the accumulated data
in all TOU rates. The meter will maintain a count of the number of TOU rate resets.
3.4 Prepayment Operation
The SGM3000 Series meters operate with prepayment conditions where funds for energy have
been paid in advance. The meter will maintain the available funds independently for each phase
of the meter. The value of the funds available will depreciate as active energy is consumed. The
price of energy is driven by the current TOU pricing established for the phase.
The meter will generate a low funds event when the available funds are less than a defined
threshold. The low funds event is classified as a critical priority event by default. The meter will
send a notification of the date and time of the funds falling below the threshold when the event
is generated.
The meter will generate a funds exhausted event when the available funds are zero (0). The
funds exhausted event is classified as a critical priority event by default. The meter will send a
notification message via the AMI.
The meter supports the receipt of additional funds to add to the remaining funds and an event
will be generated when the funds are added. The additional funds event is classified as a critical
priority event by default. The event will include the amount of funds added to the meter. The
meter will send a notification message via the AMI signal.
Overdraft Facility
The SGM3000 Series meters support the configuration of an overdraft limit that will be added
to the available funds for the purposes of triggering a supply disconnection.
Critical Peak Pricing
The SGM3000 Series meters support Critical Peak Pricing (CPP). The meter will have a
configuration for identifying a time of use rate to use when a CPP period is activated. Any of the
available TOU rates can be used for CPP periods.
The meter supports the receipt of a critical peak-pricing (CPP) event. The CPP event notification
will include a start time and end time for the event. The CPP event notification will include the
TOU rate in which to accumulate energy during the CPP period. The CPP event will not operate
on a schedule with a calendar like regular TOU data. CCP is used as an override for network
critical periods.
