64 Meter Operation
energy values are stored as totals into the four tariff registers based on the TOU
schedule.
The available options of the perpetual TOU calendar are:
Day schedules (per season):
o 1 weekday schedule
o 1 Saturday schedule
o 1 Sunday schedule
o 2 holiday schedules
4 seasons with programmable start dates
15 holidays per year
1 independent self-read schedule per year
10 tier switches per day
1 date for DST on, 1 date for DST off, with programmable time and minutes
adjustment. DST on and off can be set to occur at different times of the day
The meter will store the following values, per tariff:
Active energy, forward and reverse
Active energy, forward + reverse
Active energy, forward – reverse
Reactive energy, import and export
TOU Calendar Identifier
When a new calendar setup is created, using either NES System Software or the
NES Provisioning Tool, a corresponding numerical identifier can be set. This TOU
Calendar ID is downloaded to the meter at the same time as the calendar. The TOU
Calendar ID can be selected to appear on the meter display to show the Time-of-Use
calendar that is presently operating.
Pending TOU Calendar
A second TOU calendar schedule can be programmed into the meter. The meter can
be programmed by NES System Software to switch over to the second TOU schedule
on a preset future date and time.
Load Profiles
The meter load profile data log can be configured to record up to 16 different energy
values at once. The load profile log is divided into groups of data called blocks. You
will specify the duration of each block by setting the number of intervals per block, as
well as the length of each interval.
You can also specify the start time for each load profile block. When doing so, you
should be aware that if the total block time (i.e. the interval duration multiplied by
number of intervals per block) does not divide evenly into 24 hours or is not a integer
multiple of 24 hours, then the actual block start time will not always match the
configured block start time. For example, if you have a block start time of 00:00 and
a block duration of 18 hours, then the actual block start times will rotate through
these times: 00:00, 18:00, 12:00, 06:00.
