7.3: TOU Frozen and Active Registers
Q
The Nexus® meter stores accumulations for the prior time periods. When the end of a billing period
is reached, the Active period of time becomes stored as Frozen. The registers are then cleared and
accumulations resume, using the next set of TOU schedules and register assignments from the stored
calendar.
Q
Frozen and Active Accumulations are always available.
7.4: Updating, Retrieving and Replacing TOU Calendars
Q
Communicator EXT software retrieves TOU calendars from the Nexus® meter or from the
computer’s hard drive for review and edit.
Q
Up to a maximum of twenty yearly calendars can be stored in the Nexus® meter at any given time.
You may retrieve them one at a time; a new calendar can be stored while a current calendar is in use.
Q
Accumulations do not stop during calendar updates. If a calendar is replaced while in use, the
accumulations for the current period will continue until the set end date. At that point, the current
time will become the new start time and the settings of the new calendar will be used.
Q
Reset the current accumulations, if you replace a calendar in use. A reset clears only the current
accumulation registers. This causes the current accumulations to use the present date as the start and
accumulate to the next new end date, which will be taken from the new calendar. Once stored, prior
accumulations are always available and cannot be reset. See the
Communicator EXT User Manual
for instructions on resetting current TOU accumulations.
Q
At the end of a defined period, current accumulations are stored, the registers are cleared and
accumulations for the next period begin. When the year boundary is crossed, the second calendar, if
present, is used. To retain continuity, you have up to one year to replace the old calendar with one
for the following year.
