TIME OF USE (TOU) SETUP
Four rate periods are supported for Time Of Use (TOU); A, B, C, and D in addition to total rate
(which is independent of time of use).
At the start of a new demand interval, the Power Xpert Meter updates the TOU demand registers.
If a scheduled rate change occurs, the demands are updated before the new rate is applied. The
TOU schedule changes the rate and initiates a new demand window. The next demand window
uses the new rate.
The meter will support up to 64 rate schedules with day types of weekdays and weekend. Time of
Use defines the Rate Schedule and the Calendar for the meter.
Rate Schedule Setup
The Power Xpert Meter has up to four user definable rate schedules. You can define the rate as a
weekday or weekend and select the time the rate schedule is to begin. The rate schedule’s ending
hour is defined by the beginning of another rate schedule.
For example, Rate A is defined as a weekday beginning at 7:00 A.M. and ending at 4:59:59 P.M.
when Rate B begins at 5:00 P.M.
