5.4 Configuring Billing/TOU
The TOU battery-backed clock unit is highly recommended in case
of using time-scheduled tariff rates, otherwise a long power
outage may cause the meter clock to lose time so your tariff
counters would not comply with the calendar schedule.
Billing Energy Registers
The PowerSmart+ PQME/EH has 4 fully programmable billing energy
registers that can be linked to any internal energy source or to an
external pulse source that delivers pulses through the meter digital inputs.
Any energy register can provide either a single-tariff energy accumulation
or be individually linked to the TOU system providing both total and multi-
tariff energy billing.
Tariff Rates
The meter tariff structure supports 8 different tariff rates using an
arbitrary tariff schedule. A total of 4 types of days and 4 seasons are
supported with up to eight tariff changes per day.
Maximum Demand Registers
Any of billing energy registers can be individually linked to the maximum
demand register providing the same demand tariff structure as you
selected for energy registers.
Recording Billing Data and Load Profiling
The PowerSmart+ PQME/EH can provide automatic recording of the daily
energy and maximum demand profile to a data log file. Maximum demand
profiling can be individually configured for every register.
See Factory Preset Data Log Files in Chapter 5 and Billing Profile Log File
in Appendix E for more information on the file layout and contents.
To configure the billing registers and the tariff system in your
meter:
1. Link the billing registers to the respective energy sources.
2. Configure the options for the registers to whether the only
totalization or both total and tariff registers would be used, and
whether daily profiling should be enabled for the energy usage
and maximum demand registers.
3. Configure the daily tariff schedule using the TOU daily profiles for
all types of days and seasons.
4. Configure the season tariff schedule using the TOU calendar.
Configuring Billing/Tariff Registers
To configure the billing/TOU registers in your meter:
1. Select Energy/TOU from the Meter Setup menu.
