Configuring Billing/TOU
The EM920 provides 10 universal billing energy registers that
can be linked to any internal energy source or to any external
pulse source that delivers pulses through the device digital
inputs.
Any of energy registers can provide either a single-tariff
energy accumulation or be individually linked to the TOU
system providing both total and multi-tariff energy billing.
Any of energy registers can be individually linked to the
maximum demand and cumulative maximum demand
registers providing the same demand tariff structure as you
selected for energy registers.
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.
The first four billing registers in your meter are pre-
configured at the factory to store delivered and received kWh
and delivered and received kvarh. You can change the factory
assignments or configure the remaining registers on your
selection.
To configure billing/TOU registers in your meter:
1. Link the billing registers to the respective energy
sources.
2. Configure the register options, like multi-tariff billing,
maximum demand and monthly/daily profiling, for
every register you selected.
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.
