E470 Tokenless Smart Prepayment Meter
Issue: 1.8
The meter may operate a time-of-use tariff, a block tariff within a billing
period or a combination of the two. This section describes the operation of
the different tariff structures that may be applied to the meter.
The TOU scheme will provide switching across four TOU rate registers.
The scheme will hold up to 15 time switches; each time switch will allow
switching to be applied to any day of the week. Additionally each time
switch will enable the auxiliary control relay to be closed. Upon reaching a
time switch with an auxiliary relay close command, the relay will close and
remain closed until the next time switch.
The TOU tariff scheme will allow seasonal switching such that switching
times can be different for summer and winter periods.
Seasons may be set to:
Summer (S) Operate from last Sunday in March to last Sunday in October.
Winter (W) Operate from last Sunday in October to last Sunday in March.
All Year (A) Operates throughout the year without any seasonal changes
A diagram of the full rate-switching scheme is given below.
