•
7 configurable TOU energy registers for accumulating kWh
(import and export), kvarh (import and export), kVAh and energy
from two external meters through 2 pulsing inputs
•
3 configurable TOU Maximum Demand registers for recording
maximum kW (import and export), and kVA demands
•
16
tariffs
•
16 daily profiles (e.g., 4 seasons, 4 daily profiles per season)
•
8 daily tariff start times (tariff changes)
•
2
calendars
•
automatically configurable daily and monthly TOU profile log
for each allocated energy and maximum demand register using
season energy tariffs
A
0.5 Megabyte
onboard non-volatile memory is provided for data, event
and waveform recording.
•
Event recorder
provides logging configuration
changes, resets, device diagnostics and setpoint
operation events.
The event-driven
Data recorder
is provided for recording user-selectable
data in up to 8 data log files on a periodic basis or on any internal and
external trigger. It can be used for load profile and TOU energy profile
recording, or to log fault data on alarm conditions or digital input changes.
For more detailed information on event and data logging, see Appendix D.
Fast
Waveform Recorder
is provided for waveform capture and logging
on different events. Along with the disturbance monitor it allows for
capture and recording of various types of disturbances with a duration
from one millisecond and up to tens seconds - transients, outages, sags,
surges and deviations in voltage level.
User-selectable options
are provided (see Section 4.11):
•
Two power calculation modes
•
Programmable energy rollover value
•
Phase energy calculations option
•
Harmonic power/energy calculation option
