Status information is also stored with each integration:
•
Load profile event indication with time and date stamps – Power up, Power down, Time
change, Configuration change, New day, Daylight savings, Forced end of demand.
•
Load profile status indication per period – Transient reset, Time synchronisation, Data
change, CT ratio change, Internal battery failure, Reverse run, Phase failure (one or more
phases).
When storage is full, new data overwrites the oldest stored data.
Using Data Stream Mode (9600 baud rate), 90 days of single channel, 30 minute demand period
data can be read in less than 30 seconds.
Two methods of reading load profile data are provided:

Load profiles can be transferred to the Power Master Unit and viewed in Readings.
