Lock-out time
End of billing (EOB) source triggers can also disable other EOB sources from having any effect for the duration of
a pre-configured
lock-out
time. This prevents any further spurious or unnecessary EOB events from occurring.
Using the meter support tool, the lock-out option for each EOB source can be enabled or disabled and the
duration configured.
In addition, interactions between the EOB source triggers can be programmed, as follows:
The latest EOB source trigger can:
have no influence on the lock-out time of a specific source
cancel the lock-out time of a specific source, if it is active
re-trigger a new lock-out time for a specific source - this lock-out time will not be cancelled on a three-phase
power failure
re-trigger a new lock-out time for a specific source - this lock-out time will be cancelled on a three-phase
power failure

Historical buffer registers
The historical buffer register architecture is circular and operates in a first-in first-out (FIFO) fashion.
Meter data stored in the historical buffer registers can be read at any time and used for billing purposes.
However, when all historical buffer registers are full, the oldest data set is overwritten at the end of each
subsequent billing period.
Note:
If the data to be overwritten has not been read, it will be lost.
The meter can be configured to record up to 36 sets of meter data in the historical buffer registers when triggered
by an EOB source.
A typical EOB historical data set comprises the contents of the:
total energy registers (TER)
energy rate registers
demand registers
For each rate:
time stamped maximum demand and excess demand
cumulative maximum demand
time stamped peak demand values (x3)
For the Power Factor (PF) channel:
time stamped min PF
average PF
In addition, other sets of meter data values are recorded, for example:
time stamped min/max:
RMS voltage and current
frequency
meter temperature
aggregate active power (import and export)
aggregate reactive power (import and export)
