List of events
© Landis+Gyr AG
Events that occur sporadically are stored in the event log. The user may
select which events trigger an entry in the event log. The event log is used
to analyse the behaviour of the network as well as to supervise the correct
function of the meter.
In the event log, a maximum of 500 event entries can be stored. The
individual entries consist of the time stamp and the event number.
Additional information such as the error register or energy total registers
can also be stored with every event.
The event log is organised as a circular buffer, i.e. the oldest entry will be
overwritten by the most recent entry.
Network quality events, can be stored in the dedicated event log. The
dedicated event log consists of three groups of logs.

Overvoltage events

Undervoltage events

Missing voltage events
In the dedicated event logs, important information can be stored per entry
such as:

duration of the events

extreme values of the events (not for missing voltage).

instantaneous values

maximum three energy registers
Additional information can be read from the header of the event logs, such
as the longest entry, the shortest entry, the total number of occurrence and
the total duration of the event.
The dedicated event logs are organised as circular buffers, i.e. the oldest
entry will be overwritten by the most recent entry.
The table below lists all events which can be captured in the event log.
Depending on the parameterisation, some events may never occur.
Events which can be stored in the dedicated event log are marked in the
corresponding column.
