Memory functions
11.6
Event memory
The event memory saves 4096 events with date, time and status in a ring buff er.
The following events are acquired:
Event
Recording
Tariff input
Switchover signal HT => LT with date and time
Switchover signal LT => HT with date and time
Sync input
Subsequent synchronization with date and time, informa-
tion on the synchronization type
Power failures
with date, time and duration of the power failure
Error
Error type with date and time
Changed settings/dele-
tions (powerfail entry)
e.g. reset via EBUS / set clock / deletions / parameter
changes leading to deletions
Measuring voltage
failures
If the power is reduced to 85 % of the rated voltage for lon-
ger than 20 ms (can be set using the computer).
NOTE
The memories described can only be read or confi gured via the Energy Bus and
optionally available software (e.g. visual energy).
11.7
Measurement period synchronization
The measurement period of the multimess F144-2-LED-ESMS-...-4 can be
synchronized in four ways, with the measurement period being adjustable. The
measurement period and the synchronization always aff ect all period signifi -
cance values.
The following 4 types of synchronization are possible:
11.8
Synchronization only by internal clock
Synchronization by internal clock is started with the factory reset. From this
start time, the clock will synchronize the measurement period every 15 min-
utes.
