D000044352 en g – E230 Residential Electricity Meter – ZxR100xC/ZMR100xR – User Manual
If the meter is configured to operate in Reverse Energy fraud detection
mode, the meter will alternate a warning message on the display if a
fraud attempt is made by running current backwards through the meter.
The reverse energy warning message is triggered when the reverse
power exceeds a programmable threshold level of between 1-10 Amps
for a period of 10 seconds. The meter will store the number of RED
(Reverse Energy Detected) tamper events.
Once triggered, the reverse energy-warning message can only be reset
by a formatted command.
All meters with an internal RTC have a tamper event log, where the
date/time, status and number of events are stored. The maximum
capacity of the log is 200 events. The event log can be read and cleared
through the communication interfaces with appropriate rights, but it is not
displayed on the LCD.
The following events can be recorded in the log depending on the device
settings and configuration. The events trigger a log event either when
they begin or both when they begin and end.
Description
Indicates that any phase
voltage is below the %
threshold of Max Voltage.
Indicates that tariff energy
registers were cleared (but not
the total energy registers).
Indicates that the load profile
and/or the stored value profile
was cleared.
Indicates that the event log
was cleared. This is always the
first entry in the event log.
Indicates that the battery
voltage fell below a set
threshold.
Indicates that any phase
current is below the %
threshold of Max Current.
