Technical Description

5.4 Alarm

The purpose of the alarm function is to enable monitoring of quantities in the
General
meter. Monitoring can be set to high or low level detection. High level detection
gives an alarm when the level of a quantity goes above the set level. Low level
detection gives an alarm when the value goes below the set level.
It is possible to configure 25 alarms. Configuration can be done via communica-
tion or with the buttons directly on the meter.
Depending on the meter type all or a subset of the following quantities can be
Quantities
monitored:
Voltage L1
Voltage L2
Voltage L3
Voltage L1-L2
Voltage L2-L3
Voltage L1-L3
Current L1
Current L2
Current L3
Current N
Active power total

When the value of the monitored quantity passes the activation level, and remains
Functional
there for a period of time equal or longer than the specified time delay, the alarm
description
is activated. In the same way, the alarm is deactivated when the value passes the
deactivation level and remains there for a time equal or longer than the specified
time delay.
If the activation level is higher than the deactivation level, the alarm is activated
when the value of the monitored quantity is higher than the activation level.
If the activation level is lower than the deactivation level, the alarm is activated
when the value of the monitored quantity is lower than the activation level.
