Alarms and alerts

Alarms

An alarm is the meter's means of notifying you when an alarm condition is detected, such as an
error or an event that falls outside of normal operating conditions. Alarms are typically setpoint-
driven and can be programmed to monitor certain behaviors, events, or unwanted conditions in
your electrical system.
You can configure your meter to generate and display high, medium, and low priority alarms when
predefined events are detected in the meter's measured values or operating states. Your meter
also logs the alarm event information.
The meter ships with some alarms already enabled from the factory. Other alarms need to be
configured before the meter can generate alarms.
Customize meter alarms as required, such as changing the priority. You can also create custom
alarms using the advanced features of your meter.

Alarm types

Your meter has five types of alarms:
Alarm type
Setpoint
(standard)
Digital
Disturbance
(sag/swell)
Transient
Unary
Alarms have two states:
Alarm state
Active
Historical
For more information on Setpoint, Relative Setpoint, Digital Input, Disturbance Analyzer,
Transient, and Sag/Swell modules, see ION Reference, available on www.usa.siemens.com/pds.

Standard and high-speed alarms

Alarm speed is determined by the update rate of the framework for the particular alarm.
7EN05-0390-08
Description
Setpoint alarms compare the actual value of a parameter to a specified limit
or range of values. These include measured voltage and current values and
calculated power quality values.
Some setpoint alarms use high-speed measurements for up to 1 millisecond
resolution.
Digital alarms are triggered on a digital input's on/off state.
Disturbance alarms are triggered on a measured sag or swell.
Transient alarms are triggered on a measured transient event.
Unary alarms are not configurable and generate an alarm based on the
meter's state, for example, the meter powering up.
Description
The meter detects the alarm condition is met.
The alarm condition previously existed but the condition has since returned
to a non-alarm state.
