9410 series Alarms and alerts
The meter records the date and time when the alarm event starts (EV1) and when it
ends (EV2). The meter also performs any task assigned to the event, such as
operating a digital output. The meter also records minimum values (Min1, Min2)
before, during or after the alarm period.
Disturbance (sag/swell) alarms
These alarms are triggered by voltage and current disturbances.
You must configure nominal voltage and current for these alarms to function.
For voltage disturbances, enter the percentage deviation from the nominal that defines
a sag or swell.
For current disturbances, enter the percentage deviation from the nominal that defines
the pickup and dropout points for a current sag or a current swell.
Digital alarms
These alarms are triggered when the associated digital input changes state.
You can configure the alarm to be active when the digital input is on or off, depending
on the alarm’s purpose.
For example, if you used a digital input to monitor a breaker that is always supposed to
be on, you would set the alarm to be active when the breaker has tripped.
NOTE: To stop a digital alarm from being displayed, set the alarm priority to Info Only.
Disabling (force off) the digital alarm off will disable all functions of the associated
digital input.
See the ION Reference, available from www.usa.siemens.com/pds, for more
information about the Setpoint and Relative Setpoint module, Digital Input module,
Sag/Swell module and Disturbance Analyzer modules.
