Chapter 3 Setting Up Measurements
Setting Up Alarms, Lists,
and Inspection Codes This section describes the way the Emonitor software loads alarms, lists, and
inspection codes into the Dynamix 2500 data collector.
For more information on alarms, lists, and inspection codes, see the
Emonitor software online help.
Alarms and the Data Collector
The Emonitor software and the Dynamix 2500 data collector support loading
alarms with the list of measurement definitions to the data collector.
You select the alarms you want to load with a measurement definition in the
Emonitor software by setting the Trigger column to Yes for the alarm. If you set
Trigger to Yes for two or more alarms for the same measurement definition, the
Emonitor software combines them to make a single alarm. If you select an alarm
that the data collector can handle, the Emonitor software loads that alarm into
the data collector when you load the list.
Selecting Alarms to Load to the Dynamic 2500 Data Collector
If you want to load an alarm to the data collector with a measurement definition,
you must set Trigger to Yes in the Alarm spreadsheet in the Emonitor software.
Alarms with the Dynamix 2500 Data Collector
The data collector supports some alarms and there are substitutes for some of the
unsupported alarms.
The data collector supports above, below, in window, and out of window
magnitude alarms for magnitude and numeric measurements. You cannot select a
magnitude out of window alarm in the Emonitor software.
You must create one by combining an above and a below alarm for the same
measurement definition. the Emonitor software creates an out of window alarm
when it builds the load file if both alarms are active.
The data collector does not support spectrum (narrowband) alarms for spectrum
measurements. You can still set up spectrum alarms with spectrum measurement
definitions. The Emonitor software tests the measurements against the alarms
after you unload the data.
For unsupported alarms, the Emonitor software tests the measurements against
the alarms when you unload the data collector. This means that the Emonitor
software always accurately indicates when a measurement is in alarm, regardless of
the number or complexity of the alarm(s). This is true for all active alarms,
regardless of their trigger status.
