Frequently Asked Questions and Answers 121
Why are the alarms in the Enpac Ex not what I selected?
You select the alarms you want to load with a measurement definition in Emonitor
by setting the Trigger column to "Yes" for the alarm. If you select an alarm that the
data collector can handle, Emonitor loads that alarm into the data collector when
you load the list.
Why aren’t inspection codes available for a list?
You must load the inspection codes into the
Enpac Ex
before they are available for
a list. Emonitor loads inspection codes only when you load a list. To load the
inspection codes, you must select Load inspection codes in the Load Options
dialog box in Emonitor. You can have a different set of inspection codes loaded
with each list. For more information on inspection codes,
see Loading Inspection
Codes on page 69.
How can I reduce the ranging time required during collection?
Long ranging times are associated with trying to collect low frequency
vibration data. Applying an overall filter helps reduce long ranging times. In
particular, overall filters with the highest low frequency cutoff point decrease
ranging time the most. Try to set your maximum frequency and lines of
resolution such that the formula results in the highest value that would be
practical in your application.
Another technique that can reduce ranging time is to only use filters that are
built into the data collector.
Unloading Data from the
Enpac Ex How do I unload data from more than one list?
The Enpac Ex allows you to unload more that one list at a time into the
Emonitor database. Simply select the desired lists before clicking the Unload
button. For more information, see Selecting the List(s) on page 71.
