Transforms (FFT) analyzer and data collector for predictive maintenance and
machinery vibration diagnostics. It is capable of measuring, processing, displaying
and storing a wide range of analysis functions. It can operate as a stand alone
instrument or you can download your measurements to your software application
for program analysis.
The combination of the Dynamix 2500 data collector with the Emonitor
software provides you with the tools for predictive maintenance using noise and
vibration analysis. The data collector can be used for a variety of other
applications also, such as balancing or bearing analysis.
A predictive maintenance program helps you decide when equipment needs to be
serviced or replaced. Part of a complete predictive maintenance program includes
vibration monitoring. The Emonitor software and the Dynamix 2500 data
collector let you to perform vibration analysis by collecting data samples.
Rockwell Automation Publication 1441-UM001B-EN-P - September 2012 13
Chapter 1 The Dynamix 2500 Data Collector
With the combination of predictive maintenance software and the Dynamix
2500 data collector, you can do the following:
• Create lists of measurement definitions for data collection.
• Load lists from the Emonitor software into the Dynamix 2500 data
collector.
• Collect magnitude, process, spectrum, time, and phase data.
• View selected alarms with the data.
The Dynamix 2500 data collector alerts you when a measurement exceeds
an alarm.
• Define and collect unscheduled measurements.
• Select inspection codes to store with a measurement, documenting the
condition of the machine.
• Unload the data from the Dynamix 2500 data collector directly into the
Emonitor database, along with any inspection codes and unscheduled
measurements.
In addition, the Emonitor software can optimize your data collection by
combining measurement definitions at a location. For example, the
software can combine magnitude and spectrum measurement definitions
so that the list appears to contain only a single measurement. This lets you
to collect all three measurements at one time, minimizing the time you
spend collecting data.

Using the Headphones
The Dynamix 2500 data collector lets you listen to the vibration signal as
measurements are being recorded. You need to have the optional part, the headset
adapter cable.
You can use either Connector A, or Connector B to listen to any data being
collected. The accelerometer would be connected to the opposite connector.
When collecting data, the headphone output is switched to listen to another
input channel (X, Y, Z, and R) by using the shift + left and right arrows.
The headphone output always cycles through X, Y, Z, and R, but only outputs
sound when set to a channel that is currently measuring data. The channels that
are collecting data are controlled by which connector (A, or B) that the
accelerometer is connected to.
See Dynamix 2500 Data Collector Optional Parts List on page 16

The Dynamix 2500 Data Collector Chapter 1
Battery Maintenance
These are recommendations to extend the life of the battery pack:
• If the data collector is not in use and/or not regularly charged, it should be
recharged at least every 25 days to prevent damage to the battery cells.
• If the battery pack is not installed recharge the battery pack every 12
months to prevent damage to the battery cells.
• Recalibrate the electronic state of charge meter around every 30th
recharge. This prevents the state of charge from showing an incorrect
battery charge percentage. To do this, fully discharge the battery pack and
then fully charge it without any interruptions, ideally with the data
collector off. It will take longer to charge the battery if the data collector is
on while charging.
• The battery capacity is reduced at temperature extremes, high and low.
Calibration
After a 12-month period, you may notice that a calibration reminder message
appears at the bottom of the Main Menu screen. This is just a reminder to get
your instrument calibrated. To hide the reminder message, select Calib (F4) and
the message will be hidden until the following month.
We recommend that you return the Dynamix 2500 data collector annually to
Allen-Bradley for calibration. For more information, see Rockwell Automation
Support on the back cover.

Value Description
Aggressive Default
Limits the auto-ranging to 20 mV level and sets the range limits from 1% to 70% of range.
When the input is under-range, the instrument recalculates the most appropriate setting and begin
data sampling. The range will not be adjusted a second time or checked prior to data collection.
Use Aggressive autoranging when faster data collection is desired. When using Aggressive
autoranging, set Auto Store to `Off,’ or set Auto Store Time to `2’ seconds when Auto Store is set to
`On.’
Conservative Allows auto-ranging to go as low as 2 mV and sets the range limits from 10% to 70% of range.
The instrument perform a series of checks prior to sampling data. This will result in longer data
collection times and potentially lengthy acquisition.
When the input is under-range, the instrument recalculates the most appropriate range setting and
sample data to make sure the range has been properly selected. In addition, the dynamic range will
be adjusted several times prior to data collection.
Use Conservative autoranging when large variations in signal amplitude are present for proper input
range selection but increases the settling time required.
Fixed No autoranging measurements are taken. Input range is set based on the transducer type and
sensitivity.
For example, an accelerometer, the input range will be 5 V for 100 mV/G sensitivity or 500 mV for 10
mV/G sensitivity.

• If Autoranging is set to Fixed or Aggressive, the software integration is used on all FFT measurements. This is to give
improved dynamic range and faster hardware settling times.
• If hardware integration is required, set Autoranging to `Conservative.’
• For all autoranging settings (including Fixed), the input range is automatically increased and the data retaken if clipping
occurs. This means that the final input range used will never be too low for the signal being measured.

Chapter 2 Configuring the Dynamic 2500 Data Collector
Value Description
Normal Sets the auto-ranging algorithm to only track signals above 120 rpm. Therefore, use this setting
when the machine speed is greater than 120 rpm.
The normal speed setting guarantees the waiting time be no longer than 0.5 seconds. It will
significantly improve auto-ranging times and therefore data collection times for any points that
have low filters (<2 Hz) selected.
Slow Sets the auto-ranging algorithm down to the Low Pass Filter setting. (If none, it will track down to
approximately 0.33 Hz or 20 CPM.) Therefore, use this setting when the machine speed is less than
120 rpm.
The slow speed setting enables low frequency auto-ranging to accommodate collection of low
frequency components. For slow speed equipment, this is necessary to be sure adequate sampling
and collection of the peak signal. The slow speed setting allows the Dynamix 2500 data collector to
auto-range on machines running as slow as 20 rpm. The auto-ranging algorithm makes an
assumption about the speed of the machine that is being monitored to determine how long to wait
for the peak signal value to be seen. With the slow speed setting, the wait-time is calculated as 1
/ f
hpf
where f
hpf
is the high-pass filter cutoff in Hz for the current point.
For example, if a 0.36 Hz filter is selected, the auto-ranging algorithm will wait for 1 / 0.36 = 2.78
seconds to make sure it has seen the peak signal value.

Automatic Samples the trigger signal before collecting the triggered measurement and sets an appropriate trigger
level automatically. When collecting data on a triggered point, a message displays on the screen while
the trigger level is being sampled.
The length of time for which the trigger is sampled during autotriggering is dependent on two factors:
• The high pass filter selected for the point.
• The lower the high pass filter cutoff, the longer the trigger will be sampled.
Mach. Speed
If the Mach. Speed is set to `Normal,’ the maximum trigger sampling time is about one second. If the
Mach. Speed is set to `Slow,’ the maximum trigger sampling time is about 10 seconds. The Normal
setting supports autotriggering on machines running at speeds down to ~120 rpm. The Slow setting
will support autotriggering on machines running at speeds down to ~6 rpm, depending on the width of
the trigger pulse.

Using Memory Cards
The Dynamix 2500 data collector can store program information and collect data
internally and on a memory card. The data collector accepts a standard SDHC
storage card up to 16 GB that is supported with a Microsoft Windows CE driver.
The storage card can be inserted when the instrument is powered on or off.
The Dynamix 2500 data collector is only certified for use with the Sandisk
Secure Digital (SD) card SDSDx-yyy.
Due to the limitations of the Windows CE operating system. The largest
single file size can be 2 GB.
Insert and Remove a Storage Card
You insert the memory card into the collector through the base cover at the
bottom of the instrument. The memory card can be inserted while the Dynamix
2500 data collector is powered on or off.
The SD storage card must be initialized/formatted before you can use it
in the data collector. The data collector does not initialize/format the
cards.

Setting Up Measurements
This chapter describes setting up the measurement definitions in the Emonitor
software, how alarms are handled, lists, and inspection codes.
Measurement definitions define how to collect and store measurements. You can
create several different types of measurement definitions at each location. The
Emonitor software can then take advantage of the abilities of your data collector
by combining some of the measurement definitions when you load them into the
data collector. By combining measurements, the software can shorten the data
collection time.

IMPORTANT
When using the Dynamix
2500 data collector, select
the Enpac 2500 (EP25)
driver.
Measurement Definition Options
From the Tools menu, choose Set Active Collectors to determine the definitions
for measuring in the Emonitor software.
Figure 11 - Set Active Collectors
If no data collectors are active, the selections that appear in the
Measurement Definition pane are the ones available to all data
collectors:
• If only the Dynamix 2500 data collector is active, then only the
valid choices for the unit appear in the lists.
• If the data collector and other data collectors are active at the
same time, you see the selections that are common to all data
collectors that are active.
Therefore, you may not see all the selections available for the
Dynamix 2500 data collector.
In some cases, both the Emonitor software and the Dynamix 2500 data collector
support only certain options. In other cases, the Emonitor software can support
an option that the Dynamix 2500 data collector cannot support.
For example, the Emonitor software can apply a software high pass filter to the
data after it unloads the data from the Dynamix 2500 data collector. This lets you
use a filter that is not available in the data collector.

the selections available for the Dynamix 2500 data collector.
Measurement Filters
The Emonitor software and the Dynamix 2500 data collector each support
certain measurement filters. Some of the filters are supported in both. You can
define custom band filters (high pass, low pass, band pass) by creating a new band
filter using the Band Filter function. You can choose to use a filter in the Dynamix
2500 data collector by selecting the Analog or RSS (digital) option when you
define a filter.

1. From the Setup menu, choose Band Filters.
2. Choose a Band Filter and click New.
3. Type a name and click OK.
Filters in the Emonitor software are referred to as software filters. Filters in data
collectors are referred to as hardware filters.
Hardware filters alter the signal in the data collector. The Emonitor software
filters alter the signal (data representing the signal) after you unload the data into
the software.
In general, if the filter you want to use is available in both the software and in the
data collector, it is to your advantage to use the hardware filter in the data
collector.
Advantage of Hardware Filters
They can remove low frequency, high amplitude signal components that would
dominate the dynamic range in the data collector. This results in improved
amplitude resolution of the remaining signal range.
When collecting 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.
These are two other ways you can reduce ranging time:
• Only use filters that are built into the data collector.
• Change the Autoranging in the Instrument Configuration menu to
either Fixed or Aggressive.
See Instrument Configuration Parameters on page 59
for more information
about filters.
Advantage of Software Filters
If there is no corresponding filter in the data collector, or you choose not to use it,
the Emonitor software can apply a digital filter after you unload the data from the
data collector.
gSE Filters
Use a gSE filter to detect bearing and other component defects. The gSE filters
provide a demodulated measurement similar to the ‘envelope’ measurements in
other instruments. You can use gSE filters with magnitude and spectrum
measurement definitions.
These six gSE filters are available in the Dynamix 2500 data collector. If you
select the Envelope filter, the Emonitor software automatically picks the 5 kHz
gSE filter.

ESP Filters
Use an Envelope Spectrum Processing (ESP) filter to detect bearing and other
component defects. The ESP filters apply a band pass filter, envelope the time
domain signal, and then perform a frequency analysis on the result. ESP filters are
built into the Dynamix 2500 data collector, and you cannot change them in the
Emonitor software. You can use ESP filters with the magnitude and spectrum
measurement definitions.
The following ESP filters are available with the Emonitor software and the
Dynamix 2500 data collector:
• 0.6…1.25 kHz
• 1.25…2.5 kHz
• 2.5…5 kHz
• 5…10 kHz
• 10…20 kHz
In Emonitor software, on the Data Collector dialog box, the
Enpac Emulation parameter must be set to No.
See Data Collector Advanced Settings Parameters on page 112
for Settings descriptions.
High Pass Filters
Use a high pass filter to remove high vibration, low frequency signal components
that would dominate the signal. For example, structural vibration or signal
components generated by an integrator.
The high pass filter excludes all frequencies below a defined frequency. It allows,
or passes, frequencies above the defined frequency. You define these and other
band filters using the Setup > Band Filter function in the data collector. You can
use a high pass filter with the magnitude and spectrum measurement definitions.
If you select Analog as the data collector filter type, when you define a high pass
filter, the data collector uses one of the following filters determined by the
following formula.

Order (Magnitude) Filters
Use order filters to define the bands around orders for magnitude and
magnitude+phase measurements. You define these filters using Setup > Band
Filter function in the data collector. You can use order filters with the magnitude
and spectrum measurement definitions.
You can define and use order filters for the first through the eighth orders with
the Dynamix 2500 data collector. If you specify the Maximum frequency in
Orders filters, select Analog and Order normalize when you define the orders
filters, then the data collector calculates the orders from an external trigger.
The Dynamix 2500 data collector then uses its own filters to calculate the
magnitude and phase for the first through the eighth orders. The Emonitor
software calculates the magnitude values (without phase) for additional orders
after you unload the data.
If you select None instead of Analog, the Emonitor software also calculates
magnitude values after you unload the data.
If you want phase, remember to specify the Maximum
frequency (in Collection Specification dialog box) in Orders,
select Analog in the Band Filter Specification dialog box and
Order normalize in the Collection Specification dialog box. The

Envelope Typically this filter maps to one of the gSE filters in the data collector and is
available for magnitude and spectrum acceleration measurements. In the
Dynamix 2500 data collector, it maps to the 5 kHz gSE filter.
SmartHP (Smart High Pass) Typically this filter maps to a specific high pass filter in the

measurements. In the Dynamix 2500 data collector, it maps to the filters
shown in the table below, depending on the results of comparing the filter
choice to the formula below.

RSS Overall
The Dynamix 2500 data collector lets you to take a digital overall measurement,
instead of analog. This set up makes measurement collection faster. Be aware that
this Root Sum Squares (RSS) overall value is not as complete because it does not
include the power in the signal from below the first spectral bin or above the
highest spectral bin. The RSS overall values may not trend well with analog
overall measurements.
To use the RSS filter, you must create a Band Filter in the Emonitor software.
1. Select Setup > Band Filter and click New.
2. Choose RSS (digital) as the filter type.

non-integrated measurements will always cause the Dynamix
2500 data collector to go into a long autorange mode. Only use
these filter settings when very low frequency data is required.
Measurement Units
The Emonitor software and the Dynamix 2500 data collector support many
different measurement units. The measurement units that appear in the data
collector are text that depend on the following definitions:
• Type of measurement definition
• Units for the measurement definition
• Transducer specification used in the collection specification for the
measurement definition
The data collector collects data for english units, metric units, or decibels. It uses
the units that you select in the Emonitor software. You can select units from a
single system, for example, English g’s, in/sec, or you can mix units from different

Setting Up Collection Specifications
Measurement definitions are controlled in part by the collection specification
(Setup > Collection). You select the collection specification when you set up the
measurement definition. You can create new collection specifications based on
your specific measurement by choosing Setup > Collection.
Figure 13 - Collection Specification Dialog Box
The transducer specification used in the collection specification includes both
the base unit and the calibration value.
Edit the Measurement Definitions
The Emonitor software does not allow you to change some of the information for
a measurement definition after you collect data for that measurement definition.
This prevents you from collecting and then comparing data with different
measurement definition selections. You cannot edit the Data Type or Units
columns in the Measurement Definition dialog box after you collect data You
can, however, change the Collection, Filter, and the Storage columns for a
measurement definition after collecting data.
Changing the collection specification can make it difficult to
compare data after the change with data before the change.
The figures in a typical measurement setup in the following sections refer to
making selections in these dialog boxes. For example, a table for STD (HZ) 2000
collection specification would look like this.

1. Convert CPM to Hz.
2. Find the total collection time.
Number and Type of Averages
The number and type of averages are part of the collection specification (Setup >
Collection). See Collection Specification Dialog Box on page 75
Select the collection specification when you set up the measurement definition.
The Emonitor software and the Dynamix 2500 data collector support the
following number and types of averages for data collection.
Averages Description
Linear Up to 4096 averages.
Time Synchronous Up to 255 averages, and requires a trigger.
Exponential Up to 99 averages. Uses exponential weighting. Use for measurements on a
continuous signal that may be slowly varying. Also use to obtain a uniform
statistical error over all frequencies.
Peak Hold Up to 99 averages. Holds the highest measured value in each bin (line).
Averaging is useful for reducing random errors. Random errors include
background vibration due to some source other than the machine being
measured. If you collect more averages, you have fewer random errors. However,
collecting more averages requires more time.
.
Overlap processing (Percent overlap) speeds up the averaging process. The
overlap amount determines how much of the time samples are overlapped for
successive averages. The greater the overlap, the faster the sample can be collected.
The disadvantage is that the greater the overlap, the less new data there is, and the
greater the influence of random errors.
80 Rockwell Automation Publication 1441-UM001B-EN-P - September 2012
Setting Up Measurements Chapter 3
Order Normalization for Orders Track Spectrum
There are two requirements for implementing Orders Track measurements. The
Fmax value must fall within the range of 10 to 5000 Hz, and the machine speed
may not vary by more than 10% during the measurement collection.
For example, if you set up a machine that runs at 3500 rpm for an Fmax of 100
Orders, the measurement will not work because the required Fmax is 15,000 Hz.
To Set Up Orders Track FFT Collection
The Dynamix 2500 data collector supports the specification and collection of a
spectrum with an Fmax defined in terms of number of orders for a varying
machine speed. For Orders Track data collection, you are required to use a trigger
to continually determine machine speed.
With orders tracking, the sampling rate is not fixed during the collection period.
Instead, the time spacing between the samples may be constantly varying so that a
fixed number of samples per shaft revolution is collected. The x-axis of the time
waveform is no longer measured in seconds, but instead it is measured in degrees
or shaft position. From this, the corresponding spectral information is no longer
measured in Hz or CPM, but instead it is measured in orders. Orders tracking
removes all non-synchronous frequencies from the spectrum.
Follow these steps to set up route points using the Orders Track collection.
1. Create a collection specification in the Emonitor software that uses Orders
for the maximum frequency (Fmax).
Rockwell Automation Publication 1441-UM001B-EN-P - September 2012 81
Chapter 3 Setting Up Measurements
Orders Track
2. Also, check the Order Normalization checkbox to signify Orders Track to
the Dynamix 2500 data collector.
3. Create a Spectrum measurement definition that uses the Orders Based
collection specification.
4. Tag that measurement and load it to the Dynamix 2500 data collector with
a list.
For Orders Track data collection, you are required to use a trigger to continually
determine machine speed.
Orders tracking analysis can be used effectively to diagnose the vibrations of
variable speed machines. The orders tracking yields data in the revolution
domain, not the time domain. In an orders spectrum, signals that are periodic in
the revolution domain appear as peaks and orders or harmonic components
remain fixed in their position through speed changes. This is a clear advantage
when comparing the characteristics of variable speed machines over a period of
time.
Using Frequency Items for the Diagnostic Frequency Cursor
Using the Dynamix 2500 data collector, you set up frequency items in the
Emonitor software and download them to the Dynamix 2500 data collector.
Then, you can review the data using the Diagnostic Frequencies cursor. This
feature lets you to diagnose the peaks you see in the Dynamix 2500 data collector
using the frequency items from the host software.
82 Rockwell Automation Publication 1441-UM001B-EN-P - September 2012
Setting Up Measurements Chapter 3
To load the Diagnostic Frequency labels, you must check the Load Frequency
Labels checkbox in the Load Options dialog box.
Setting Up Speed References
The Dynamix 2500 data collector can determine the speed using speed references
in the Emonitor software. The speed reference value is used by the frequency
items to calculate the Fmax of the dependent measurements.
To set up speed references in the Emonitor software, double-click in the rpm
column in the Location pane.
The Machine Speed Setup dialog box appears.
You can choose a frequency reference item as your machine speed reference. This
allows for machine speeds to be stored and retrieved dynamically. The Dynamix
2500 data collector supports two types of frequency types: speed reference and
linear rotational.
If you want to use a collected measurement from the Dynamix 2500 data
collector to set the machine speed, you have two options:
• Use a manual entry process measurement to enter machine speed by
reading it from any instrument in your plant. The measurement can then
be referenced for the machine speed, and would be updated every time you
unload that measurement.
Rockwell Automation Publication 1441-UM001B-EN-P - September 2012 83
Chapter 3 Setting Up Measurements
TIP
Current spectrum measurement and Extract from
current spectrum measurement are not supported in
the Dynamix 2500 data collector 2500.
• Use a measurement with Order normalization checked in the collection
specification. The machine speed from an internal or external tachometer
will be used for the machine speed. If the Order normalization checkbox is
not checked, the Dynamix 2500 data collector will use a fixed Fmax value
and will not calculate the Fmax based on the current speed of the machine.
The Orders normalization checkbox does not produce
Orders Tracking measurements when used with speed
references.
The Emonitor software orders all the measurements in the route so that the
dependent machine speed measurement is collected first. This way, the route is
set up for the most accurate machine speed entry, and the measurements refer to
the correct machine speed. The band alarms and frequency labels adjust to
changes in the machine’s speed.
To set up the Speed Reference Frequency for the Dynamix 2500 data collector,
double-click in the Definition column in the Speed Reference row in the
Frequency Item pane. The Speed Reference Frequency dialog box appears.
There are three ways to obtain a speed references:
• You can enter a constant for the speed.
• You can use the value in the Machine Speed column for a location on an
item in the Hierarchy Tree.
• You can use the value from a process measurement as the speed.
Press F1 to find out more information about each option in the Speed Reference
Frequency dialog box.
84 Rockwell Automation Publication 1441-UM001B-EN-P - September 2012
Setting Up Measurements Chapter 3
You can set up the Linear to Rotational Frequency by double-clicking the
Definition column in the Linear to Rotational row in the Frequency Item pane.
This dialog box lets you to set up a rotational frequency item based on a linear
speed.
Unsupported Measurement Selections
Each data collector supports only certain selections in the drop down lists in the
Measurement Definition pane. the Emonitor software automatically displays the
correct selections when you select one or more active collectors. You select the
active collector or collectors by choosing Tools > Set Active Collectors in the
Emonitor software. If you do not select the Dynamix 2500 data collector as the
active collector, it can affect the selections in one of two ways:
• If you do not select any collectors, the Emonitor software displays all
possible selections, not just those for the Dynamix 2500 data collector.
• If you select two or more different collectors, the Emonitor software
displays only the selections that are available for both collectors.
As an example, there are certain filters available in the Dynamix 2500 data
collector. Then there are three possible cases:
• You select the Dynamix 2500 data collector as the only active collector. the
Emonitor software displays the correct filters in the measurement filter
column of the Measurement Definition pane.
• You do not select any active collectors. the Emonitor software displays
many more filters than are available for the Dynamix 2500 data collector.
• You select two or more active collectors. the Emonitor software may
display only some, or none, of the filters that are available for the Dynamix
2500 data collector.
For more information on setting the active collectors, see the Emonitor software
online help.

Chapter 3 Setting Up Measurements
Setting Up Measurement Definitions
The Emonitor and the Dynamic 2500 data collector can collect and store a wide
range of measurements. A few questions can arise when determining how the
Emonitor software works with the Dynamix 2500 data collector for each
different type of measurement definition:
• How does the Emonitor software handle measurement units and alarms
available in the Emonitor software but not supported in the Dynamix
2500 data collector?
• How many orders of magnitude and phase can the Dynamix 2500 data
collector collect?
• How does the Dynamix 2500 data collector support collecting a spectrum
when a magnitude measurement is in alarm?
The Emonitor software combines measurement definitions when it creates a load
file from a list of measurement definitions. For example, the Emonitor software
can combine the measurement definitions at a location so that the data collector
collects all the measurements at one time. This makes data collection faster and
more efficient because you do not have to start each measurement individually.
The Emonitor software and the Dynamix 2500 data collector are designed to
make collecting data as quick and efficient as possible. To shorten data collection
time, the Emonitor software combines two or more measurement definitions at a
location into a single measurement. This lets you collect two or more
measurements by pressing a single key on the Dynamix 2500 data collector.
For more general information on setting up measurement definitions, see the
Emonitor software online help.
Magnitude Measurement Definitions
The Emonitor software and the Dynamix 2500 data collector support magnitude
measurement definitions. This topic lists the unique characteristics of the
Dynamix 2500 data collector that you may need to know when setting up and
collecting magnitude data.
Measurement Units Not Supported in the Dynamic 2500 Data Collector
• Magnitude measurement definitions with unit not supported by the
Dynamix 2500 data collector map to units of USER (eus) in the data
collector. This results in a process (DC) voltage measurement.
• For a list of supported measurement units, see Measurement Units on
page 74.
When you display a measurement definition in the data collector with an
unsupported unit, it chooses the USER (eus) units. You can still collect and store
data using unsupported units.
86 Rockwell Automation Publication 1441-UM001B-EN-P - September 2012
Setting Up Measurements Chapter 3
Magnitude Alarms in the Dynamic 2500 Data Collector
• The Dynamix 2500 data collector supports above, below, in window, and
out of window magnitude alarms.
• You must set Trigger to ‘Yes’ for any magnitude alarms you want to appear
in the Dynamix 2500 data collector during data collection.
• For more on how the Emonitor software combines alarms before sending
them to the Dynamix 2500 data collector, see Alarms and the Data
Collector on page 104.
Collecting Magnitude Measurements in Multiple Frequency Bands
You can set up multiple measurement definitions at a location to collect
magnitude values for individual frequency bands. Use band filters to define the
different frequency bands in the measurement definitions.
Make sure you select None in the Band Filter dialog box. This forces the
Dynamix 2500 data collector to collect a spectrum measurement. After you
unload the measurement, the Emonitor software calculates the magnitude values
in the bands from the spectrum.
If your measurements include both magnitude and phase, the unit can collect up
to eight orders. If your measurements include magnitude only, the unit can
collect up to 200 orders.
Proximity Probe Measurements
Proximity probes measure the movement of a shaft within a bearing. You usually
make two types of proximity probe measurements with magnitude measurement
definitions.
The dynamic or AC component indicates the changing (dynamic) distance
between the probe and bearing shaft. The static or DC component indicates the
average distance between the probe and the shaft. This is also referred to as the
DC gap.
Follow these steps to setup a Dynamic (AC) Component.
1. Set up a displacement transducer in the Transducer Calibration dialog box
with Input type set to AC Coupled and Units set mils or um.
Make sure you enter the Calibration value that converts the voltage to a
displacement.
2. Set up a Collection Specification with Transducer set to the AC
displacement and Signal detection set to Peak-peak.
Rockwell Automation Publication 1441-UM001B-EN-P - September 2012 87
Chapter 3 Setting Up Measurements
3. Finish setting up the dynamic proximity probe measurement by setting
Data Type to Magnitude and Units to mils or um.
You can use a Filter if desired.
Follow these steps to setup a Static (DC) component or gap.
1. Set up a displacement transducer in the Transducer Calibration dialog box
with Input type set to DC Coupled and Units set to mils or um.
Make sure you enter the Calibration value that converts the voltage to a
displacement. If you are using the DC Input Module to remove the AC
component and attenuate the signal be a factor of 2.5, then you must
divide your transducer’s calibration by 2.5.
2. Set up a Collection Specification with Transducer set to the DC
displacement and Signal detection set to RMS.
3. Finish setting up the dynamic proximity probe measurement by setting
Data Type to Magnitude and Units to mils or um.
You must set the Filter to None because any type of high pass filtering
removes the DC component.

• The data collector can collect phase only at the first through eighth
orders.
2500 data collector automatically uses its internal order filters if you
are collecting phase.
If you are collecting only magnitude values and you do not select this
option, the data collector collects a spectrum and the Emonitor
software calculates the magnitudes after unloading.
When collecting magnitude and phase at orders, the data collector
always collects a spectrum measurement, and then calculates the
magnitude and phase values from the spectrum.

degree.
This can be from the internal laser tachometer or from an external
trigger source such as a key phasor.
To Set Up Multiple Measurement Definitions for Magnitude and Phase
You create only one measurement definition for magnitude and phase at each
order. The Also collect phase data checkbox in the Collection Specification
dialog box determines whether you also want to collect phase as well as
magnitude data.
follow these instructions to set up multiple measurement definitions for
magnitude and phase.
1. Create a new measurement definition by selecting Magnitude in the Data
Type column in the Measurement Definition pane.
2. Select the units for the measurement definition, using a dynamic unit such
as g’s, m/s2, ips, mm/s, mils, um, or V.
3. Select the measurement filter.
4. Collect the magnitude and phase at an order, select a band filter centered
on the order.
For example, select (create if necessary) a first order band filter with a Low
cutoff of 0.8 Orders, and a High cutoff of 1.2 Orders.
See Measurement Filters on page 67
for details and the examples on the
following pages.
It is very important that order band filters be centered on the
order. For example, 0.7…1.3 orders, 0.8…1.2 orders, 0.9…1.1
orders, and so forth. If you do not center the band filters,
magnitude and phase readings may not be accurate.
5. Select the collection specification.
90 Rockwell Automation Publication 1441-UM001B-EN-P - September 2012
Setting Up Measurements Chapter 3
You must check the Also collect phase data checkbox in the Collection
Specification dialog box so the data collector collects phase at orders.
6. Select the storage specification.
The first measurement definition is now complete.
7. If you want to create more than one measurement, copy the measurement
definition by selecting the correct row and choosing Edit > Copy.
8. Move down to the next empty row in the measurement definition
spreadsheet, and choose Edit > Paste to paste the copied measurement
definition.
9. Edit the new measurement definition by changing the measurement filter.
10. Select a band filter centered on the next order.
11. Repeat steps 6 and 7 to create measurement definitions for the desired
orders.
You can then include these measurement definitions in a list and load it to
the data collector. Remember that you must have a trigger signal to collect
magnitude and phase at an order.

Numeric (Process) Measurement Definitions
The Emonitor software and the Dynamix 2500 data collector support numeric
measurement definitions. This topic lists the unique characteristics of the
Dynamix 2500 data collector that you may need to know when setting up and
collecting numeric data.
Measurements Units Not Supported in the Dynamic 2500 Data Collector
• You can make a numeric measurement definition for any available
measurement unit by setting Data Type to ‘Numeric.’
• Numeric measurement definitions with Input type set to ‘DC Coupled’
with units not supported by the Dynamix 2500 data collector map to units
of USER (eus). The input type is part of the transducer specification that
you select for the collection specification. This results in a process (DC)
voltage measurement in the Dynamix 2500 data collector.
• For a list of support measurement units, see Measurement Units on
page 74.
Full Scale Values for Numeric Measurements in the Dynamix 2500 data
collector
• The full scale value in the Dynamix 2500 data collector for a numeric
measurement is defined as ten times the value of the alarm or the baseline
measurement.
• If no alarm or baseline measurement exists for the measurement in the data
collector, the Dynamix 2500 data collector assumes a full scale value of
10,000.
92 Rockwell Automation Publication 1441-UM001B-EN-P - September 2012
Setting Up Measurements Chapter 3
• A full scale value of 10,000 can be a problematic if you want to enter a very
large or very small value for the numeric measurement. For example, you
can not enter a value greater than the full scale value. If you enter a value
that is very small compared to the full scale, the Dynamix 2500 data
collector may round the value off. If you enter 0.01 with a full scale value of
10,000, the Dynamix 2500 data collector stores it as a 0 (zero).
Temperature Measurements
You set up a temperature measurement definition by setting Data Type to
Numeric and Units to rpm, CPM, or deg. C.
Follow these steps to set up temperature measurements.
1. Set up the temperature transducer in the Transducer Calibration dialog
box with Input type set to DC Coupled and Units set to deg. F or deg. C.
Make sure you enter the Calibration value that converts the voltage to a
temperature.
2. Set up the collection specification to include a Signal detection of RMS.
Machine Speed (rpm) Measurements
You set up a tachometer measurement definition by setting Data Type to
Numeric and Units to rpm, CPM, or Hz.
Follow these steps to set up machine speed measurements.
1. Go to the Transducer Calibration screen.
2. Set the Input type to ICP Accel for either the internal laser tachometer or
an external TTL device, for example, entach laser sensor, an optical trigger,
or a strobe light with TTL output.
3. Set the Input type to AC Coupled or DC Coupled if your speed sensor has
an AC or DC voltage signal proportional to speed.
4. Set Units to rpm, CPM, or Hz.
Make sure you enter the Calibration value that converts the voltage to
speed.
5. Set up a Collection Specification with Transducer set to the tachometer
transducer you set up above, Window set to Rectangular, and Signal
detection set to None.
Do not fill in any fields in the Resolution area or the Averaging area of the
dialog box.
Rockwell Automation Publication 1441-UM001B-EN-P - September 2012 93
Chapter 3 Setting Up Measurements
6. Connect the speed sensor to the trigger connector on the Dynamix 2500
data collector when collecting data.
Magnitude Alarms in the Dynamic 2500 Data Collector
You can use magnitude alarms with numeric measurements:
• The Dynamix 2500 data collector supports above, below, in window, and
out of window magnitude alarms with numeric measurements.
• You must set Trigger to Yes for any alarms you want to appear in the
Dynamix 2500 data collector during data collection.
For more on how the Emonitor software combines alarms before sending
them to the Dynamix 2500 data collector, see Alarms and the Data
Collector on page 104.

Spectrum Measurement Definitions
The Emonitor software and the Dynamix 2500 data collector support spectrum
measurement definitions. There are unique characteristics of the Dynamix 2500
data collector that you may need to know when setting up and collecting
spectrum data:
• The Dynamix cannot collect phase with a spectrum measurement
definition.
Do not check the Also collect phase data checkbox in the
Collection Specification dialog box.
• You can choose to have the Dynamix 2500 data collector collect a
spectrum only if a magnitude measurement at the same location is in
alarm.
Set the Collect and store condition in the Edit Storage Specification dialog
box to On Magnitude Alarm for the storage specification for the spectrum
measurement definition.
Time Synchronous Averaging in the Dynamic 2500 Data Collector
Time synchronous averaging cancels out the effects of signals not related to the
synchronizing trigger. Time synchronous mechanical effects include imbalance,
misalignment, eccentricity of bent shafts, blade passing, and gear meshing:
• Time synchronous averaging requires the internal laser tachometer or
external trigger.
• Set up a Collection Specification with the averaging Type set to Time
Synchronous and enter the Number of averages.
• Use a large number of averages (such as 20 or 30) to get the desired
reduction in non-synchronous effects.
For more on supported averaging in the Dynamix 2500 data collector data
collector, see Number and Type of Averages on page 80
.
Order Normalized Spectra in the Dynamic 2500 Data Collector
Order normalized spectrum measurements have a frequency axis based on
multiples of the running speed (orders). This quickly identifies the frequency
relationship between each measured vibration amplitude and the running speed
of the machine. It is particularly useful on variable speed machinery.
An order normalized spectrum measurement requires a trigger input to the
Dynamix 2500 data collector.
Rockwell Automation Publication 1441-UM001B-EN-P - September 2012 95
Chapter 3 Setting Up Measurements
TIP
To up a Collection Specification with Window set to Hanning, select the
Maximum frequency in Orders, and make sure to select the Order normalization
option.
The Averaging can be either linear or time synchronous, but should
include at least four averages.
The Dynamix 2500 data collector may collect more orders than required. For
example, if you set the Maximum frequency to 10 Orders, the Dynamix 2500
data collector may collect more than ten orders. The Dynamix 2500 data
collector always collects at least the number of orders you request in the
Collection Specification.
The Dynamix 2500 data collector displays an order normalized spectrum:
• If the Collection Specification dialog box has Also collect phase data
checked, and if the Maximum frequency is eight orders or less, the table on
the instrument’s screen shows the magnitude and phase values at each
order.
• If the Collection Specification dialog box does not have the Also collect
phase data checkbox checked, or if the Maximum frequency is more than
eight orders, the table on the data collector shows magnitude values only.
The instrument displays a maximum of eight orders in the table.
• If the table has eight orders or less, the arrow keys move the spectrum
cursor.
• If the table has more than eight orders, the arrow keys scroll the table
values.
Proximity Probe Measurements
Proximity probes measure the position and motion of a shaft within a bearing.
You can use a spectrum measurement definition to measure the dynamic or AC
component of a proximity probe measurement. This indicates the motion of the
shaft within the bearing at each frequency.
Follow these steps to set up a proximity probe.
1. Set up a displacement transducer in the Transducer Calibration dialog box
with Input type set to AC Coupled and Units set to mils or um.
Make sure you enter the Calibration value that converts the voltage to a
displacement.
2. Set up the Collection Specification to include the displacement
Transducer, and set the Signal detection to Peak-Peak.
96 Rockwell Automation Publication 1441-UM001B-EN-P - September 2012
Setting Up Measurements Chapter 3
IMPORTANT
You also need to select the window, frequency range, and averaging
options.
3. Finish setting up the dynamic proximity probe measurement by setting
Data Type to Magnitude and Units to mils or um.
You can use a Filter if desired, but make sure it does not interfere with the
frequency of interest.
Spectrum Alarms in the Dynamic 2500 Data Collector
The Dynamix 2500 data collector supports band alarms with up to ten bands.
You can have the data collector collect a spectrum measurement if a magnitude
alarm is in alarm.
1. Set the Collect and store condition in the Edit Storage Specification dialog
box to On Magnitude Alarm for the storage specification for the spectrum
measurement definition.
2. You must set Trigger to Yes for any alarms you want to appear in the
Dynamix 2500 data collector during data collection.
If you set Trigger to Yes for two or more alarms for the same measurement
definition, the Emonitor software combines the alarms before sending the
combined alarm to the Dynamix 2500 data collector.
For more on how the Emonitor software combines alarms before sending them to
the Dynamix 2500 data collector, see Alarms and the Data Collector on
page 104.
The Dynamix does not support spectrum alarms. You can still set up the
alarms for the spectrum measurement definitions. the Emonitor software
tests the data against the alarms after you unload the data.
Typical Spectrum Measurement Definitions

Time Waveform Measurement Definitions
The Emonitor software and the Dynamic 2500 data collector support time
waveform measurement definitions. This topic lists the unique characteristics of
the Dynamix that you may need to know when setting up and collecting time
waveform data.
The Dynamix 2500 data collector cannot collect phase with time waveform
measurement definitions. You can choose to have the instrument collect a time
waveform only if a magnitude measurement at the same location is in alarm.
Set the Collect and store condition in the Edit Storage Specification
dialog box to On Magnitude Alarm for the storage specification for the
time waveform measurement definition.
The Dynamic 2500 data collector supports integrated time waveform
measurements (single integration). This means you can collect a time waveform
with velocity units using an accelerometer or displacement units using a velocity
transducer.
The length of the time waveform depends on the maximum frequency you select
in the collection specification. You can calculate the number of time samples from
the number of spectral lines (Collection Specification dialog box) using this
formula.
You can calculate the total time required to collect a time waveform measurement
from the Number of lines value and the Maximum frequency value in the
Collection Specification dialog box (Setup > Collection Specification).

If your Maximum frequency is specified in CPM, convert CPM to Hertz using
this formula.
Next, find the total collection time for the time waveform measurement using
this formula.
If you had a Maximum frequency value of 7200 CPM and a Number of lines
value of 400, you would:
1. Convert CPM to Hz.
2. Find the total collection time.

Time synchronous averaging cancels out the effects of signals not related to the
synchronizing trigger. Time synchronous mechanical effects include imbalance,
misalignment, eccentricity of bent shafts, blade passing, and gear meshing.
Time synchronous averaging requires the internal laser tachometer or an external
trigger input to the data collector.

Voltage Measurement Definitions
The Emonitor software and the Dynamic 2500 data collector support
measurement definitions with units of volts (AC or DC). You can collect several
different types of voltage measurements. This topic shows the typical
measurement definition setup for three voltage measurements.
Voltage is similar to other units in that you can collect magnitude, numeric,
spectrum, and time waveform voltage measurements.
