The combination of the Enpac 2500 data collector with Emonitor software
provides a complete package for predictive maintenance by using noise and
vibration analysis. The Enpac can also be used for a variety of other applications,
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. Emonitor and the Enpac 2500 allow you to perform
vibration analysis by collecting data samples.

With the combination of predictive maintenance software and the Enpac 2500,
you can:

• Create lists of measurement definitions for data collection.

• Load lists from Emonitor into the Enpac 2500.

• Collect magnitude, process, spectrum, time, and phase data.

• View selected alarms with the data. The Enpac 2500 alerts you when a

measurement exceeds an alarm.

• Select inspection codes to store with a measurement, documenting the

condition of the machine.

• Unload the data from the Enpac 2500 directly into the Emonitor database,

along with any inspection codes and unscheduled measurements.

Rockwell Automation Publication GMSI10-UM002D-EN-E - August 2012 19

Chapter 1 The Enpac 2500 Data Collector

IMPORTANT

In addition, Emonitor can optimize your data collection by combining
measurement definitions at a location. For example, Emonitor could combine
two magnitude and one spectrum measurement definitions so that the list
appears to contain only a single measurement. This allows you to collect all three
measurements at one time, minimizing the time you spend collecting data.

The Enpac 2500 is a two-channel, real-time Fast Fourier Transformer (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.

Safety Information

Be aware of these safety precautions.

Avoid Water

The Enpac 2500 data collector is splash and dust resistant. However, avoid
direct contact with water, wet surfaces, or condensing humidity. Keep this
instrument away from wet locations, for example, laundry, wet basements,
swimming pools.

If the data collector subject to these conditions, adverse operation may result.
Before you use it, let the instrument dry thoroughly before operating.

ATT EN TI ON : To avoid damage or injury, place the Enpac 2500 data collector on
a solid stable surface when not in use and do not place any heavy objects on it.
Use only the accessories recommended by Rockwell Automation. Keep liquids
and foreign objects away from the instrument, and never operate it if any liquid
or foreign object has entered it.

Optical Ports

ATTENTION: When the laser on the data collector is active, viewing the laser

beam can expose your eyes beyond the maximum permissible exposure
recommendations and cause harm.

Laser Radiation Ports

ATTENTION: Class 1 laser product. Laser radiation is present when the system is

open and interlocks bypassed. Only trained and qualified personnel should be
allowed to install, replace, or service the instrument.

Chapter 1 The Enpac 2500 Data Collector

Value Description

On Default

The display is updated only when the data collector has collected and averaged all the data.
For example, if the number of averages is set to 20, then data is displayed only when 20 blocks have been collected and

averaged. There is no progress indication during data collection, only a `Collecting data... message.
This speeds up the data collection of the spect ra by using the percent overlap specified in Emonitor. The interim averages

are not displayed.

Off The display is updated as often as possible while the data collector is collecting and averaging the data. For example, if

the number of averages is set to 20, then data might be displayed for averages 1, 6, 12, 18, and 20. The averages that are
displayed depends on the Fmax and number of lines selected. If each block is acquired very quickly then only the first
and last updates may be seen. Data can be stored at any time once the spectrum has been displayed.

Important: The Off option applies only to spectral averaging, not time synchronous averaging. This means it has no
effect on Phase points or other time synchronous averaged measurements.

Value Description

On The instrument automatically accepts both the overall and signature measurements and proceeds to the next point in

the list.
The overall measurement is accepted based on an algorithm. The algorithm is based on a percent fluctuation over a

period of time (seconds).
If the overall stays with the % specified by Percent for the number of seconds specified with Time, the overall magnitude

is accepted.
You must press Enter to accept the overall measurement, and then press Enter again to accept the signature

measurement.

Off Default

Value Description

On The instrument automatically moves forward to the next point in the list after

collecting data for the current point. No spectrum is displayed.

Off Default

Value Description

Single shot Measures a single average for the signature and then stops.
Continuous Default

Continuously measures the signature until you press Enter to stop the averaging. This will pause the acquisition. Press
the Continue function to restart the acquisition. Press Enter a second time to store the data.

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 Aggres sive 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.

Transducer Input Range (EUs)

Accelerometer 50 g
Veloc imeter 50 i ps
Displacement probe 200 mils

Table 8 - Instrument Configuration Parameters

Parameter Description Value

Acquisition Determines how the Enpac 2500 collects a signature when the measurement definition specifies just one average.

Autoranging Sets the input range during data collection.

• If Autorang ing is set to Fixed or Aggressive, the sof tware integration is used on all FFT mea surements. This is to give improved dynamic range and

faster hardware settl ing 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.

Rockwell Automation Publication GMSI10-UM002D-EN-E - August 2012 45

Chapter 1 The Enpac 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 Enpac 2500 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.

Auto (default) Select to have the Enpac 2500 automatically select Normal or Slow depending on the measurements speed setting

specified by Emonitor.

Value Description

Select cmd: Default Exit this parameter without selecting an option.
Purge Marks all the points on the route as taken, sets the current reading to be the previous

reading for each point, and deletes all the Offroute data.

Delete route Deletes the current route in memory.

If you have an internal or SD storage card, the route to be deleted depends on what you
have chosen on the Setup Utility screen.

Delete all routes Deletes all routes and data in memory.

If you have an internal or SD storage card, the route to be deleted depends on what you
have chosen on the Setup Utility screen.

Initialize Formats the active memory. Note this will delete all routes and data in active memory.

TIP

Configure only when you open data collection. You must have a Route open for
the memory option to display. A Route must be in active memory.

Table 8 - Instrument Configuration Parameters

Parameter Description Value

Mach. Speed Controls the amount of time auto-ranging will wait to be sure it has seen the peak signal value of the sample.

When faster data collection is desired, set Autoranging to `Aggressive and Mach. Speed to `Normal.

Settling Delay The amount of time the instrument should delay data acquisition after

applying power to an ICP accelerometer.
The specified delay applies only to the first ICP measurement after

turning ICP on, for example, the first measurement at the start of a
ROUTE or a measurement following a non-ICP measurement

After the first measurement, data acquisition times are not affected. If

Value Description

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 suppor ts 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.

Fixed: Default The Enpac 2500 data collector uses the signal level entered in the point setup information (either Route or Offroute) as the

trigger point.

Adding Applications to the Enpac 2500 Data Collector

The Enpac 2500 data collector uses the Extension Manager to install and
uninstall application extensions and functions that are licensed and sold
separately from the basic entry level product (for example, Balancing and Two
Channel).

The installation cards that you receive from Rockwell Automation will work with
any Enpac 2500 data collector. Once an application is installed on an Enpac 2500
data collector, the card is locked so that it can only be used with that unit.

One installation card is required for each unit that will be upgraded.

You can uninstall applications if required. When uninstalling an application, you
have the option to free up the license so that it can be used to install the
application on another Enpac 2500 data collector. This allows applications to be
transferred between units.

Setting Up Measurements

This chapter describes setting up the measurement definitions in Emonitor to use
with the Enpac 2500. Measurement definitions define how to collect and store
measurements. You can create several different types of measurement definitions
at each location. Emonitor 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, Emonitor can shorten
the data collection time. This chapter describes also how the Emonitor software
and the Enpac 2500 handle alarms, lists, and inspection codes.

IMPORTANT

The names of the active data
collectors appear in inverse text.

Measurement Definition Options

These topics describe the available selections for setting up measurement
definitions in Emonitor. You determine these selections by choosing Tools > Set
Active Collectors in Emonitor.

Figure 7 - 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 Enpac is active, then only the valid choices for the Enpac appear
in the lists. If the Enpac 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 Enpac.

In some cases, both Emonitor and Enpac 2500 support certain options. In other
cases, Emonitor can support an option that the Enpac 2500 cannot support. For
example, Emonitor can apply a software high pass filter to the data after it
unloads the data from the Enpac 2500. This allows you to use a filter that is not
available in the Enpac 2500.

Measurement Types

Emonitor and Enpac 2500 support the following measurement definition types:

•Magnitude - This measurement type is a single value representing the total

energy of a measurement. For example, a vibration magnitude represents
the total energy in a vibration spectrum. The Enpac 2500 can also collect
magnitude+phase measurements, for the first through the eighth orders.

•Numeric - Manual entry or DC voltage measurement of an overall value

such as temperature, pressure, flow rate, operating speed, or proximity
probe gap readings.

•Spectrum - Frequency domain measurement of frequency vs. amplitude,

usually for velocity or acceleration. The Enpac can collect phase with
spectrum measurement definitions.

•Time Waveform - Time domain measurement of time vs. amplitude,

usually for displacement, velocity, or acceleration.

Remember that the available measurement types in Emonitor depend on the
active collectors you select with the Tools > Set Active Collectors. If you have two

IMPORTANT

or more active data collectors, you may not see all the selections available for the
Enpac.

Measurement Filters

Emonitor and Enpac 2500 each support certain measurement filters. Some of the
filters are supported in both Emonitor and Enpac 2500. You can define custom
band filters (high pass, low pass, band pass) by creating a new band filter using
Setup > Band Filter. You can choose to use a filter in the Enpac 2500 by selecting
the Analog or RSS (digital) option when you define a filter.

Figure 8 - Defining a Band Filter

Filters in Emonitor are referred to as software filters. Filters in data
collectors are referred to as hardware filters. Hardware filters alter the
signal in the Enpac 2500. Emonitor software filters alter the signal (data
representing the signal) after you unload the data into Emonitor. In
general, if the filter you want to use is available in both Emonitor and in the
data collector, it is to your advantage to use the hardware filter in the data
collector.

Hardware filters have the following advantage:

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.

Software filters have the following advantage:

If there is no corresponding filter in the data collector, or you choose not to
use it, Emonitor 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 the following measurement
definitions:

• Magnitude

• Spectrum

These six gSE filters are available in the Enpac 2500. If you select the Envelope
filter, Emonitor automatically picks the 5 kHz gSE filter.

100 Hz gSE (6000 CPM)
200 Hz gSE (12000 CPM)
500 Hz gSE (30000 CPM)
1000 Hz gSE (60000 CPM)
2000 Hz gSE (120000 CPM)
5000 Hz gSE (300000 CPM)

The Datapac Emulation parameter in the Data Collector Advanced Settings
dialog (Setup > Data Collector) in Emonitor must be set to Yes.

See Table 31 on page 100

.

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 Enpac 2500, and you cannot change them in Emonitor. You can use
ESP filters with the following measurement definitions:

• Magnitude

• Spectrum

The following ESP filters are available with Emonitor and the Enpac 2500.

0.6 to 1.25 kHz

1.25 to 2.5 kHz

High Pass Filters

Use a high pass filter to remove high vibration, low frequency signal components
that would dominate the signal. Examples include 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 Setup > Band
Filter. You can use a high pass filter with the following measurement definitions:

• Magnitude

• Spectrum

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.

Emonitor uses a high pass filter with one of the low frequency cutoff shown in
the table below. It uses the filter whose cutoff is greater than or equal to the result
of the 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. You can use order filters with the following measurement definitions:

• Magnitude

• Spectrum

You can define and use order filters for the first through the eighth orders with
the Enpac 2500. If you specify the Maximum frequency in Orders, select Analog
and Order normalize when you define the orders filters, then the Enpac calculates
the orders from an external trigger.

The Enpac 2500 then uses its own filters to calculate the magnitude and phase for
the first through the eighth orders. Emonitor calculates magnitude values
(without phase) for additional orders after you unload the data. Emonitor also
calculates magnitude values after you unload the data if you select None instead
of Analog.

If you want phase, remember to specify the Maximum frequency (in
Collection Specification dialog) in Orders, select Analog in the Band Filter
Specification dialog and Order normalize in the Collection Specification
dialog. Emonitor does not select these options by default.

Default Filters

There are also four default filters in Emonitor that map to specific filters in the
Enpac 2500. The filters are High Frequency, Envelope, Smart HP, and Overall.

•High Frequency - Typically this filter maps to a high frequency filter in

the data collector and is available only for magnitude acceleration
measurements. In the Enpac 2500, it maps to the 5 kHz gSE filter.

•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 Enpac 2500, it maps to the 5 kHz gSE filter.

•Smart HP - (Smart High Pass) Typically this filter maps to a specific high

pass filter in the data collector and is available for magnitude, spectrum,
and time waveform measurements. In the Enpac 2500, it maps to the
Enpac filters shown in the table below, depending on the results of
comparing the filter choice to the formula below.

Emonitor uses the following formula.

IMPORTANT

Select to use the RSS filter

The available filters in Emonitor depend on the data collectors you select as
active data collectors using Tools > Set Active Collectors. If you have two or
more active data collectors, you may not see all the selections available for
the Enpac. If you have no active data collectors, you see all the selections for
every data collector, not just the selections for the Enpac.

RSS Overall

The Enpac 2500 allows 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. Please note that the RSS overall values may not trend well with
analog overall measurements.

To use the RSS filter, you must create a Band Filter in Emonitor. Choose Setup >
Band Filter and click New. Then select RSS (digital) as the filter type.

Figure 9 - RSS Filter

Using the 0.36 Hz (21.6 CPM) low cutoff filter for integrated measurements
or the 0.18 Hz (10.8 CPM) low cutoff filter for non-integrated
measurements will always cause the Enpac 2500 to go into a long
autorange mode. Only use these filter settings when very low frequency
data is required.

Measurement Units

Emonitor and the Enpac 2500 support many different measurement units. The
measurement units that appear in the Enpac 2500 are text that depend on:

• the type of measurement definition.

• the units for the measurement definition.

• the transducer specification used in the collection specification for the

measurement definition.

uses the units that you select in Emonitor. You can select units from a single
system (for example, English g, in/sec, etc.), or you can mix units from different

2

systems (for example, English gs, in/sec and Metric m/s

, m/sec) in one list. The
Enpac 2500 loads the exact text string from Emonitor. The signal detection type
(peak, rms, true peak, etc.) is appended to the units on the Enpac 2500 screen.

The measurement units cannot be changed after you collect data for the
measurement definition.

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.

Measurement Input Types

The input type is part of the transducer specification (Setup > Calibration). The
transducer is part of the collection specification (Setup > Collection). You select
the collection specification when you set up the measurement definition.

Emonitor and the Enpac 2500 support the following input types.

• ICP Accel - Use for ICP accelerometers requiring current from a power

supply.

• AC Coupled - Use for AC voltage measurements and non-ICP

accelerometers.

• DC Coupled - Use for DC voltage measurements. This includes numeric

(process) measurements taken from a DC voltage output.

•Manual Entry - Use for numeric (process) measurements where you enter

the value for the measurement with the data collector keyboard.

To specify an input type, choose Setup > Calibration, then select the correct
Enpac from the Collector list. You can then assign Input types, Calibration, and
appropriate Units to the transducer you wish to use.

Measurement Window Types

The measurement window type is part of the collection specification (Setup >
Collection). See

collection specification when you set up the measurement definition.

Emonitor and the Enpac 2500 support the following measurement window
types. In general, the Hanning measurement window provides the best
compromise of frequency and amplitude accuracy for most predictive
maintenance measurements.

•Hanning - A general purpose window to use on random type data when

frequency resolution is more important than amplitude accuracy. Use this
setting for most of your machinery monitoring activities.

•Rectangular - The data collector does not apply a window. Use this only

for transient signals that die out before the end of the time sample, or for
exactly periodic signals within the time sample.

•Flattop - Use this when amplitude accuracy is more important than

frequency resolution. In data with closely spaced peaks, a Flattop window
may smear the peaks together into one wide peak. Use this setting for
sinusoidal or calibration signals.

•Hamming - A general purpose window that is similar to the Hanning

window. It provides better frequency resolution but decreased amplitude
accuracy when compared to the Hanning window. You can use it to
separate close frequency components.

Setting Up Collection Specifications on page 69. You select the

Measurement Signal Detection Types

The signal detection is part of the collection specification (Setup > Collection).

See

Setting Up Collection Specifications on page 69. You select the collection

specification when you set up the measurement definition.

Emonitor and the Enpac 2500 support the following signal detection types.

•None - Use for numeric measurements. None defaults to RMS when

applied to magnitude or spectrum measurement definition.

•RMS - Use for detection of voltage and current. For the frequency domain,

the dynamic signal is measured as the square root of the mean of the square
of the signal. This is the RMS amplitude of a sine wave at the frequency of
interest. For the time domain, the dynamic time signal is squared,
integrated over some time period, and then the square root is taken.

•Peak - Use for detection of acceleration, velocity, and high frequency

energy. This is the peak (0 to maximum) amplitude of a sine wave at the
frequency of interest and is calculated from the RMS value.

•Peak-Peak - Use for detection of displacement; sometimes used for high

frequency energy. This is the peak-to-peak (minimum to maximum)
amplitude of a sine wave at the frequency of interest and is calculated from
the RMS value.

Rockwell Automation Publication GMSI10-UM002D-EN-E - August 2012 71

Chapter 2 Setting Up Measurements

•True Peak - Use to detect impacts and random transients. The dynamic

time signal contains the absolute value of the largest peak (positive or
negative) within a specified time window. Returns a magnitude value only.
If used with a spectrum measurement, Emonitor uses a Peak signal
detection type instead. This value is not calculated but is measured
directly.

•True Peak-Peak - Use to detect impacts and random transients. The

dynamic time signal contains the absolute value of the largest peak to peak
distance within a specified time window. Returns a magnitude value only.
If used with a spectrum measurement, Emonitor uses a Peak-Peak signal
detection type instead. This value is not calculated but is measured
directly.

Measurement Maximum Frequencies

The measurement maximum frequency is part of the collection specification
(Setup > Collection). See Figure on page 69

You select the collection specification when you set up the measurement
definition. Emonitor and the Enpac 2500 support the following maximum
frequencies in Hz (CPM).

Number and Type of Averages

The number and type of averages are part of the collection specification (Setup >
Collection). You select the collection specification when you set up the
measurement definition. See

Emonitor and the Enpac 2500 support the following number and types of
averages for data collection.

•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.

Setting Up Measurements Chapter 2

Orders Track

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…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 Enpac 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.

To set up route points using Orders Track collection, follow these steps.

1. Create a collection specification in Emonitor that uses Orders for the

maximum frequency (Fmax). Also, check the Order Normalization
checkbox to signify Orders Track to the Enpac.

2. Create a Spectrum measurement definition that uses the Orders Based

collection specification.

3. Tag that measurement and load it to the Enpac with a list.

Rockwell Automation Publication GMSI10-UM002D-EN-E - August 2012 75

Chapter 2 Setting Up Measurements

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 Enpac 2500, you set up frequency items in Emonitor and download
them to the Enpac. Then, you can review the data using the Diagnostic
Frequencies cursor. This feature allows you to diagnose the peaks you see in the
Enpac using the frequency items from the host software.

In order to load the Diagnostic Frequency labels, you must check the Load
Frequency Labels checkbox in the Load Options dialog.

Setting Up Speed References

The Enpac can determine the speed using speed references in Emonitor. The
speed reference value is used by the frequency items to calculate the Fmax of the
dependent measurements.

To set up speed references in Emonitor, double-click in the RPM column in the
Location pane. The following dialog appears.

76 Rockwell Automation Publication GMSI10-UM002D-EN-E - August 2012

Setting Up Measurements Chapter 2

TIP

These options are not supported in the
Enpac 2500.

You can choose a frequency reference item as your machine speed reference. This
allows for machine speeds to be stored and retrieved dynamically. The Enpac
supports two types of frequency types: speed reference and linear rotational.

If you want to use a collected measurement from the Enpac 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.

• 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 Enpac 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.

Emonitor 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
machines speed.

To set up the Speed Reference Frequency for the Enpac, double-click in the
Definition column in the Speed Reference row in the Frequency Item pane. The
Speed Reference Frequency dialog appears.

Rockwell Automation Publication GMSI10-UM002D-EN-E - August 2012 77

Chapter 2 Setting Up Measurements

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 .

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 allows you to set up a rotational frequency item based on a linear
speed. .

Setting Up Measurement Definitions

Press F1 to find out more information about each option in this dialog.

The topics in this section describe setting up different types of measurement
definitions in Emonitor for your data collector. The topics describe the way
Emonitor works with the Enpac 2500 for each different type of measurement
definition. These include answers to questions such as:

• How does Emonitor handle measurement units and alarms available in

Emonitor but not supported in the Enpac 2500?

• How many orders of magnitude and phase can the Enpac 2500 collect?

• How does the Enpac 2500 support collecting a spectrum when a

magnitude measurement is in alarm?

Emonitor combines measurement definitions when it creates a load file from a
list of measurement definitions. For example, Emonitor 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
since you do not have to start each measurement individually. For more general
information on setting up measurement definitions, see the Emonitor online
help.

Magnitude Measurement Definitions

Emonitor and the Enpac 2500 support magnitude measurement definitions.
This topic lists the unique characteristics of the Enpac 2500 that you may need to
know when setting up and collecting magnitude data.

Measurement Units Not Supported in the Enpac 2500 Data Collector

• Magnitude measurement definitions with unit not supported by the

Enpac 2500 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

page 68.

Magnitude Alarms in the Enpac 2500 Data Collector

• The Enpac 2500 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 Enpac 2500 during data collection.

• For more on how Emonitor combines alarms before sending them to the

Enpac 2500, see Alarms and the Data Collector

Measurement Units on

on page 95.

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. This forces the Enpac 2500
to collect a spectrum measurement. After you unload the measurement,
Emonitor calculates the magnitude values in the bands from the spectrum.

If your measurements include both magnitude and phase, the Enpac 2500 can
collect up to eight orders. If your measurements include magnitude only, the
Enpac 2500 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.

Dynamic (AC) component

• Set up a displacement transducer in the Transducer Calibration dialog

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.

Rockwell Automation Publication GMSI10-UM002D-EN-E - August 2012 79

Chapter 2 Setting Up Measurements

• Set up a Collection Specification with Transducer set to the AC

displacement and Signal detection set to Peak-peak.

• 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.

Static (DC) component or gap

• Set up a displacement transducer in the Transducer Calibration dialog

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 transducers calibration by 2.5.

• Set up a Collection Specification with Transducer set to the DC

displacement and Signal detection set to ‘RMS.’

• 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’ since any type of high pass filtering removes the DC
component.

Magnitude and Phase Measurements at Orders

Emonitor and the Enpac support collecting the magnitude and phase at orders.
This topic describes the steps to set up measurement definitions to collect
magnitude and phase with the Enpac. There are several things you may need to
know about collecting magnitude and phase at orders.

• You must select Also collect phase data in the collection specification to

collect phase.

• You must select Analog when you define orders filters. The Enpac

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
Enpac collects a spectrum and Emonitor calculates the magnitudes after
unloading.

• When collecting magnitude and phase at orders, the Enpac always collects

a spectrum measurement, and then calculates the magnitude and phase
values from the spectrum.

• The Enpac can collect phase only at the first through eighth orders.

• The Enpac can collect magnitude only at the first through the eighth

orders. If you request additional orders, Emonitor calculates magnitude
values at additional orders from the spectrum after unloading the data.

• The Enpac may collect more orders than requested, but it does not collect

fewer than requested. Only the requested values are unloaded into
Emonitor.

• The Enpac may display a phase value that differs from the value that

appears in Emonitor by up to one degree.

Rockwell Automation Publication GMSI10-UM002D-EN-E - August 2012 81

Chapter 2 Setting Up Measurements

IMPORTANT

• Phase and magnitude measurements at orders require a trigger signal. 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 determines whether you also want to collect phase as well as magnitude
data.

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, m/s2, ips, mm/s, mils, um, or V.

3. Select the measurement filter. To 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.

Refer to

Measurement Filters on page 63 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. If you do not
center the band filters, magnitude and phase readings may not be accurate.

4. Select the collection specification. You must check the Also collect phase

data checkbox in the Collection Specification dialog so the data collector
collects phase at orders.

5. Select the storage specification. The first measurement definition is now

complete.

6. If you want to create more than one measurement, copy the measurement

definition by selecting the correct row and choosing Edit > Copy.

7. Move down to the next empty row in the measurement definition

spreadsheet, and choose Edit > Paste to paste the copied measurement
definition.

8. Edit the new measurement definition by changing the measurement filter.

Select a band filter centered on the next order.

9. 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

Emonitor and the Enpac 2500 support numeric measurement definitions. This
topic lists the unique characteristics of the Enpac 2500 that you may need to
know when setting up and collecting numeric data.

Measurements Units Not Supported in the Enpac 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 Enpac 2500 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 Enpac 2500.

• For a list of support measurement units, see Measurement Units

page 68.

Full Scale Values for Numeric Measurements in the Enpac 2500 Data Collector

• The full scale value in the Enpac 2500 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 Enpac 2500 assumes a full scale value of 10,000.

• A full scale value of 10,000 can be a problem 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 Enpac 2500 may round the
value off. If you enter 0.01 with a full scale value of 10,000, the Enpac 2500
stores it as a 0 (zero).

Temperature Measurements

• Set up a temperature measurement definition by setting Data Type to

‘Numeric’ and Units to ‘RPM,’ ‘CPM,’ or ‘deg. C.’

• Set up the temperature transducer in the Transducer Calibration dialog

Machine Speed (RPM) Measurements

• Set up a tachometer measurement definition by setting Data Type to

‘Numeric’ and Units to ‘RPM,’ ‘CPM,’ or ‘Hz.’

• Set up the tachometer transducer in the Transducer Calibration dialog

with Input type set to ‘ICP Accel’ for either the internal laser tachometer
or an external TTL device (such as entach laser sensor, an optical trig ger, or
a strobe light with TTL output). Set the Input type to ‘AC Coupled’ or
‘DC Coupled’ if your speed sensor has an AC or DC voltage signal
proportional to speed. Set Units to ‘RPM,’ ‘CPM,’ or ‘Hz.’ Make sure you
enter the Calibration value that converts the voltage to speed.

• 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.

• Connect the speed sensor to the trigger connector on the Enpac 2500

when collecting data.

Magnitude Alarms in the Enpac 2500 Data Collector

You can use magnitude alarms with numeric measurements.

• The Enpac 2500 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

Enpac 2500 during data collection.

• For more on how Emonitor combines alarms before sending them to the

Enpac 2500, see

Alarms and the Data Collector on page 95.

Spectrum Measurement Definitions

Emonitor and the Enpac 2500 support spectrum measurement definitions. This
topic lists the unique characteristics of the Enpac 2500 that you may need to
know when setting up and collecting spectrum data.

• The Enpac cannot collect phase with a spectrum measurement definition.

In other words, do NOT check the Also collect phase data checkbox in the
Collection Specification dialog.

• You can choose to have the Enpac 2500 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 to ‘On
Magnitude Alarm’ for the storage specification for the spectrum
measurement definition.

Time Synchronous Averaging in the Enpac 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 non­synchronous effects.

For more on supported averaging in the Enpac 2500, see

Setting Up Measurements Chapter 2

Order Normalized Spectra in the Enpac 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

Enpac 2500.

• Set 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 Enpac 2500 may collect more orders than required. For example, if

you set the Maximum frequency to ‘10 Orders,’ the Enpac 2500 may
collect more than ten orders. The Enpac 2500 always collects at least the
number of orders you request in the Collection Specification.

• The Enpac 2500 displays an order normalized spectrum. If the Collection

Specification dialog has the Also collect phase data checkbox checked, and
if the Maximum frequency is eight orders or less, the table on the Enpac
2500 screen shows the magnitude and phase values at each order. If the
Collection Specification dialog does not have the Also collect phase data
checkbox checked, or if the Maximum frequency is more than eight orders,
the table on the Enpac 2500 screen shows magnitude values only. The
Enpac 2500 displays a maximum of eight orders in the table.

If the table has eight orders or less, the Enpac 2500 arrow keys move the
spectrum cursor. If the table has more than eight orders, the Enpac 2500
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.

• Set up a displacement transducer in the Transducer Calibration dialog

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.

• Set up the Collection Specification to include the displacement

Transducer, and set the Signal detection to ‘Peak-Peak.’ You also need to
select the window, frequency range, and averaging options.

• 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.

Chapter 2 Setting Up Measurements

Spectrum Alarms in the Enpac 2500 Data Collector

The Enpac 2500 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. Set the Collect and store condition in the
Edit Storage Specification dialog to ‘On Magnitude Alarm’ for the storage
specification for the spectrum measurement definition.

• You must set Trigger to ‘Yes’ for any alarms you want to appear in the

Enpac 2500 during data collection. If you set Trigger to ‘Yes’ for two or
more alarms for the same measurement definition, Emonitor combines the
alarms before sending the combined alarm to the Enpac 2500.

For more on how Emonitor combines alarms before sending them to the
Enpac 2500, see

The Enpac does not support spectrum alarms. You can still set up the alarms for
the spectrum measurement definitions. Emonitor tests the data against the
alarms after you unload the data.

Time Waveform Measurement Definitions

Emonitor and the Enpac support time waveform measurement definitions. This
topic lists the unique characteristics of the Enpac that you may need to know
when setting up and collecting time waveform data.

• The Enpac 2500 cannot collect phase with time waveform measurement

definitions.

• You can choose to have the Enpac 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 to ‘On
Magnitude Alarm’ for the storage specification for the time waveform
measurement definition.

• The Enpac 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) 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 (Setup > Collection
Specification).

If your Maximum frequency is specified in CPM, convert CPM to Hertz
using this formula.

Setting Up Measurements Chapter 2

Combining Measurement Definitions for a Location

You can use Emonitor to set up many different measurement definitions for data
collection at a location. These can include magnitude, spectrum, time waveform,
and numeric measurements. You can then select the measurement definitions you
want to load to the data collector by creating a list of those measurement
definitions. When you want to load the data collector, Emonitor builds a load file
containing the measurement definitions in the list.

Emonitor combines measurement definitions at each location to make data
collection more efficient. This allows you to collect two or more measurements
automatically, without having to start each measurement separately. The rules for
combining measurement definitions depend on several factors. In general,
however, Emonitor can combine measurement definitions at the same location
when they have the same:

• Measurement units (part of the measurement definition)

• Measurement filter (part of the measurement definition)

• Transducer calibration and input type (from the transducer specification

used in the measurement definitions collection specification)

In addition, there are some specialized cases that allow or prevent Emonitor from
combining measurement definitions from the same location when they meet the
above conditions.

• In general, Emonitor cannot combine a magnitude and a spectrum

measurement if they have different measurement filters.

• Emonitor can combine an envelope acceleration magnitude measurement

with a spectrum with the same units.

• Emonitor can combine a non-filtered measurement definition with a high

pass, low pass, or band filtered measurement when the band filter is
applied by Emonitor after the spectrum is unloaded.

• Emonitor can combine two signatures if they are the same type (time, fixed

frequency spectrum, order normalized spectrum) and the same resolution.

Chapter 2 Setting Up Measurements

TIP

Setting Up Tri-axial Measurements

You can set up and collect tri-axial measurements with the Enpac 2500 if you
have a tri-axial transducer and a special tri-axial cable for your Enpac. This allows
you to collect measurements in three directions without moving the transducer.

Tri-axial measurements require setting up separate locations, and measurement
definitions for each of the three transducers. This section shows the method for
setting up these measurements.

To Set Up Tri-axial Locations and Measurement Definitions

You must set up a different location for each axis of a tri-axial transducer.
The tri-axial data is multiplexed one direction at a time.

1. Open the Database window by choosing Window > Database.

2. Select the Measurement view and click OK.

3. Select the machine in the Hierarchy Tree for which you want to set up tri-

axial measurements.

4. In the Location pane, choose View > Pane Options to add the Lo. Channel

column to the Location pane. Press F1 in the Pane Options dialog for
assistance.

5. Create a Location for the first tri-axial measurement and set Lo. Channel

to ‘1X.’

6. In the Measurement Definition pane, create the measurement definition

for that location.

7. Select the location you just created. Choose Edit > Copy to copy the

location.

8. Move to an empty row in the Location pane and choose Edit > Paste to

paste the location into the spreadsheet.

9. Edit the new location to change the Direction and set Lo. Channel to ‘1Y.’

10. Repeat steps 7 and 8 to copy and paste the third location into the Location

pane. Edit the new location to change the Direction and set Lo. Channel
to ‘1Z.’

The Location ID and Position must be the same for all three tri-axial
measurements.

11. Now include these measurement definitions in a list. You can create a new

list or recall the current list.

The locations must be tagged in order to create a group list.

12. Add the three locations to a group list by double-clicking the Group

column in the Location pane. The current group number appears in the
Group column. Make sure you assign the locations to the same group
number. The group is then loaded with the list to the Enpac 2500.

Setting Up Alarms, Lists, and Inspection Codes

This section describes the way Emonitor loads alarms, lists, and inspection codes
into the Enpac 2500. For more information on alarms, lists, and inspection codes,
see the Emonitor online help.

Alarms and the Data Collector

Emonitor and the Enpac 2500 support loading alarms with the list of
measurement definitions to the data collector.

Selecting Alarms to Load to the Enpac 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
Emonitor.

• If you set Tr igge r to ‘Yes‘ for two or more alarms for the same
measurement definition, Emonitor combines them to make a single alarm.

Supported Alarms with the Enpac 2500 Data Collector

This list describes alarms the Enpac 2500 supports, alarms it does not support,
and substitutes for some of the unsupported alarms.

• The Enpac 2500 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 Emonitor. You
must create one by combining an above and a below alarm for the same
measurement definition. Emonitor creates an out of window alarm when
it builds the load file if both alarms are active.

• The Enpac 2500 does not support spectrum (narrowband) alarms for
spectrum measurements. You can still set up spectrum alarms with
spectrum measurement definitions. Emonitor tests the measurements
against the alarms after you unload the data.

Rockwell Automation Publication GMSI10-UM002D-EN-E - August 2012 95

Chapter 2 Setting Up Measurements

For unsupported alarms, Emonitor tests the measurements against the alarms
when you unload the data collector. This means that Emonitor 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.

Lists and the Data Collector

Emonitor and the Enpac 2500 support loading lists of measurement definitions
to the data collector.

Inspection Codes and the Data Collector

Emonitor and the Enpac 2500 support loading inspection codes to the data
collector.

Inspection Code Support in the Enpac 2500 Data Collector

• You can load inspection codes into the Enpac 2500 only with a list.

• You can use only the inspection codes loaded with the list with

measurements in that list. This includes both measurements in a list and
unscheduled measurements associated with that list.

• You can load up to 100 inspection codes into the Enpac 2500. Emonitor

numbers the inspection codes from 1…100. The Enpac 2500 numbers the
inspection codes from 00…99.

• The Enpac 2500 displays the first 16 characters of each inspection code.

Loading Inspection Codes to the Enpac 2500 Data Collector

You can load and remove inspection codes.

• You must load the inspection codes when you load a list. You do this by
selecting Load inspection codes in the Load Options dialog . If you do not
select this option, no inspection codes are available for measurements from
the list or for unscheduled measurements associated with the list.

You can remove the inspection codes from the Enpac 2500 by initializing the data
collector.
