In regard to data acquisition systems, the following terminology is used throughout this

manual:

ZonicBook refers to a ZonicBook/618E.

Medallion refers to any of the three ZonicBook-Medallion models.

WaveBook refers to WaveBooks in general, except when a specific model isspecified.

Reference Note:The information provided in this manual applies to ZonicBook, Medallion, and WaveBooksystems with exceptions as noted. Refer to your system’s specific hardware documentation

in regard to hardware setup.

What is eZ-TOMAS?

eZ-TOMAS (Total Online Monitoring and Analysis Software) is designed to collect vibration and processdata from rotating machinery. eZ-TOMAS can simultaneously monitor, acquire, store, and display data

from Medallion, ZonicBook, and WaveBook systems.

The signals to be acquired are typically associated with a specific machine train. The analog inputs can be

any combination of Proximity, Velocity, Accelerometer, Tach, or DC proportional voltage signal. Up tothree tachometer signals are supported.

Tips for Using eZ-TOMAS

The following suggestions should make your use of eZ-TOMAS more efficient.

1. For Medallion only: Make sure your Medallion’s Dip Switches are configured correctly.Typically: Single Ended, AC coupled, and ICP ON.

2. For Medallion and WaveBook: Use a standard channel location convention.Typically: A single Tach is used at channel 8.

3. For ZonicBook: Tachometers are typically connected to tach-designated input channels.

A Look at the Gauge Window & Control Pull-down Menu

The Gauge Display Window is used to show real-time values and measurement status. Gauge Display is

not used for historical data analysis. A Data Display Window, discussed elsewhere, is used to analyze real-time and historical data.

The Gauge Display Window’s Control pull-down menu repeats the functions of the Gauge window’s lower

panels. For example, menu selections can be used in place of several Option panel buttons, as well as thetoggle switches and snapshot button. The menu provides a means of displaying high and low peak values,

gauge values, a machine image, and a list of eZ-TOMAS projects. The menu and its functions are depictedon the Gauge window figure on the following page.

The main window of the GUI (graphical user interface) includes a set of virtual gauges, which use one of

10 spectral bands, discussed shortly. There will always be a vertical gauge associated with each input

channel. When the 1x Amp/Phase selection is made, spectral bands for “1x Amplitude” and “1x Phase” aresimultaneously displayed, with the later being in a circular phase gauge (see second figure).

In addition to spectral band gauge displays, eZ-TOMAS can interactively display data in a variety of other

formats, including: Orbit, Polar, Time, Bode, Cascade/Waterfall, Strip Chart, and Shaft Centerline.

You can “mouse-clicks” on the gauges to:

Bring up the Limit Configuration Window.

Bring up the Input Channels Tab (on the Setup Configuration Window). This cannot be done

from circular phase gauges.

Drag limit-pointers on vertical gauges to new positions, thus setting new limit values.

Drag limit-lines on circular phase gauges to new positions, thus setting new values for the phase

angle limits.

Although the configuration windows and limits are discussed later, an explanation of how to access them

from the gauges directly follows.

10/94

The data acquired by eZ-TOMAS and the supporting configuration information are stored in user-defined

files. This allows a single eZ-TOMAS system to be used with several different machines. The acquireddata is stored according to user-defined event changes, e.g., time, overall, and rotating speed.

Acquisition, instrumentation, and storage configuration parameters are also definable. These parameters

are stored over time. Configuration changes do not invalidate previously acquired data.

Functions of the Control Pull-Down Menu

The straight-forward functions of Control Pull-down menu are depicted in the above figure. The shaded

numbers in the menu relate to the corresponding non-shaded numbers. The functions, which are self-descriptive by name, are as follows:

1) Acquisition – can be use to turn the acquisition on or off, just as can the acquisition toggle switch.

2) Limit Check – can be used in the same manner as the Limit Check toggle switch.

3) Digital I/O – can be used to turn Digital I/O on or off. Same functionality as the Digital I/Otoggle switch.

4) Save Snapshot – A data storage trigger that can be used instead of the “camera” button. Theduration of the data collection is set in the Storage Tab of the Setup Configuration window

[accessed via the Edit pull-down menu].

5) Show Peak Holds – Used to display [or hide] high and low peak markers.

6) Show Gauge Values – Used to display [or hide] gauge values.7) Show Machine Graphic – Used to show or hide a graphic. The image can be positioned

anywhere on the screen.

8) Show TOMAS Projects – Accesses a list of projects and their associated directory locations.



11/94

The Spectral Bands and Tachs

Most of the Gauge window is occupied by gauges which display values for spectral bands and tachometers.Selection of the band types and the tachs can be made from the “Gauges” pull-down menu.

Gauges Pull-down Menu

To select a spectral band with the mouse, open the Gauge pull-down menu, then place the mouse cursor

over the selection and click on it. In the preceding figure, Overall has been selected. Note that the Overallvalue is a time domain overall value.

The Overall, DC Gap Voltage, 1x Amp, and 1x Phase spectral bands cannot be modified. In regard to

probe values:

Displacement probe measurements are displayed as peak-to-peak values.

Velocity probe measurements are displayed as zero-to-peak values.

Accelerometer probe measurements are displayed as zero-to-rms values

You can define the parameters of User Defined bands 5 through 10 in the Setup Configuration window.

To define a parameter:

1. Open the Edit pull-down menu.

2. Select Setup.

3. From the Setup Configuration window select the Spectral Bands tab.

4. Set the parameters of the User Defined bands.

The Limit Check panel contains a toggle switch and an alarm log progress bar. The Limit Check toggle

switch determines the ON/OFF status of the Limit Checking feature. Click this toggle switch to turn limit

checking ON (Up/Green), or OFF (Down/Red).

The Alarm Log Progress Bar graphically indicates how full the Alarm File is.

Double-clicking on the bar, or on its associated text, opens the Alarm Log. The log can also be accessed

from the Reports pull-down menu. The most recent alarm event will appear below the bar.

Digital I/O Panel

The Digital I/O Panel contains an ON/OFF toggle switch and four push buttons. The push button iconsindicate the current status of the digital I/O. Each time you start eZ-TOMAS, the switches will be turned

off and appear gray. The Digital I/O toggle switch must be turned “ON” to enable digital I/O functionality.

If the DIO toggle switch is turned on, Digital I/O relay switches will activate [or deactivate] depending on

the configuration set in the Digital I/O Configuration window (detailed in chapter 4). The window is

accessible via the Edit pull-menu.

During an acquisition you can manually activate each of the four switches by clicking on the associated

button.

Note that in the following figure, the Digital I/O push buttons are as follows.

Data Storage Panel

The Data Storage Panel is easily recognized by its Snapshot [camera] button and the bar for Current Data

Record / History File Size.

The bar graphically indicates how full the FIFO file is. Two numbers, separated by a slash, reside just

below the progress bar. In the example this is 500 / 500. The first number is the current data record

number; the second is the number of records that can be stored in the FIFO file, also referred to as the

History File Size. In this case the data file is full.

Clicking the (camera) button will save “N” seconds of data to the history file; where “N” is

defined in the Storage Tab [in the Configuration Panel]. The data storage panel includes the Historical DataFile Date Range.

Note that you can open the Plot Window from this panel by double-clicking on the capacity bar, the record

Creating a Project

An eZ-TOMAS Project is a collection of data files, typically associated with a monitored machine. The

data files include configuration and measured data. When eZ-TOMAS runs it attempts to open the last

eZ-TOMAS Project accessed.If you are monitoring a machine for the first time, you should create a new eZ-TOMAS Project to store the

machine’s configuration and vibration data. If you have already created an eZ-TOMAS Project for themachine, use the File Open menu to pick up where you left off.

The vibration data files have a FIFO design. When you turn on the acquisition switch, data will be

appended to the data files.

Fig. 1 Gauge Panel for 24 Input Channels – First Row (Channels 1 through 8) is selected for gauge display

In Fig. 1 we see that Accel Ch 1 through Accel Ch 8 are being displayed. Channels 5, 6, and 7 would also be displayed, but

have been removed from the figure for clarity. In addition, the vertical gauges have been greatly compressed.

Below the gauges we see 3 rows of data cells. The top row provides data for Channels 1 through 8, the second row displaysdata for channels 9 through 16, and the third row displays data for channels 17 through 24. Up to 7 rows (channels 1 through

56) can be displayed.

We know that gauges are being displayed for channels 1 through 8. But suppose we wanted to see the gauge for channel 11?

A single click on the associated cell [in the second row] accomplishes this task. Simply single-click on the third cell in the

second row to display the gauge for Accel Ch 11. In the following figure we see that channel 11’s gauge replaced thechannel 3’s. This is because each of the 8 columns can display a gauge for only one channel at a time. Thus, column 3 is

home to channels 3, 11, and 19. The third gauge from the left can only display one of those channels at a time.

Fig. 2 - Displaying Accel Ch 11 in place of Accel Ch 3Note “A” - Single click on a cell to display the gauge for that cell.

If we wanted to change our display to show an entire different set of gauges we could single click on individual cells; or we

could double-click on any cell in a row to display guages for all the channels in that row (see Fig. 3).

Fig. 3 - Selecting a New Set of Eight Gauges

Note B - Double-click on any cell in a row to display gauges for all channels in that row.

Notice the second row of data cells in Fig. 3. Double-clicking on any cell in that row causes all 8 channels in that row tohave a gauge display. The gauge for Accel Ch 1 has been replaced with a guage for Accel Ch 9, the gauge for Accel Ch 2

has been replaced with a gauge for Accel Ch 10, etc. If we double-clicked on a cell in the third row we would see gauges

displayed for channels 17 through 24.

Configuring the Project

A default configuration is automatically loaded when you open an eZ-TOMAS file. However, you may

want to make some changes to the configuration. To make changes:

1. From the eZ-TOMAS Main Window, open the Edit pull-down menu.

2. In the Edit menu select Setup. The Setup Configuration window will appear.

Reference Note:The four tabs of the Setup Configuration window are labeled: Acquisition, Input Channels,

Spectral Bands, and Storage. They are discussed briefly in this section and in detail at the beginning of Chapter 4, Edit Menu.

3. Make sure that the Hardware panel reflects the correct device, e.g., ZonicBook/618E.

Setup Configuration Window, Acquisition Tab

Clicking the button will undo all the changes you’ve made since you

opened the Setup Configuration Window.

4. Make the desired changes for each of the tabs and then click the button.

You can start monitoring immediately.

Acquisition Tab – From the Acquisition tab you can set up parameters that include, but are not limitedto: Block Size, Analysis Frequency, Low Cutoff Frequency, FFT Window, and Number of Averages.

Input Channels Tab – From the Input Channels Tab you can change channel parameters. Thisincludes, but is not limited to assigning channel types, customizing channel names, setting the instrumentrange per channel, and assigning units.

Spectral Bands Tab – From the Spectral Bands Tab you can modify “User Defined” bands 5 through10 according to your application. Note that Overall, DC Gap V, 1x Amp, and 1x Phase bands are

predefined and cannot be modified.

Storage Tab - From the Storage Tab you can specify how you want trigger data storage. If any oneevent is triggered, data from all channels is stored. Data storage events are triggered when a change occurs

in the monitored machine’s condition. The basic idea is to activate storage based on Time Change and/or

Speed Change and/or Amplitude Change.

Refer to chapter 4 for more information regarding the Setup Configuration tabs.



20/94

Starting an Acquisition

After you configure your eZ-TOMAS Project, click the Toggle Switch to place it in the upright position. This starts the data acquisition. The switch is located in the

in the lower left corner of the eZ-TOMAS gauge window.

When acquisition is active, real time overall values are displayed in the instrument gauges.

The toggle switch is green while data acquisition is active.

To stop data acquisition, click the switch toggling it down (red).

Viewing Spectral Bands

The Main Window’s gauges can be used to display different spectral bands. On the View menu select the band of interest, e.g., Overall, DC Gap V, 1x Amp, 1x Phase, or one of the User Defined bands. Note that

selecting 1x Amp or 1x Phase results in two gauge types. In both cases vertical gauges will display for

1x Amplitude and circular phase gauges will display for 1x Phase. This is done automatically since the two

spectral bands are closely related.

Spectral Bands

Plotting Data

Click on “Display” in the main window’s menu bar, then select “Plots.” The Data Display Window

will open. Note that you can double-click on a gauge to open the Data Display Window to plot data forthat specific channel.

Multiple Plots

1. On the File pull-down menu of the Plots window, select Open Plot Window.This opens a second display window.

2. On the Window pull-down menu of the Plots window, select either Tile Vertically orTile Horizontally.

All display windows will be shown simultaneously.

Viewing Reports

eZ-TOMAS can generate the following types of reports, which are accessible from the Display pull-down

menu.

Display Pull-down Menu

The Statistical Report lists the historical spectral band data. It includes the instrument, the engineering

units, the minimum value, the mean average value, the maximum value, and the standard deviation bychannel. Statistical reports can be used to automatically generate limit values based on historical data.

The Alarm Log is a record of the last “N” number of alarm events. The number of alarms was specified in

the Setup Configuration window under the Storage Tab. The Alarm Log includes the date and time, the

channel number, reference tachometer, instrument name, spectral band type, alarm type, and value of thealarm signal.

The Snapshot Log can be accessed from the Reports pull-down menu, or from the History Data Window.

The Snapshot Log file contains entries which were created whenever the user clicked the

button, which is located in the Gauge Window’s Data Storage panel.

The Generate Report using Microsoft Excel option is available beginning with eZ-TOMAS version5.0.x. The feature allows you to generate a report using Microsoft Excel 2000 (version 9.x) or later.

An XL Report generation dialog box allows you to format the report and specify its contents.

Selecting Configuration Setup from the Reports pull-down menu creates a text file that contains

configuration details of the current project.

Acquis it ion Tab

Acquisition Tab

The Acquisition tab is used to configure how the data will be acquired and processed. A breakdown of

the panel tabs follows.

eZ-TOMAS 947394 Edit Menu 4-1

You must turn acquisition off and then on again for Acquisition Configuration changes

to take effect.

Panels of the Acquisition Tab

Hardware

The Hardware Panel has a pull-down list from which the applicable

data acquisition device must be selected; i.e., WaveBook, ZonicBook,or Medallion.

dB Reference

This panel is used to set the 0 dB reference point in Engineering Units(EU). The EU value for 0 dB reference is used with microphone inputchannel types. The default setting is 20 micro-Pascals (0.000020 pa).

Acquisition

Analysis Frequency (Hz) The maximum frequency of interest. Thesampling rate will be 2.56 times the analysis frequency. Verify the

maximum frequency response of your probes. For a Tach signal,your Analysis Frequency should be a higher multiple of the maximumrotating speed. Typically, this multiple is at least 10 times the rotatingfrequency.

Spectral Lines The number of lines per spectrum and the number ofdata samples used in the FFT (Fast Fourier Transform) process. Themore spectral lines, the greater the data resolution. As the number ofspectral lines increases, so does the time that it takes to collect thedata and the amount of disk space.

Overlap Data Acquisition For slow speed data acquisitionapplications, you have the option to select overlap data processing tospeed up real time data displays. This option is enabled when the

Acquisition Time is greater than 2 seconds.

If you select Overlap Data Acquisition, eZ-Tomas will automaticallydetermine the overlap percentage needed to achieve a 1 to 2 seconddisplay update rate. For example, if your analysis frequency is500 Hz and you have 3200 spectral lines, the acquisition time is 6.4seconds. With Overlap Data Acquisition, the overlap percentage willbe 75% and the update rate will be 1.6 seconds. (6.4 sec / 4). Thedivisor is a power of 2.

Number of Averages The number of data blocks averaged before ablock of data is accepted and displayed. Typically, the value is “1”indicating no averaging.

FFT Window Fast Fourier Transform. FFT is an efficient techniquefor calculating the frequency of components in a time-domainwaveform based on digitized voltage measurements. The result is adisplay of amplitude versus frequency and phase versus frequency.The FFT Window is a weighting window, typically either Hanning orFlat Top. Hanning provides better frequency resolution. Flat Topprovides better amplitude resolution.

Note: Filter Panels apply to ZonicBook/618E and WBK18 channels. Filter Panel functionality does not applyto WaveBook direct channels or to Medallion channels.

High Pass Coupling Filter (Hz)

High Pass Filter (AC Coupling): When AC Coupling is selected inthe Input Channels tab, the associated input signals will pass througha 0.1 Hz or a 1 Hz High Pass Filter, depending on which radio buttonis selected.

High Pass Display Filter (Hz)

Allows you to eliminate the lower frequencies from the full frequencyrange for “no,” “single,” and “double” integrations by entering thedesired cutoff value in Hz. All data points that exist below thespecified value are set to zero.

Integration Units

Accelerometer and Velocity signals can be integrated. Select the

desired integration value (g’s/ips/mils, g’s/ips/in, or g’s/mmps/mm).Points to note:

(1) If the signal is acceleration, then(a) single integration results in velocity, and(b) double integration results in displacement .

(2) If the signal is velocity, then single integration results indisplacement .

(3) The type of integration (none, single, or double) is selected in theInput Channels tab.

Terms and factors related to the Acquisition Panel

Nyquist Factor In eZ-TOMAS waveform frequency is multiplied by a nyquist factor of 2.56. Thisensures that a sampled analog signal is accurately reconstructed. The 2.56 nyquistfactor is the most efficient in FFT Analysis.

Sampling Rate A rate that is 2.56 times the Analysis Frequency. If the Analysis Frequency was1000 Hz and if the Spectral Lines was 800 lines; then the Sampling Rate would be2560 samples per second. This rate would apply to each channel. Derived from:

Analysis Frequency x 2.56 = 1000 x 2.56 = 2560.

SpectralResolution

A value related to Analysis Frequency and Spectral Lines. Where SpectralResolution equals the Analysis Frequency divided by 2.56. If the Analysis Frequencywas 1000 Hz and if the Spectral Lines was 800 lines; then the Spectral Resolutionwould be 1.25 Hz per spectral line.

Derived from: Analysis Frequency divided by Spectral Lines = 1000 Hz / 800 = 1.25 Hz

Input Channels Tab

This tab is used to configure each channel for your project. The available setup options in this window aredependent on the instrument type selected.

Input Channels Tab, Showing the Leftmost Column

To configure a channel:

1. Select the channel to be configured.2. Set the instrument type.3. Set the value for each attribute of the channel.

Repeat this process for each channel.

The parameters of one channel can be copied to another channel by usingoptions on the Edit menu.

Medallion Users Only: Configure the Dip Switches for each probe, according to probe

type. For details refer to the Medallion user’s manual (p/n 1086-0901).

Input Channels Tab Column Functions

No. is the channel number. Selecting the channel number highlights all attributes for thatchannel.

Type is the type of instrument attached to the channel. Options are:

o Accelerometer

o Velocityo Displacemento Statico Tach

o Microphone

o Pressureo Generalo Unused (select “Unused” for channels that

have no instrument attached.)

Name is a Label you will use to identify the channel.

Gauge Min,

Gauge Max

represent the instrument range minimum and maximum gauge values.

Units is the Engineering Units you want to use. Options depend on the instrument type.



33/94


Accelerometer and Velocity signals can be integrated. This column is used to select thetype of integration (none, single, or double). Points to note:

(1) If the signal is acceleration, then

(a) single integration results in velocity, and(b) double integration results in displacement.

(2) If the signal is velocity, then single integration results in displacement.

Integration

(3) The integration value (g’s/ips/mils, g’s/ips/in, or g’s/mmps/mm) is selected in the

Acquisition Tab.

mV / EU is the instrument sensitivity. (Typical displacement probes: 200 milli-Volts per mil.Typical accelerometer probes: 100 milliVolts per G. For Tach probes

enter 1000.) For static channels, this property represents the slope variable (m) of the

linear equation y = mx + b.

Offset Sets the offset factor that is to be applied to the Engineering Units.

FSV FSV (Full Scale Voltage) is the maximum input voltage for the instrument. If you areunsure of the instrument’s maximum voltage value, select a high voltage value.

ICP A constant 4mA bias current is available for ICP transducers that are used as signal input

for ZonicBook/618E’s analog channels (CH1 through CH8) and for compatible expansionmodules that accept ICP transducers, for example, the WBK18. The bias current is

sourced through the center conductor of the input channel BNC connector and returns tothe acquisition device [e.g., ZonicBook/618E or the WBK18] via the BNC’s outer

conductor.

The current source features an operating compliance of 24V and is protected in regard to

both short-circuit and overvoltage. Operating compliance refers to the highest voltagethat can be applied without change of the current source value. In the absence of a

transducer, the current source will output an open circuit voltage of 30V. For applications

that do not require bias, the current source can be disconnected from the input by un-checking ICP in the Input Channels tab on a per-channel basis.

When the ICP cell is checked for a channel, the current source is enabled, the input

voltage is continuously monitored with level detection circuitry. Recognition of a voltage

greater than 25V (transducer open) or less than 1V (transducer short) triggers a transducer

fault condition for the affected channel. This error is communicated to the user via a front panel LED and is also available through a software status request at the end of an

acquisition. When recognized, an error is latched until the commencement of a new

acquisition. Consequently, even intermittent faults are detected and communicated.Detection of a fault does not, however, alter the acquisition process or its data.

When the ICP function is not available to a channel a dash appears in the ICP column for

the associated channel.

Coupling AC or DC coupling can be set on an individual channel basis from the Input Channels tab

Coupling is available for analog channels (CH1 through CH8) and for compatible

expansion channels [e.g., from a WBK18]. AC Coupling can be set to a high pass filtervalue of 0.1 Hz or 1 Hz. The value is selected in the Edit Menu’s Acquisition Tab.

Note that when DC Coupling is selected the high pass filter is bypassed.

When the Coupling function is not available to a channel, or not used by a channel, a dashappears in that channel’s Coupling column.

Angle Loc is the physical angular location of a probe. Zero degrees is defined to be the top dead

center. The angle value is measured in the counterclockwise (CCW) direction as viewedfrom the driver end. Orbit and Polar displays utilize Instrument Angle for data correction

1xA Ref and1xP Ref

1x Amplitude Reference and 1x Phase Reference are the slow roll values used for Runout

Compensation on Bode or Polar displays.

Gap Volt is the DC voltage value when the shaft is at rest. This value is used for Shaft Center Line

displays.


34/94

XY Pair associates 2 probes on a bearing. Typically, probe pairs are located 90 degrees apart.Orbit displays require a Channel Pair.

Brg Clear Bearing Clearance is measured in the instrument’s engineering units. You can

optionally overlay the bearing clearance circle onto an orbit display or shaft centerline.

Brg Start Bearing Start is the location of the shaft relative to the bearing when the machine is at

mechanical rest. Three possible locations are taken into consideration: Bottom, Center,and Top. For horizontal shafts, a bearing start of bottom is typical, due to gravity;

However, in some situations mechanical linkage can result in a bearing start with the shaft

at the top. For shafts that are oriented vertically, a bearing start of center is likely.

DefaultTach

The "Default Tach" column allows you to define the Tach Preference for each channel.Thus, on Gauge Display and Plot Display eZ-TOMAS can show 1x values relative to the

preferred tach. When two or more tachs are defined eZ-TOMAS computes spectral data

relative to each. For example, with two tachs: If Tach 1 measures 3000 rpm and Tach 2measures 4500 rpm eZ-TOMAS computes 1xA values for each. With the RPMs given,

the resulting 1x Frequency values are 50 Hz for Tach 1 and 75 Hz for Tach2.

Clicking the Default Tach column brings up a pull-down list which indicates the

tachometer channels available for use as reference [for the currently displayed data].

Tach Section of the Input Channels Tab

Rotation is the shaft’s rotation direction, either clockwise or counter-clockwise. The direction

indicated is as viewed from the driver end of the machine train.

Trig/Rev is the number of pulses per 360 degree revolution. (Default: 1)

Trig Dir is the “negative’ [down arrow] or “positive” [up arrow] direction of the moving shaft.

Trig Volt defines the Tach pulse for tach signals. A keyway will generate a Negative Tach pulse.

Typical Tach signals will generate at least a 1 V pulse. You can check the voltage value

using a Time display.

Mode Used to select one of three available modes: Voltage, Counter, or Period.Edge Detect Edge Detect – Edge Detect is short for “Tach Pulse Edge Detection.” The term

pertains to detecting the rising or falling edge of a tachometer pulse using either an

“Immediate” or “Delayed” mode.

Immediate Edge Detection (“Before Stable”) – “Immediate” is one of two EdgeDetect modes. The term is synonymous with “Before Stable.” If “Immediate” edge

detection is selected a tach pulse will be recognized on any instantaneous measurement

that meets the trigger level criteria. In this setup the “Delay Value” is the amount of time

before the next tach pulse can be recognized. If a keyway is being used as a tach trigger

you must calculate the minimum pulse width, based on the maximum RPM rate

expected.Delayed Edge Detection (“After Stable”) – “Delayed” is one of two Edge Detect

modes. The term is synonymous with “After Stable.” If “Delayed” edge detection isselected a tach pulse will be recognized when the measurement meets the trigger criteria

for the specified duration. In this setup the “Delay Value” defines the length of time that

the trigger criteria must be stable before the tach pulse will be recognized.

Delay Time: One of several time settings between 500 ns and 25.5 ms. The delay time is used inconjunction with edge detect and is used to optimize noise reduction.

Tachometer Notes

To Assign a

Tachometer to a

Channel

1. Navigate in eZ-TOMAS as follows: Edit [pull-down men] \ SetupConfiguration \ Input Channels Tab \ Default Tach column.

2. Click in the Default Tach column and select the desired tachometer from the pull-down list.

To Assign

Tachometers to

the GaugeWindow View

1. Select “View” from the gage window’s tool bar.

2. From the resulting list, select the desired Tach, or select Default Tach. Notethat a Tach selection option will only be available if there are two or moretachometers to choose from.

If you select a Tach, for example, Tach 1 – that Tachometer will apply to all

applicable gauges, regardless of what tachometer is assigned to the channelin Setup Configuration.

If you select “Default Tach,” Tachometers will apply to the gauges inaccordance with the Setup Configuration assignments, as described in row 1

of this table, which describes how to assign a tachometer to a channel.

To Edit a

Tachometer

Channel’s

Parameters

1. Navigate in eZ-TOMAS as follows: Edit [pull-down menu] \ SetupConfiguration \ Input Channels tab.

2. Edit the parameters on a column by column basis, as desired. Note that thereare two places from which you can edit tachometer parameters:

(a) The main area of the Input Channels tab. This is where you can edit the

tachometer channel’s name, minimum and maximum gauge values, units,etc.

(b) The lower panel of the Input Channels tab. From here you can configure

the tachometer channel’s rotation (CW or CCW), trigger/revolution, triggerdirection (POS or NEG), and trigger voltage.

For applicable illustrations of the channel configuration areas, refer to the

preceding two figures.

To obtain optimalnoise rejection 1. Setup the input for Voltage Mode.2. Take a measurement.

3. View the Tach Signal on a TimeWaveform plot.

4. Set the Trigger Slope [Trig Slope] to Positive (POS) or Negative (NEG).

5. Set Edge Detect to “Immediate” or “Delayed.” You may need to experimenwith Edge Detect settings to determine whether “Immediate” or “Delayed”

works best for your application. Optimum settings will vary from machine

to machine.

6. Set the Delay Time to a pre-set value between 500 ns and 25.5 ms. To haveno delay time select “none.”

Synopsis o f Tach Modes

When you connect a tach sensor to a tachometer designated connector, such as the ZonicBook/618E’s

TACH BNCs (TACH1, TACH2, TACH3, or TACH4) you can select one of the following three modes:

Counter, Period, or Voltage. If you connect a tachometer sensor to a direct Analog Signal Input channel

(CH1 through CH8) then the tachometer signal will only be accepted in the Voltage Mode.

If tachometer triggers will occur at a rate greater than or equal to the “scan rate

divided by 10” then the Period Mode must be used.

Counter Mode

Use Counter Mode when Pulses perRevolution are needed.

Counter Mode can be used for phaseshift observance.

Counter Mode generates a Pulse of Amplitude “+1” for each tachtrigger. The counter mode can be used when the number of

pulses is less than the scan rate divided by ten (< scan rate / 10).

Once you have established the phase relationship of a machine

running near optimum, the observance of phase shifts can be

used to signal the development of a mechanical problem.

Period Mode

Use Period Mode when multiplepulses are involved, such as fromgear teeth.

Period Mode cannot be used forphase shift observance.

The period is the time from the rising edge of one pulse to the

rising edge of the next pulse, or the time from the falling edge of

one pulse to the falling edge of the next pulse.

The Period Mode is used for Tachometer inputs which exhibitmultiple pulses per revolution. The mode provides accurate

overall RPM without sacrificing scan rate. Phase measurements

are not possible when using period mode.

Note: 60 seconds divided by the period [in seconds] equals RPM.

Voltage Mode

Use Voltage Mode when you need todetermine a trigger voltage.

Voltage Mode is used for Tachometer inputs to view actual input

voltages from the Tach Sensor. Voltage mode is useful forlocating an ideal Tach Trigger Voltage setting. An ideal trigger

voltage is one that is in a clean region of a leading edge. Note

that Voltage Mode cannot be used for Phase measurements between Analog Inputs and Tachometer Inputs.

If you connect a tachometer sensor to one of the 8 Analog Signal

Input channels (CH1 through CH8) instead of a TACH channel,

then the tachometer signal will only be accepted in the Voltage

Mode.



37/94

Spectral Bands Tab

Up to 10 Spectral Bands can be selected for each dynamic channel. The bands named Overall, DC Gap V,1x Amplitude and 1x Phase are pre-defined and cannot be modified. However, you can modify “User

Defined” bands 5 through 10, customizing them for your specific application.

Spectral Band values are displayed on the dynamic instrument gauges on the eZ-TOMAS main window.

All gauges are vertical, with exception of circular phase gauges. When “1x Amplitude or 1x Phase is

selected both a vertical gauge [for 1x Amplitude] and circular phase gauge [for 1x Phase] are displayed.

Spectral Bands Tab

Default Tach Refers to the tach channels being used in the project. You must select the tach of

interest.

Channel Name is the name you assigned to the input channel in the Channels Panel.

Band is the Spectral Band Number of interest. Only the “User Defined” bands

[5 through 10] can be modified.

Spectral Band is the name you assign to a spectral band. It is displayed on the dynamic instrument

gauge in the main window.

Freq Units can be either Frequency or Orders. If you do not have a tach defined, the Orders

option will not be available.

Freq LO Freq HI

Used to set the range of the frequency or order. It is a good practice to set the range2 to 4 spectral lines wider than the frequency of interest. This is due to the FFT

window. For example, if your frequency of interest is the 3rd order. You shouldspecify a range of 2.9 to 3.1 orders

CALC Specifies to calculate Peak, Overall, or Phase.

Peak is the highest spectral amplitude within the specified range.Overall is the sum of vibrations of each spectral amplitude within the specified range.

Phase is the time relationship between the vibration probe and tach signal.

Amp LO

Amp HI

Used to set the low and high amplitudes. These high and low values define the gauge

range.

Storage Tab

Storage Tab

Basic Description

Data storage is activated by trigger events. If any one event is triggered, data from all channels is stored.

Data storage events are triggered when a change occurs within the range of your defined parameters. An

example follows the parameter definitions.

Panel Description

History FIFO Displays the number of storage records in the History FIFO (First-In-First-Out) file.Based on the configuration, values for both the required and the available disk space

are shown. The panel includes a checkbox to enable backing up the project.

RPM Range The range in which a specified RPM change and/or time change must occur to trigger

data storage.RPM Change An RPM-based trigger for the storage of data. Data will be stored when the machine

speed changes by the specified RPM value. To enable the delta RPM storage trigger

check the “Enabled” checkbox and enter an RPM value.

Time Change A time-based trigger for the storage of data. Enter the number of seconds, minutes,

hours, or days between desired storage events. To enable the time-based triggercheck the “Enabled” checkbox.

Overall Change An amplitude-based trigger that can be defined for each channel. Data is stored whenthe overall amplitude changes by the specified value. The user must check the

“Enabled” box for each channel that is to be used as an overall change trigger.

User Snapshot Used to specify the duration of continuous data gathering (in seconds) for a datasnapshot. When the snapshot button is clicked [the button with the camera image],

data will be collected for the specified duration.

The history file is a FIFO file. You can define the depth of the history file; however, the amount of time

needed to fill the file depends on the trigger event values. The smaller the trigger values, the faster thehistory file fills. The current data storage status is shown in the Main Window.



39/94

Example

Assume that a motor typically runs at 3600 RPM and we would like to store data when the motor is running

above 200 RPM and below 5000 RPM.

1. Open the Edit menu.

2. Select “Setup.” The Setup Configuration window will open.

3. Select “Storage Tab.”

4. For RPM Range enter a value of 5000 for the maximum and 200 for the minimum.

5. Set one or more of the following to trigger data storage:a) Time Change

b) RPM Change

c) Overall Change (the overall change in engineering units)

For this example assume that Time Change and RPM Change were both set to “None” and the

Overall Change trigger for a channel was set to set to 0.25 mils.

6. Click .

With this configuration, data will be stored if . . . the motor’s speed is greater than 200 RPM and less

than 5000 RPM and the overall value changes by 0.25 mils [since the last trigger event]. In this case

eZ-TOMAS will store time waveform and spectral gauge (band) data for all channels. All event triggers

are reset whenever any event trigger occurs.

In other words:

IF minRPM < Motor Speed < maxRPM

AND IF {delta Time, OR delta Speed, OR delta EU = specified setting}THEN data is stored.



40/94

Limits

The Limits Configuration window is accessed from the Edit pull-downmenu. The window provides the user with a means of setting limits and

ranges via three main scenarios. These involve setting:

Default Spectral Limits [without RPM ranges]

(used for Acquisitions, or in Post Acquisition for reports) •

•

•

RPM Alarm Ranges and RPM Alarm Limits

(used for Acquisitions, or in Post Acquisition for reports) Selecting Limits from the Edit Pull-down MenuExcel Report Ranges and Delayed Limits

( Only used in Post Acquisition for reports)

The type of configuration is determined by radio button selection, as can be seen in the following pages.

Up to two High (HI and HI-HI) and two Low (LO and LO-LO) limits can be defined for each channel’s

operating condition. The graph colors are defined in the Display Preferences window. If the channel

value is lower than the LO-LO limit, the bar graph will change to the color indicated in the LO-LO columnheader (see following figure). A value between LO-LO and LO limits will cause the bar graph color to

change to the specified LO limit color. HI and HI-HI limits have the same effect, relative to channel value.

A bar will be green for normal channel values (those between the LO and Hi limits.

Addi tional Limit Configurat ion Aspects

When a limit value is set to zero, the limit setting is turned off.

In the Limits dialog you can choose to ignore the RPM limits feature by clicking the Use Defaults Spectral

Limits option (see upper screen shot on next page), or you can click the Use Spectral Limits with RPM Ranges option and define an additional set of limits for each desired RPM range.

Settings pertaining to the “Set Excel Report Ranges and Delayed Limits” have no effect on an acquisition.These settings only apply to Excel reports. Chapter 6 provides details.

The following pages pertain to the following three bulleted scenarios:

Default Spectral Limits [without RPM ranges](used for Acquisitions, or in Post Acquisition for reports) •

•

•

RPM Alarm Ranges and RPM Alarm Limits

(used for Acquisitions, or in Post Acquisition for reports)

Excel Report Ranges and Delayed Limits

( Only used in Post Acquisition for reports)

Each section shows the Limit Configurations window with the appropriate radio button selection. In eachcase a flow diagram is provided to allow the user to visualize the key configuration elements. Comparing

the three methods to each other will improve your understanding of the Limit Configuration windows

functionality.In each of the following cases, a spreadsheet representation of Spectral Band limits is visible for only 1

input channel at a time. Note that a given channel can have several different sets of spectral limits and

delays. For example, a different set for each tachometer; and when ranges are used, a different set of limitscan for each of 5 possible ranges and for each of up to 3 tachometers.

Although Excel Report Ranges and Delays are set in the Limit Configurations window, it is from the XL

Report window (discussed in chapter 6) that the setting options are selected for the report. Please refer tothat chapter for details.


42/94

Using Default Spectral Limits [RPM Ranges not used]

Note: In the above figure “Tach Channel(s) Tach Ref” is the same as “Default Tach.”



43/94

If the RPM Range option is selected [following figure] you can define up to 5 non-overlapping RPM

ranges. There can be gaps in the user defined RPM ranges; however, the ranges may not overlap. For

example: Range 1 can be assigned to cover 400 to 800 RPM, and Range 2 can be set to cover 900 to 1000RPM - ignoring speeds between 800 to 900 RPM. But you can't set Range 2 to cover 700 to 1000 RPM,

as that overlaps the coverage in Range 1.

When RPM ranges are used, there is a unique set of limit set-points for each combination of: Tach

Channel, Input Channel, Range, and Spectral Band. For convenience, you may copy and paste limit

settings between Channels.

Limit values are not used if:(a) the ‘HiHi limit value’ minus the ‘LoLo limit value’ is less than 5% of the

instrument scale, or

(b) the limit value is outside of the instrument range.

(c) the limit value is set to Zero.

Limits from one channel can be copied to another from the Limit Configuration

Window’s Edit pull-down menu, using the “Copy Channel” option, or by selecting

multiple channels.

Tach You may have up to three tachs per project.

Select the Default Tach for the limits.

Channel Number of interest. Select the channel(s) of interest.

Spectral Band To which the limits should be applied. ( i.e. Overall, DC Gap, 1x Amp,

1x Phase)

HIHI, HI, LO, LOLO Are Limits. Up to two High and two Low limits can be defined for each

channel’s operating condition. Limit values are typed (entered) into theapplicable rows and columns. See previous figure.

You can modify limits on the graphical bar graph display in the main window by

dragging the limit arrows and then opening this window to save your changes. You may

also right-click on a limit arrow to open the Limit's configuration dialog box. Note that

right-clicking elsewhere on the bar will bring up the Setup Configuration Window.

FIFO Records Is the number of Alarm events logged. When an alarm occurs, eZ-TOMASautomatically saves the data to the History FIFO file.

RPM Range The RPM range as defined by the minimum and maximum RPM values of thelimit check. This RPM Range is the limit check range.

An Example of Using Limit Ranges

With exception of speed change transients, an experimental induction fan was designed to run at one of three normal

operating speeds: 2,500 RPM at low speed; 7,500 RPM at medium speed, and 12,500 RPM at high speed. Anengineer wants to run limit checks for the medium and high speeds. More specifically, he wants to check Channel 2

for a range of 5,001 to 10,000 RPM; and Channel 3 for a range of 10,001 to 15,000 RPM. Thus, he performs the

following steps:

1. Opens the Edit menu.

2. Selects “Limits.” The Limit Configuration window opens.

3. In the Limit Configuration window he:o Selects the Use Spectral Limits with RPM Ranges option.

o Checks Channel 2 and Channel 3 to “ON.” (See following figure, upper screen image).

o Sets the limit check range for Channel 2 as follows: Min. RPM to 5,001; Max RPM to 10,000.

o Sets the limit check range for Channel 3 as follows: Min RPM to 10,001; Max RPM to 15,000.

o Un-checks all remaining channels to turn them “Off.”

o Clicks .

Note that the following figure reflects these settings.

The panel below the Digital I/O Panel will be an Alarm Event panel for Digital Output channels, as indicated in theleft-hand image; and will be an Action Performed panel for Digital Input channels, as indicated in the right-handimage.

Digital I/O Channels Panel

The second panel of the Digital I/O Configuration window is the Digital I/O Channels panel. There are

four Digital I/O channels, each of which can be configured for digital input or digital output. As seen in the

above figure [which shows a Digital Output example on the left and a Digital Input example on the right].

Each of the 4 channels has a Checkbox that is used to enable or disable the digital I/O function of the

channel. A checkmark in the box indicates that the channel is active.

The “DI / DO” column is used to select Digital Input or Digital Output. Clicking on the small

schematic icon (in the column) toggles between the two options, i.e., Input and Output and displays an

associated image. The arrow going into a connector represents Digital Input, the arrow leaving the

connector represents Digital Output.

The “NO / NC” column refers to the normal state of the Digital Output. The normal state can be set to

be Normally Opened or Normally Closed on limit/alarm status. You can use up to four relays. A blue

line, showing an open between two points is used for Normally Open. A red line, connecting two

points, is used for Normally Closed.

• The DO Timer column refers to the time [in seconds] that the Digital Output is to be active. The DOTimer box will display “n/a” when Digital I/O is selected.

Alarm Events Panel (Digital Output Only)

The color of the response channel in the “Alarm Events” panel indicates the limit/alarm status that willcause the switch to change status, i.e., from Opened to Closed, or visa versa. Click on a channel number

until the desired limit color is displayed. If the relay is normally Opened when monitored data causes the

specified limit/alarm, the relay will change to Closed for the duration specified by the timer; then it willreturn to the normally Opened status.

Note that you can have the system count the number of consecutive alarms and change the relay statuswhen that number of alarms is reached.

Action Performed Panel (Digi tal Input Only)

This panel consists of a pull-down list that allows you to select one of several “actions” for Digital Input

applications.

Possible actions are:

• Store Snapshot

• Change Acquisition State• Change Limit Check State

• Increment Serial Number

• Increment Serial Number and Reset Peak Hold

When you click the Save button, any of the unchecked check boxes for relay channels

will close and stay closed until the condition is met for that relay channel. If you have

something that will actuate when the channel closes, it will do so as soon as you click the

Save button.

Display Preferences Window [in Edit Menu]

Display Preferences Window

The Display Preferences Window provides a means of changing various display colors and other

parameters, including, but not limited to, Waterfall latitude and longitude angles, and units for thefrequency axis. If a machine name is entered (upper-right text field), it will appear on the eZ-TOMAS

main window, in the Machine Description region.

Although most display preference functionality is self-explanatory, the following information may be

useful to some.

The Gauge Window Colors panel allows you to define the colors seen on themain EZ-TOMAS window. Gauge refers to the background color of the

Analog Input Channel gauges. Tach is specific to the Tach Input Channelson the ZonicBook/618E.

The Machine Information panel consists of a textbox for displaying the

machine name, serial number, of some other identifying information.

The Plot Window Colors panel allows you to define the Plot Display's

border, background, and grid colors.

The Display Buffer panel consists of a single numeric field for indicatingthe Realtime Trend. This value defines the amount time [in minutes] that

data will be displayed before scrolling will begin. For example, if theRealtime Trend was set for 2 minutes the trend display would show the data

being collected for two minutes, and then start scrolling after 2 minutes. In

this example the screen will always display the most recent 2 minutes of

data.



49/94

Display Preferences (continued)

The Plot Trace Colors panel allows you to define colors for use

in the plot displays. If you select "By Trace" the sequentialorder of the Trace Number will define the plot color. If you

select "By Channel" colors will be assigned to specific

channels according to the numbered color squares (see figureat left).

The Alarms panel defines alarm colors for the Gauge and Plot displays. The

panel includes two numeric fields. The upper field indicates the number of

records to be displayed. The lower field, for Pre/Post Alarm Event, definesthe amount of data that will be displayed when using the Alarm Log report.

The Waterfall Display panel is limited to a fixed number of spectrum traces,

up to 100 traces. The Longitude Angle defines the vertical tilt of the display.

The Latitude Angle defines the horizontal tilt.

The Frequency Axis panel is used to set the frequency axis to Hz or CPM.

Select Hz-Orders for cycles per second ; or select CPM-Orders for cycles

per minute.

The Bode Display panel allows for selecting “Unwrap Phase” by means of acheckbox. When the box is unchecked the phase plot will be "Wrapped."

Wrapped means the Y-axis scale is 0 to 360 degrees. Data that straddles the

0 / 360 boundary will show a vertical line.

Unwrapped allows the Y-axis scale to span multiple 360 degrees. When

“Unwrap Phase” is selected data will smoothly transition across the 0 / 360 boundary.

The Main Cursor and Harmonic Cursors can be shown with or without a

vertical line. Click on the first button [in the associated cursor panel, left

figure] to toggle to the desired choice (line or no line). The second button in

each panel allows you to choose a color for the associated cursor.

The Orbit Display - Bearing Circle panel allows the user to select “ProbeLocation” or “X / Y Axis.” The selection defines the Bearing Circle on the

Orbit display. If the bearing clearance is elliptical, select the locations that

will be used to measure the clearance.

Copy Window

“Copy Window” is not a window, but a command to copy the currently selected window to the clipboard.

After using this command you can paste the copied window into another application, such as Microsoft

Word or Excel. The feature is useful for creating reports, or sending screen images to others via e-mail.

Load [or Remove] Graphic Picture

The Load command places a selected graphic ( .bmp or .jpg format) into the Machine Description Window.

The Remove command removes it.

An alternative to using the command is to right-click in the graphic region. You can then load the desired

graphic file. Right-clicking in this region also provides you with the option of removing an existing

graphic.

The title bar text is entered in the Display Preferences Window (accessed via the Edit pull-down menu.

The lower text field information is entered directly into the field.

Reset Peak Hold Values

Momentarily resets the peak values. However, the new peak acquisition values [which exist from the point

of reset] will immediately apply.

Introduction

The Display pull-down menu [following figure] provides a means of displaying plots and several types of

logs, or reports. This chapter covers the Plots aspect. Chapter 6 pertains to the various logs (reports) that

can be generated from the menu.

Select Plots from the Display Pull-down Menu

Selecting Plots from the Display pull-down menu opens a Data Display window. Note that you candouble-click on a gauge to open a Data Display window for plotting that gauge’s data.

For real-time displays, you can halt and resume the display of data by using the Pause/Continue toggle button, or use the “P” key on the keyboard. When viewing historical data, you can use the five playback

buttons and the slider to navigate through the data (see the following figure).

You can view either real-time data or historical data. In the examples that follow we are view historicaldata, thus the History button has been clicked, and appears “active” [green] on our screen.

Prior to viewing a plot you need to:

select the channels to be displayed•

Changing Display Ranges and ScalesTo change the maximum or minimum range value (following figure): Left-click on

upper or lower scale value that is to be changed, then enter the new value. An example follows. This technique works for

both X and Y axis.

In this example, the cursor and PC

keyboard were used to change the

maximum scale value from 3.000 volts

to 3.800 volts.

To change the X-Axis (following figures): Hold down the key, at the same time, left-click and drag the mousecursor horizontally on the plot. Two vertical cursor lines will define the new x-axis end points.

To change the Y-Axis (following figures): Hold down the key, at the same time, left-click and drag the mouse

cursor vertically on the plot. Two horizontal cursor lines will define the new Y-axis end-points.

To simultaneously change the X & Y Axes (following figures): Hold down the and keys, at the same time,left-click and drag the mouse cursor diagonally on the plot. A rectangle will define the new area of the plot.
