What is eZ-TOMAS?

eZ-TOMAS (Total Online Monitoring and Analysis Software) is designed to collect vibration and process
data 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 to
three 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.

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 real­time 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 the
toggle 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 depicted
on 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” are
simultaneously 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.

eZ-TOMAS 987294 Introduction 1-5

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 acquired
data 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 self­descriptive 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/O

toggle switch.

4) Save Snapshot – A data storage trigger that can be used instead of the “camera” button. The

duration 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.

1-6 Introduction 987294 eZ-TOMAS

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 Overall
value 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.

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 <Snap Shot> (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 Data
File Date Range.

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

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 the
machine, 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 acqu isition switch, data will be
appended to the data files.

eZ-TOMAS 987294 Monitoring a Machine 2-1

Using “Initialize Project”

If you have multiple hardware modules, and change the number of Input Channels, you
need to use the initialize function to create a new eZ-TOMAS Project. This needs to be
done once, for the first implementation of the new hardware setup. An explanation of
how to access and use the Initialize Project function follows.

When a project is initialized you are essentially starting with a “clean slate.” No data is
carried over, as would be when a project is cloned as discussed on page 2-4.

“Initialize Project” is accessed from the File pull-down menu. Initialize Project provides a means of
selecting the hardware device and setting the number of input channels. For example: If you had an 8
channel Medallion and were going to change your acquisition to 24 channels, for example, using a
ZonicBook/618E and two WBK18 modules, you would need to use the Initialize Project feature.

Complete the following steps to initialize a project. Note that the step numbers correspond to the numbers
in the figure.

1. From the File pull-down menu, open “Initialize Project.” An Initialize Project dialog will open.

2. Select the Hardware Device from the associated pull-down list.

3. Select the number of analog input channels from the associated pull-down list. For
ZonicBook/618E do not count the separate tach channels as input channels.

4. If applicable, enter and confirm the project password.

5. Click the <OK> button.

Staying with our 24 channel example [using a ZonicBook/618E and two WBK18 modules], the gauge panel
will now appear with three rows of data beneath the gauges (see following figure). Each row will have 8
data cells (one per input channel). Note that the gauge panel can display up to 7 rows of data, thus
accomodating 56 channels.

Only 8 gauges can be displayed at a time, but the cells allow you to choose which gauges to view, as will

be seen in the following three figures and related text.
Note: For greater clarity in the following three figures, gauges have been compressed vertically and several

gauges have been removed, e.g., channels 5, 6, an d 7 fo r Fi g 1; cha n nel s 1 3, 1 4, an d 15 for Fig . 2; and
channels 21, 22, and 23 for Fig. 3.

2-2 Monitoring a Machine 987294 eZ-TOMAS

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

In Fig. 1 we see that Accel Ch 1 through Accel Ch 8 are being display e d. Chan nel s 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 displays
data for channels 9 through 16, and the third row displays data f or 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 the
channel 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 3

Note “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 chan nels 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 to
have 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.

eZ-TOMAS 987294 Monitoring a Machine 2-3

Using “New (Clone) Project”

Cloning a project keeps all of the values from the original project.

Each eZ-TOMAS Project contains eZ-TOMAS configuration and data files. You should logically equate
an eZ-TOMAS Project with a specific machine. This is accomplished as follows:

1. On the File pull-down menu, select New (Clone) Project. This opens the Save As window.

Save As Window, Being Used to Create a New File

2. Select [or create] a Windows folder for the eZ-TOMAS Project.

3. Enter the desired filename for this project.

4. Click the <Save> button to create the new project.

2-4 Monitoring a Machine 987294 eZ-TOMAS

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 <Cancel> 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 <Save> button.

You can start monitoring immediatel y .

Acquisition Tab – From the Acquisition tab you can set up parameters that include, but are not limited

to: 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. This

includes, but is not limited to assigning channel types, customizing channel names, settin g the instrument
range per channel, and assigning units.

Spectral Bands Tab – From the Spectral Bands Tab you can modify “User Defined” bands 5 through

10 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 one

event 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 Chan ge.

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

eZ-TOMAS 987294 Monitoring a Machine 2-5

Starting an Acquisition

After you configure your eZ-TOMAS Project, click the <Acquisition> 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 for
that 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 or

Tile 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.

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 by
channel. 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 the
alarm signal.

Display Pull-down Menu

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 <Snapshot>

Acquisition Tab

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

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,

dB Reference

Acquisition

or Medallion.

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 input
channel types. The default setting is 20 micro-Pascals (0.000020 pa).

Analysis Frequency (Hz) The maximum frequency of interest. The
sampling 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 maximum
rotating speed. Typically, this multiple is at least 10 times the rotating
frequency.

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

Overlap Data Acquisition For slow speed data acquisition
applications, you have the option to select overlap data processing to
speed 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 automatically
determine the overlap percentage needed to achieve a 1 to 2 second
display update rate. For example, if your analysis frequency is
500 Hz and you have 3200 spectral lines, the acquisition time is 6.4
seconds. With Overlap Data Acquisition, the overlap percentage will
be 75% and the update rate will be 1.6 seconds. (6.4 sec / 4). The
divisor is a power of 2.

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

FFT Window Fast Fourier Transform. FFT is an efficient technique
for calculating the frequency of components in a time-domain
waveform based on digitized voltage measurements. The result is a
display of amplitude versus frequency and phase versus frequenc y.
The FFT Window is a weighting window, typically either H anning or
Flat Top. Hanning provides better frequency resolution. Flat Top
provides better amplitude resolution.

High Pass Coupling Filter (Hz)

High Pass Filter (AC Coupling): When AC Coupling is selected in

the Input Channels tab, the associated input signals will pass through
a 0.1 Hz or a 1 Hz High Pass Filter, depending on which radio button
is selected.

High Pass Display Filter (Hz)

Allows you to eliminate the lower frequencies from the full frequency
range for “no,” “single,” and “double” integrations by entering the
desired cutoff value in Hz. All data points that exist below the
specified 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).

Terms and factors related to the Acquisition Panel

Nyquist Factor

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

Sampling Rate

Spectral
Resolution

A rate that is 2.56 times the Analysis Frequency. If the Analysis Frequency was
1000 Hz and if the Spectral Lines was 800 lines; then the Sampling Rate would be
2560 samples per second. This rate would apply to each channel. Derived from:
Analysis Frequency x 2.56 = 1000 x 2.56 = 2560.

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

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

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 are
unsure 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 expansion
modules 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 to
the 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 voltage
that 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 un­checking 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 filter
value of 0.1 Hz or 1 Hz. The value is selected in the Edit Menu’s Acquis i t i on 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 channe l, a dash
appears in that channel’s Coupling column.

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.

Default
Tach

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 2
measures 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].

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

Mode
Edge Detect

Used to select one of three available modes: Voltage, Counter, or Period.

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 Edge

Detect 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 Stabl e”) – “Delayed” is one of two Edge Detect

modes. The term is synonymous with “After Stable.” If “Delayed” edge detection is
selected 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 in
conjunction with edge detect and is used to optimize noise reduction.

Synopsis of 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

Counter Mode generates a Pulse of Amplitude “+1” for each tach
trigger. The counter mode can be used when the number of
pulses is less than the scan rate divided by ten (< scan rate / 10).

Use Counter Mode when Pulses per
Revolution are needed.

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.

Counter Mode can be used for phase
shift observance.

Period Mode

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 exhibit

Use Period Mode when multiple
pulses are involved, such as from
gear teeth.

Period Mode cannot be used for
phase shift observance.

multiple 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

Voltage Mode is used for Tachometer inputs to view actual input
voltages from the Tach Sensor. Voltage mode is useful for
locating 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

1x Amplitude and 1x Phase are pre-defined and cannot be modified. However, you can modify “User

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.

Storage Tab

Panel Description
History FIFO

RPM Range

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.

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 trigger
check the “Enabled” checkbox.

Overall Change

An amplitude-based trigger that can be defined for each channel. Data is stored when
the 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 data
snapshot. 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 the
history file fills. The current data storage status is shown in the Main Window.

4-10 Edit Menu 947394 eZ-TOMAS

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 <OK>.

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.

phase gauge to bring up
the Limit Configuration
Window.

“Left-Click and Hold” on a

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 each
case 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 limits
can 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 to
that chapter for details.

Using Default Spectral Limits [RPM Ranges not used]

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

4-14 Edit Menu 947394 eZ-TOMAS

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 1000
RPM - 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
Spectral Band

Number of interest. Select the channel(s) of interest.
To which the limits should be applied. ( i.e. Ove rall , DC Ga p, 1 x 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 the
applicable 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-TOMAS
automatically saves the data to the History FIFO file.

RPM Range

The RPM range as defined by the minimum and maximum RPM values of the
limit 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. An
engineer 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 follo ws: Min. RPM to 5,001; Max RPM to 10,000.
o Sets the limit check range for Chann e l 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 <OK>.

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 the
left-hand image; and will be an Action Performed panel for Digital Input channels, as indicated in the right-hand
image.

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.

4-18 Edit Menu 947394 eZ-TOMAS

• The DO Timer column refers to the time [in seconds] that the Digital Outp ut is to be active. The DO

Timer 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 will
cause 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 will
return to the normally Opened status.

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

Action Performed Panel (Digital 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 the
frequency 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 the
main EZ-TOMAS window. Gauge refers to the background color of th e
Analog Input Channel gauges. Tach is specific to the Tach Input Channels
on 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 indicating
the Realtime Trend. This value defines the amount time [in minutes] that
data will be displayed before scrolling will begin. For example, if the
Realtime 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.

4-20 Edit Menu 947394 eZ-TOMAS

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 sequential
order 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 figure
at 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, defines
the 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 a
checkbox. 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 de grees. 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 “Probe
Location” 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.

Scale – Toggles between Instrument Scale, Auto Scale, and User Scale. User Scale is shown in the figure.

Instrument Scale is the default. It displays the data based on the instrument’s Engineering Units range.

Auto Scale automatically scales the axes based on the data being displayed.

User Scale is used to display data in relation to a user-defined scale. You can quickly customize a scale as

follows:

(1) press the <Ctrl> + <Alt> keys and hold them in.
(2) press the <left mouse button> and hold in
(3) move the mouse cursor to draw a rectangle around the area of the plot that you desire to view.
(4) release the mouse button and the two keys. Your plot should now have a new and more practical

Delta Time or Delta Record – For Stripcharts Only: Selects one of two X-axis spacing types.
(a) When button (7) is gray, Delta Time is selected for the X-Axis. Delta Time spacing displays data with

absolute time for the X-axis.
(b) When button (7) is green, Delta Record is selected for the X-Axis. Delta Record has X-axis time

spacing based on record changes. Thus the time line on the X-axis is not uniform. Delta Record spacing is
good when there are short acquisition durations over long periods of time as vacant time slots are
eliminated from the display.

Skip Records or Use All Records – For Waterfalls Only: Selects one of two display modes.
(a) When button (7) is gray, “use all Records” is selected and the entire Waterfall will scroll. Scrolling can

be forward or backward.
(b) When button (7) is green a maximum of 100 records will be scrolled based on a Skip Record Factor.

SRF = History Records / Waterfall Records - 1. Thus if we had 634 history records and 100 waterfall
records we would have a skip factor of 6.4 records, i.e., 634 / 100-1 = 6.4 records. This skip factor would
result in 100 records being scrolled. Note that the SRF is automatically calculated and applied by software.

the Display Cursor Values button is activated. (see Display Cursor Values). Note that the “L” key on the keyboard can be

used to display the gauge values.
Cursor Update - Fixed X axis / Peak Search – When this button has a gray background, the x-axis is fixed and the
cursor will not move when a new spectrum is plotted. When the button has a green background “Peak Search” is in effect
and the cursor will automatically move to the highest point on the plot. The button is typically used for Spectrum plots,
either Real Time or Historical Data.

Cursor Mode – Only available for Spectrum plot displays. The button cycles through the following four modes.

Normal (gauge values) – A free-moving single cursor provides a point for each trace displayed. This is the
only cursor that can be used with multiple traces.

Harmonic – Can only be used when 1 trace is displayed. Results in several cursors positioned to the right of

the primary cursor and at intervals that are at twice the x-axis value of the primary cursor. For example: When
the primary cursor is at 100 Hz, the first harmonic cursor will be at 200 Hz, the second at 400 Hz, the third at
600 Hz, etc. Moving the primary cursor to 400 Hz would result in the first harmonic cursor residing at 800 Hz,
the second at 1200 Hz, etc. If Display Gauge Values is selected, the applicable values will be shown for all
cursors. Harmonic cursors can only be moved by moving the primary cursor.

Side Band – Can only be used when 1 trace is displayed. Results in several cursors spaced at even intervals
on both sides of the primary cursor. Unlike the harmonic cursors, the sideband cursors can be moved by the
user. Once adjusted, they remain in position at until the next adjustment. If Display Gauge Values is selected,
the applicable values will be shown for all cursors.

Peak List – Can only be used when 1 trace is displayed. On a real-time or playing plot, the cursor will
automatically position itself at the highest point on the trace.

Overlay Limits – For Spectrum, Stripchart, and Polar plot windows. Superimposes the limit values onto the displayed
data.

Runout Compensation – displays a graph of the RunOut compensated values. RunOut compensation is a vector math
operation in which the referenced first-order amplitude and phase vector is subtracted from the displayed first order
vector. This option is only available for Bode and Polar plots.

Overlay Bearing Clearance Circle – Superimposes the bearing clearance circle over the plot display. This feature can
be used with the following plot types: Orbit, Shaft Centerline, Bode, Stripchart, and Time Waveform.

Band Pass Filter Selection – Used with Time and Orbit plots. Allows the user to apply an nX filter to time data for Time
and Orbit plot displays.

Shaft Revolution Filter – Used with Time and Orbit plots. This filter selection is used to limit the amount of data
displayed. The limitation is set by selecting “n,” where “n” is equal to the number of shaft revolutions. The Shaft
Revolution Filter is used to make the plot display cleaner by reducing clutter from excess data.

Orbit Displays show simultaneous time domain vibration amplitud e for an X and Y probe pair.
The location of each Tach pulse is shown on the orbit plot using black circles; and a rotation direction label

("CCW" or "CW") is shown next to these (see figure).
The default display is “Full Block” of time data. However, a specific number of Shaft Revolutions can be

displayed (1, 2, 5, or 10) by using the associated pull-down list (see figure). The orbit display is corrected
for probe location.

You can optionally overlay the orbit onto a shaft center line display by clicking the Shaft Centerline
button. The center of the orbit trace in SCL computes the difference between the current gap voltage and
the reference gap voltage. Information regarding shaft centerline plots is presented on page 7-9.

Shaft Center Line (SCL)

Shaft Centerline (SCL) is used to display the change in gap voltage for a Channel Pair. SCL is typically
used in conjunction with Displacement Probes.

In order to get valid SCL displays the input channels must be DC coupled.

The measured DC Gap Voltage is corrected to the Gap Reference Value and Shaft Starting Location
(Brg Start), which are set in the Edit pull-down menu’s Setup Configuration window, in the Input
Channels tab.

With options to “Save the Report” and to “Generate Limits”

Statistical reports can be used to automatically generate limit values based on historical data. If your
monitored machine has been operating at a steady state condition and if you have stored data at this
condition, then eZ-TOMAS can use this data to determine limit values based on the average and variance
of the data. However, you probably will want to edit these limits if the machine is experiencing amplitude
or frequency shifts.

8-6 Display Menu…. Reports 947494 eZ-TOMAS

Reports are created using the option settings that are defined in the project. Among the options available
you have your choice to include:

• Specific channels.

• Specific Spectral Bands.

• Choice of Reference Tach.

• Starting and Ending data block range.

• The Maximum, Minimum or Average data value associated with a specific Spectral Band.

• Inclusion of the Limits settings in the report and the selection of which limits to include.

• A Pass/Fail indication. A Pass condition exists if the Spectral Band data never exceeds the

selected limit(s).

• Machine and operator information, and a project comment.

• Report formatting option.

• Speed Ranges. You can choose one of five options via radio button (see following figure). A

brief description of each follows shortly.

Speed Range Options

Note that the Limits Configuration dialog (discussed in chapter 4) allows you to configure two
sets of Ranges [and their associated Range Limits] in addition to the range independent Default
Limits. One set of Ranges and Limits are for the Alarms. The alarm settings are used during your
monitoring session and provide range sensitive limits that, if exceeded, will cause an alarm
condition. The other set of Ranges and Limits have no bearing on the data acquisition and are
used by the Microsoft Excel report generator in post -acq ui sition.

When you run your Excel report, the five different Speed Range options are as follows. The
Limits section of chapter 4 includes information pertaining to the actual setting of limits.

Default Limits. Selects the default limits. These are range independent. When this option is

1.
selected all of the data [for each selected channel and gage] is compared against the default
limits.

against this set of ranges & limits. Up to 5 ranges can be selected from the resulting range list
(see following figure). The ranges are set in the Limits Configuration dialog, discussed in
chapter 4.

RPM Ranges

eZ-TOMAS 947494 Display Menu …. Reports 8-7

Report RPM Ranges. All of the data for each selected channel & gage is compared against

this set of ranges & limits. Up to 5 ranges can be selected from the resulting range list which will

ranges are set in the Limits Configuration dialog box, discussed in chapter 4. Note that the Range
dependant delay values [set in Limits Configuration (reference chapter 4)] are ignored.

> (Greater Than) Report Limits Delay. This selection uses the Report Ranges and Limits.

4.
When “> Report Limits Delay” is selected the report generator only examines the data beyond the
specified delay time, added to the first data record that was detected within a specific RPM range.

For example: If data record number 100 was the first record that was stored when the turbine
RPM was in the range of 85,000 to 100,000 RPM, and data records were being saved at a constant
rate of 1 per second, and the specified delay value of 1.0 minute was given, then the first record
that will be used in the report will be record number 160. All further records acquired in the
85,000 to 100,000 RPM range will also be used in the calculations for Minimum, Average, or
Maximum values compared against the selected Report limit values. Note, however, if the
turbine should slow down enough that a range change is detected, and then speed back up to the
85,000 to 100,000 RPM range, another delay time will be observed before addition records are
added to the previous ones for generating the report.

< (Less Than) Report Limits Delay. This selection uses the Report Ranges and Limits.

5.
When “< Report Limits Delay” is selected the report generator only examines the data before the
specified delay time, added to the first data record that was detected within a specific range. Other
than this difference, this option behaves much like the greater than (>) option.

Interpreting the Report

One Channel Block from a Report

In our report example, each channel block has three sections: Average Values, LoLo-HiHi Limit Values,
and Status. Each of these sections includes a grid made up of rows of the RPM ranges that were selected
for the report, and columns of Spectral Bands. If the Default Limits were used to generate the report, only
one row would have appeared in the grid since there are no limit ranges when the Default option is
selected.

The first section of the block (see figure) contains the results of the analysis of the data. In this case it is
the

Average Values for all the data. If Out of Ranges was included in the report, this is the only section

where that specific row will appear in the grid. In the example report, each cell in the grid contains the
Average value of all the data for a specific Spectral Band that was gathered for a specific RPM range. For
example, in Channel 1 -labeled Accel Ch 1- the cell under the Overall spectral band column, in the 400 to
799 RPM range row has the value of 0.0250. This means that all of the Overall Band readings, ob tained at
an RPM range of from 400 through 799 RPM, ha ve an A ver age val ue o f 0. 02 5 0. The nu mber of readings
that were obtained while the Turbine was running in that speed range is not displayed.

The grid cell under the Overall spectral band column in the Out of Ranges ro w has a val u e of 0. 03 1 0. This
means that all of the Overall Band readings, obtained at an RPM range that was not within any of the three
RPM ranges shown, has an Average value of 0.0310. The number of readings that were obtained while the
Turbine was not running within any of the three selected RPM ranges is not displayed.

The second section in the report (
configuration dialog for each Spectral Band and RPM range. Since Average was selected for the report, an
upper and lower limit is needed for the report. The selected upper and lower limit is shown in the green
shaded area; and the values of these limits are displayed in the grid. As you can see in the report, the
LoLo and HiHi limits were selected, and for the Overall spectral band in the 400 through 799 RPM range,
the lower to upper limits extend from a value of 0.2000 to 1.8000. If a spectral band has zero value for it's
associated RPM range, the Limits cell in the grid displays a "-" character, indicating that the value in the
cell is ignored.

The third (

Status) section of the report displays the Pass/Fail results of the Analysis. As stated above, the

Overall spectral band average value for the 400 to 799 RPM range was 0.0250 and the LoLo to HiHi limits
settings for the same spectral band and RPM range were 0.2000 to 1.8000. Since the value of 0.02 5 is
outside of the range of 0.2 to 1.8, the results of this spectral band/RPM range test resulted in a failure
condition. This is indicated by the word Fail in the Status grid cell [in the Overall spectral band column]
and in the 400 to 799 RPM range row. If a spectral band has zero value for its associated RPM range, the
limit value is ignored for the test and a dash (-) is displayed in the grid. This indicates neither a Pass nor
Fail condition for that value.

If any of the cells in the Status grid contain a Fail state, the right edge of the channel block is set to red, and
displays the word Fail.

If all of the cells in the grid contain a Pass state, the right edge of the channel block is set to green, and
displays the word Pass.

If each cell in the grid contains a dash (-) the right edge of the cell is set to yellow to indicate that neither a
Pass nor a Fail condition exists. In this case no text appears.

If any of the channel blocks indicate a Fail condition, the Test Status line in the report header displays the
word Fail, as shown in the following figure.

If all channel blocks indicate a Pass condition the Test Status line in the report header will display the word
Pass. If all channel blocks indicate a non Pass/Fail condition, Test Status line in the report header is set to
yellow and displays "n/a". In regard to the Test Status, the XL Report dialog has both Pass Text and Fail
Text entry fields where you can customize text to use in place of the “Pass” “Fail” defaults.

Auto Format

The XL Report generator includes an Auto Format option. When you select Auto Format you are
instructing the software to automatically include the entire eZ-TOMAS report in the Excel worksheet’s
print area. With Auto Format selected, the report’s page will automatically orientate to portrait or

Network Menu [In Gauge Window] 9

This feature requires multiple copies of eZ-TOMAS, one on each networked computer. Each networked
computer must have eZ-TOMAS running in order to access the networking functions.

When networked, a node is set as either a client or a server. The server computer is the one which is
connected to the data acquisition hardware. It can be monitored by one or more remote client computers.
The client PC does not need to be connected to acquisition hardware, e.g., no Zon icBook, WaveBook, or
Medallion connection is required for the client machine.

In the server computer’s Configure Network Nodes window [accessed from the Network pull-down
menu] you will need to enter the remote computer’s network identification name or its IP address. You
should contact your network administrator prior to making the network configuration. Even if you know
the computer name and or IP address, the network administrator should be informed of your intent.

In the client computer’s Configure Network Nodes window you will need to enter the server computer’s
network identification name or its IP address.

Connecting to a Network Node

Find the computer you wish to connect to in the network node list, and left-click on it.
eZ-TOMAS will establish the client/server relationship. Once a network connection is
established, a connection icon (two computers connected by an arrow) and a disconnect button
(a large “X”) will be displayed. The name of the computer connected to will also appear between
the two buttons. In the above figure the computer is 100312.

Network Status Messages

There are four status messages that can be displayed in the Options panel of the Gauge window.

When not connected, the message: “Listening to Netw ork .. . ” appears.
While searching for eZ-TOMAS on another PC, the message:

“Connecting to <computer name> on port <number>...” appears.

If acting as a client that is connected to a server, the message will read:

“Received” and the current time will be displayed.

If acting as a server, and a client has connected, the message:

“Network Xfer Timer” will appear, followed by a number in seconds.
(See upper right figure).

Security Pull-Down Menu

eZ-TOMAS has 3 Security Levels.

• User Level 1 has very limited privileges – Exit, Print, Generate Alarm Log Report, and View

Gauge data in the Main menu.

• User Level 2 has a few limitations. Level 2 operators cannot start a new project, erase the History

file, or change the security password.

• User Level 3 has full privileges, which include the ability to start new projects and erase History

files. Level 3 is password protected.

After selecting User Level 3, a dialogue box similar to the following will appear. The user must enter the
project’s Level 3 password to enable full privileges.

No password is required to go from Level 3 down to Level 2 or to Level 1. However, the project password
is required to move from Level 1, or Level 2, to a higher level.

Security Level 3 Dialog Box

Appendix A - Using Function Keys A

tomasfkeys.ini

The tomasfkeys.ini file, distributed with eZ-TOMAS software, makes it possible to use your keyboard’s
Function Keys (F1 through F12) in conjunction w ith eZ-TOMAS. Through the ini file, you can set the
Function Keys to open frequently used projects.

The task of each Function Key is determined by how it is defined in the tomasfkeys.ini file. The following
table includes several definitions. In every case the first 4 characters are Fnn=, where the letters “n”
identify the Function Key of interest, e.g., F01 represents the F1 key, F02 the F2 key, etc. Each function
setup must start with the Fnn= syntax.

Example of Function Key Application

Key Function Setup in tomasfkeys.ini Function
F1 F01=HELP
F2 F02=ACQ
F3 F03=LC
F4 F04=SAVE

F5 F05=
F6 F06=
F7 F07=
F8 F08=

F9 F09=PRINT
F10 F10=

Customization

You can customize the Function Keys for eZ-TOMAS by completing the following steps:

1. Open the tomasfkeys.ini file in the Notepad application, or in a similar text editor. Note that

if you double-click on the ini file it will automatically open in Notepad, providing you have
that application.

2. Type new Function Key definitions, or edit the ones you want to change.

For example, for the F5 key, a user might enter: F05=d: \program files\data\turbine.tom3
where d:\program files\data is the path and turbine.tom3 is the file.

3. After you have made the desired changes, save the edited tomasfkeys.ini file.

Note: If eZ-TOMAS is running, you will need to close the program and restart it before the

changes go into effect.
