SECTION 1 — GENERAL INFORMATION

1.1 INTRODUCTION

For the first time, all necessary properties of the gases in the condenser exhauster line are directly
measured to provide an accurate determination of air in-leakage and condenser performance related
parameters. These properties are measured to provide the power industry with the most advantageous
and complete product for condenser system diagnostics:

the RheoVac®System*

*USPNs 4,255,648; 5,485,754; 5,752,411; 6,526,755

A model 950 RheoVac system consists of one, two or three probes reporting to a central signal
conditioner and processor unit. The sensing probe, consisting of multiple sensors configured in a single
probe head, is installed in the vacuum line between the condenser and the exhauster. The RheoVac
system is superior to all other methods in that it makes no assumptions about the dynamic condenser and
vacuum line environment. The sensor head employs the patented Rheotherm
an accurate mass flow measurement. Additionally, temperature, pressure and water vapor relative
saturation measurements are made using a high accuracy platinum resistance temperature detector
(RTD), a strain gauge pressure sensor and a specially configured and calibrated water vapor saturation
sensor.

1.2 PRINCIPLE OF OPERATION

The principal features of the RheoVac system are shown in Figure 1. At the heart of the RheoVac
system is the Rheotherm mass flow transducer, which uses the same patented thermal sensing technique
employed in all precision flow instruments manufactured by Intek. Two temperature sensors are used
one sensor is in thermal equilibrium with the flow medium and provides a temperature and flow signal
reference, while the second sensor is located near a constant power heater so that its temperature is
always above that of the fluid. The temperature of the heated sensor will vary with the stream velocity
of the fluid. Hence, the measured temperature differential between the reference sensor and heated
sensor is a function of flow rate, which is approximately proportional to the logarithm of mass flow rate
(USPN 4,255,968).

The Rheotherm flow sensor is calibrated to measure the total mass flow of the gaseous water vapor/air
mixture. From the other three measurements, the RheoVac electronics converts the total gas mass flow
signal from the probe into two components, air mass flow rate and water vapor mass flow rate. This
unique measurement method is disclosed in two separate patents (USPN 5,485,754 & 5,752,411).

The RheoVac system is fully calibrated in the factory under dynamic fluid conditions identical to those
within the power plant vacuum line. No field adjustments are required.

location.

- 2 -

Use reasonable care in handling the probe the sensing components are delicate. Do not
bend the probes, damage the tips, or obstruct the sensing ports. If shipping the unit, make sure
the probe is adequately protected from foreign objects and damage.

Use proper input power it must be between 100 and 250 Vac (nominal 120/240 Vac) at
50/60 Hz (60 Hz nominal).

Confirm the line and environmental temperature is always below the probe and electronics
ratings never operate a probe at or subject it to temperatures or pressures beyond its
specified limits. (See Section 1.3)

.. WARNING - Never allow live high temperature steam to flow either direction in the

exhauster line where a probe is located. This can happen if steam jet ejectors are
operated incorrectly.

.. WARNING - Do not allow the instrument’s RS sensor (or separate RS probe) to come

into contact with liquid water, water mist, or fog – these conditions may be present in
your condenser vent line due to design configuration. The RS sensor measures relative
saturation up to 100% but may fail under the above wet condition. Intek provides design
services to improve condenser venting and reduce or eliminate entrained liquid water and
excess condenser back pressure.

Keep moisture out of the enclosures once all service connections are made, make sure the
enclosure lids are tightly closed and all gaskets are in place. Seal all conduit lines.

.. WARNING - Be sure to power up your RheoVac instrument system and probe(s) for

at least 30 minutes before inserting probes into the vent line hot taps. DO NOT leave
probe in vent line unpowered or when flooding the condenser.

SECTION 2 — INSTALLATION

2.1 INSTALLATION

These instructions cover installation of RheoVac instruments in their standard configuration. Additional
information pertaining to your unit is covered in SECTION 6 CUSTOM INFORMATION . Carefully
read these instructions prior to installing the equipment. Also, see preceding SECTION 1.4.

2.2 RheoVac SYSTEM INSTALLATION/SITE SELECTION

The RheoVac 950 can be configured with one, two or three probes. A three probe system is intended
to be installed so that one probe is in each of the two exhaust lines coming out of the condenser (A side
and B side). The third probe should go in the header pipe that runs to the exhauster(s). Other
installation arrangements of multiple probes should be discussed with the factory.

2.2.1 Probe Site Selection

# The location for each probe should provide the probe sensing area with well-established

smooth flow, uniform system temperature and pressure, and consistent non-liquid phase flow
medium. Pipe sections ahead of a probe, in which water can accumulate, must be avoided.
Refer to Figure 2 and select the most preferred location for each probe. Do not install the
probes beyond any “trap” sections as shown in Figure 2, Configurations B and D. Special
installation instructions unique to your unit, where applicable, will be noted in SECTION

6.3 SPECIAL INSTRUCTIONS. Refer to this section now to review special instructions.

Figure 2 RheoVac Probe Insertion Recommendation

- 4 -

# Check installation clearance. Each transducer probe is almost 3 feet (0.9m) long and the hot

tap assembly is approximately 13 inches (0.33m) long, therefore, allow minimum clearance
of 4 feet (1.3m) for probe installation. Be sure there are no obstructions around the vacuum
line that will interfere with probe insertion. Figure 3 shows the proper insertion angle. THIS
ORIENTATION IS IMPORTANT FOR PROPER OPERATION.

# Observe the selected sites. They should be convenient for the removal and replacement of

probes at any time for service without building scaffolding or waiting for plant shutdown.

# Check operating conditions. The temperature and pressure limits (see Technical

Specifications; Section 1.3) of the unit should be checked to ensure compatibility with your
application.

# Gases in the air removal line should be free of liquid water, mist or fog. Wetness in the line

will result in erroneous readings from the instrument. If wet conditions exist in the air
removal line, there is either air removal section damage or design flaws which adversely
affect condenser performance. Consult Intek for assistance in evaluating the severity of the
problem and possible remedies.

2.2.2 Electronics Unit Site Selection

The Model 950 typically has two or three electronics enclosures (see Figure 1). The processor
enclosure and other electronics boxes should be installed in a convenient location and should be
kept away from direct sources of heat, such as uninsulated steam lines, or moisture. The
maximum temperature rating of electronics is 120°F; ensure that this temperature will not be
exceeded. Once the wiring connections are made, close and latch down the box lid to protect the
contents from damage and debris. All these enclosures should be located in a dry area and should
be kept clamped shut during normal operation. Do not allow water to get into the enclosures. If
installed outdoors, build a roof over all enclosures to prevent eventual water infiltration.

A. Processor Enclosure: This 12x10 NEMA 4 enclosure houses the display and central

processing unit. Input power (100-250 Vac, 50/60 Hz) is connected inside this enclosure.
This enclosure should be installed in a convenient location and should be kept away from
direct sources of high heat, such as uninsulated steam lines.

B. Distribution Box: This 8x6 NEMA 4 enclosure is typically located near the probe that is

closest to the processor enclosure unit. It is connected to the main processor with an RS-485
bus DeviceNet™ cable, which can be hundreds of feet long. The probe and transmitter RS­485 cable connections are also made within this box. The probe and transmitter cable
lengths should be 15 ft. or less, if possible.

C. Transmitter Box (optional): This 10x8 NEMA 4 enclosure contains terminals for accessing

the eight 4-20mA signals. It can be located in or near the control room so that the 4-20 wires

do not have to be run from the plant floor. An RS-485 DeviceNet cable runs from the
distribution box to the transmitter box. (There are restrictions on how this can be done, so
check manual Section 6, or contact the factory.)

2.3 MOUNTING HARDWARE INSTALLATION

Î Check hardware. Verify that the probe slides through the hot tap assembly.

Ï Check installation configuration. Make sure the probe is parallel to the floor (see Figure 4).

Be sure location is accessible for probe removal and maintenance.

Ð Check installation clearance. Verify there is a minimum probe insertion clearance of 4 feet

(1.3m) between pipe surface and any obstruction.

Ñ Install the mounting hardware. Drill a 1½” through-hole, center the thread-o-let over the

hole and weld it onto the condenser vacuum pipe (see Figure 4). Thread the hot-tap
assembly into the thread-o-let. Use thread tape or pipe dope to seal the connection.
(Alternate: weld thread-o-let to pipe wall, then drill a 1¼" hole in pipe wall using a hot-tap
drill.)

Ò It may be necessary to apply a force of about 23 lb (102 Newtons) to remove or replace the

probe under plant operating conditions.

2.4 PROBE INSTALLATION AND ORIENTATION

Î Check proper installation direction. Each probe has a directional

arrow on the junction box. Before installing the unit, note proper
flow direction. This is important to instrument operation.

Ï Check serial number (S/N). If more than one RheoVac unit has been

purchased, make sure the first five digits of the serial numbers of the
probe(s) match the first five digits of the serial number of the main
processor unit. The electronics and up to three probes are a matched
set. Mismatched components will not work correctly. The dash
number on the probe S/N is the probe number shown on the display.
Record the probe number and installation location for future
reference.

Ð Verify stop clamp location (see Figure 3). A stop clamp is attached

to each probe as an indication of its insertion depth. It is important
that the stop clamp is securely in place to position the sensors in the
correct location and to ensure that the probes do not contact the
opposite pipe wall. Contact with the pipe wall could damage the
probe. The clamp’s location was determined based on your
submitted pipe diameter, as shown in SECTION 6.2, and is marked
with a groove on each probe shaft. Refer to this mark if a stop clamp
is inadvertently moved. The two metal probe tips should be in the
middle of the pipe.

Figure 3

Probe Stop Clamp

Figure 4 Transducer Installation Detail

- 7 -

Ñ Inspect the probe tips. Be sure wetted surfaces are clean before installing. If cleaning is

needed, use a damp cloth wetted with alcohol and wipe dry using a second dry, soft, lint-free
cloth. Do not immerse probes in alcohol or any other liquids. This may damage the probe
sensors.

Ò Be sure to power up your RheoVac instrument system and probe(s) for at least 30 minutes

before inserting probes into the vent line hot taps. DO NOT leave probe in vent line
unpowered or when flooding the condenser.

Ó Install each probe. The probe should be mounted through the pipe wall using the hot-tap

assembly. The probe installs so that the two sensor tips are side-by-side across the gas stream.
The probes have a flow directional arrow on the junction box. When installing under vacuum,
do not allow the clamp to "slam" against the seal nut upon opening the valve. Grasp the probe
firmly, with hand against the seal nut, before opening the ball valve. Allow the probe shaft to
slide slowly through the valve by controlling the amount of grip on the probe shaft. Special
installation instructions, if any, will be noted in SECTION 6.

Ô Prior to inserting probe, loosen the compression nut on the thermocouple connector of the hot

tap and clean the inner surface of the thermocouple connector to ensure it is free of particles
that may cause probe damage.

2.5 ELECTRICAL CONNECTIONS

. IMPORTANT . Inspect and VERIFY these electrical connections carefully. Improper

connection could damage electronic components and sensor function. If additional holes need to
be drilledin the processor enclosure, remove the electronicssubassembly (mounted ona mounting
plate) and temporarily store inside an ESD bag in a safe, clean place. Do not drill with electronics
boards inside the enclosure.

E. Cable Connection from Probe to Distribution Box

The RheoVac probes require special connectors to be installed on the supplied DeviceNet
type 5711 cable sections that go from the Distribution Box(es) to the probes. The probes
have the male mating connectors already installed. These connectors will use either the
“backshell nut” or “conduit connector” (see Figure 10) depending on whether the cable is
installed in a liquid-tight conduit. When installing without conduit, use the backshell nut;
when using liquid-tight conduit, use the conduit connector with o-ring.

1. Slide all of the appropriate parts onto the cable as shown.

2. Strip the cable conductors as shown. The connector (Turck p/n B4151-0/9) has 5 retention
screws to hold the wires in place. The use of crimp pins on the wires will greatly increase
connection reliability.

3. Loosen all 5 retention screws (do not completely remove).

4. Insert the wires, in accordance with color-coding shown (see Figure 6, insert).

5. Tighten the retention screws on each wire.

6. Reassemble the connector parts (Figure 10).

SECTION 3 — OPERATION

3.1 GENERAL INFORMATION

The RheoVac system is calibrated, compensated, and linearized for a wide range of flowing media
temperatures, pressures, and water vapor contents. However, abrupt changes in these parameters can
cause the instrument to temporarily read the flow rate improperly, which could lead to transient spikes
in the flow indication. In particular, if liquid (water) hits the probe tips, there will be high flow
indications until all the water vaporizes. If liquid (water) is present for extended periods, the
performance of the instrument will be compromised or the sensors can be damaged. See SECTION 2

INSTALLATION.

3.2 SYSTEM START-UP

Verify wiring from SECTION 2.5 is correct. With all power off, place the power OFF/ON switch,
SW1, to “ON.” Close the main processor enclosure lid. While watching the main processor display,
apply power to the instrument. After about twenty seconds the display should initialize to “Health
Check in Progress” followed by additional initialization status messages. Within two minutes the
display should indicate “Air In-Leak.”

Upon a "cold" initial start-up of the RheoVac system, the probe may take several minutes to give
accurate readings. During this time, the probe is transitioning to thermal equilibrium conditions under
vacuum.

3.3 PORTABLE USB DATA STORAGE DEVICE/Warranty Registration Instructions

Intek’s warranty program is stated at the front of the manual. To validate warranty, return the portable
USB Data Storage Device after the RheoVac instrument has been in operation with the unit on-line for
one week.

To return the portable USB Data Storage Device to Intek:

Î Locate portable USB Data Storage Device in the main electronics enclosure (see Figure 5).
Ï Grasp bracket and carefully remove portable USB Data Storage Device.
Ð Place portable USB Data Storage Device in the pre-addressed, padded envelope provided

by Intek and mail.

The initial data stored in the device is used to verify proper operation of the RheoVac instrument and
is required to provide baseline data for future technical support.

.. CAUTION Do not attempt to use non-Intek approved USB flash drives with the RheoVac

instrument.

- 14 -

3.4 DISPLAY

The RheoVac 950 has a 2x20 alphanumeric scroll-through display that shows seven parameters for each
probe. The display shows Air In-leakage, W/A Mass Ratio, Total Mass Flow, Temperature, Pressure,
Relative Saturation, or Actual Volume Flow (as well as Time/Date, Software Version, or Serial
Number). To change the displayed parameter, press the Scroll Up or Down arrows. The display units
can be changed from English or Metric units by pressing the Units button.

If the Model 950 has two or three probes the display will show two or three serial numbers at a time,
one for each probe. The numbers will be in order, from the lowest serial number to the highest, reading
from left to right on the display. Example: 02611-1, 02611-2 and 02611-3.

3.5 COMMUNICATIONS

Typical RheoVac 950 instruments have an Ethernet port, two serial communications choices (RS-232
or RS-422) and eight 4-20mA output signals for each probe. Each process variable is a linear, fully
temperature and pressure compensated value on any of these readable outputs. All 4-20 mA output
signals are scaled such that 4 mA represents 0% of the rated full scale value (except temperature, which
is 0°C) and 20 mA represents 100% of the rated full scale value (temperature is 100°C). The standard
full scale values and definitions of all process variables are listed in Table III.

A very important part of understanding your condenser system comes from evaluating the data that is
created and stored by the RheoVac instrument. The ability to evaluate data has been greatly enhanced
with the RheoVac Model 950 by providing nearly unlimited data storage capacity. A data file is created
for each calender day that the monitor is operating. The ability to review stored data has been invaluable
when troubleshooting condenser problem s.

The importance of reviewing graphed data cannot be overstated. Reviewing data for normal operating
conditions will greatly decrease the time needed to troubleshoot problem conditions when they arise. To
simplify the graphing process, an Excel add-in has been created by the technical support team at Intek
and is included with your RheoVac user software. This Excel add-in graphing utility, called
RheoGraph, is an automated graphing macro that imports and graphs RheoVac data files.

The RheoGraph utility is contained in a self-extracting zip file called “InstallRheoGraph.exe” on the
User Interface software CD. Executing the file will begin the menu driven installation process. The
default installation path is to C:\RheoVac, do not change this path nam e during installation. The file
RheoGraph.xla will be copied to the installation folder along with help files, sample data, and a readme
text file. Microsoft Excel is required for the add-in to function.

Executing RheoGraph.xla will launch Excel and the graphing menu will appear. Selecting Auto will
prompt the user to enter Company, Plant, and Unit info, which will be placed in the graph titles. Then
the user is prompted to browse to the data file to be graphed. The data will be inserted into a spreadsheet
page and four graph pages will then be automatically added as separate tabs in the workbook. When the
graphs are complete, macro execution terminates.

Several advanced features are available by selecting Advanced on the Auto Start menu. For additional
help, use the keyboard arrow keys to set focus on any button, then press F1. The following is an example
of one of the graphs made by RheoGraph showing air in-leak and water vapor to air mass ratio.

3.7 CUSTOM SOFTWARE

Custom software may be developed by the user to receive and archive RheoVac data into a computer
system. The electronics has a serial data protocol of 9600 baud, no parity check, eight data bits and one
stop bit (i.e., 9600,N,8,1). Each transmitted group of data is sent in a standard ASCII coded format
representing each process variable value, instrument identification and status information.

The data stream consists of 13 fields, followed by a carriage return <RETURN>. The first ten fields,
nine bytes each, are the process variables. Following the process variables are the RheoVac serial
number, nine bytes, the process identification tag number, 15 bytes, and the RheoVac system status,
seven bytes. The data stream is then ended by a single <RETURN> byte (ASCII code 13). The total
number of bytes transmitted in each data stream is 122 bytes per probe including the trailing
<RETURN>. This data group is sent approximately once every three seconds. Table V shows the field
names and number of bytes in one data stream.

SECTION 4 — MAINTENANCE

4.1 GENERAL MAINTENANCE

Precautions should be taken to insure proper performance of all sensors. Since the quantification
technique involves signal measurements, care should be exercised to prevent build-up of dirt and/or
corrosive layers on the various terminal strip connections. Periodic checks with necessary cleaning
should be performed to insure clean terminals. The joints of the sensor leads should occasionally be
inspected for corrosion or presence of moisture.

4.2 CALIBRATION

The RheoVac instrument is calibrated at the factory in a calibration system which replicates the
condenser and vacuum line environment. The system is designed to simulate the temperature, pressure,
water vapor relative saturation and flow rate under the gaseous fluid conditions found within the power
plant vacuum line.

In general, calibrations should be valid over a two year period if the probe is well maintained. Should
the unit require re-ranging or recalibration, note the serial number of the RheoVac instrument and
contact the factory concerning recalibration cost and turn around times. Refer to SECTION 5
CUSTOMER SERVICE of this manual for additional information.

4.3 SPARE PARTS

It is advantageous to have a spare probe. Should a spare probe be desired, it can be ordered and stored
for installation at any time. A spare probe will come with a parameter disk for uploading from a laptop.

Spare fuses should be available for replacement of blown fuses. Appropriate fuses to stock are:

500 mA fuse, slow blow, Wickmann part number 3720500041 or equivalent, for probes.
1 A fuse, slow blow, Wickmann part number 372110041 or equivalent, for the main electronics.

There are no other normally recommended spare components to stock.

To replace the fuse in the main electronics: locate the AC Power Input board (shown in Figure 5) in the
lower right hand corner of the main electronics box. Slide the power switch to the “OFF” position to
disable power to the electronics. The fuses are shown at locations F1 and F2 (spare). Gently pull the
fuse(s) from their sockets and gently insert the replacement 1 Amp fuse(s) as appropriate. Slide the
power switch back to the “ON” position to enable power to the electronics. Close hinged lid and verify
display backlight is on. Clamp close the enclosure lid, and tighten the latch screws.

APPENDIX A - RheoVac® Instrument User Interface Software

A.1 INTRODUCTION

User Interface Software (UIS) is provided on CD-ROM with every RheoVac instrument. This
software is used to communicate with the RheoVac unit from a User Interface Computer (UIC).
Some of the functions of the software can be performed using a serial cable, while all functions are
available using an Ethernet connection. An Ethernet crossover cable is provided with each RheoVac
instrument for the purpose of connecting a UIC directly to the RheoVac unit. The network functions
are also capable of being used from any network computer if the RheoVac instrument is connected
directly to the same network. In this case, the supplied crossover cable is not used; rather a straight,
high noise-immune Ethernet cable with RJ-45 plug is used (supplied by customer).

Most details regarding use of the software can be found in the active help files from the pull down
Help menu when using the software.

A.2 SOFTWARE INSTALLATION

A User Interface Computer (UIC) is required to access stored data and real time data of all
parameters. A laptop is suggested for easy access to the main processor unit. Intek does not supply
UICs but recommends the following System Requirements (minimum recommended):

Minimum System Requirements:
Windows 98, Windows NT, Windows 2000 or Windows XP Operating Systems
Pentium III, 400 MHZ processor with 128 MB RAM
SVGA 800 x 600 display
One CD-ROM drive
One 10/100 Ethernet Port

Recommended (Optional):
One 3.5 inch floppy disk drive (probe recalibration data files can be provided on diskette)
One RS-232 serial port with DB-9 connector

The User Interface Software should be installed onto the User Interface Computer. Install the
software by inserting the CD-ROM supplied with the manual into the CD-ROM drive and follow
the on screen prompts. A folder, C:\RHEOVAC will be created and files will be copied to this
folder. The executable file is RheoVac User Interface.exe and the others are drivers and
configuration files that must remain in the RHEOVAC folder. If a previous version of User

nd

Interface Software is on the UIC, you will need to launch the installer a 2

time.

A.3 USER INTERFACE SOFTWARE (UIS) SELECTION

After installation, the user interface is initiated by selecting [START\PROGRAMS\RHEOVAC\
RHEOVAC USER INTERFACE]. The main menu appears, prompting for a selection of RS-232
Serial Communication or Ethernet Communication Utility. A list of functions for each utility
appears below the green selection buttons.

I:\OFFICE\WPMANUAL\RV950 APPENDIX A3.wpd January 29, 2007

- A1 -

Make sure the proper cable connection has been made and select the desired communication type
by clicking on either green button.

Figure A - Initial UIS computer Screen

A.4 RS-232/422 COMMUNICATION

This function requires a serial cable and connector, available on request, to connect the UIC and the
RheoVac instrument electronics. This connection allows the user to view real time data of important
parameters in a convenient gauge screen layout. From this gauge screen, the user may choose to
graph a single parameter for all probes, graph all parameters for a single probe, or archive data
directly to the UIC. The archive rate can also be adjusted. These are the only functions available
using serial communication. No commands or updates can be sent to the RheoVac instrument using
this communication method.

A.5 ETHERNET COMMUNICATION

User interface using Ethernet connection allows the user to: synchronize the RheoVac clock with
the UIC clock, retrieve stored data

1

, update files1, change line size, and access data. These network
access utilities are performed from a user interface computer (UIC) connected directly (peer-to-peer)
to the RheoVac unit using a crossover network cable or from a network computer when the RheoVac
instrument is connected to a network (LAN/WAN)2 using a straight Ethernet cable.

Each RheoVac instrument is identified by a unique network ID. The ID begins with the letter “R”
followed by the first five digits of the serial number found on the unit. (RheoVac Model 950 devices
which have not been serviced by the factory since 2005 may use the serial numbers or “RheoVac

950" network ID). The user must select the network ID from the pull down menu following the
selection of Ethernet Communication utility from the Main Menu. If the Network ID is not in the
list, select Add New ID and enter the correct six character Network ID. When a new ID is added
to the list, it will be saved as the default for later use. Selecting the correct ID will initiate
communication with the RheoVac instrument. Software features, in addition to those detailed above,
are described within the User Interface Software itself.

A.6 SOFTWARE OPERATION

1. Set Clock

(available with Ethernet connection only): Initiating this action will reset the
RheoVac time clock to agree with the time on your UIC. Make sure the UIC has the
correct time before proceeding.

2. Change Line Size (available with Ethernet connection only): Use this option to update

the instrument’s stored line size variable for proper volume and mass flow calculations.
You should only need this option if the probe is installed in a pipe size that is different
from the value set in the instrument at the factory. In Ethernet Communication, click on
the Line Size tab. On the pull down menu for pipe size, click on the new value, then click
on Save. Click Load to verify that the change was saved by the instrument.

3. Update Files

following format:

MMDDYY - P.dat
where MM = two digit month

DD = two digit day
YY = two digit year
P = probe designator (1, 2, or 3)
.dat = file extension

These data files are stored in tab delimited text format. See SECTION 3.5 to process data.

To copy a file for analysis, you must access the files on the RheoVac instrument. Open
Windows Explorer on the UIC. Type \\Network ID\RHEOVAC\DATA (Network ID is
generally “R” plus the first 5 digits of the serial number; see section A.5) on the address
line and press enter. Be careful not to alter any support files in this data folder. Use
the copy/paste functions (copy - Ctrl C; paste - Ctrl V) to put data files (.dat) on the
UIC.

5. Monitor Data

(available with Ethernet or RS-232 connection): Once RS-232 or Ethernet

is selected, the first screen, Figure B, shows the most recent value for each parameter.

appears.

Figure C - User Interface Software Graph Feature

I:\OFFICE\WPMANUAL\RV950 APPENDIX A3.wpd January 29, 2007

- A4 -

This screen can be divided into four parts:

1. The Chart (or charts)

2. The X-Axis Controls

3. The Legend

4. The User Menu

These four parts work together in the following ways: As soon as the software is opened and valid
communication is established, the data collected for each probe is plotted on the chart(s). The
newest data points are displayed on the right of the chart and push older data points to the left, much
like many old-style strip chart recorders.

The horizontal scroll bar immediately below the chart(s) can be used to select which data points (i.e.,
data from a specific timestamp) from the chart are displayed on the legend below. Data points can
be selected either by clicking-and-dragging the scroll bar pointer or by simply single-clicking a spot
on the scroll bar.

The four buttons below and to the left of the scroll bar labeled 30 min, 1 hour, 2 hour, and 4 hour
can be used to quickly set the x-axis range of the chart(s) and the scroll bar. When using these
buttons keep in mind that the maximum x-axis value is always used as a reference and only the
minimum displayed x-axis value will be changed. You can also change both the minimum and
maximum x-axis value by double-clicking them with your mouse and entering a new value with
your keyboard. Changing the range of the chart (X or Y axis) changes only the data that is displayed
and does not delete or alter the data in any way.

The blue block (time/date) to the right of the 4 hour button displays the timestamp for the data point
currently being pointed to by the horizontal scroll bar. If the scroll bar is in the right-most position,
this value will automatically update when new data is received from the connected instrument.

The legend at the bottom of the screen displays the value of the data being pointed to by the scroll
bar and also is used to control where each data parameter is plotted. To access this feature single­click on any parameter in the legend. Two things will happen. First, the background color of the
selected parameter will change in the legend, and second, the parameter will disappear from the
chart if you are in single-chart mode or jump from one chart to the other if you are in dual-chart
mode.

Single-chart and dual-chart modes are the first two selections available in the chart user menu. Also
available in the chart menu are selections to choose between manual and auto scaling for the y-axis
and to reset the maximum x-axis value to the most recently collected data point.

The legend menu is used to select which parameter or which probe is displayed. If a parameter is
chosen from this menu, that parameter will be displayed for all probes connected to the instrument.
If a probe is selected, then all parameters for that probe will be displayed.

The archive menu is used to set the rate that data will be archived to the hard disk of the computer
on which the user has installed the User Interface Software. These selections have no effect on the
data that is stored every minute on the hard disk of the RheoVac instrument itself. Data archived

I:\OFFICE\WPMANUAL\RV950 APPENDIX A3.wpd January 29, 2007

- A5 -

to the user’s hard disk is stored in the “C:\RHEOVAC\DATA\” directory. The data is subdivided
into folders for each probe. A new file for each probe will be created each day that data is archived.

A.7 WARRANTY REGISTRATION/TECHNICAL SUPPORT

Sending Data to Intek:  IMPORTANT 

If the instrument is equipped with a portable USB data storage device as shown in Figure 5 (in the
main manual), remove this storage device after one week of operation and send to "Intek, Inc., 751
Intek Way, Westerville, OH 43082" to activate/secure warranty registration. This storage device
is programmed to capture the initial baseline data recorded by the RheoVac instrument.

The following paragraph is applicable to RheoVac 950 instrument users only:

The availability of plant data for periods corresponding to the RheoVac data are important to proper
diagnostic evaluation. Plant data of interest to the factory for the same time period are: turbine back
pressure, hotwell temperature, load, and inlet and outlet circulation water temperatures. The plant
data is necessary for correlating RheoVac measured data. The availability of this information at the
factory is very important to Intek’s ability to assist you in troubleshooting your instrument and/or
to respond to inquiries. This provides a baseline for the system and will help us support you should

future system problems arise. Our experienced support engineers can access the “before” and “after”
effects of an upset and work with you to identify and understand the problem, and develop solutions.
Additionally, most air removal piping conditions that are detrimental to probe operation can be
diagnosed before probe damage occurs. For this reason, we require a data download one week after

RheoVac system is placed into service. The download activates the one year warranty service.

the

Alternately, you may send to the factory an initial week or so of data (zipped format is preferred). The
simplest way is to copy all data files and the ‘event.log’ file to your UIC and send it via email to
[e-mail].
