SECTION 1 — GENERAL INFORMATION

1.1 INTRODUCTION

For the first time, all necessary properties of the gases in the vacuum dryer exhaust line are directly measured to provide an accurate determination of water vapor removal and dryer performance related parameters. These properties are measured to provide the industry with the most advantageous and complete product for vacuum dryer system diagnostics:

the RheoVac

A RheoVac DR system consists of sensor probes reporting to a central signal conditioner and processor unit. The sensing probes, consisting of multiple sensors configured in two separate probes (the standard configuration is a main FTP probe and a RS probe), is installed in the vacuum line, generally between the dryer and the exhauster. The RheoVac DR system is superior to all other methods in that it makes no assumptions about the dynamics of the dryer and vacuum line environment. The main FTP probe sensor head employs the patented Rheotherm® technology to provide 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 DR system are shown in Figure 1. At the heart of the RheoVac DR 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 water vapor/air mixture. From the other three measurements - temperature, pressure and relative saturation - the RheoVac DR electronics converts the total 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 DR system is fully calibrated in the factory under dynamic fluid conditions similar to those within the dryer vacuum line. Typically, field adjustments are not required.

1.4 PRECAUTIONS AND RECOMMENDATIONS

Read the entire manual before installing and operating the RheoVac DR system.

Carefully select the best location for installation of the probe(s). Access, clearances, freedom from standing water, and straight-run should all be considered when selecting probe locations.

Use reasonable care in handling the probes the sensing components are delica te. Do not bend the probes, damage the tips, or obstruct the sensing ports. If shipping the unit, make sure the probes are adequately protected from foreign objects and damage; save and reuse factory provided custom probe protector and shipping boxes.

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 line where a probe is located.

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

The RJ45 is the recommended network connection for all data traffic (as opposed to serial and 4-20 mA communication).

Intek recommends a service contract to ensure probes are within calibration specifications and electronics are maintained with appropriate updates. Instrument probes should be returned to the factory for inspection and calibration service every two years.

SECTION 2 — INSTALLATION

2.1 INSTALLATION

These instructions are generalguidelines for the installation of RheoVac DR 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 PRECAUTIONS AND RECOMMENDATIONS.

2.2 RheoVac DR SYSTEM INSTALLATION/SITE SELECTION

The RheoVac DR can be configured with one or two probes, with the two probe being the standard configuration. In the standard two-probe configuration, the main probe (FTP) is the larger probe, and the relative saturation (RS) sensor is located in a second probe, separate from the remaining primary sensors in the FTP probe. The RS probe is typically installed in the same line at a location slightly downstream of the FTP probe.

2.2.1 Probe Site Selection

The location for the probe pair should be selected so as to 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 the probe pair. 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.

Check installation clearance. The installation location should allow sufficient clearance for ease of probe removal (for servicing), including the required clearance space for the hot tap, where used. 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, particularly if liquid water is expected to wet the wall surfaces of the probe(s).

Observe the selected sites; check for ease of access. They should be convenient for the removal and replacing probes at any time for service; without requiring ladders, 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.

2.2.2 Electronics Unit Site Selection

The RheoVac DR system may have up to three electronics enclosures; a main processor box, an optional distribution box, and an optional transmitter box. These enclosures should be installed in a convenient indoor location and should be kept away from direct sources of heat. The maximum temperature rating of electronics is 120°F; ensure that this temperature will not be exceeded inside the enclosure. Once the wiring connections are made, close and latch down the box lid to protect the contents from damage and debris. The 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 potential water infiltration, or direct sunlight to overheat contents.

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 (optional): 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 RS-485 cable connections are also made within this box. The probe and

transmitter cable lengths should be 15 ft. or less.

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

the optional 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 connects 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 PROBE INSTALLATION

!!WARNING!! The FTP probe and the RS probe(s) contain components and materials that have a temperature rating limit of 210°F. If line and fluid temperatures are anticipated to exceed this limit, the probe(s) must be removed from the vacuum pipe before and must not be reinstalled until the problem condition has passed. Failure to do this can result in severe damage to the sensor probe(s), especially when steam enters the vacuum pipe due to vacuum pump operating anomalies. If Steam Jet Air Ejectors are used, always pump start up and do not reinstall the RS probe until stable operating conditions are achieved.

A. NPT/Hottap Installation

1. Check hardware. Verify that the probe slides easily through the NPT fitting or hottap assembly and pipe penetration hole.

2. Verify there are the necessary minimum probe insertion clearance four (4) feet- between pipe surface and any obstruction.

3. For NPT fitting installation, ensure that the threaded mating fittings (not provided) for mounting the sensing probe(s) are installed at the proper locations in the process line. Typically, 1" threaded couplings are needed for the FTP and the RS probes.

remove the RS probe from the line before

- 6 -

4. If using a hottap: install the mounting hardware; drill a 1½” through-hole, center the thread-o-let over the hole and weld it onto the dryer vacuum pipe; thread the hottap 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 1½" hole in pipe wall using a hottap drill.

5. Make sure the probes are parallel to the floor (see Figure 3). Be sure location is accessible for probe removal and maintenance.

B. Installing/Removing the Probe

1. Check proper installation direction and probe orientation. The FTP probe has a directional arrow on the junction box. Before installing the unit, note proper flow direction. This is important to instrument operation.

2. Check serial number (S/N). If more than one RheoVac DR system 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 probe pairs 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 pair number and installation location for future reference.

3. Verify stop clamp location (see Figure 4). A stop clamp is attached to each FTP 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 is 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. When installed in the line, the sensors in the probe should be positioned in the middle of the pipe.

4. Prior to inserting probe, loosen the compression nut on the thermocouple connector of the hot tap or the NPT fitting and clean the inner surface of the thermocouple connector to ensure it is free of particles that may cause probe damage.

5. Be sure to power up your RheoVac DR instrument system and probe pair for at least 30 minutes before inserting probes into the vent line. DO NOT leave probes in vent line without power.

6. Install probes. The probes should be mounted through the pipe wall using the hottap assembly or NPT fitting. a. The FTP probe installs so that the two sensor tips are

side-by-side across the gas stream. Each probe has a flow directional arrow on the junction box. Make sure the probe orientation is correct.

b. The RS probe does not have an orientation requirement.

The RS probe has a 4 foot (1.2 m) cable with a plug-in connector (with attached dust cap) for connecting to the FTP probe. Unscrew the dust caps on the RS cable and the FTP probe junction box, plug the cable connector in securely first, before inserting the RS probe in the line.

Clamp

7. When installing under vacuum, do not allow the clamp to “slam” against the seal nut

upon opening the valve. Grasp each 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. Do not let it slam against the seal nut. Once fully inserted, tighten the seal nut. Special installation instructions, if any, will be noted in SECTION 6.

8. It may be necessary to apply a force of about 23 lb (102 Newtons) to remove or

replace the probe under operating conditions. Firmly grip the probe shaft when removing a probe from the line.

2.4 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 drilled in the processor enclosure, remove the electronics subassembly (mounted on a mounting plate) and temporarily store inside an ESD bag in a safe, clean place. Do not drill with electronics boards inside the enclosure.

Power connection wires should be at least 18 gauge and comply with accepted wiring codes. SW1 on the power input PWA (printed wiring board #01011-5) is used for cycling power to reset.

3. Network Connection (Recommended)

: The Ethernet connection at CN3 on the CPU interface PWA (printed wiring board #08017-1) is an RJ-45 style jack. A 10-foot Ethernet Cat5 crossover cable is supplied with the unit for laptop connections. Intek recommends using this connection for all data transmissions and RheoVac communications because: a. More measured data is accessible

through the network connection.

b. Software and calibration file updates

can be done remotely.

4. Serial Communication: Connector JP3 on the CPU interface PWA (printed wiring board #08017-1) is the RS-232 serial communication interface. This interface should only be used for distances of 20 feet or less, such as to a laptop computer. A 20-foot serial cable with a DB-9 connector is available from Intekupon request (see Figure 6 and Table I). An RS-422 serial communication interface is present for long data communications when configured without 4-20 mA outputs. Note: Intek recommends using the

network connection for all data transmissions and RheoVac communications.

D. FTP Probe: CAUTION— Do not cross thread connection. The FTP probe is supplied with

a convenient plug-in connector. The male side of the connector comes installed in the probe junction box. The female side is usually shipped loose and must be installed onto the supplied DeviceNet type 5711 cable once it is run from the Distribution Box to the probe. The wiring detail for the female plug-in connector (Turck p/n B4151-0/9) can be seen in Figure 10. These connectors will use either the “backshell nut” or “conduit connector” 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 has 5 retention screws to hold the

wires in place. The use of crimp pins on the wires will greatly increase connection reli abilit y.

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

4. Insert the wires, in accordance with color-coding shown (see Figure 10, insert).

5. Tighten the retention screws on each wire.

6. Reassemble the connector parts.

SECTION 3 — OPERATION

3.1 GENERAL INFORMATION

The RheoVac DR system is compensated and linearized for a wide range of flowing medium temperatures, pressures, and water vapor content. However, abrupt changes in these parameters can cause the instrument to temporarily read improperly, which could lead to transient spikes in the flow indication. In particular, if liquid (water) contacts the probe tips, there will be high flow indications until all the water vaporizes. This is typically an infrequent occurrence and should not happen if the probe is properly installed, according to instructions in SECTION 2 I NSTALLATION, and the vacuum dryer is operating according to design.

3.2 SYSTEM START-UP

Verify wiring is according to instruction in SECTION 2.4. With all power off, place the power OFF/ON switch, SW1, to “ON.” Close and latch down 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 Mass Flow” rate in lb/hr units.

Upon a“cold” initial start-up of the RheoVacDR system, the probemay take severalminutes to giveaccurate readings. During this time the probe is transitioning to thermal equilibrium conditions under vacuum.

3.3 PORTABLE USB DATA STORAGE/Warranty Registration Instructions

Intek’s warranty program is stated at the front of the manual. To validate warranty:

A. Locate portable USB Data Storage Device in the main electronics enclosure (Figure 5). B. Grasp bracket and carefully remove portable USB Data Storage Device. C. E-mail all RheoVac DR instrument data to techsupport@intekflow. D. Replace portable USB Data Storage Device in the main electronics enclosure.

CAUTION - Do not attempt to use non-Intek approved USB flash drives with the RheoVac DR instrument. Your RheoVac DR instrument may not have the proper drivers installed for other USB flash drives. This may cause the RheoVac DR instrument to lock-up and require service.

3.4 DISPLAY

The RheoVac DR has a 2x20 alphanumeric scroll-through display that shows seven parameters for the probe pair. The display shows Air Mass Flow, Water Vapor Mass Flow, Total Mass Flow, Temperature, Pressure, Relative Saturation, or Actual Volume Flow (as well as Time/Date, Software Version, 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 RheoVac DR is configured for multiple probe pairs, the display will show all the probe serial numbers one set at a time, one for each probe pair. The numbers will be in order, from the lowest serial number to the highest, reading from left to right on the display. Example: 11621-1, 11621-2 and 11621-3.

- 12 -

3.5 COMMUNICATIONS

A typicalRheoVac DR instrument has an Ethernet port and two serial communications choices (RS-232 or RS-422). The ethernet port can communicate via Windows® network Modbus or OPC. Eight 420mA output signals for the probe pair are optional. Each process variable is a linear, fully temperature and pressure compensated value on any of these readable outputs. If supplied, 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. Communication with the

RheoVac unit using Intek supplied software is discussed in Appendix A and Appendix B of this manual. Note: Intek recommends using the network connection for all data transmissions and RheoVac communications.

3.6 DATA PROCESSING

A very important part of understanding your vacuum dryer system comes from evaluating the data that is created and stored by the RheoVac DR instrument. The ability to evaluate data has been greatly enhanced with the RheoVac DR 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 is invaluable when troubleshooting vacuum dryer problems. The column headings for each archived data file is seen in Table IV.

The importance of reviewing graphed data cannot be overstated. Reviewing data for normal operating conditions will greatly decrease the time need 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 This Excel add-in graphing utility, called RheoGraph, is an automated graphing macro that imports and graphs RheoVac DR data files. It is available on request.

The RheoGraph utility is contained in a self-extracting zip file called "RheoGraph.Rev...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 name 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. An example is shown of a graph made by RheoGraph showing air mass flow and water vapor mass flow.

3.7 CUSTOM SOFTWARE

Custom software may be developed by the user to receive and archive RheoVac DR 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 values. 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 probe surface and on the various terminal strip connections. Periodic checks with necessary cleaning should be performed to insure clean probes and terminals. The joints of the sensor leads should occasionally be inspected for corrosion or presence of moisture.

4.2 CALIBRATION

The RheoVac DR instrument is calibrated at the factory in a calibration system which replicates the vacuum dryer and vacuum line environment. The system is designed to calibrate the temperature, pressure, water vapor relative saturation and flow sensor under the gaseous fluid conditions found within the plant’s vacuum line.

In general, calibrations should be valid over a two year period if the probes are well maintained. Should the unit require re-ranging or recalibration, note the serial number of the RheoVac DR instrument and contact the factory concerning recalibration cost and turn around times. Refer to SECTION 5 CUSTOMER SERVICE of this manual for additional information. Contact Intek for calibration, monitoring service plans, instrument service agreements as well as other Intek products and services.

4.3 SPARE PARTS

It is sometimes advantageous to have a spare probe pair. Should a spare probe pair be desired, it can be ordered and stored for installation at any time. A spare probe will come with a parameter disk with calibration files that will need to be uploaded to the main electronics along with instructions to complete the update and install/replace the probe (see SECTION 4.4).

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

C Electronics: Slow blow 1A Wickmann fuse, part number 3721100041 or equivalent. C Probe: Slow blow 500 mA Wickmann fuse, part number 3720500041 or equivalent.

There are no other normally recommended spare components to stock.

To replace the fuse in the main electronics: locate the AC Power Input board (#01011-5 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 the socket 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.

To replace the fuse in the probe: locate the AC Power Input board (#01011-5 shown in Figure 5) in the lower right hand corner of the main electronics box, as above, to disable power to the probe. Gently pull the fuse from the socket and gently insert the replacement 500 mA fuse. Close the probe electronics lid.

- 16 -

Go to the main electronics enclosure and slide the power switch back to the “ON” position to enable power to the electronics and the probe(s). 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

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

, 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

File transfer can also be accomplished using Windows Explorer or Network Neighborhood

Specific network set-up at Intek may be required.

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 recalibration, or some other change in the RheoVac operating software is needed, this tab will be used. Do not use it until then. Instructions will be supplied at that time.

4. Retrieve Data accessed via Ethernet connection from the

The

RheoVac software creates a new data file each day. The file name is in the

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.

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 techsupport@intekflow.com.
