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.
PAGE 4
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.
PAGE 5
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).
PAGE 6
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.
PAGE 7
# 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.
PAGE 8
2.3 2.4 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.

Ñ Ò Ó Ô 2.5 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. 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.

4. Network Connection: The Ethernet connection at JP1 is an RJ-45 style jack. A 10 foot Ethernet Cat 5 crossover cable is supplied with the unit. B. 1. 2. 3. 4. 5. Distribution Box (see Figure 6) Connect the RS-485 wires (blue, white and shield) and 24Vdc power (red and black) from the main processor unit. Install ½” liquid-tight conduit between the distribution enclosure and the probes unless ½” rigid conduit is used for long distance runs. Use a minimum of 6 feet of liquid tight at the probes.
PAGE 13
C. Probe - . . CAUTION - Do not cross thread connection. The 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 RS485 cable once it is run from the Distribution Box to the probe. A separate instruction sheet comes with the connector, showing the wiring connections. D.

E. 1. 2. 3. 4. 5. 6. 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.
PAGE 16
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.
PAGE 17
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.

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 .

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.

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.
PAGE 26
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.
