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.
PAGE 4
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.

SECTION 2 — INSTALLATION 2.1 INSTALLATION These instructions are general guidelines 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.

2.2.2 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.
PAGE 9
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.
PAGE 10
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.
PAGE 11
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 Intek upon 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.
PAGE 12
C. Transmitter Box (optional, See Figure 8) - For driving eight (8) remote 4-20 mA analog signals from one RS-485 input port. Note: Intek recommends using the network connection for all data transmissions and RheoVac communications. 1. Connect the RS-485 communications/power cable from the distribution box (RS-485: white and blue wires; 24Vdc power: red and black wires). 2. Connect up to eight (8) signal wire pairs to the indicated terminals for isolated 4-20mA outputs. 3.
PAGE 13
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.
PAGE 14
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.
PAGE 15
3.5 COMMUNICATIONS A typical RheoVac 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.
PAGE 16
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.
PAGE 17
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 .
PAGE 18
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.
PAGE 19
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. 4.4 TROUBLESHOOTING Table VI provides a guide for plant personnel to identify causes of problems and determine appropriate actions to resolve problems observed. If problems are encountered and factory assistance is desired, please contact the factory.
PAGE 20
When using the RheoVac DR software on a PC, the software may give you a “Communication Message.” Use the information in TABLE VII and TABLE VIII to determine the source of this problem and appropriate action. TABLE VII. Troubleshooting Guide (serial connection software communication issues) OBSERVATION PROBA BLE CAUSE ACTION Appears the first time the application was executed 1. Instrument not connected to the software defaulted serial port 2.
PAGE 21
4.5 HARDWARE AND SOFTWARE MODIFICATIONS AND UPGRADES Note: The workgroup setting of the identification tab in Network Neighborhood Properties must be set to WORKGROUP which is the instrument default setting. A Cat5 crossover network cable is required for proper Ethernet network communication to the RheoVac DR instrument. Normally, updating the main software residing on the RheoVac DR should be done at the factory.

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 25
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.

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.
