P—IntroductionMany years of experience and innovation in the design and successful application of continuous chemical analyzers has been combined with the latest electronics and production technologies to produce the Navigator 600 Series of analyzers from ABB.Developed as fully continuous analyzers offering wide dynamic ranging, the Navigator 600 Series incorporates greater simplicity and functionality than ever before. Based on colorimetric techniques, they feature a liquid handling section carefully designed to reduce routine maintenance. Utilizing powerful electronics, advanced features such as automatic calibration, continuous sample analysis and programmable multi-stream switching ensure accurate and simple measurement of silica.Process data, as well as the content of alarm and audit logs, can be saved to a removable SD card in binary and comma-delimited formats for record keeping and analysis using ABB’s DataManager data analysis software package.A very low cost of ownership has been achieved by reducing the reagent consumption and simplifying the maintenance requirements.The size of the instrument has been reduced to a compact, ergonomically-designed, wall-mounted case thus providing a very small footprint.—ApplicationsTypical applications for the Navigator 600 Silica are:• Demineralization Plants for Power and Process Industries. –Monitoring the outlet of the anion and mixed beds forsilica breakthrough, providing indication of bedexhaustion and final water quality.• Boiler Systems.–Monitoring boiler drum water, providing information on the contamination levels in the boiler.–Monitoring silica carryover in saturated steam thusprotecting turbine blades from potentially excessivescale build up.–Monitoring the exhaustion of ion exchangers in aCondensate Polishing Plant.—OperationGeneralThe Navigator 600 Silica is an on-line analyzer, designed to provide continuous monitoring of silica concentration utilizing a standard colorimetric analysis principle.Liquid handlingThe chemistry employed for silica measurement is the industry standard Molybdenum Blue reaction. Sample and reagents are drawn into the instrument by two multichannel peristaltic pumps. These are designed and constructed to ensure only simple yearly maintenance is required. The reagents are added to the sample in a temperature-controlled reaction block and the fully reacted sample is then passed through an in-line measuring cuvette.The optical measuring system enables accurate detection of silica concentrations from 0 to 5000 ppb.The instrument includes a manual sampling facility thatenables the analysis of grab samples.Figure 1 Liquid Handling SectionSolution replacementContinuousReagents 3 monthsCalibration Standard 3 monthsCleaning Solution 3 months4NAVIGATOR 600 SILICA SILICA ANALYZER | DS/NAV6S-EN REV. P—ElectronicsThe main electronic transmitter consists of a display and key pad accessible from the front of the unit. Indication of all parameters is provided by a large backlit LCD display that is easy to read in all light conditions. Under normal operating conditions, measured values are displayed; programming data is displayed during set-up and also on demand. Units and range of measurement, alarm values and standard solution values are examples of the many programmable functions.Keeping simplicity of operation at the forefront of design, six fingertip-operated tactile membrane switches control local operation of the analyzer and provide easy access to all parameters.The Navigator 600 Silica is provided with 4 dedicated relays, 6 user-programmable relays and 6 current outputs as standard.Profibus DP V1.0 is available as an option.Figure 2Display and keypadFigure 3 Chart view display—Ethernet communicationsThe Navigator 600 Silica can provide 10BaseT Ethernet communications via a standard RJ45 connector and usesindustry-standard protocols TCP /IP, FTP and HTTP. The use of standard protocols enables easy connection into existing PC networks.—Data file access via FTP (File Transfer Protocol)The Navigator 600 Silica features FTP server functionality. The FTP server in the analyzer is used to access its file system from a remote station on a network. This requires an FTP client on the host PC. Both MS-DOS® and Microsoft® Internet Explorer version 5.5 or later can be used as an FTP client.• Using a standard web-browser or other FTP client, data files contained within the analyzer’s memory or memory card can be accessed remotely and transferred to a PC or network drive.• Four individual FTP users’ names and passwords can be programmed into the Navigator 600 Silica. An access level can be configured for each user.• All FTP log-on activity is recorded in the audit log of the instrument.• Using ABB’s data file transfer scheduler program, data files from multiple instruments can be backed-up automatically to a PC or network drive for long-term storage, ensuring the security of valuable process data and minimizing the operator intervention required.FTP clientEthernetNavigator 600 Silica(FTP server)Navigator 600 Silica(FTP server)5NAVIGATOR 600 SILICA SILICA ANALYZER | DS/NAV6S-EN REV. P —Embedded web serverThe Navigator 600 Silica has an embedded web-server that provides access to web pages created within the instrument. The use of HTTP (Hyper Text Transfer Protocol) enables standard web browsers to view these pages.• Accessible through the web pages are the current display of the analyzer, detailed information on stream values,reagent and solution levels, measurement status and other key information.• The audit and alarm logs stored in the Navigator 600 Silica’s internal buffer memory and memory card can be viewed on the web pages.• Operator messages can be entered via the web server, enabling comments to be logged to the instrument.• The web pages and the information they contain are refreshed regularly, enabling them to be used as a supervision tool.• The analyzer’s configuration can be selected from an existing configuration in the internal memory or a new configuration file transferred to the instrument via FTP.• The analyzer’s real-time clock can be set via the webserver. Alternatively, the clocks of multiple analyzers can be synchronized using ABB’s File Transfer Schedulersoftware.—Email notificationVia the Navigator 600 Silica’s built-in SMTP client, the analyzer is able to email notification of important events. Emailstriggered from alarms or other critical events can be sent to multiple recipients. The analyzer can also be programmed to email reports of the current measurement status or other parameters at specific times during the day.—ProfibusThe Navigator 600 Silica can be equipped (option) with Profibus DP V1.0 to enable full communications and control integration with distributed control systems.6NAVIGATOR 600 SILICA SILICA ANALYZER | DS/NAV6S-EN REV. P—MaintenanceThe analyzer has been designed to maximize on-lineavailability by reducing routine maintenance to a minimum.Yearly maintenance consists of simply replacing pumpcapstans and pump tube assemblies, an operation that cantake as little as five minutes.Figure 4 Simple to replace pump tube assemblesFully automatic calibration, zeroing and cleaning functions enable the analyzer to keep operational with minimal manual intervention. A predictive alarm alerts the user to reagent solution replacement being required. The cleaning and calibration solutions have a sensor to detect when replacement is necessary.—OptionsMulti-stream facilityA fully programmable multi-stream option is available on the Navigator 600 Silica on-line analyzer, providing up to six-stream capability including individual current output and visual indication as well as user-programmable stream sequencing.The analyzers are designed to be easily upgradeable in thefield to two, four or six streams.Figure 5 Six stream display7 NAVIGATOR 600 SILICA SILICA ANALYZER | DS/NAV6S-EN REV.
