Hands-Off Testing The microturbines are tested in unattended cells according to an acceptance test proce- dure also known in the industry as a “green run.” Says the Principal Turbomachinery Engineer, “The ZonicBook helps us with two functions; it monitors the running engine for both the pass/fail and self-protection criteria, and it uses IOtech NDT relay boxes to safely and automatically shut down the engine if the vibration level should exceed preprogrammed limits. Many of the test cells run unattended during most of the test time, so automatically protecting the engine from damage recovers more than the cost of a single ZonicBook. In fact, over several years, each ZonicBook has saved at least one engine from a high-cost failure. “When we first started looking for equip- ment like this, I bought one of the earli- est model ZonicBooks, tested it with the eZ-TOMAS software, and I found that it did more than the other instruments I had worked with and new ones that I evaluated. However, over time, we came up with some ideas that would help us even more — to enable a higher quality process — and we passed them on to the IOtech software engineers. They are very supportive. We would make a request for a new feature, and they would provide it in a couple of weeks, or sometimes just in hours. We are confident now that we can run the tests in an unattended cell because of all these improvements and upgrades. We are very pleased because we got the product we needed when no one else had it.” ZonicBook/618E Vibration analysis and monitoring has never been easier than with the ZonicBook/618E and eZ-Series analysis and monitoring software. The ZonicBook leverages 30+ years of experience providing vibration measurement solutions. The ZonicBook hardware is the signal condition- ing and acquisition engine, while the eZ-Series software in the PC defines the specific analysis and monitoring features of the system. The ZonicBook’s architecture makes expansion beyond the eight built-in channels less expensive than other suppliers. You can expand the ZonicBook in 8-channel increments up to 56 channels, and each additional 8 channels are approximately one third the cost of the first 8 channels. All channels in a ZonicBook system are measured synchronously, providing 1 degree phase matching between channels. Features • 8 dynamic input channels, expandable up to 56 chan- nels • 4 tachometer channels for rotational measurements • High-speed Ethernet connec- tion to the PC for continuous recording • Four eZ-Series software packages address a wide variety of vibration monitoring and analysis applications • TEDS support for accelerometers Software Overview Four software packages are available for the ZonicBook, each tailored to a particular vibration measurement and analysis appli- cation. Choose the package that suits your application now, and upgrade to additional packages as your requirements evolve. • eZ-Analyst provides real-time multi- channel vibration analysis, including overlay of previously acquired data while acquiring new data, strip charts of the throughput data files, cross channel analy- sis, and direct export to the most popular MODAL analysis packages, ME Scope and Star Modal. • eZ-TOMAS provides on-line vibration recordings, limit checking, storage, and analysis of rotating machinery. Order track, Waterfall, Orbit, Polar, Bode, Spectrum, and Trend displays show machine startup or shutdown events, as well as diagnose long-term changes in machine health. • eZ-Balance is used to balance rotating machinery with up to seven planes. A balance toolkit, including Split Weight calculations, supports the balance process. The balance vectors are displayed on a po- lar plot so the user has a visual indication of the improvement. Time and spectrum plots show detailed vibration measure- ment during the balance process. • eZ-NDT package is exclusively used in production applications to determine the quality of composite-metal products at production rates of 1 part per second. The ZonicBook/618E with eZ-Series software and your PC makes a real-time, portable vibration analysis monitoring system eZ-Analyst adds real-time continuous and tran- sient data acquisition in the time, frequency, or order domain View Time-Domain, Spectrum, Waterfall, and Trend simultaneously on one screen with eZ-TOMAS eZ-Analyst, eZ-Balance, eZ-NDT, eZ-TOMAS, ZonicBook, ZonicBook/618E, and Out-of-the-Box are the property of IOtech.
