It provides rich information about machinery health for both operations and maintenance personnel. Overall vibration, PeakVue, and temperature readings can be easily integrated into any control system or plant historian while diagnostic data can be displayed by AMS Suite: Intelligent Device Manager or any EDDL compliant host. For advanced diagnostics, high resolution data can be delivered to AMS Suite: Machinery Health Manager for trending and analysis. The AMS 9420 delivers complete vibration information, including high resolution spectra and waveform, over a self-organizing wireless network for use by operations and maintenance personnel. Cost-Effective, Reliable Monitoring The AMS 9420 extends vibration monitoring to an entire array of new applications. While appropriate for most vibration monitoring tasks, it is especially well suited for hard-to-reach locations, such as cooling towers, pumping stations, remote equipment, and hazardous areas. In general, the AMS 9420 provides an excellent solution for any application that might otherwise involve extensive engineering, cabling, or installation costs. Advanced electronics deliver a high level of accuracy, while the IEC-approved WirelessHART standard delivers exceptional reliability. AMS 9420 Wireless Vibration Transmitter July 2017 Overall Condition in the Control Room The AMS 9420 delivers information about the overall health of rotating assets directly to the control room via Modbus or OPC. Overall vibration data is a good indicator of shaft problems such as imbalance, misalignment, or mechanical looseness. In contrast, the PeakVue reading provides a reliable measure of impacting on the machine. As the PeakVue level increases, it provides direct indication of a developing problem, such as improper lubrication, bearing fault, or gear defect. Process induced faults, such as pump cavitation, are detected by an increase in both the overall vibration and PeakVue readings. Asset Dashboard at your Fingertips AMS Device Manager generates an asset dashboard based on the output of the AMS 9420. This intuitive interface displays the health of the sensor, the transmitter, and the production asset being monitored – extending the benefits of PlantWeb® to WirelessHART devices. AMS Device Manager uses EDDL technology to create an asset dashboard with clear indication of device and asset status. PeakVue Technology ™ Focus on Impacting for Better Results Traditionally, vibration data has not been routed to the control room because it required specialized training — and frequently specialized tools — to extract any information from the data. Emerson’s unique PeakVue technology cuts through the complexity of machinery analysis to provide a simple, reliable indication of equipment health via a single trend. PeakVue filters out traditional vibration signals to focus exclusively on impacting, a much better indicator of overall asset health on pumps, fans, motors, or any other type of gearbox or rolling element bearing machine. PeakVue measurements are easy to interpret and are based on a concept called The Rule of Tens. For properly installed and well-lubricated machinery that is not impacting, the PeakVue measurement is at or close to zero. If a problem develops, the PeakVue measurement climbs to 10g. A measurement of 20g indicates a serious problem in www.emerson.com/ams the bearing, even though overall vibration levels might not indicate the same. When the measurement exceeds 50g, failure is imminent. State Bearing Life Remaining Vibration (in/sec) PeakVue (g’s) New Full 0.15 0 1 <20% 0.15 10 2 <10% 0.15 20 3 <5% 0.16 30 4 <1% 0.18 40 Failure 0% >0.45 >50+ Typical values for a Horizontal Pump, direct coupled, with machine speed of 600-60000 RPM. PeakVue data provides earlier indication of developing faults in rolling element bearings and gearboxes. 2 AMS 9420 Wireless Vibration Transmitter Diagnostic Data to the Maintenance Office AMS Machinery Manager automatically communicates detailed diagnostic data to the maintenance office, including overall values, energy bands, high resolution spectra, and waveforms. Once stored in the AMS Machinery Manager database, these measurements deliver the same diagnostic value as comparable readings collected using Emerson’s industry- leading AMS 2140 Machinery Health Analyzer. AMS Machinery Manager provides advanced analytical tools to trend vibration levels, generate alerts, and diagnose developing faults. Information Available When You Need It There are now three ways to collect high-resolution spectra or waveforms: 1) Time-based: Collect readings automatically on a scheduled basis, i.e. once every two weeks. 2) On-alert: Collect readings automatically whenever an alert is registered based on either the overall vibration or the PeakVue impacting.1 3) On-demand: Manually initiate a reading at any point when current diagnostic data is required. This allows you to quickly and easily access current health information about your rotating assets without leaving your desk.1 July 2017 Flexible Configuration Options The Power to Get Things Done There are two power options for the AMS 9420. For a truly wireless experience, utilize the SmartPower™ Module. Based on the low power output defined by the WirelessHART standard, the AMS 9420 can achieve an operating life of up to 4 years when using the Power Save option. An operating life of two to three years can be achieved when using the default settings (update rate set to 60 minutes). For faster update rates, the external DC-powered terminal block is recommended. This option provides virtually unlimited operation, even at the minimum update rate of once per minute. Local Indication and Verification The optional LCD display provides a local read-out of sensor values and transmitter diagnostics to streamline commissioning and troubleshooting at the device. Local indication of vibration measurements and diagnostics also provides accurate, real-time verification of operating conditions. The LCD display can be rotated to facilitate easy viewing, regardless of the orientation of the transmitter. Plan and Manage Wireless Networks The AMS Wireless SNAP-ON™ application is a revolutionary tool that enables you to both plan and manage your wireless network. Starting with a scale drawing of the plant, utilize simple click-and-drag functionality to position the gateways and wireless devices. Then the AMS Wireless SNAP-ON application will compare the plan to industry best practices. Recommendations will help you quickly develop a reliable wireless network. After the devices are installed, the AMS Wireless SNAP-ON application will help you manage the network, providing a graphical overview of the communication paths and network health. AMS Machinery Manager provides advanced analytical tools to trend vibration levels, generate alerts, and diagnose developing faults. 1 Requires AMS Machinery Manager version 5.61 or higher. www.emerson.com/ams 3 AMS 9420 Wireless Vibration Transmitter Wireless Architecture Overview Ultimate Simplicity Built on the IEC 62591 (WirelessHART) industrial standard, Emerson’s wireless network is completely self-organizing. There is no need to configure communication paths because the Smart Wireless Gateway manages this automatically – including adapting to changing environments. Once the network is established, new devices can be added at any time. Conversely, even if a device is de-commissioned, data reporting from other devices continues uninterrupted over other established paths. Easy Installation The AMS 9420, like all Emerson’s Smart Wireless transmitters, is simple to install. As soon as power is applied to the device, it will automatically establish communication with neighboring wireless devices, establish a path to the Gateway, and begin reporting. Each transmitter also has the ability to function as a repeater, relaying data from other devices to extend the network across virtually any size facility or industrial campus. Network Stability The Smart Wireless Gateway connects the wireless network with the host system and data applications like AMS Suite. The Gateway manages all aspects of the network: executing scheduled readings and accommodating requests for on- demand acquisitions. The Gateway configures the network to minimize power consumption and ensure network stability, while maintaining data reliability well above 99%. July 2017 Best-in-Class Security Emerson’s multi-layered approach to wireless network security builds on the IEC 62591 standard to ensure that your data stays protected – no matter what. Authentication and verification make certain that only authorized devices can join the network, while 128-bit encryption shields your information. Channel hopping maintains operation, even in challenging environments. Emerson’s Complete Smart Wireless Solution Emerson has a complete portfolio of Smart Wireless transmitters for many applications, including temperature, pressure, flow, and level. In addition, the Smart Wireless THUM™ Adapter can enable any HART device to wirelessly transmit measurement and diagnostic information. Emerson wireless devices can be accessed and maintained remotely using the same tools and software as wired devices, leveraging existing practices, training, and maintenance procedures. AMS Machinery Manager DeltaV / Ovation AMS Machinery Manager Legacy System At the heart of Emerson’s Smart Wireless solution is the selforganizing network, featuring tight security, infinite configurability, and data reliability that rivals wired systems. Seamless Integration to Host Systems Easily configure and broadcast measurements to Emerson’s DeltaV™ and Ovation™ digital automation systems; use Ethernet IP™ to connect to Allen-Bradley® controllers; or apply Modbus or OPC to report data back to most other automation systems and/or data historians. The AMS Wireless SNAP-ON application graphically displays your wireless network. www.emerson.com/ams 4 AMS 9420 Wireless Vibration Transmitter July 2017 Analyze Data in AMS Machinery Manager High Resolution Spectrum Vibration data from the AMS 9420 can be stored and analyzed in AMS Machinery Manager. The Data Import module provides easy data mapping using simple drag-and-drop commands. AMS Machinery Manager combines predictive techniques with comprehensive analysis tools for an accurate assessment of the machinery health in your facility. The first compression technique is FFT analysis, which transforms the vibration waveform into a frequency spectrum (shown below). This spectrum not only reduces the file size by over 60%, it also presents the frequency information in a more readable format. The smaller data set accelerates responsiveness of the system while reducing power consumption. Detailed Reliability Data Overall vibration indicates when a machine is running rough, while the level of impacting detected by PeakVue signal processing provides the operator with an indication about the presence and severity of a serious defect such as underlubrication, bearing faults, gear defects, and pump cavitation. Furthermore, once a machine has been flagged, detailed data can be analyzed by a vibration specialist to verify the exact nature of the fault. With the advanced diagnostics in the AMS 9420, you have easy access to all of this critical information. High Resolution Waveform The vibration waveform (shown below) is the basis for all other vibration measurements performed by the AMS 9420. Each waveform is a complex data set of thousands of samples, collected over several seconds of machine operation. While the acceleration waveform can be helpful in some applications, the PeakVue waveform is indispensable for diagnosing developing bearing and gear defects. Because of their large size, however, waveforms tend to be collected less frequently. Emerson’s Smart Wireless solution employs several data compression techniques to extract the information while facilitating easier transmission over the network. The elevated peaks in this high resolution spectrum provide a clear indication of mechanical looseness on the machine. Thumbnail Spectrum The thumbnail spectrum is derived from the same waveform data. It contains the same frequency and amplitude information as the high resolution spectrum, but the data set has been compressed by an additional 98%. Now it is small enough to transfer over the network in less than a second. The elevated peaks are still clearly visible in the thumbnail spectrum and indicate the presence of mechanical looseness. The acceleration waveform contains raw vibration data that allows you to diagnose the health of the asset. www.emerson.com/ams 5 AMS 9420 Wireless Vibration Transmitter July 2017 Energy Bands As a final data compression technique, the AMS 9420 divides the spectrum into three predetermined energy bands (as shown below). It then calculates the vibration energy within each energy band and passes these values to AMS Machinery Manager for trending and alerts. Band Fault Types Range 1 Rotor Vibration: Imbalance, misalignment (also defects on belt drives) 2–65 Hz 2 Rotor Harmonics: Looseness, electrical faults, blade and vane pass 65–300 Hz 3 High Frequency: Bearing and gear defects, lubrication and cavitation 300–1000 Hz Energy bands with frequency ranges. Optimized for a 4-pole motor running between 1500 and 1800 RPM. Note: bands are fixed. The trend of overall vibration suggests that machine health is deteriorating but without any indication as to the root cause. The trend of the high frequency energy band provides further insight, which can be confirmed by examining the thumbnail spectra. By trending the values in AMS Machinery Manager and comparing them to appropriate alert levels, it is possible to set up a system of intelligent alerts that not only inform you when the machine condition is deteriorating, but also provide information about the underlying cause of the problem. The figure illustrates how vibration data can be used to detect and diagnose a developing fault. Based on the increase in overall vibration (black line), an alert would flag the machine as having a potential fault – but with no indication at all about the nature or severity of the fault. The trend of the three energy bands shows that the readings for rotor vibration (green) and rotor harmonics (blue) are stable, while the readings for high frequency vibration (red) have increased sharply. This would trigger a special alert for the rotating equipment specialist in AMS Machinery Manager. By dividing the spectrum into energy bands, we can isolate frequencies associated with different categories of faults. www.emerson.com/ams Examination of the thumbnail spectra (shown above the trend) confirms that the fault is high frequency in nature. On-demand acquisition of the PeakVue spectrum and waveform then provides conclusive insight into the specific nature of the fault as well as its severity. Using the advanced diagnostics in the AMS 9420 and AMS Machinery Manager, maintenance personnel can often address and resolve an issue without it ever registering as an alert in the control room. 6 AMS 9420 Wireless Vibration Transmitter July 2017 Functional Specifications Inputs Accelerometer 1 DC Bias Range: 2 - 3 Vdc DC Input Range: 0 - 5 Vdc AC Input Range: +/- 80 g’s peak (784 m/s2 peak) Accelerometer 2 DC Bias Range: 2 - 3 Vdc DC Input Range: 0 - 5 Vdc AC Input Range: +/- 80 g’s peak (784 m/s2 peak) Temperature DC Input Range: -30° to + 121°C (-22°F to 250°F ) Standard Outputs Machinery Health Values Velocity overall (1 or 2 sensors) PeakVue overall (1 or 2 sensors) Temperature (1 sensor only) Transmitter Health Values Ambient temperature Supply voltage Sensor bias voltage (1 or 2 sensors) Multiple internal alerts indicate the status of device health Advanced Diagnostic Outputs (optional , requires link through an Emerson Smart Wireless gateway device) Energy bands Rotor vibration (2 - 65 Hz) Rotor harmonics (65 - 300 Hz) High Frequency (300 - 1,000 Hz) Thumbnail Spectrum Fmax: 150, 300, 600, or 1,000 Hz High Resolution Vibration Spectrum Fmax: 1,000 Hz Resolution: 4002, 800 or 1,600 lines Snapshot or Averaged (4 readings) High Resolution Vibration Waveform All measurements based on high resolution waveform with 4,096 points High Resolution PeakVue Spectrum Bandwidth: 1,000 - 20,000 Hz Fmax: 1,000 Hz Resolution: 1,600 lines Snapshot of impacting on machine High Resolution PeakVue Waveform Sampled at 51,200 Hz; High resolution with 4,096 points Display Units English, metric or SI Local Display The optional five-digit integral LCD display provides readout of HART parameters in engineering units (°F, °C, in/sec, mm/sec, g’s and m/s2).

As any plant manager will tell you, you can’t improve something if you can’t measure it. Improved access to information provides the opportunity to reduce operating costs while improving quality, throughput, and availability. Add to that the expanding requirement to certify compliance with new environmental and safety standards. This all points to the need for increased monitoring, yet many managers still believe that the costs outweigh the benefits. With wired systems, that may have been the case; however, wireless networks remove traditional barriers and redefine the cost equation. A wireless network can substantially reduce engineering, material, and implementation costs, and those cost savings are just the beginning. Imagine what you can do with the additional information. Wireless technology can reduce – if not eliminate – the “blind spots” in your plant, while empowering mobile workers by providing needed information. The AMS 9420 provides predictive diagnostics for your essential production assets from virtually any location. The result is increased process uptime, improved consistency, and reduced risk of abnormal situations. As more and more plants are turning to wireless solutions, the question is “Are You Wireless?”. An AMS 9420 is an easy addition to any existing wireless network. ©2017, Emerson. All rights reserved.
