2 VM600 Series Overview The new generation of system for machinery monitoring from Vibro-Meter is based upon 50 years of experience in the design and manufacture of sensors and monitoring systems for industrial and aerospace machinery. We have installed thousands of channels of machinery protection and condition monitoring worldwide, and have achieved an enviable reputation for reliability, innovation and expertise. The new Vibro-Meter VM600 represents the true integration of machinery protection monitoring and advanced condition/performance monitoring within a single system, without compromising any of these objectives. While much of this system s benchmark setting capability is attributed to state of the art digital technology and modern surface mount production techniques, the system philosophy builds upon the knowledge and experience gained with our highly successful MMS and System 501X product ranges. In addition feedback from our extensive customer base has, and continues to be, a key element in all our product developments to ensure that VM600 is not only the most advanced monitoring system available, but is also the most suited to our present and future customers needs. The design takes into account all different requirements for such systems from small, stand-alone protection systems to large networked installations including condition and performance monitoring. The main aim has been to utilize as few modules as possible, which has resulted in a unique design whereby only one type of card is required for all types of protection monitoring. For applications requiring FFT based condition monitoring capability a second card is provided. Both cards reflect Vibro-Meter s philosophy of providing the most advanced technical solutions in the most cost effective manner. The VM600 Series is designed to be totally flexible both in terms of physical and system configuration. In addition the use of VME hardware, open architecture and industry standard communication protocols for data exchange, the system is truly modular and scaleable. The system consists of a standard VME chassis (19, 6U) with four types of processing/communication cards: MPC4 - Machinery Protection Card AMC8 Analogue Monitoring Card CPU-M card for configuration/display and network communications to other systems CMC16 Condition Monitoring Card The flexibility of the VM600 Series allows various configurations - the system can be operated in a stand-alone mode for machine protection with or without local displays, or remotely (via PC, Control System or Workstation) as part of a comprehensive combined protection and condition/performance monitoring system.

3 VM600 MACHINERY PROTECTION SYSTEM MPC4 Machinery Protection and Monitoring Module Unlike competitor systems only one type of VM600 module, the standard MPC4 card, is used for all protection monitoring parameters, whether this is acceleration, velocity, displacement, thrust, dynamic pressure etc. and is simply software configured to the task. No hardware configuration is required. This ensures reduced spare-part requirements, shortened delivery times, increased flexibility as well as simplifying the training of operators. The MPC4 Machinery Protection Card is a digital card designed for monitoring and protection of industrial rotating machinery. Each card has 4 dynamic channels and 2 speed or phase reference channels. The dynamic channels can be connected to all types of vibration transducer including proximity sensors, accelerometers, velocity sensors etc. or speed probes (proximity, magnetic or optical). The MPC4 may be configured to measure: Absolute vibration (accelerometer, velocity sensor) Relative shaft vibration (radial measurements) Absolute shaft vibration (combination accelerometer/proximity sensor) Shaft position (thrust), axial or radial S max value Shaft eccentricity Dynamic pressure Absolute expansion Differential expansion Casing expansion Displacement Air gap Static pressure, temperature etc. The monitoring functions are: Broad-band vibration/dynamic pressure monitoring (digital HP/LP filter cut-off settings, slopes individually configurable up to 60 db/octave) Narrow band (tracking filter) monitoring for variable speed machinery including amplitude and phase of 1X, 2X, 3X, 4X, and amplitude of NOT 1X, 1/2X and 1/3X components. OK sensor/line checking: A built-in OK system check provides continuous monitoring of the signal coming from the sensor and conditioner to check for broken lines or faulty components etc. Programmable ALARM and TRIP limits (each with an upper and lower limit threshold). Hysteresis and time delays are programmable. VM600 Overview Page 3 of 27

4 Other features: Industrial & Marine Division Real-time data processing Built-in power supply for the majority of sensor systems Self-test (BITE) Adaptive monitoring (alarm levels adapted to, for example machine speed) Direct trip multiply and danger bypass (on a per card basis NOT per rack) Hot-swap of modules. Modules can be replaced without losing monitoring of the other cards and configuration data is automatically downloaded to the card. Up to 12 MPC4 cards fit in one chassis, i.e. 48 dynamic signals and 24 speed or phase reference signals can be monitored in a single 19 rack. This gives the user the scope to monitor multiple machines from a single rack. The MPC4 card has 6 BNC connectors on the front, 4 for dynamic signals and 2 for speed/phase reference, to provide buffered raw signal output to portable data loggers or other analysis equipment. These signals are also available at the rear of the rack. And in both cases are true one to one representations of the raw signal input. The card is inserted from the front of the chassis and plugs into the VME backplane and bus, and at the same time it connects to the rear-mounted IOC4T input/output card where field screw terminals or connectors are placed. The IOC4T card includes 4 relay outputs which can be configured for alarm, trip and OK as well as system status parameters. Relay operation can be further configured to use up to 8 basic logical and voting combinations and 4 advanced logical combinations. Additional relays can be provided via the optional RLCcard which contains a further 16 relays. It should be noted that RLC cards can be fitted in any of 6 dedicated slots on the rear of the rack, or alternatively in any slot unused by IOC modules, this flexibility ensures that no restriction is imposed on the number of channels that can be monitored from a single rack. Connection to the IOC4T and to additional relay cards is by screw terminal, all accessed from the rear of the rack. There are various possibilities to configure the MPC4, using our VM600 MPS software, available under Windows NT, XP, 98, 2000, 2003 or UNIX and Linux operating systems: Direct RS232 serial connection to each card via a laptop, notebook, industrial PC or flat-panel PC. Direct One-shot configuration of the whole rack through the RS232 serial connection of the CPU-M, if present, via a laptop, notebook, industrial PC or flatpanel PC. Networked One Shot configuration via the CPU-M connected to an Ethernet network, and controlled by Workstation, PC, Control Systems etc. locally or from a remote site In all configurations the MPC4 is individually and totally self-running for machine protection and is not dependent upon either CPU-M or VME bus. VM600 Overview Page 4 of 27

5 CPU-M Configuration and Communication Module The CPU-M brings the following functionality to the standard VM600: One-Shot configuration of all VM600 cards using a direct RS232 serial connection from an external PC (laptop, notebook, industrial PC or flat-panel PC) running VM600 MPS software One-Shot configuration of all VM600 cards from a networked PC Host running VM600 MPS software Provision of local micro-display for visualization of monitor outputs and alarm limits External communication interfaces with third party devices such as DCS/PCS. Up to 3 Serial connections (RS232/422/485) can be accommodated, and up to 2 Ethernet connections. These can be configured for redundant comms. links where necessary Industry standard protocols are provided including Modbus RTU and Modbus/TCP. Automatic download of the configuration if a MPC4 or AMC8 card is replaced The CPU-M has an extended operating temperature range of -20 C to +70 C. System Architecture As shown below, the VM600 MPS system can be operated as a stand-alone unit configured from a notebook PC or can be networked and integrated with other control and information systems using industry standard protocols. Configuration and display can be provided from workstations running either WINDOWS, UNIX or Linux operating systems. In both configurations the Machinery Protection function is not dependent on any communication network or the VME bus for normal machinery protection functions. The card is selfrunning with analogue and relay outputs. ETHERNET RS485 / modbus ETHERNET / TCP-IPP (MPS1, MPS2, CMS1, ETHERNET / TCP-IP (MPS1, RS232 / VT100 RS232 / PPP (Config.

7 VM600 Machinery Protection and Condition Monitoring CMC 16 - CONDITION MONITORING CARD The CMC 16 is the 16 channel Condition Monitoring Card used within the VM600 VME rack to acquire, analyze and transmit vibration, process and phase reference data to a PC Host running VM600 CMS Software. The CMC 16, with it s associated IOC 16T input conditioning card, the standard communication route between CMC and PC is via the VMEbus, CPU-M and Ethernet controller. Up to 12 CMC 16 cards can be accommodated within a VM600 rack, assuming that slots are not already utilized by MPC4 or AMC8 modules, thereby providing up to 192 channels of condition monitoring in a single monitoring rack. While there is no limit to the number of racks that can be connected in a system, we recommend that no more than 200 CMC channels should be connected to any PC Host, as typically large volumes of data is also acquired over digital links from third party systems. This limit is however continually increasing as PC performance and particularly disk access times improve. For bigger systems multiple networked PC Hosts provides an optimal solution. HARDWARE SPECIFICATION 16 dynamic input channels, the first 4 of which can be pre-selected as either vibration or tacho/phase reference. For every channel, the signal conditioning is done by dedicated circuitry implemented on the IOC 16T. Data is sampled and processed in parallel. Input signals can be externally wired via screw terminal strips on the rear of the IOC 16T card, or where the raw signals are already wired to MPC4 cards, and then they are available from the VM600 RAWBUS without need for any additional wiring. Tacho/phase reference signals likewise can be wired to the screw terminals of the IOC 16T or obtained directly from the VM600 TACHOBUS The CMC 16 communicates with the CPU-M across the VMEbus. Communication between the CPU and the PC Host running VM600 CMS software is achieved via an Ethernet TCP/IP connection. CMC 16 and IOC 16T can be Hot Inserted and, providing that a CPU-M is installed and that the address is set correctly then the cards will be automatically configured on insertion.

The frequency analysis is by-passed. Alarm/Alert detection. - The band status defines the channel status. Analog resolution & Compression ratio. VM600 Overview Page 10 of 27

11 OPERATING MODES Background Mode The background mode is the default mode of the CMC 16. In this mode 1024 time domain samples are processed to construct 400 line spectra, for band extraction. In background mode the CMC 16 performs the following tasks: Event detection. - The band status (normal/alert/alarm) is checked. Interval detection - Time is checked against configured logging intervals. Transient detection. - Tacho and channel status is checked as the basis for initiation of transient modes. Real-time data transmission. - Real time band data, waveforms, spectra and orbits are transmitted to the PC. Trend data transmission - All band data is transmitted to the PC based upon the; configured logging rate for that channel, alarm status, analog resolution or whether an event has been detected. Long term trend handling - Band data is averaged over periods configurable up to 12 hours in order to construct long term trends covering weeks, months and years. Status history - Logs of band and channel events are maintained. Scheduled Mode During steady state operation (i.e. not in transient mode), high resolution waveforms, spectra and orbits are collected and sent to the PC at intervals defined in the configuration. The waveforms, spectra and orbits acquired and processed in this mode are independent of those extracted under the background mode. Transient mode In transient mode, the CMC 16 provides the following tasks: Event detection. - The band status (normal / alert / alarm) are checked. Interval detection - Time and speed are checked against configured logging intervals. Real-time data transmission. - Real time band data, waveforms, spectra and orbits are transmitted to the PC. Transient trend data transmission - All band data is transmitted to the PC based upon the configured logging rate ( T or RPM) for that channel. Trend data transmission - All band data is transmitted to the PC based upon the configured logging rate ( T or RPM) for that channel, or whether an event has been detected. Cascade data transmission Up to 100 spectra of 400 lines are transmitted to the PC based upon the configured logging rate ( T or RPM) for that channel. Status history - Band and channel events are logged. VM600 Overview Page 11 of 27

12 Oscilloscope mode This mode is used to record on request, time series of longer duration than those available in scheduled mode. A typical application of this mode is the capture of complete waveforms during transients. There is no interruption to compute the FFTs. On receipt of a trigger message from the PC, due, for example, to a user initiated request from the Tools pull down menu of the VM600 CMS Software the CMC 16 captures 42,799 point waveforms with a user definable bandwidth on all pre-selected vibration channels. The waveforms configurable fixed frequency bandwidths range from 25 Hz to 20 khz. The waveform duration is inversely proportional to the bandwidth. If 25 Hz is selected, then the sampling period will be approximately 11 minutes. If 20 khz is selected, the period is 0.84 seconds. Waveforms are acquired in parallel. VM600 Overview Page 12 of 27

13 VM600 CMS SOFTWARE VM600 CMS Software is developed for use as a Condition, Performance and Vibration Monitoring System for turbo machinery. VM600 CMS Software acquires data from VM600 racks containing MPC4, AMC8, CMC 16 and CPU-M modules. The data acquired from VM600 racks, third party systems (i.e. DCS, PLC, and PCS), can be integrated into the monitoring database and are used to assess the condition of the plant under surveillance and predict impending damage. Applications Condition Monitoring of Turbo machinery in Power Utilities, Oil, Gas and Petrochemical Industries Vibration and Performance Monitoring of Steam Turbines, Gas Turbines, Gearboxes, Generators, Compressors, Pumps Main Features Combines Condition and Vibration Monitoring Features Displays include trend and polar plots, spectra and waveforms, waterfall diagrams, transients, orbits, shaft centerline, real-time mimic diagrams, list of recent events, machine run hours and more Spectra, orbit, run-up, rundown signatures compared with baseline Runs under the Windows XP, 2000 and 2003 server platform Remote Database Access is possible over modem or Ethernet communication network from other PCs User-friendly and easy to operate over Ethernet network Adaptive Monitoring User-configurable cause and effect message generation (automatic diagnosis) External Data Interfaces to third-party systems Techniques for Condition Monitoring Many techniques have been developed to monitor machine condition, but still the single most important pointer to the mechanical integrity of the machine is the vibration behavior. Degradation in the mechanical condition of the machine can be associated with a change in vibration characteristics. In line with this requirement, VM600 CMS Software includes the most widely used vibration techniques, presented in a manner which can be easily interpreted. However, since Condition Monitoring goes beyond vibration monitoring, various other techniques have been included. VM600 is a Total Condition Monitoring System designed to cover the present and future requirements for condition monitoring of Rotating Machines. It incorporates packages for Vibration Monitoring, Performance monitoring, Combustion Monitoring and allows off-line data to be monitored within the database - for example from portable data collectors or plant management systems.
