2 The standard for online machine surveillance The vbonline machinery health information system provides automated, user-scheduled monitoring of the health of your critical assets. It is a flexible, modular system that automatically evaluates machinery condition using permanently installed sensors and the award-winning Ascent analysis software. Ongoing monitoring by the vbonline system assists in the early detection of mechanical problems, helping you avoid costly downtime. The vbonline system performs frequent data collection more cost effectively and with improved accuracy compared to traditional walkaround portable monitoring programs, and with the added benefit of greater safety for monitoring machines in dangerous or inaccessible environments. Within reach

3 vbonline connectivity Each vbonline device connects directly to the LAN / WAN network within your plant. Controlled and managed on a single user PC or across a network, our system is simple but flexible and easily expandable. As your surveillance needs increase, simply plug in additional modules and sensors or activate more channels. Ascent software Displays spectra, waveforms, and overalls Schedules data collection intervals Automatically checks alarms Controls status LEDs automatically Notifies of alarm conditions Client PC Client PC Local TCP/IP-based Ethernet network or wireless LAN/WAN vbonline module 4 to 32 analog channels 1 to 4 tachometer inputs 12/24 V DC input Spring cage connectors 1 to 4 switch relays Red, yellow, and green LED status indicators Sensors vbonline module Vibration data Process values Tachometers Local alert system

4 vbonline - A complete surveillance system The vbonline machinery health monitoring system is built on a foundation of data acquisition modules capable of measuring between 4 and 32 channels each, providing flexible tailor-made solutions to suit your plant environment. LED indicators display the current status of the vbonline module at a glance. Additionally, each module is equipped with up to 4 relay outputs. These are configurable according to alarm condition, giving you the fastest response time to problems on the factory floor. Relays can be configured to activate audible alarms, warning lights, and even machine shutdowns if particular alarm states are triggered. Speed reference is accepted by up to 4 tachometer inputs. Pulse-type speed input gives you the option to configure the number of tach pulses per revolution. Each vbonline module uses an Ethernet connection to transfer data to the host computer. You can connect directly to your plant s wired network or, for that difficult to monitor machine, simply integrate the vbonline device into a wireless (Wi-Fi) network.

5 Key vbonline features Modular design for system expansion Compact and easy to install 4 to 32 channel options, expandable in the field Powerful Ascent Level 3 vibration analysis software Common software platform that supports vbonline and vbseries portable systems Simultaneous dual-channel data sampling Single user PC or network compatible Wired or wireless Ethernet connection 24-bit analog-to-digital conversation Able to accept machine data from the following sensor types: - Accelerometers - Velocity probes - Proximity probes - AC/DC signal ma Automatic alarm detection and reporting Plant personnel alerted by or text/sms message Event-triggered data collection Award-winning software management The vbonline machinery health information system is managed by the award-winning Ascent software suite. The powerful Ascent, OnlineManager, AscentOPC, and AscentWatcher software tools provide users with advanced charting, trending, and analysis capabilities; together with scheduling, data integration, and monitoring in a userfriendly and easy-to-use package. Ascent provides the flexibility and power needed to trend vibration and process data over time, display sophisticated charts, create advanced automated reports, trigger alarms, and track machinery performance. OnlineManager enables scheduled measurements to be taken by your vbonline system, obtaining an accurate snapshot picture of machinery condition and regular data for advanced trending. AscentOPC distributes existing measurement data to client applications across your network using the OPC standard. AscentWatcher monitors measurements as they are taken, alerting you to potential problems via onscreen alerts, s, or text messages.

7 vbonline integration with Bently Nevada 3500 system at hydroelectric facility in Peru The permanent vbonline condition monitoring system successfully integrates with the Bently Nevada 3500 system. A hydroelectric plant providing energy to several South American countries wanted to add vibration analysis of their hydro generators to their protection system. Installing a permanent online system would ensure scheduled readings were regularly monitored and analyzed, with the data transmitted offsite. Two 32-channel vbonline systems were set up to take 39 readings from buffered outputs of a Bently Nevada 3500 rack. These signals corresponded to 18 radial proximity probes, 6 axial probes, 3 Keyphasor, and 12 airgap sensors. All sensors were pre-installed in three hydro generators of 44.5 MW each. Reliable seismic readings were critical. Eighteen low frequency sensors with dual output (measuring vibration and temperature) were installed in a radial direction and aligned with the probes. The first vbonline system was configured to take measurements from the seismic sensors, ensuring the vibration from the shaft was taken, along with vibration measurements from the journal bearing structure. The second vbonline system was configured to take measurements from 12 critical oil pumps and 2 air compressors, connecting to 32 general-purpose accelerometers distributed over the oil pumps and compressors. These readings were taken twice a day. Once operational, analysts were able to view data trends and full spectrum data rather than simple overalls.
