Bently Nevada 3500 Monitoring System Rack General Information

Monitoring and computerized vibration information systems provide the information

you need to assess the mechanical condition of rotating and reciprocating machinery.

These systems continuously measure and monitor various supervisory parameters

and provide crucial information for early identification of machinery problems such as imbalance,

misalignment, shaft crack, and bearing failures.

As such, these systems are an efficient and effective means of satisfying plant management,

engineering, and maintenance concerns for:

• Increasing plant safety by minimizing the occurrence of hazardous conditions or catastrophic failures.

• Improving product quality by minimizing process variances caused by improperly operating equipment.

• Maximizing plant availability by servicing only those machines that require it and providing more efficient turnarounds.

• Reducing plant operating costs by minimizing unplanned shutdowns and by making more efficient use of maintenance resources.

For protection of critical machinery, we highly recommend that you permanently install continuous monitoring systems.

The term "protection" means that the system can shut down machinery on alarm, without human interaction.

These systems include applicable transducers, each with its own dedicated monitoring circuitry and alarm setpoints.

The 3500 Monitoring System is the newest addition to the family of continuous monitoring systems offered by Bently Nevada, LLC.

3500 Monitoring System

The 3500 is a full-feature monitoring system whose design incorporates the latest in proven processor technology.

In addition to meeting the above stated criteria, the 3500 adds benefit in the following areas:

• Enhanced operator information

• Improved integration to plant control computer

• Reduced installation and maintenance cost

• Improved reliability

• Intrinsic Safety (IS) option

The following sections discuss these benefits in more detail.

Enhanced Operation Information

The 3500 design includes features to both enhance the operator's information

and present this information so that the operator may easily interpret it.

These features include:

• Improved data set

- Overall amplitude

- Probe gap voltage

- 1X amplitude and phase

- 2X amplitude and phase

- Not 1X amplitude

• Windows®-based Operator Display Software

• Data displayed at multiple locations

Improved Integration to Plant Control Computer

The 3500 improves integration to the plant control computer with:

• Communication Gateways supporting multiple protocols

• Time synchronized vibration and process information

Reduced Installation and Maintenance Costs

The 3500 system provides the following cost-saving features:

• Reduced cabling costs

• Downward product compatibility

• Improved space utilization

• Easier configuration

• Reduced spare parts

• Improved serviceability

Improved Reliability

The 3500 offers several features to improve system reliability.

• Redundant power supplies available

• Triple Modular Redundant (TMR) monitors and relay cards available

Intrinsic Safety Option

If you wish to monitor equipment that is located in hazardous atmospheres,

the 3500 Monitoring System has a range of I/O modules with internal zener barriers.

These modules provide an Intrinsically Safe interface between the 3500

rack and the transducers located in the hazardous area.

Multiple Output Interfaces

You can conveniently adjust monitor options (such as full scale ranges, transducer inputs,

recorder outputs, alarm time delays, alarm voting logic, and relay configuration) in the field via software.

Modular system design employs plug-in components which allow easy servicing and expansion.

The following three independent interfaces are available with the 3500 system:

• Data Manager Interface (Transient Data Interface External or Dynamic Data Interface External)

• Configuration/Data port

• Communications Gateway (support for Programmable Logic Controllers,

Process Control Computers, Distributed Control Systems, and PC-based Control Systems)

These interfaces allow you to easily view monitored parameters and their statuses in the following ways:

• System 1® Software

• Bently Nevada™ 3500 Operator Display Software

• Remote display panel

• DCS or PLC display

Convenient front panel coaxial connectors provide dynamic transducer signals

and allow you to connect diagnostic or predictive maintenance instruments.
