Bently Nevada Machinery Condition Monitoring 3500 System

Description

The 3500 System provides continuous, online monitoring suitable for

machinery protection applications, and is designed to meet the

requirements of the American Petroleum Institute’s API 670 standard

for such systems. The system’s modular rack-based design includes

the following components:

l 3500/05 Instrument Rack (required)

l One or two 3500/15 Power Supplies (required)

l 3500/22M Transient Data Interface (TDI) Module (required)

l One or more 3500/XX Monitor Modules (required)

l One or more 3500/32M (4-channel) or 3500/33 (16-channel)

Relay Modules (optional)

l One or two 3500/25 Keyphasor* Modules (optional)

l One or more 3500/92 Communication Gateway Modules

(optional)

l Input/Output (I/O) Modules (required)

l 3500/94M VGA Display (optional)

l Internal or external intrinsic safety barriers, or galvanic isolators

for hazardous area installations (optional)

l 3500 System Configuration Software (required)

System components are described in more detail in the following

section and in their individual datasheets.

System Components

This section describes the individual components that make up a complete 3500 system.

Instrument Rack

The standard 3500 Rack is available in 19” EIA rail-mount, panel-cutout-mount, and bulkhead-mount versions.

The rack provides slots for two Power Supplies and a TDI in the left-most rack positions that are reserved exclusively for these modules. The remaining 14 slots in the rack can accommodate any combination of monitor, display, relay, Keyphasor module, and communication gateway modules.

All modules plug into the rack’s backplane and consist of a main module and an associated I/O module. The I/O module installs at the rear of the rack for panel-mount systems, and above the main module for bulkhead-mount systems.

Standard rack depth is 349 mm (13.75 inches), while bulkhead mount rack depth is 267 mm (10.5 inches). NEMA 4 and 4X weatherproof housings are available when required for environmental protection or when purge air is used.

Mini Rack

A mini rack (12” wide instead of 19”) is also available and features 7 available monitor slots instead of 14. Like its larger counterpart, the left-most slots are reserved for the Power Supply or Supplies and TDI Module.

The mini rack may be mounted in a panel cutout or, using an optional adapter plate, on 19” EIA mounting rails. Bulkhead mounting is not available.
