Configured for shaft and rotor displacement measurement in 3500 monitoring systems, the Bently Nevada 3500/45 176449-04 (3500/45 Position Monitor) provides direct electrical execution of transducer signal processing and alarming functions.

Model Identification

• Model: 3500/45

• Part Number: 176449-04

• Product Type: Position Monitor Module

• System Family: 3500 System

Hardware Specifications

Mechanical Monitoring & TSI Integration

The 3500/45 module performs real-time rotor dynamics analysis by processing inputs from proximity transducers. Eddy-current probe scaling is configurable within the module software to match the specific transducer type installed on the machinery. During commissioning, installers must perform gap voltage validation, targeting -10 VDC as the reference midpoint for linear range operation. The module utilizes internal logic for cross-talk suppression when multiple probes are monitored in proximity, ensuring that measured displacement values are not influenced by adjacent high-frequency signals.

Ordering Information

• One (1) 3500/45 Position Monitor Module.

• I/O module matching for transducer termination.

• Configuration and installation documentation.

Field Installation Guidelines

• Insertion: Slide the module into the designated 3500 rack slot; ensure the backplane connector is fully engaged and the locking levers are secured.

• Wiring: Connect transducer field wiring to the corresponding I/O module using shielded cabling to maintain noise immunity.

• Grounding: Verify the rack and cabinet grounding scheme adheres to 3500 system requirements to prevent ground loops in the TSI signal path.

• Configuration: Utilize 3500 Rack Configuration software to map inputs and define alarm setpoints before placing the machine into service.

Frequently Asked Questions

• Is the 3500/45 module hot-swappable? Yes, the 3500 system supports hot-swapping of monitor modules without interrupting the operation of other modules in the rack.

• Does this module support dual-channel configuration? Yes, the monitor accepts inputs from multiple proximity transducers to provide redundant or comparative position measurements.

• What is the purpose of the 176449-04 suffix? This part number denotes the specific hardware revision and feature set compliant with the 3500 system standards as of its manufacturing date.

• How are alarm setpoints defined? Alarms are configured via the 3500 software interface, allowing for proportional danger and alert limits based on physical displacement.

• Can the module be used with older 3500 racks? Yes, the 3500/45 is designed for backward compatibility with 3500 system racks and common I/O modules.

• What diagnostic data is available? The module provides real-time status bits including "Module OK," "Configuration Error," and transducer channel health status to the 3500 Rack Interface Module (RIM).

• Does it provide pass-through signals? The I/O module typically provides buffered output signals for each channel, accessible via front-panel or rear-connector test pins for external analysis.

• Is the IP67 rating applicable to the module itself? The IP67 rating applies to the module when installed within a compliant housing or enclosure environment specified for 3500 series systems.
