Bently Nevada 3500/93 (135785-02) — System Display Screen Monitor | 3500 Series Condition Monitoring Platform
Engineering Background
The Bently Nevada 3500 Series is the industry-standard platform for continuous machinery protection and condition monitoring in rotating equipment applications. Deployed globally across power generation, oil & gas, petrochemical, and heavy industrial facilities, the 3500 rack architecture provides modular, scalable monitoring for turbines, compressors, pumps, and motors. The 3500/93 System Display Screen Monitor serves as the primary human-machine interface (HMI) for the 3500 rack, enabling real-time visualization of channel data, alarm states, and system health without requiring a separate PC or software connection.
Product Positioning
The 3500/93 (P/N 135785-02) is a rack-mounted display module designed for procurement engineers and reliability teams who require a direct, panel-level readout of all monitored parameters. It eliminates dependency on external workstations during commissioning, routine inspection, and fault diagnosis — a critical advantage in field environments where network access is restricted or unavailable.

Proven Application Environments
- Power Generation: Gas turbine and steam turbine protection racks requiring local display during startup and shutdown sequences
- Oil & Gas: Offshore and onshore compressor trains where remote HMI access is restricted by safety zone classifications
- Petrochemical & Refining: Continuous process monitoring where operators require panel-level alarm acknowledgment without DCS dependency
- Heavy Industry: Large motor-driven equipment where maintenance teams perform periodic walk-around inspections using rack-mounted displays
- Commissioning & FAT: Factory acceptance testing environments requiring standalone rack readout prior to DCS integration
Engineering Advantages
- Standalone Visualization: Displays all 3500 rack channel values, alarm setpoints, and system status directly on the module — no laptop or Rack Configuration Software required for routine readout
- Rapid Fault Identification: Color-coded alarm indication and channel navigation allow technicians to isolate faults at the rack level within seconds
- Backplane Integration: Communicates natively over the 3500 internal bus — zero additional wiring, zero configuration overhead
- Hot-Swap Compatible: Designed for insertion and removal in live racks per Bently Nevada field service procedures (verify with site safety protocol)
- Reduced MTTR: Local display capability reduces mean time to repair by enabling immediate on-site diagnosis without remote access infrastructure
System Architecture & Signal Flow
The 3500/93 occupies a dedicated display slot within the 3500 rack chassis. It interfaces with the rack’s internal communication bus to poll all installed monitor modules (vibration, temperature, speed, position, etc.) and renders their current values, alarm states, and channel identifiers on the integrated screen. Navigation is performed via front-panel controls. The module does not process or condition any field signals — it is a pure display and status interface layer within the 3500 architecture.

Technical FAQ
Q: Is the 3500/93 compatible with all 3500 rack configurations?
A: Yes. The 3500/93 is designed to operate with any standard 3500 rack chassis and is compatible with all 3500 Series monitor modules. Confirm slot assignment with your rack layout drawing.
Q: Does this unit include firmware or require programming?
A: The 3500/93 does not require independent firmware programming. It reads configuration and channel data from the rack’s existing system configuration automatically upon insertion.
Q: Can the 3500/93 replace a failed display on an existing live rack?
A: Yes, subject to site hot-swap procedures. The module is designed for field replacement. Consult Bently Nevada Service Manual GEK-91485 for detailed replacement procedures.
Q: What is the difference between 135785-01 and 135785-02?
A: The -02 revision incorporates minor hardware updates per Bently Nevada’s engineering change order process. Functionally equivalent for standard display applications — confirm with your OEM documentation if revision-specific compliance is required.
Q: Do you provide export documentation for customs clearance?
A: Yes. Full commercial invoice, HS code declaration, and packing list are provided. ECCN classification and end-user statements available upon request for controlled-destination shipments.
