Bently Nevada 3500/05-01-02-00-00-01 System Monitor – Core Control for the 3500 Condition Monitoring Rack

The Bently Nevada 3500/05 System Monitor (often written as 3500-05-01-02-00-00-01) is the supervisory module that keeps your 3500 machinery protection rack coordinated and healthy. From my experience, this card quietly oversees rack status, alarm processing functions like Trip Multiply and Bypass, and general “OK” health—so the rest of your vibration, temperature, and relay modules stay focused on acquiring and protecting. You might notice that it doesn’t add sensors or network ports; it stabilizes the backbone logic so the system behaves predictably in demanding plants.

Company’s Order Placement Process and Guarantees

• Warranty: 365 days
• Delivery time: typically 1 week if in stock, no more than one month at the latest
• Payment terms: 50% advance payment; full payment before delivery
• Express options: FedEx, UPS, DHL

Key Features

• Rack Health Supervision – Continuously monitors overall 3500 rack status and “OK” integrity so faults are surfaced quickly.
• Alarm Logic Coordination – Implements system-level functions such as Trip Multiply and Bypass for managed shutdown behavior during startup or maintenance.
• Front-Panel Status Indication – Clear LED indicators simplify at-a-glance checks during rounds; useful when the network is not your first stop.
• Hot-Swappable Design – Typically replaceable without taking down the entire rack, reducing outage time.
• Seamless with 3500 Architecture – Works with 3500/22M TDI, 3500/15 power supplies, and the full range of 3500 monitoring and relay modules.

Technical Specifications

Application Fields

In many cases this module finds its place anywhere a 3500 rack protects rotating assets:

• Steam and gas turbines in power generation (start-up Trip Multiply is particularly handy)
• Compressors in oil & gas midstream and refining units
• Large pumps, fans, blowers in chemical plants and water facilities
• Paper machines and critical balance-of-plant machinery in heavy industry

Advantages & Value

• Reliability – A mature, field-proven system card that stabilizes rack behavior; fewer nuisance trips when set up correctly.
• Compatibility – Designed to work with the broader 3500 ecosystem (proximitor, seismic, temperature, and relay modules) without extra engineering.
• Reduced Downtime – Hot-swap capability typically means swap/restore in minutes during a planned window.
• Lifecycle Support – Long product availability and strong parts ecosystem help maintenance teams standardize spares.

A maintenance supervisor at a gas compression station told us they swapped a 3500/05 during a short outage; the rack came back healthy immediately, and they kept Trip Multiply active for a controlled startup. That kind of practical confidence seems to be why many plants stick with the 3500 platform.

Installation & Maintenance

• Environment – Install the 3500 rack in a clean, ventilated cabinet (19-inch), with adequate clearance for airflow. Maintain ambient conditions within the module’s temperature rating.
• Wiring & Grounding – Ensure proper rack grounding; follow Bently Nevada wiring practices for alarm and relay circuits. Avoid mixed ground references.
• Hot Swap – The 3500/05 is typically hot-swappable; still, coordinate with operations, set Bypass/Trip Multiply appropriately, and observe ESD precautions.
• Routine Checks – Periodically verify front-panel LEDs, exercise Bypass/Trip Multiply during scheduled tests, and confirm alarm logic via your 3500/22M connection.
• Firmware & Records – Keep firmware harmonized across the rack where applicable, document configuration baselines, and back up settings after any change.

Quality & Certifications

• CE compliant
• UL/cUL for industrial control equipment (typical for 3500 modules)
• RoHS adherence
• Manufacturer’s warranty supported; our warranty coverage: 365 days

Related and Supporting Modules (for a complete 3500 system)

• 3500/22M TDI – Rack data interface for configuration and Ethernet connection to condition monitoring software.
• 3500/15 Power Supply – AC or DC power supply options for the rack backplane.
• 3500/32M Relay Module – Alarm and danger relays for shutdown and annunciation.
• 3500/42M Proximitor/Seismic Monitor – Vibration inputs for shafts, bearings, and casing measurement.
• 3500/60 – Temperature monitoring for essential thermal points.

Note: The 3500/05 does not replace sensor or relay functionality; it coordinates and supervises them. For networking and data acquisition, pair it with a 3500/22M TDI and the appropriate monitoring cards for your assets.
