BENTLY NEVADA 350094M-03-00-00 (3500/94M) – Local rack display for 3500 machinery protection systems

The BENTLY NEVADA 350094M-03-00-00 is a 3500/94M System Display variant designed to present real-time status, measured values, and alarms directly from a 3500 rack. From my experience, plants use it when they want quick, on-panel visibility without spinning up a separate HMI or historian view. You might notice that it’s especially handy during startup, commissioning, or quick fault investigations, where a clear VGA display and front-panel navigation can save precious minutes.

Order Placement Process and Guarantees

Key Features

• Native 3500 rack visualization – Displays channel values, alarms, and system status pulled directly from the rack.
• VGA display support – Connects to a standard VGA monitor for clear, panel-mounted viewing in control cabinets.
• Front-panel navigation – Simple menu access to alarm lists and status pages; typically minimal training required.
• Backplane data interface – Reads data via the 3500 system backplane, so no extra signal wiring is needed.
• Hot-swap capable – In most cases, supports controlled replacement per 3500 rack procedures to minimize downtime.
• Event and alarm insight – Helps technicians confirm trip conditions and returning-to-normal states quickly.

Technical Specifications

Application Fields

This module is commonly used across turbomachinery protection applications where immediate, cabinet-mounted visibility is preferred:

• Gas/steam turbines, centrifugal compressors, and large pumps in oil & gas and petrochemical plants
• Power generation (combined-cycle, thermal plants) for on-skid or MCC room visibility
• Pipeline compressor stations and refineries where operators need quick alarm confirmation
• OEM skid packages that require a compact, integrated display tied to the 3500 rack

A maintenance lead at a combined-cycle site told me the 94M screen “cut our trip investigation time by half—values and alarms were right there when we opened the cabinet door.”

Advantages & Value

• Reliability – Uses the proven 3500 backplane data path; fewer external points of failure.
• Compatibility – Designed for the 3500 rack, including systems with 3500/22M TDI and standard monitor modules.
• Cost & time savings – Avoids the need for a separate HMI for local checks; typically shortens troubleshooting time.
• Supportability – Straightforward to commission and service; accessible menus and clear VGA output.

Installation & Maintenance

• Cabinet environment – Mount the 3500/05 rack in a clean, ventilated enclosure; keep ambient temperature within the 3500 system rating.
• VGA display wiring – Use a quality shielded VGA cable; route away from high-noise power conductors; avoid sharp bends and excessive length.
• Grounding & ESD – Follow plant ESD precautions; maintain proper cabinet grounding for noise immunity.
• Hot-swap practice – Follow the 3500 rack procedure. In many cases, modules are hot-swappable, but verify with the site’s MOC and OEM guidance.
• Routine checks – Periodically inspect connectors, clean dust from vents and the cabinet, and review firmware revision alignment with the rack (when applicable).
• Documentation – Keep the 3500/94M manual accessible for menu maps and configuration notes; it seems to save time during audits.

Quality & Certifications

• Manufacturer quality systems typically aligned with ISO 9001
• Common compliance: CE marking; UL/CSA recognition; RoHS where applicable
• Warranty: 365 days (repair/replace policy as supplied)
