BENTLY 3500/50M

Product introduction

The Bently Nevada 3500/50M is a dedicated operator interface module, designed to provide real-time visibility into the status of 3500 series machinery protection systems. As the primary local access point for operators, it consolidates data from sensors, transmitters, and monitoring modules—such as the 85515-02 vibration transmitter and 3500/33-01-00 vibration monitor—into a user-friendly display, enabling quick decision-making in industrial environments.

Unlike remote software interfaces like 170180-01-00, the 3500/50M offers on-site access to critical information, making it indispensable for facilities where immediate physical presence is required. It communicates seamlessly with the 3500/05-01-02-00-00-00 rack interface module, ensuring that data from even EMI-prone or remote locations (transmitted via optical fiber) is displayed in real time.

Powered by reliable supplies such as the 106M1079-01 or 3500/15 127610-01, the 3500/50M is built to withstand harsh industrial conditions, from steel mills to remote power plants. Its rugged design and intuitive interface make it a critical component for operators needing to monitor, acknowledge, and respond to machinery alarms without relying on external computers.

Core advantages and technical highlights

Localized real-time monitoring: The 3500/50M provides instant access to critical parameters—such as vibration levels from the 85515-02 or alarm statuses from the 3500/33-01-00—directly at the equipment rack. This eliminates the need for operators to access remote software, reducing response times during emergencies. The 1-second data refresh rate ensures that the latest readings are always displayed, a crucial feature for time-sensitive situations like turbine overspeed events.

Intuitive alarm management: The module prioritizes alarms by severity (warning, danger) and displays them with clear visual indicators, allowing operators to quickly identify critical issues. It supports alarm acknowledgment, reset, and silencing via the 16-key keypad, with tactile feedback ensuring operation even while wearing gloves. This functionality streamlines workflow in high-stress environments, where clarity and speed are essential.

Seamless integration with 3500 ecosystem: The 3500/50M communicates with the 3500/05-01-02-00-00-00 rack interface module via the backplane, enabling it to display data from across the entire system—including sensors in EMI-heavy areas connected via optical fiber. It automatically recognizes connected modules (like the 3500/42M 140734-02) and configures display screens accordingly, reducing setup time and ensuring compatibility.

Rugged design for harsh environments: With an operating temperature range of -40°C to +70°C and resistance to humidity and vibration, the 3500/50M performs reliably in extreme conditions. Its backlit LCD remains readable in both bright sunlight and dark control rooms, while the sealed keypad prevents damage from dust or accidental spills—critical for longevity in industrial settings.

Typical application scenarios

In a steel mill’s rolling mill control room, the 3500/50M is mounted alongside the 3500 series rack, displaying vibration data from 85515-02 transmitters on mill rolls. When a dangerous vibration threshold is exceeded, the module flashes a red alarm and sounds a local buzzer, prompting operators to acknowledge the alert via the keypad. The display shows real-time trends, allowing quick comparison to historical values and facilitating immediate action—such as reducing mill speed—without accessing remote software.

At a remote hydroelectric plant, the 3500/50M provides on-site visibility into turbine health, receiving data via the 3500/05-01-02-00-00-00’s optical fiber link. Operators use the module to monitor bearing temperatures and vibration levels during turbine startups, verifying normal operation before leaving the site. The backlit display ensures readability in the dimly lit turbine hall, while the rugged design withstands temperature fluctuations.

In a chemical plant’s hazardous area, the 3500/50M is part of a redundant monitoring setup, paired with the 3500/05-01-02-00-00-00 and 3500/15 127610-01 power supply. It displays pump vibration data from 85515-02 transmitters, with alarms configured to trigger shutdowns via the 3500/62 module. Operators use the keypad to acknowledge alarms and view diagnostic details, ensuring compliance with safety protocols without exposing mobile devices to explosive atmospheres.

Installation, commissioning and maintenance instructions

Installation preparation: Mount the 3500/50M in 2 consecutive slots of the 3500 series rack, securing it with screws torqued to 0.6 Nm. Ensure the rack is powered off (via 106M1079-01 or 3500/15 127610-01) during installation. Connect the RS-232 port to external devices (e.g., printers) if needed, using shielded cable. Verify that the module is aligned with the backplane connector to ensure communication with the 3500/05-01-02-00-00-00 and other components.

Commissioning steps: Power on the system and confirm the 3500/50M’s power LED illuminates. Use 170180-01-00 software to configure display screens, selecting which parameters (e.g., 85515-02 vibration, 3500/33-01-00 alarms) to show. Test alarm propagation by simulating a fault (e.g., exceeding vibration thresholds) and verifying the module displays the alert with correct severity. Calibrate the backlight and contrast for the installation environment, ensuring readability under all lighting conditions.

Maintenance suggestions: Inspect the 3500/50M monthly for keypad responsiveness and display clarity. Clean the screen with a soft, dry cloth to remove dust or smudges. Check cable connections to external devices quarterly, ensuring secure RS-232 links. Test alarm buzzer functionality semi-annually by triggering a test alarm. If the display dims or keys fail, replace the module during a scheduled shutdown—hot-swapping is not recommended to avoid data loss.
