The Bently Nevada 3500/93 135785-01, also cataloged as the 3500/93 135785-01 System Display Module, operates as a dedicated hardware component for local visualization and annunciation of rack-level machine protection and condition monitoring data within 3500 Series machinery protection system platforms.

Model Identification Data

The 3500/93 135785-01 serves as a localized human-machine interface (HMI) for the 3500 rack. The part number 135785-01 identifies the specific hardware iteration designed for panel-mount integration, providing status updates on input modules and alarm events processed by the rack's internal backplane bus.

Hardware Specifications

Rotor Dynamics and TSI Integration

The 3500/93 display module interfaces directly with the 3500 rack backplane to pull data derived from eddy-current probe inputs. While the module does not perform primary signal conditioning, it provides the visualization necessary to validate gap voltage targets, typically checked at -10 VDC for standard probes. The module supports real-time monitoring of rotor dynamics, including vibration amplitudes and shaft centerline positions, ensuring that operators can verify rotor response metrics without direct connection to the host configuration software. Effective cross-talk suppression in the associated input modules is visually confirmed via the display's alarm and OK status indicators.

Field Installation Guidelines

• Panel Cutout: Ensure the cabinet panel cutout adheres to the dimensions specified in the installation drawing to maintain seal integrity.

• Mounting: Secure the module using the included hardware to ensure a vibration-resistant connection to the control panel.

• Backplane Seating: Fully insert the module into the designated slot in the 3500 rack until the lever-actuated connector engages with the backplane.

• Cabling: Use appropriate strain relief for any external interface cables connected to the rear of the module to prevent backplane stress.

• Grounding: Verify that the 3500 rack chassis is properly bonded to the control system common ground to prevent noise interference with display data.

Frequently Asked Questions

• Q: Can this module be hot-swapped while the 3500 rack is powered?

  A: Yes, the 3500/93 is designed for removal and insertion under power, provided the rack backplane is secured.

• Q: Does this module require internal configuration via software?

  A: Yes, the display must be configured using the 3500 Rack Configuration Software to define which rack slots and data points are mapped to the display.

• Q: What is the purpose of the alarm LEDs on the display?

  A: The LEDs mirror the alarm status of the individual monitoring modules within the rack for immediate visual annunciation of fault conditions.

• Q: Is this display compatible with all 3500 rack versions?

  A: Compatibility depends on the rack's firmware and backplane revision; verify support in the system configuration software.

• Q: Does the module support touch input?

  A: The 3500/93 is primarily a display and annunciation unit and does not typically support touch-based control inputs.

• Q: Can I connect multiple 3500/93 modules to one rack?

  A: Yes, the system architecture supports the installation of multiple display modules to provide information at different physical locations.

• Q: How are communication errors reported on the display?

  A: Loss of communication with the rack backplane is indicated by a specific "Comm" or "OK" LED fault status on the display face.

• Q: Does the display retain data during power failure?

  A: The module does not store historical trend data locally; it displays real-time data provided by the rack’s monitoring modules.
