The Bently Nevada 163179-01, also cataloged as the 3500/60 Temperature Monitor, operates as a dedicated hardware component for multi-channel thermal data acquisition within the 3500 machinery protection system network.

Model Identification and Configuration

The 163179-01 represents a specific hardware configuration of the 3500/60 Temperature Monitor module. This unit is designed to interface directly with RTD (Resistance Temperature Detector) or thermocouple inputs to provide continuous thermal status monitoring for industrial rotating machinery, facilitating integration into the 3500 rack backplane for alarm and shutdown logic processing.

Physical and Electrical Specifications

TSI and Signal Conditioning Characteristics

The 3500/60 module utilizes precise signal conditioning to mitigate common-mode noise inherent in industrial environments. For temperature sensing, the module provides excitation currents necessary for RTD measurements while maintaining galvanic isolation between the sensor input and the 3500 rack power supply. The module performs local data validation against programmable alarm setpoints and communicates detected high/alert conditions to the 3500 Rack Interface Module (RIM) via the internal rack backplane. Accuracy is maintained through continuous self-diagnostic routines that monitor for sensor open-circuits, short-circuits, and internal A/D converter drifts.

Ordering and Packaging Information

• 163179-01 Temperature Monitor Module (Standard version)

• I/O Module (Requires corresponding terminal block for sensor wiring)

• Documentation set (Standard Bently Nevada 3500 system configuration manual)

• Installation mounting hardware (Standard rack-mount assembly components)

Mechanical and Field Installation

• Ensure the module is installed in a slot compatible with the 3500 series backplane interface.

• Verify that the I/O module is firmly seated before applying power to the rack.

• Shielded twisted-pair cabling is required for all sensor inputs to ensure signal integrity against electromagnetic interference (EMI).

• Ensure proper chassis ground connection to the rack mounting rail to minimize ground loops.

• Do not exceed the maximum terminal wire gauge specifications for the associated terminal blocks.

Technical FAQ

• Q: Does the 163179-01 support hot-swapping?

  A: Yes, the 3500/60 module is designed for hot-swapping in a powered 3500 rack without interrupting the operation of other modules in the system.

• Q: What sensor types are supported by this monitor?

  A: It supports common RTD inputs (e.g., 100 ohm Platinum) and standard thermocouple types; refer to the specific configuration software for supported ranges.

• Q: How does the module indicate a sensor failure?

  A: The module executes a fault relay output and flags a "Not OK" status in the rack communication data when an open or short circuit is detected on the input.

• Q: Is the IP20 rating sufficient for outdoor use?

  A: No, the IP20 rating signifies indoor use only; it requires an external NEMA or IP-rated enclosure for protection against moisture and environmental contaminants.

• Q: What is the primary communication method?

  A: The module communicates internal alarm and process data to the 3500 Rack Interface Module (RIM) via the high-speed proprietary rack backplane bus.

• Q: Can this module be configured via front panel buttons?

  A: Configuration is primarily performed via the 3500 Rack Configuration Software connected to the RIM, not via physical switches on the module faceplate.

• Q: Does it require external cold junction compensation?

  A: No, the module provides internal cold junction compensation for thermocouple inputs to ensure measurement accuracy across the operating temperature range.

• Q: How is the alarm logic managed?

  A: Alarm logic is programmed via the configuration software and processed locally on the module, which then signals the relay modules in the rack to execute.
