1. Purpose and Functions

This module is positioned as a dedicated temperature monitoring and I/O interface component within the 3500 series control system. It is mainly responsible for core functions such as temperature signal acquisition, measurement, processing, and data transmission. As a key component for on-site temperature parameter monitoring, it enables real-time temperature supervision of equipment and process operations, delivering reliable data for equipment fault early warning and process optimization. Its specific functions are as follows:

• Multi-channel temperature monitoring: Equipped with 6 independent temperature monitoring channels, it supports both RTD (Resistance Temperature Detector) and TC (Thermocouple) measurement types. It can simultaneously monitor temperature changes at multiple critical equipment or process points, meeting the demand for synchronous multi-point monitoring in industrial sites and adapting to temperature monitoring scenarios for various rotating and fixed equipment.
• 
  
• High-precision temperature measurement and processing: Adopting high-precision sensors and advanced signal processing technology, it achieves measurement accuracy up to ±0.1% FS and a resolution of 0.1°C (0.18°F), with a measurement range covering -200°C to +600°C (-328°F to +1112°F). It accurately captures subtle temperature variations, while filtering and amplifying collected temperature signals to ensure accurate and stable data transmission.
• 
  
• Data acquisition and transmission: Supporting multiple industrial communication protocols, it can form a complete TSI (Turbine Supervisory Instrumentation) system with Bently Nevada 3500 racks, power supplies, and communication modules, enabling real-time acquisition and transmission of temperature data for operators to monitor equipment temperature status in real time. It also supports data uploading to control systems such as SCADA and DCS for centralized monitoring and management.
• 
  
• Flexible configuration and commissioning: Parameters can be configured via dedicated Bently Nevada 3500 software with user-friendly operation. Measurement types, alarm thresholds, and other parameters can be flexibly set according to monitoring requirements in different industrial scenarios without complex hardware modifications, adapting to diverse temperature monitoring needs.
• 
  
• Fault warning and status feedback: Featuring temperature anomaly warning, it issues timely alarm signals when monitored temperatures exceed preset thresholds to alert operators of potential faults. It also provides real-time feedback on its own operating status, facilitating troubleshooting of the module and associated equipment and reducing fault resolution time.

3. Troubleshooting Guidelines

• Fault symptom identification: Abnormal temperature data, acquisition failures, temperature alarms, or abnormal communication of the module in the control system may indicate module failure. Overheating or loose wiring at the module installation location also requires priority inspection of the module status and connections.
• 
  
• Basic inspection steps: First check for loose or oxidized wiring and ensure intact, undamaged terminal connections. Next, use professional tools to measure the input power voltage (24V DC) to identify power abnormalities. Inspect the module installation environment to verify compliance with temperature, humidity, and dust requirements to avoid environment-induced failures.
• Application of diagnostic tools: Use dedicated Bently Nevada 3500 configuration software to read module operating data and fault codes, locating root causes such as channel faults, incorrect parameter settings, or communication anomalies. Calibrate measurement accuracy via software to check for measurement deviations.
• 
  
• Precautions for replacement and maintenance: Before replacement, inspect other components such as 3500 series racks and communication modules for faults to prevent recurrence after installation. Replacement must be performed with power disconnected, and electrostatic protection must be applied to avoid damaging internal electronic components. After replacement, reconfigure parameters and calibrate accuracy using dedicated software to ensure system compatibility and proper temperature monitoring performance. For routine maintenance, regularly clean dust from the module surface and inspect wiring tightness to extend service life.
