Installation & Maintenance Instructions:

• Installation:
  • Mount the 330750-40 Velomitor on a stable surface of the machine, ensuring that the sensor is positioned as close to the vibration source as possible to provide accurate readings.
  • Select the appropriate mounting style (threaded or stud) depending on your machine configuration.
  • Connect the 4-20 mA output signal to a compatible vibration monitoring system or controller.
  • Ensure proper wiring connections to avoid grounding issues or electrical noise that could interfere with the sensor’s readings.
  • When installing in high-temperature environments, ensure that the sensor is placed in a location that does not exceed the maximum temperature rating.
• Maintenance:
  • The Velomitor system is designed for minimal maintenance. However, periodic checks should be performed to ensure that the wiring, connectors, and mounting hardware are secure.
  • Clean the sensor regularly to remove dust, dirt, or other debris that may affect sensor performance. Use a non-abrasive cloth to wipe the housing and connectors.
  • Inspect the vibration monitoring system for any irregularities in readings. If the system detects excessive vibration or other issues, check the machine components (e.g., bearings, couplings) for signs of wear or damage.
• Troubleshooting:
  • If vibration readings are inconsistent or fail to provide reliable data, verify the wiring connections and ensure there is no interference from nearby electrical equipment.
  • If the sensor is operating in extreme temperature conditions, ensure it is not being exposed to temperatures beyond its rated operating range.
  • For any error codes or system malfunctions, refer to the Bently Nevada diagnostic tools or consult the user manual for troubleshooting guidance.
