Installation Instructions

1. Preparation
   Ensure the probe mounting location is clean and free from debris or oil contamination. The shaft surface should be smooth and target runout must be within acceptable range.

2. Probe Mounting
   Insert the 330703 probe into the pre-threaded mounting hole (3/8-24 UNF) and tighten using a torque wrench to 20–24 in-lbs. Make sure the probe face is within 2 mm of the shaft surface.

3. Cable Connection
   Connect the probe to the extension cable, ensuring the connector lock is secure. Route the cable through protective conduit if used in high-vibration zones.

4. Proximitor Sensor Setup
   Connect the extension cable to the Proximitor sensor. Calibrate the system using a dial gauge and Bently Nevada software to confirm displacement output accuracy.

5. System Integration
   Connect the Proximitor to the 3500 Monitoring System. Verify signal strength and linearity using the system diagnostics tool.

6. Final Inspection
   Recheck all mechanical fasteners and electrical connections. Record baseline data before placing the system into live monitoring mode.
