Working Principle: Each channel of the 3300/36 operates independently, receiving voltage signals from its respective 3300 XL proximitor. The module conditions both signals simultaneously, providing buffering, filtering, and scaling. The DC component of each channel represents static displacement, while the AC component represents dynamic vibration. Both conditioned signals are output to the monitoring system for independent processing, alarm comparison, and protective action. The dual-channel architecture enables redundant monitoring configurations where two probes measure the same physical parameter for voting logic.
Installation Requirements:
- Install in a compatible 3300/3500 series equipment rack
- Connect two independent proximitor output cables using shielded wiring
- Each channel requires its own dedicated power supply connection
- Ensure proper cable length matching for each transducer system
- Route signal cables separately to minimize crosstalk between channels
Usage Notes:
- Verify both channels are properly configured in the monitoring system software
- Check individual channel LED indicators for independent status verification
- Each channel can be independently bypassed for maintenance without affecting the other
- Ensure proper shield grounding for each channel to prevent ground loops
- Confirm proximitor system lengths match total cable lengths for each channel independently
