Eddy-Current Probe Scaling and Gap Voltage Validation
The 3500/25 supports scaling of eddy-current proximity probe outputs to match target mechanical clearances. Gap voltage validation is executed against a -10 VDC nominal target, ensuring transducer alignment prior to turbine roll. Cross-talk suppression logic prevents false triggering between adjacent keyphasor channels in high-density rack installations.
Frequently Asked Questions
Q: Does the 3500/25 support hot-swap replacement without system shutdown?
A: Hot-swap is supported only if redundant keyphasor channels are configured; otherwise, phase data for affected monitors will be temporarily unavailable.
Q: What is the maximum backplane current load per module?
A: The module draws approximately 0.5 A at 24 VDC from the rack backplane supply.
Q: Can the 3500/25 operate with magnetic pickups instead of proximity probes?
A: Yes. Both magnetic pickup and proximity probe inputs are accepted with appropriate signal conditioning enabled in configuration software.
Field Installation Guidelines
Mount the module in any available half-height slot within the 3500 rack. Ensure shield termination of transducer cables at the I/O module grounding lugs to maintain noise immunity. Maintain separation of at least 15 cm between keyphasor signal wiring and high-voltage AC conductors. Verify gap voltage before initial startup using System 1 configuration tools.
