Core Functions

1. Keyphasor pulse signal transmission: Deliver clean phase‑reference trigger pulse from proximitor output to 3500/25 monitor module, for shaft speed, phase angle, orbit and order‑analysis calculation.
2. EMI noise suppression: Multi‑layer shielding reduces industrial‑site electromagnetic interference, avoids pulse distortion and missing trigger events.
3. System signal matching: Fixed electrical‑length assembly maintains impedance matching for correct Keyphasor signal waveform.

Installation, Replacement & Critical Warnings

1. Non‑hot‑swap field‑wiring component; de‑energize relevant channel during replacement.
2. Compatibility warning: ‑ Pre‑fabricated 3‑meter assembly; do not cut, splice or re‑terminate on‑site. ‑ Mainly used with 3500/25 Keyphasor‑speed monitor module and compatible proximitor. ‑ Inspect connector pins for bending, corrosion and contamination during installation.
3. After replacement: Verify speed reading, key‑phasor trigger status in rack configuration software; confirm orbit‑diagram function is normal.

4. Common failure mode: Internal conductor breakage, connector pin damage, shielding degradation; symptoms: intermittent / lost speed signal, missing key‑phasor event, orbit‑plot unavailable. Cable fault itself will not initiate machinery‑protection trip.
