Diagnostic Relay

  • Normal: Energized (contacts closed)

  • Fault: De‑energized (contacts open) – triggers on power loss, module failure, or optical fault


5. Installation

5.1 Rack Mounting

  1. Ensure Quantum rack power is OFF (or hot‑swap in powered rack).

  2. Align module with rack slots, insert firmly until seated.

  3. Secure with rack latch.

5.2 Cable Connections

Fiber Ports (LC Duplex, Single‑Mode)

  • Tx → Rx of remote module; Rx → Tx of remote module.

  • Cable: 9/125 µm single‑mode fiber.

  • Min bend radius: 10× cable diameter.

Coaxial Port (BNC)

  • Cable: 75 Ω (RG‑6 or equivalent).

  • Max length: 100 m (copper segment).

5.3 Harsh Environment Notes

  • Conformal coating protects against condensation, dust, and mild corrosives; do not immerse or expose to direct liquid spray.


6. Configuration

  • No manual configuration: Auto‑detects RIO S908 network.

  • Software: Unity Pro V7.0+; add to I/O list, download project.

  • Topologies: Point‑to‑point, dual redundant, multidrop (up to 31 drops).


7. Operation & Maintenance

Normal Operation

  • READY: Green ON

  • COM ACT: Green flashing

  • OPT FAULT: Red OFF

  • ERR: Red OFF

Troubleshooting

  1. OPT FAULT ON:

    • Check Tx/Rx reversal, dirty/damaged LC connectors, tight bends, or wrong fiber type (must be single‑mode 9/125 µm).

  2. ERR ON:

    • Re‑seat module, check 5 V backplane power, replace module if fault persists.

  3. READY OFF:

    • Verify rack power, check backplane short circuits.

Maintenance

  • Quarterly: Inspect and clean LC connectors (isopropyl alcohol).

  • Semi‑annually: Test diagnostic relay.

  • Firmware: Update via Unity Pro (check Schneider Electric website).


8. Safety

  • Qualified personnel only for installation/service.

  • Disconnect power before rack maintenance.

  • Laser safety: Class 1 LED (1300 nm) – no eye hazard under normal use.


9. Ordering & Compatibility

  • 140NRP95401C: Coated single‑mode, LC duplex connectors.

  • 140NRP95400C: Coated multimode, ST connectors.

  • 140NRP95400: Non‑coated multimode, ST connectors.
