5. Installation & Wiring

Rack Mounting

  1. Insert module into Quantum rack slot; push until latched.

  2. Hot‑swap supported (rack power ON).

Field Wiring (24 VDC Sensors)

  • +24 V → Sensor supply

  • Sensor − → Module INx−

  • Sensor + → Module INx+

  • Common → 0 VDC (field ground)

  • Shield → Earth ground (single point)

  • Cable: Twisted pair, screened; max 500 m

  • Separate from high‑voltage / high‑power cables

6. Configuration (Unity Pro)

  1. Unity Pro V7.0+; add 140SDI95300S to hardware list.

  2. Set input filter: 1 / 5 / 10 ms.

  3. Enable diagnostics: open/short, overvoltage, mismatch.

  4. Map 4 input words to safety process data.

  5. Configure 1oo2 / 2oo2 voting for SIL3.

  6. Download configuration; module runs autonomously.

7. Safety & Diagnostics

  • SIL3 operation: Continuous self‑tests, cross‑channel comparison, signal plausibility checks.

  • Fault response: On fault, FAULT LED ON, safety logic sets channels to safe state (user configurable).

  • Diagnostic coverage: >95% for safe faults (SIL3).

  • Safety data: Dual‑channel voting, fault flags in process data.

8. Operation & Maintenance

Normal Operation

  • PWR: ON

  • RUN: ON

  • FAULT: OFF

  • CH LEDs: ON/OFF per input state

Troubleshooting

  • FAULT ON: Check wiring (open/short), field power, sensor failure, or module fault.

  • CHx Flash: Channel x open/short or overvoltage.

  • No update: Verify backplane power, module seating, or configuration.

Maintenance

  • Inspect wiring quarterly; clean terminals.

  • Verify safety diagnostics semi‑annually.

  • Update firmware via Unity Pro (Schneider Electric website).

9. Safety Notice

  • Qualified personnel only for installation/service.

  • SIL3 applications require safety plan, periodic proof tests, and fault response procedures.

  • Do not open module; no user‑serviceable parts.

10. Compatibility

  • Quantum CPU: 140CPU65150/67160/68060 and above

  • Software: Unity Pro V7.0+, Safety Library (SIL3)
