5. Installation & Wiring

Rack Mounting

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

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

Field Wiring (8‑channel, 3‑wire sensors)

• +24 V → Sensor power

• Sensor − → Module INx−

• Sensor + → Module INx+

• Shield → Earth ground (single point)

• Cable: Twisted pair, screened; max 500 m

• No parallel routing with high‑voltage cables

6. Configuration (Unity Pro)

1. Unity Pro V7.0+; add 140SAI94000S to hardware list.

2. Set input range: 0–25 mA (fixed).

3. Enable diagnostics: open/short, out‑of‑range.

4. Map 13 input words to process data.

5. Download configuration; module runs autonomously.

7. Safety & Diagnostics

• SIL2 operation: Module performs continuous self‑tests, cross‑channel comparison, and signal plausibility checks.

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

• Diagnostic coverage: >90% for safe faults (SIL2).

8. Operation & Maintenance

Normal Operation

• PWR: ON

• RUN: ON

• FAULT: OFF

• CH LEDs: ON (active channels)

Troubleshooting

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

• CHx Flash: Channel x open/short or out‑of‑range.

• 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.

• SIL2 applications require safety plan and periodic proof tests.

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

10. Compatibility

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

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