‌Mandatory Validation Tests‌

test_sequenceCopy Code

1. TMR Integrity Test:

   • Inject step signal (10%→90% FS)

   • Verify voting consistency (%AIx_DIAG = 0)  
2. Burnout Simulation:

   • Open circuit on Ch4 → Confirm %ALMxx = 1

3. SIL Verification: • PFDavg = 2.7E-9 (Mission time 10yr) • SFF = 99.2%

Test Procedure:

  1. Apply 25V AC between field wire and earth

  2. Verify alarm: GFx bit in %S0003

  3. Trip threshold: >5mA leakage

‌Diagnostics & Indicators‌

‌LED‌	‌State‌	‌Fault Condition‌
‌OK‌	Red	Channel disagreement
‌ACTIVE‌	Green flashing	Firmware update in progress
‌COMM‌	Amber solid	TMR comm sync failure

‌Troubleshooting Matrix‌

Fault Code: E105

  Cause     : Channel deviation >0.5% for 5s

  Action    : 1. Verify sensor calibration

              2. Check HART multiplexer

              3. Replace faulty sub-module
