Decision Tree: Oven / Temperature

← Back to Alarms Hub ABB GC Codes → Chromatogram Guide
Goal: Stabilize oven temperature at setpoint before judging sulfur results.
1) Check setpoint versus actual temperature and note alarms.
2) If temperature is low: check heater power path, fuses, and relays.
3) If temperature hunts: check sensor integrity, wiring, and airflow.
4) Confirm cabinet ventilation and ambient conditions are acceptable.
5) Run 2–3 cycles and verify stable retention time.
