Siemens MAXUM Edition II – Alarm Codes
Common alarm categories, symptoms, and recommended first actions (technician quick reference).
Typical MAXUM II Alarm Categories
- Carrier Pressure / Flow – supply low, regulator hunting, leaks, restriction
- Oven Not Ready / Temperature Deviation – heater, sensor, airflow/venting
- Valve / Sequence / Injection – solenoid/air issues, sticking valves, timing mismatch
- Detector / Electronics – noise, instability, signal out of range (check grounding & contamination first)
- Communication / I/O – network, Modbus/OPC settings, mapping/scaling, quality status
Field Best Practice
- Resolve carrier & sampling issues before touching method/electronics.
- After corrective action, verify with 2–3 stable runs.
- Many “GC faults” are utility (air/power) or sampling problems.
