FAU810 Flame Analysis Units ABB Burner Management Systems

The ABB FAU810, also cataloged as the FAU810 Flame Analysis Unit, operates as a dedicated hardware component for physical flame signal processing and discrimination tasks within industrial burner management architectures. It converts the analog current frequencies delivered by optical flame sensors into specific evaluation metrics to monitor flame presence and stability.

Hardware Specifications

Profinet / EtherNet/IP Deterministic Networks and I/O Density Scaling

The internal signal processing architecture utilizes high-speed filtering to isolate flicker frequencies specific to combustion zones. In control systems demanding optimized multi-burner I/O density scaling profiles, the module routes real-time flame spectrum matrices back to the process controller interface. This dynamic parameter distribution connects seamlessly with upper-tier industrial topologies running Profinet / EtherNet/IP deterministic networks, ensuring that safety-critical trip signals and flame intensity curves are transmitted without packet latency or processing jitter.

Frequently Asked Questions

Q: Can the FAU810 module be hot-swapped while the burner rack is actively running?

A: No. Live replacement of the core processing module is prohibited. The sensor input lines and auxiliary supply terminals must be completely isolated and de-energized prior to structural detachment to prevent hardware damage from signal transient spikes.

Q: How is an optical sensor line breakdown detected by the internal electronics?

A: The module executes a continuous background diagnostic routine that checks sensor loop impedance and current parameters. If a short-circuit or wire break occurs, the device updates its internal error register and switches the flame status relay to a de-energized fault state.

Field Installation Guidelines

• Electrostatic Grounding Measures: Technical operators must attach an approved ESD grounding wrist strap to a verified bare-metal enclosure grounding terminal before handling internal terminal blocks or card link switches.
• Mechanical Alignment and Torque: Secure the unit firmly within its designated sub-rack or mounting panel. Tighten all faceplate retention fasteners to 1.2 Nm to ensure structural integrity against industrial vibration profiles.
• Sensor Shielding Separation Rules: Route the low-level analog input cabling from optical flame sensors through dedicated grounded conduits, maintaining a minimum clearance of 150 mm from high-voltage igniter ignition cables and power supply conductors.
