Flame Analysis Unit | FAU 810 | ABB

Technical Specifications

The FAU810 takes advantage of the latest technologies available to make fl ame analysis as cost-effi cient as possible, while retaining ABB’s rock-solid reputation as the most reliable instruments in the industry. The FAU810 is easy to install and confi gure, fl exible to operate, and uses redundant Profi bus DP-V1 or standard Modbus interfaces for easy and safe data exchange and tuning. You can connect any type of ABB Flame sensing device to the FAU810. This makes the FAU810 the standard module for all ABB Flame Scanner application and the preferred solution for retrofi tting existing installation. It determines if the current signal value is within the programmed limits as defi ned by Functions. A variety of limits can be defi ned in the FAU810 to account for any situation that may occur in utility or industrial boilers.

Troubleshooting & Comissioning Checklist

Power Quality Check: Confirm the 24 VDC power supply stays within the tolerated +/- 20% window.
Mounting Alignment: Verify the Line of Sight (LOS) scanner is directly aligned with the target burner flame zone.\
Lens Cleaning Air Flow: Ensure clean ambient air provides 115 l/min for LOS versions or 400 l/min for Fiber Optic (FOC) setups.

Field Engineering Considerations

Sensing Configurations: Each channel can process signals from the ABB Uvisor SF810 series, legacy DFS scanners, or standard ionic flame rods.
Sensor Selection: Deploy UV sensors for gas flames, IR sensors for coal/oil, or dual UVIR/IRIR scanner heads (such as the SF810-PYRO) to optimize discrimination in multi-fuel burners.
Power Supply Redundancy: Provide dual 24 VDC sources (± 20%). The FAU810 includes built-in diode auctioneering to automatically isolate power faults without interrupting operation.

Technical FAQ

Q: What software is used for configuration and remote monitoring?
A:The unit can be managed locally via its physical pushbuttons and display. For plant-wide network architectures, it integrates with ABB Flame Explorer™ software. 

Q: Can it handle different fuel types automatically?
A: Yes, via remote parameter switching. The unit features two dedicated digital input channels (one per sensor). This allows operators to automatically switch between customized configuration profiles on the fly—for example, instantly adjusting thresholds when a burner transitions from burning coal to oil.

Q: How does the unit calculate and use "Signal Quality"?
A:Beyond standard flame/no-flame logic, the FAU810 actively measures the underlying quality of the flame signal. This value behaves like a barometer, giving operators a predictive forecast of burner flame stability and helping to anticipate a flame-out before an emergency trip occurs.

Q: Do you supply brand-new, original parts or second-hand refurbished items?

A: Our stock consists of Original New items; all products undergo quality inspection to ensure they are fully functional.

Q: What guarantees are included with the shipment?
A: All items in stock are tested by engineers, packed in professional ESD packaging, and shipped via express logistics with a global delivery time of 24–48 hours.

Q: How long does global shipping take?
A: Stock items are typically dispatched within 24 hours. Shipments are sent via DHL or FedEx Express, taking approximately 3–5 days to reach Asia, 4–6 days to Europe and the Middle East, and usually arriving within a week in major industrial regions worldwide.

Q: If the model I need is not listed on the website, can I request a quote?
A: Yes. We hold over 200,000 SKUs of industrial spare parts in stock, and many long-tail models are not listed in full. You can send us an RFQ (Request for Quote) directly, and we will provide wholesale pricing promptly.
