ABB Symphony Plus Flame Scanner UvisorTM SF810i

Unrivalled overall capability and performance

The Symphony Plus Flame Scanner takes full advantage of the system architecture, unrivalled scalability and simplicity, CPU performance and communication speed. It is this

combined with the Uvisor™ SF810i Flame Scanner makes for an ideal flame failure protection system.

The Uvisor™ SF810i is a multi-fuel scanner that provides consistent and reliable information on flame presence and quality for utility and industrial boiler burners.

The Uvisor™ SF810i utilises state-of-the-art technology in a ruggedised housing:

- Solid-state sensor module covering the entire flame radiation spectrum (UV-VL-IR and dual-sensor UVIR)

- Signal processor unit: extremely powerful module capable of running ABB's proprietary flame analysis process.

The real-time measurement of dynamic flame parameters is continuously subjected to extensive fail-safe verification procedures before the flame status is voted on.

- Communication drives: Redundant PROFIBUS DP-V1 links (or redundant standard Modbus) provide high-speed data transfer to external

Monitoring system

- Terminal and configuration board with local display and buttons for initial setup and online aiming assistance.

The integrated scanner is supplied with screw-type removable terminals as standard and can be supplied with IP66/67 or ATEX II 2GD EX d IIC T6 quick connectors for non-hazardous and hazardous areas respectively, for ease of maintenance.

The Uvisor™ SF810i Flame Scanner is available with accessories for the following installations:

- Line of sight (LOS) for wall burners

- Fibre optic cable (FOC) with outer conduit, cooling hose and connector flange for angle burner tilt burners

- Extended setup, parameter file archiving, group viewing, advanced diagnostics including raw flame data, real-time and historical trends for up to 254 scanning heads

Networkable via PC-based software packages

PROFIBUS communication interface

UvisorTM SF810i modules are fully integrated via the built-in convenient PROFIBUS DP interface. The main features of the interface are as follows

- DP/V1 communication standard

- Communication rates up to 12 MBd

- Compliance with PROFIBUS PNO slave specification

- System (master) redundancy

- Flight (line) redundancy

- 2 independent PROFIBUS slave hardware interfaces per module

- DTM and GSD files available

PROFIBUS interface for exchanging parameters, commands, and process variables with the Symphony Plus controller, eliminating the need for locally adjusted jumpers or switches.
