ABB Uvisor™ FAU 810 – Flame Analysis Unit

ABB Uvisor™ FAU 810 – Flame Analysis Unit

DESCRIPTION

The Flame Analysis Unit, or FAU810, is ABB’s latest  leading-edge fl ame analysis device. The FAU810 is designed from the ground up for maximum  fl exibility, usability and reliability. It 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.

Collects Signal Values from the Flame Detector

The FAU810 analyzes the signals generated from the Flame  Detector.

Calculates Signal Quality

The FAU810 measures the quality of the signal to provide an  indication of changes in the burner flame. Quality values act as a barometer, forecasting when a burner  flame-out is likely to occur. This can help you to anticipate  changes and problems.

Continuously Detect Faults

The instrument automatically monitors the electronic  components of the Flame Detector and FAU810 unit to detect  system problems or faults.

Signals Unsafe Conditions

A no-flame condition occurs when the FAU810 logic  determines that an unsafe condition exists.

Remote supervisory

Extended set-up, parameter fi les archiving, groups view,  advanced diagnostic including fl ame raw data, real time and  historical trends of up to 254 scanner heads networked is  possible either through the PC based package Flame ExplorerTM or with DTM through any Profi bus DP-V1 master remote.

FAU810 Specifications

Each Flame Analysis Unit consists of two independent  channels. Each channel can receive and process a Flame  Detector signal. The two Detectors may be in any combination  of the following designs: 

− SF810 Flame scanner heads 

− All DFS Flame scanner heads 

− Flame Rods (Ionic Flame Monitoring)

Each Detector is independently configurable from the FAU810  pushbuttons and display, with Flame Explorer engineering tool  or via Profibus The FAU810 can be powered by a single or redundant 24  VDC source (+/- 20%). The FAU810 has built-in diode auctioneering for power source  isolation. Two digital input channels are available for remote parameter  switching. One digital input per sensor. (Example: Parameters for a dedicated Flame Detector may be  tailored to monitor either coal or oil firing) The FAU810 can be upgraded on site with any official  release of new product features by the proprietary Firmware  Download Utility.
