ABB Uvisor™ FAU810 – Flame Analysis Unit
Flexible and Reliable Device for use with all ABB FlameDetectors.
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.
