DESCRIPTION
The Fireye Phoenix type 85UVF/IRF flame scanners are microprocessor based devices utilizing a solid
state flame detection sensor. The Phoenix flame scanners incorporate an internal flame relay with auto-
matically set ON/OFF thresholds, thereby eliminating the need for a remote flame amplifier or flame
switch.
Phoenix scanners detect the amplitude of the modulations (the flame “flicker”) that occur within the tar-
geted flame, over a wide frequency. During the scanner setup procedure, the amplitudes of the target
flame are automatically stored by the flame scanner, together with optimum ON/OFF criteria. The appro-
priate sensor gain is automatically selected. Phoenix scanners incorporate full self diagnostics and elec-
tronic self checking.
The Phoenix 85UVF/IRF is available in multiple models differentiated by spectral range, levels of hazard-
ous area certifications and agency approvals. Refer to Table 1 on page 3 for an overview of model num-
bers versus product certifications.
The Phoenix 85UVF/IRF flame scanner is powered by 24Vdc. Electrical connection is via an 8-pin elec-
trical quick-disconnect (QD). An analog 4 to 20mA output of flame strength is standard.
Note: The Phoenix QD models with electrical quick-disconnect have replaced the original models
equipped with ten feet of captive cable. The QD models (with 59-546-x cables) are suitable for use in
Class I Division 2 hazardous areas, thereby eliminating the need for "EX" models. The "CEX" mod-
els remain unchanged for use in Ex II 2 G/D hazardous areas.
APPLICATION
Fireye Phoenix 85UVF self-checking scanners are used to detect 295 to 340 nanometers wavelength ultra-
violet emissions. The Fireye Phoenix 85UVF1-1QDK3 and 85UVF1-1CEX-K3 Flame Scanners are
derivatives of the standard Phoenix product but utilizing an advanced optical filter. This filter adjusts the
optical sensitivity of the detection cell to pick up wavelengths of light from the standard 310 nm range up
to 500 nm.
Typical Applications:
Duct Burners, Industrial Gas Burners, Refinery Applications, Low NO
x
Burners,
Waste Gas Units and Incinerators. The K3 scanner is particularly suited to measure the light emissions
from steel plant applications such as burners firing blast furnace gas and coke oven gas.
Fireye Phoenix 85IRF self checking scanners are used to detect 830 to 1100 nanometers wavelength infra-
red emissions. They are suited for application to duct burners, industrial gas burners, refinery applications
ignition systems and Low NOx detection and for continuous or non-continuous burner operation.
Typical Applications:
Duct Burners, Industrial Oil Burners, Refinery Applications, Waste Oil Units and
Incinerators.
NOTE:
Because the sensors in the Phoenix are solid state devices they can perform well
with many different fuels. For example UV is typically used on gaseous fuels but can also be applied to
oils and heavy oils. To be 100% sure of correct application a test should be performed.
We DO NOT recommend the Phoenix scanner for use on small pilot flames or obstructed sighting.
OPERATOR & SYSTEM INTERFACE
Operator interface to the Phoenix scanner is via a pushbutton keypad and informative LEDs. These pro-
vide continuous indication of flame signal, flame relay status, scanner status as well as selected mode of
operation. Simplified keystroke routines are used for setup and this can be completed in seconds. For
remote interface, outputs are provided for flame switch, fault relay and 4 to 20mA flame strength.
