Forney UniFlame User Manual
UNIFLAME - UNITIZED FLAME DETECTOR WITH AMPLIFIER
Forney's Uniflame series flame detectors utilize micro-processor based technology in
combination with solid state infrared (IR), ultraviolet (UV), or dual (IR and UV) sensors.
Three models are properly suited for gaseous, liquid, solid, or combination fuel firing.
The infrared model uses an infrared sensor sensitive to radiation prevailing in both
#2 and #6 oil or coal fired applications. The Ultraviolet Model employs an
ultraviolet sensor detecting radiation prevalent in gas or #2 oil fired applications.
The MultiSpectral Model incorporates both the ultraviolet and infrared sensors
to detect the radiation from any variety of the three fuels. The configuration of
each detector allows for application on wall fired or tilting-tangentially fired
burners.
An adjustable flame relay resides in the body of the Uniflame detector,
eliminating the need for a remote amplifier. The Uniflame series flame
detectors work on an amplitude and frequency (flame flicker) principle
providing the best tuning control where high discrimination is required. The
appropriate flicker frequency and amplitude gain is automatically configured in
the AutoTune mode and can be manually adjusted via the Edit mode.
• AUTOMATIC AND MANUAL ADJUST-
MENT of the flame relay “on” and “off”
thresholds.
• OPTICALLY ISOLATED 4-20MA flame
signal output for remote signal indi-
cation.
• SPST FLAME RELAY for BMS safety
interlock and independent SPST
alarm relay.
• FOUR SELECTABLE PROGRAM FILES
capable of storing separate setpoints
based on fuel, load or process condi-
tions.
• REMOTE RS485 COMMUNICATIONS
via Windows 95/98/NT user soft-
ware for tuning and flame analysis.
• ELECTRONIC SELF CHECK - no
mechanical shutter which reduces
maintenance costs.
• FULLY SELF DIAGNOSTIC and dis-
played via eight character alphanu-
meric LED display.
• SAFE 24 VDC OPERATION to ensure
safe working environment for the
plant.
