3.0 Technical Specifications
3.1 Definitions
FLICKER – Flicker or Flicker Frequency refers to the modulation of flame intensity due to micro-explosions.
FDORT – Flame Detector ON Response Time – the period of time from flame intensity rising above the
user-adjustable threshold to flame relay contacts closed.
FDRT – Flame Detector Response Time –the period of time between the loss of a sensed flame and the
signal indicating the absence of flame.
MFFRT – Marginal Flame Fail Response Time – period of time from flame intensity falling below the user
adjustable threshold to the flame relay contacts open.
ROL – Ring of Light – multi-colored LED status indication on the back of the scanner.
iScan Software – Flame scanner communications software is used to monitor and configure the iScan®3
Flame Scanner.
GAIN – When a signal is amplified, GAIN is the ratio of the amplified signal relative to the original.
DISCRIMINATION – The ability to distinguish between multiple flames. An example of good discrimination
is when the MB scanner is able to recognize a pilot flame with another burner’s main fuel flame in the
background. The status of the background Flames does not affect the ability to detect the pilot flame (ON
or OFF).
