Move the scanner while observing the LEDs on the back of the scanner. One-half of the LEDs will turn red
and light up just 1 bar when no flame is detected; when running under the auto gain mode, LEDs on the
other half will show purple color, and the LED bar will increase from a minimum of 1 to a maximum of 8.
When the flame relay is energized, the LEDs will show green color, and the LED bar will increase from a
minimum of 2 to a maximum of 8, as shown in Figure 10.
DO NOT use the scanner if the LEDs are all yellow and/or flashing yellow.
NE PAS utiliser le scanner si les voyants sont tous jaunes et clignotants.
