6.5.2 Normal operation / flame detection time
The control box has a function through which it is possible to as-
certain the correct functioning of the burner (signal: GREEN LED
permanently on).
To use this function, it is necessary to wait at least 10s. from the
time the burner switches on and press the button on the control
box for at least 3 seconds.
Once the button is released, the GREEN LED starts to flash, as
shown in Tab. H.
The pulses of the LED constitute a signal spaced by approxi-
mately 3 seconds.
The number of pulses will measure the probe detection time
since the opening of gas valves, according to: Tab. I.
This is updated in every burner start-up.
Once read, the burner repeats the start-up cycle by briefly press-
ing the control box button.
