Software diagnostics

Reports burner life by means of an optical link with the PC, indicating hours of operation, number and type of lock-outs, serial number
of control box etc.
To view diagnostics, proceed as follows:
– Hold the button down for more than 3 seconds once the red LED (burner lock-out) remains steadily lit.
A yellow light pulses to tell you the operation is done.
Release the button for 1 second and then press again for over 3 seconds until the yellow light pulses again.
Once the button is released, the red LED will flash intermittently with a higher frequency: only now can the optical link be activated.
Once the operations are done, the control box's initial state must be restored using the resetting procedure described above.
Button pressed for
Between 1 and 3 seconds
More than 3 seconds
More than 3 seconds starting from the visual
diagnostics condition
The sequence of pulses issued by the control box identifies the possible types of malfunction, which are listed in the table on pag. 23
SIGNAL
No blink The burner does not start 1
2 led blinks After pre-purge and the
safety time, the burner
goes to lock-out and the
flame does not appear
4 led blinks The burner starts and
then goes into lock-out
Control box
Control box reset without viewing visual diagnostics.
Visual diagnostics of lock-out condition: (LED pulses at 1-second intervals).
Software diagnostics by means of optical interface and PC (hours of operation,
malfunctions etc. can be viewed)
