Faults - Possible causes - Solutions

6
If faults arise in ignition or operations, the burner performs a "safety stop", which is signalled by the red burner lockout LED. The display
visualises alternately the lockout code and the relative diagnostic.
To reset the start-up conditions, refer to "Reset procedure". When the burner starts up again, the red LED goes out.

Recommended measures
Leak test
Check if the valve on the side of the burner has any leaks.
Check if the pressure switch for the leak test (PGVP) is closed when gas pressure is not
present.
CPI
Check the wiring.
Check if the CPI contact is closed.
Leak test
Check if the valve on the side of the gas has any
leaks.
CPI
Check the wiring.
Check if the CPI contact opens when the valve is powered.
Carry out a reset; if the error arises repeatedly, replace the control box

Carry out a reset; if the error arises repeatedly, replace the control box
No valid load
Adjust the curve points of all the actuators
Set the standby position of all the servomotors used
Set the post-purging position of all the servomotors used
Set the pre-purging position of all the servomotors used
Set the ignition position of all the servomotors used
Carry out a reset; if the error arises repeatedly, replace the control box
No valid load
Adjust the curve points of all the servomotors
Carry out a reset; if the error arises repeatedly, replace the control box
The slope of the curve can correspond to a maximum position variation of 31°
between 2 points of the modulation curve
