BURNER START-UP CYCLE DIAGNOSTICS

During start-up, indication is according to the following table: 

OPERATING FAULT DIAGNOSTICS

The control box has a self-diagnostic system, which easily allows identifying the operating faults (

RED LED

 signal).

ITo use this function, wait at least ten seconds from the safety lock out, and then press the reset button for a minimum of 3 seconds.
After releasing the button, the RED LED starts flashing as shown in the diagram below.

The pulses of the LED constitute a signal spaced by approximately 3 seconds.
The number of pulses will provide the information on the possible faults, according to the table below:

SIGNAL

PROBABLE CAUSE

2 flashes 

The flame does not stabilise at the end of the safety time:

– faulty ionisation probe;

– faulty or soiled gas valves;

– neutral/phase exchange;

– faulty ignition transformer

– poor burner regulation (insufficient gas).

3 flashes 

Min. air pressure switch does not close:

– air pressure switch faulty;

– air pressure switch incorrectly regulated;

– max. air pressure switch triggered (if installed).

4 flashes 

Min. air pressure switch does not open or light in the chamber before firing:

– air pressure switch faulty;

– air pressure switch incorrectly regulated.

7 flashes 

Loss of flame during operations:

– poor burner regulation (insufficient gas);

– faulty or soiled gas valves;

– short circuit between ionisation probe and earth.

8 flashes 

–  Not used.

10 flashes 

– Wiring error or internal fault.
