Operating concept

Burner control has initiated lockoutRed fault LED on

Reset Press lockout reset button for about 1 s

Diagnosis of cause of fault – Press lockout reset button for > 3 s– Press again lockout reset button for > 3 s– Read blink code of red fault LED

«Error code table A»

SELF-DIAGNOSTIC

BUrners TRAining CEntre

Error code table A

Blink code Possible cause

2 x No establishment of flame at the end of «TSA»– Faulty or soiled detector electrode

– Faulty or soiled fuel valves– Poor adjustment of burner

– Faulty ignition equipment

3 x Faulty air pressure monitor – «LP» faulty

– «LP» incorrectly adjusted – Fan motor does not run

4 x extraneous light on burner startup

7 x Loss of flame during operation– Poor adjustment of burner

– Faulty or soiled fuel valves – Short-circuit between detector electrode and ground

10 x Wiring error or internal fault, output contact, unidentifiable fault, e.g. faults that occurred simultaneously
