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– 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 ignition safety time– Faulty or soiled flame detector

– Faulty or soiled fuel valves– Poor adjustment of burner

– Faulty ingnion equipment

4 x Extraneous light during pre-purging– Or internal device fault

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

– Faulty or soiled fuel valves – Faulty or soiled flame detector

8 x Time-out release contact for oil pre-heater does not close

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