  6. CONTROL PROGRAM IN EVENT OF FAULT

  7. INDICATION OF OPERATION

  8. SELF-DIAGNOSTIC Operating concept · Burner control has initiated lockout Þ Red 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 Þ «Error code table A»

  9. 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
