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
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
