5. CONTROL PROGRAM IN EVENT OF FAULT

6. INDICATION OF OPERATION

7. 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»

8. 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 ···· · Eextraneous light on burner startup
7 x ······· · Loss of flame during operation
– Short-circuit between detector electrode and ground
10 x ·········· · Wiring error or internal fault, output contact, unidentifiable fault, e.g. faults that occurred simultaneously
