CONTROL PROGRAM IN EVENT OF FAULT
Cause Reponse
Mains failure Restart with program sequence
Voltage dropped belowundervoltage threshold
Restart with program sequence
Premature flame signal Lock-out
Burner does not ignitewithin safety time
Lock-out
Loss of flame duringoperation
3 repetitions, then lock out
Oil temperature doesnot reach set valuewithin 600 sec fromactivation of # 8
Lock-out

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
