Technical description of the burner
Operation sequence of the burner
Legend to the sequence diagrams:
Valve proving takes place depending on the parameter:
1)
Parameter: short / long preignition time
short / long oil pump switch - switch-on time -
time
3) Parameter: with/without alarm in the event of start prevention
5) 28 s = maximum time safety phase, followed by lockout
6) 5 s = time between occurrence of start prevention and
signaling
0° Position as supplied (0°)
90° Actuator fully open (90°)
