Once the start-up signal (
) has been applied, the au-
tomatic burner control unit checks the burner for flame
simulation during the waiting time t
W
. If no flame simu-
lation is detected during that period, the safety time
on start-up t
SA
(3, 5 or 10 s) then starts to elapse. This
forms the minimum operating time of the automatic
burner control unit and the burner. Voltage is supplied
to the gas valve and ignition transformer. After the safe-
ty time on start-up t
SA
has elapsed and the flame signal
has been received, the operation signalling contact be-
tween terminals 13 and 14 closes. The display indicates
the current program status
04
.
If, after a successful burner start, the automatic burner
control unit does not detect a flame signal during the
safety time on start-up t
SA
, a fault lock-out will occur
(fault signalling contact between terminals 8 and 9
closes). During the entire safety time on start-up t
SA
,
the gas valve V1 is open. The display blinks and indi-
cates
