Safety function
A safety shutdown occurs:
- if a flame signal is present during
preventilation (parasitic flame
monitoring).
- if no flame is produced within 5 seconds
(safety time) of start-up (fuel
authorisation).
- if no flame is produced after an
unsuccessful restart attempt in the
event of flame failure during operation.
A safety shutdown is indicated by the
malfunction lamp lighting up and it is then
only possible to reenable the burner by
pressing the reset button after the cause
of the malfunction has been rectified.
For further information, see the
automatic combustion control unit
