6.4 Safety check function
The safety check function may only be performed by authorized staff.
It is possible to activate
· the floss-of-flame test, and
· the SLT test
The loss-of-flame test is triggered manually with the AZL51... and produces an
interruption of the flame signal.
Using safety shutdown «Loss of flame», the LMV51... must shut the burner down.
Activation of the SLT test negates the internal controller and temperature limiter
function.

deactivated again.
