7.4 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 AZL5... and produces an
interruption of the flame signal.
Using safety shutdown «Loss of flame», the LMV5... must shut the burner down.
Activation of the SLT test negates the internal controller and temperature limiter
function.
The setpoint and the temperature limiter switch-off threshold will be ignored.
The burner will be switched on and the output automatically increased to 100 %.
After safety shutdown by STL lockout or manual selection, the SLT test can be
deactivated again.
