7.2.1 Loss of flame
In the event of loss of flame, the unit initiates safety shutdown, followed by a restart, if
required. A repetition counter can be used to select the number of flame losses after
which the unit shall initiate lockout (refer to chapter Repetition counter).

Caution!
The response time of the flame detector leads to an extension of the second
safety time (TSA2). This must be taken into account when designing the burner!
7.2.2 Extraneous light
Extraneous light during standby (phase 12) leads to prevention of startup, followed by a
restart. Extraneous light during the prepurge phase results in immediate lockout. If
extraneous light occurs during the shutdown phase, the system switches to the safety
phase.
One repetition is permitted. This means that if the error occurs again the next time the
system is shut down, the unit will initiate lockout.
