During burner off times, the flame supervision circuit is live.
Lockout indication
a-b Startup sequence
b-b’ Idle step (with no contact confirmation)
b(b’)-a Postpurge program
Burner control can immediately be reset after lockout:
Do not press the lockout reset button for more than 10 seconds
The sequence switch always travels to the start position first
After resetting
After rectification of a fault that led to shutdown
After each power failure
During this period of time, power is only fed to terminals 7 and 9...11.
Then, the LAL.... will program a new burner startup sequence
