Commands in the event of operational interference
Stray light/premature ignition
During pre-purge and/or pre-ignition there should be no flamesignal. If
there is a flame signal, eg from premature ignition due to a faulty solenoid,
external light, short circuit in the photoresisto or wiring, malfunction in the
flame signal amplifier, etc., at the end of pre-purge and safety time the
controller locks out the burner and stops the fuel flow even during safety
time.
Absence of flame
If there is no flame at the end of safety time the controller locks out imme-
diately.
Absence of flame during operation
If there is no flame during operation the controller cuts off the supply of
fuel and automatically initiates a fresh start-up programme: at the end of
t4 the start-up programme ends.
Whenever there is a safety stop, terminals 3-8 and 11 are de-energised in
less than 1 second; at the same time a remote lockout signal is transmit-
ted through terminal 10. The controller can be reset after c. 50 seconds.
