3.3 Behaviour during start-up 3.3.2 Start-up without flame signal Once the start-up signal (J) has been applied, the automatic burner control unit checks the burner for flame simulation during the waiting time tW. If no flame simulation is detected during that period, the safety time on start-up tSA 02 then starts to elapse (3, 5 or 10 s). This forms the minimum operating time of the automatic burner control unit and the burner. Voltage is supplied to the pilot gas valve V1 and the ignition transformer. After the safety time on start-up tSA has elapsed and the flame signal has been received,...
