Method for operating gas burner

The invention relates to a method for operating a gas burner, in which a voltage signal (S) of a voltage applied to an ionization electrode arranged on the gas burner is monitored, the voltage at the ionization electrode being adjusted to a target value (S0). According to the invention, when a first deviation of the voltage signal (S) from the setpoint value (S0) reaches a predetermined first magnitude ([delta] S1), the voltage signal (S) is continuously measured beyond a determined time interval ([delta] t), and generating a fault message if a second deviation of the voltage signal (S) from the setpoint value (S0) is detected as a function of the voltage curve within the time interval ([delta] t) by a predetermined second magnitude ([delta] S2). 本发明涉及一种用于运行气体燃烧器的方法，其中，监控施加在布置在所述气体燃烧器上的电离电极上的电压的电压信号(S)，其中，将所述电离电极上的电压调节到额定值(S0)。根据本发明提出，当所述电压信号(S)与所述额定值(S0)的第一偏差达事先确定的第一量值(ΔS1)时，继续测量所述电压信号(S)超过确定的时间间隔(Δt)，并且如果根据在所述时间间隔(Δt)内的电压曲线探测到所述电压信号(S)与所述额定值(S0)的第二偏差达事先确定的第二量值(ΔS2)，则生成故障信息。
