Abstract

Verfahren zur Überprüfung des Ionisationselektrodensignals einer Ionisationselektrode (14) eines Gasbrenners (1), insbesondere mit Gebläse (2), mit einer elektronischen Regelung (3), welche zu einer vorgegebenen Brennerleistung ein Sollsignal für die Brenngasmenge und die Luftmenge vorgibt, einer Einrichtung zur Regelung der Brenngasmenge (4, 5) und einem Abgassensor (6), der ein der Kohlenmonoxid-Konzentration oder Konzentration an unverbrannten Kohlenwasserstoffen äquivalentes Signal erzeugt, wobei das Brenngas-LuftGemisch angefettet wird bis der Abgassensor (6) ein Signal erfasst, das alleine oder in Verbindung mit mindestens einem weiteren Signal einem vorgegebenen oder errechneten Schwellwert entspricht, zu diesem Zustand das Ionisationselektrodensignals einer Ionisationselektrode (14) erfasst und mit einem Referenzwert oder mit mindestens einem Messwert früherer Überprüfungen verglichen wird, wobei in dem Fall, in dem das Ionisationselektrodensignals den Referenzwert unterschreitet oder mindestens einen früheren Messwert wesentlich unterschreitet, ein Warnhinweis ausgegeben wird.

Method for checking the ionization electrode signal of an ionization electrode (14) of a gas burner (1), in particular with blower (2), with an electronic control (3), which predetermines a setpoint signal for the fuel gas quantity and the air quantity for a given burner output, a device for regulation the fuel gas amount (4, 5) and an exhaust gas sensor (6) producing a signal equivalent to the carbon monoxide concentration or unburned hydrocarbon concentration, the fuel gas-air mixture being enriched until the exhaust gas sensor (6) detects a signal that is alone or in Connection to at least one further signal corresponds to a predetermined or calculated threshold value, for this state the ionization electrode signal of an ionization electrode (14) is detected and compared with a reference value or with at least one measured value of previous checks, in which case the ionization electrode signal has the reference value If at least one previous measured value falls significantly below a warning is issued.
