Definitions
- Such a control device for a burner is described in DE 195 07 071 and DE 195 07 073 A1.
- the burner is a Gas burner, and in the gas path two valves are arranged in series, the each controlled by two semiconductor switches of different construction, around each of the two valves with both one and the other Switch off semiconductor switch, d. H. to be able to block the gas path.
- the switching reliability is increased.
- Both switches of a valve is assigned to a control unit and the two switches of the other valve is a separate second control unit assigned.
- the control units receive data on the switching state of assigned valves and can thereby determine that the switch on a have corresponding control signal actually blocked the valves or Not.
- the safety of the control device is increased by the fact that the two switches each valve are differently constructed semiconductor switches, and continue in that the two switches per valve have different ones Control logic can be controlled. Due to the different structure the semiconductor switch and / or the control logic is the probability of failure significantly reduced.
- the functional reliability is further increased by the fact that all switches cyclically be checked for their switching behavior.

Claims (4)
- Steuereinrichtung für einen Brenner mit zwei in Reihe zueinander in einem Zuführzweig für ein Brennmedium angeordneten Ventilen (V1, V2) und mindestens zwei in Reihe zueinander angeordneten Schaltern (S1, S1'; S2, S2') pro Ventil (V1, V2), die von zugeordneten Steuereinheiten (C1, C2) zum Schließen und Öffnen angesteuert werden, wobei den beiden Steuereinheiten (C1, C2) Daten (DV1, DV2) über einen Schaltzustand der Ventile (V1, V2) zugeführt sind,
dadurch gekennzeichnet,
das die erste Steuereinheit (C1) sowohl zur Ansteuerung eines der beiden Schalter (S1) des ersten Ventils (V1) als auch eines der beiden Schalter (S2') des zweiten Ventils (V2) und die zweite Steuereinheit (C2) zur Ansteuerung des anderen Schalters (S1') des ersten Ventils (V1) und des anderen Schalters (S2) des zweiten Ventils (V2) ausgebildet ist und dass den beiden Steuereinheiten (C1, C2) Daten über den Schaltzustand sowohl des einen Ventils als auch des anderen Ventils zugeführt sind. - Steuereinrichtung nach Anspruch 1,
dadurch gekennzeichnet, dass die beiden Schalter (S1, S1' bzw. S2, S2') pro Ventil (V1 bzw. V2) jeweils unterschiedlich aufgebaute Halbleiterschalter sind. - Steuereinrichtung nach einem der vorherigen Ansprüche,
dadurch gekennzeichnet, dass die beiden Schalter (S1, S1' bzw. S2, S2') pro Ventil (V1 bzw. V2) über jeweils verschiedene Ansteuerlogiken angesteuert werden. - Steuereinrichtung nach einem der vorherigen Ansprüche,
dadurch gekennzeichnet, dass alle Schalter (S1, S1', S2, S2') zyklisch auf ihr Schaltverhalten überprüft werden.
