Abstract
A monitoring module for monitoring the safe operation of heat generators is proposed, which is also usable if a predominantly flameless or even completely flameless oxidation occurs in the heat generator.
Claims10
A method for monitoring the function of a gas appliance, in particular a heat generator, with predominantly flameless oxidation, having a monitoring module (93) of claim 1, characterized by the following method steps:
- detecting a first characteristic temperature (64-1) of the heat generator (83);
- comparing the first characteristic temperature (64-1) with a predetermined first limit value;
- closing a first relay (K13) if the first characteristic temperature (64-1) is above the predetermined first limit value;
- detecting a second characteristic temperature (64-2) of the heat generator (83);
- comparing the second characteristic temperature (64-2) with a predetermined second limit value;
- closing a second relay (K12) if the second characteristic temperature (64-2) is above the predetermined second limit value;
- and
- opening a main gas ramp (87) and/or a starting gas ramp (85) for supplying gas to the heat generator (83) if both the first relay (K13) and the second relay (K12) are closed.
The method of one of the foregoing claims, characterized in that at periodic intervals, the first microcontroller (106) interrupts the signal communication between the first temperature sensor (64-1) and the first amplifier and comparator (TV 1), and that the signal communications between the first temperature sensor (64-1) and the first amplifier and comparator (TV 1) and between the second temperature sensor (64-2) and the second amplifier and comparator (TV 2) are restored only if as a consequence of the signal interruption, the second microcontroller (107) also interrupts the signal communication between the second temperature sensor (64-2) and the second amplifier and comparator (TV 2).
The method of one of the foregoing claims, characterized in that at periodic intervals, the second microcontroller (107) interrupts the signal communication between the second temperature sensor (64-2) and the second amplifier and comparator (TV 2), and that the signal communications between the first temperature sensor (64-1) and the first amplifier and comparator (TV 1) and between the second temperature sensor (64-2) and the second amplifier and comparator (TV 2) are restored only if as a consequence of the signal interruption, the first microcontroller (106) also interrupts the signal communication between the first temperature sensor (64-1) and the first amplifier and comparator (TV 1).
A monitoring module for monitoring a heat generator (83) with predominantly flameless or entirely flameless oxidation, characterized in that it is suitable for performing a method of one of the foregoing claims.
