Definitions
- the invention relates to a control device for a burner with two control units with which one or two valves arranged in series with one another in a path of a combustion medium can be controlled for opening and blocking the path and with which state data indicating the switched-on state and the blocked state of the valves can be recorded and further control functions for the operation of the burner can be carried out.
- the invention is based on the object of providing a control device of the type mentioned at the outset which fulfills the required security and is constructed in a relatively simple and inexpensive manner.
- the functions are differentiated according to safety-relevant functions, which include at least the activation of the valve (s) for assuming the blocking state and the recording of the state data indicating the blocking state, and further functions, including the recording of a heat demand and count the ignition of the burner, and that the safety-relevant functions are assigned to the two control units, while only partial quantities of the other functions are assigned to the two control units.
- safety-relevant functions include at least the activation of the valve (s) for assuming the blocking state and the recording of the state data indicating the blocking state, and further functions, including the recording of a heat demand and count the ignition of the burner
- control processes and thus also the structure of the control device can be further simplified in that the subsets of the further functions by means of an encoder and / or by means of parameters of a superordinate one Control program can be variably adjusted or expanded or reduced.
- the memory and data transmission elements do not have to be designed to always be able to carry out all possible functions, but rather the effort with regard to the possible functions that may occur can be minimized, the versatility of the setting options being retained.
- the variety of setting options is further favored by the fact that the safety-relevant functions and the further functions can be set on the basis of different options, which include at least two of the following setting options: one or two valves are present, the valves are each only from one control unit in parallel or each can be controlled by two control units; an additional switch-off relay is available or not; an additional control processor is present or not; the data exchange with the additional control processor takes place via a positive or negative logic.
- the safe functioning of the control device is supported in that a data exchange takes place between the two control units and in that the two control units mutually relate to one another with regard to their states and
- control device is further favored in that a control unit is assigned a higher priority than the other control unit, in that only the control unit with the higher priority has a heat is supplied and a writable and erasable non-volatile memory is assigned, with which this control unit communicates, and that this one control unit forwards the heat demand and data read from the non-volatile memory to the other control unit.
- the one valve or the two valves in series in the path of the combustion medium can each be controlled via two semiconductor switches in series in a valve control
- Valve / the valves can already be / are brought into the blocking state by controlling only one of the two respectively assigned semiconductor switches, and that the two control units for controlling the valve / the valves each with one of the two semiconductor switches assigned to a valve - in the presence of two valves cross-connected - with a simple structure, a high level of safety is achieved when controlling, in particular a gas supply.
- the figure shows a schematic representation of a control device for a gas burner, a first valve V1 and a further valve V2 being arranged in series in a gas supply path as safety valves, via which the gas is led to the burner.
- the first valve V1 and the second valve V2 are by means of a first control unit C 1 and a further control unit C2
- Both control units C1, C2 act on a first valve control A1 assigned to the first valve V1 and a further valve control A2 assigned to the further valve V2 with control data for opening or blocking the two valves V1, V2.
- the first control unit C1 is connected to the first valve control A1 via a control line SL1 and to the further valve control A2 via a further control line SL2, while the second control unit C2 is connected to the first valve control A1 and a further control line SL2 'via a control line SL1' the other
- Ventiian control A2 is connected.
- the two control units C1, C2 are connected via respective return lines RL1, RL2, RL1 'and RL2' via a first evaluation circuit M 1 assigned to the first valve VI and a further evaluation circuit M2 assigned to the further valve V2, by 5 the switch-on state and the blocking state of the two valves VI and V2.
- the two control units C1 and C2 exchange data relating to their respective states and other data important for both control units via a data bus.
- the first control unit C1 is in a mutual data exchange with a writable and erasable non-volatile memory SP in the form of an EEPROM.
- An unlocking signal of an unlocking E is fed to both control units C1, C2.
- both control units C1, C2 receive signals from an ionization or flame detection for a flame test.
- a coding K different options, such as. B. the presence of one or two safety valves, a crossed or parallel control of the two valve controls A1, A2, the presence of an additional switch-off relay R, control with or without an additional control processor ST, data exchange via positive or negative logic with the 0 Control processor ST, set and other options, such as a safety time and a switch-off time for a leak test.
- the other control unit C2 is also assigned the ignition Z of the burner.
- a relay REL connected to both control units C1, C2 is used for error monitoring and additional switch-off options.
- a (controllable) temperature limiter B is provided for the control of the valves V1, V2 or the evaluation circuits M 1, M2 assigned to them.
- the section of the control device described above belongs to one
- This circuit section is connected to a peripheral I via a corresponding interface.
- the periphery I has the control processor ST already mentioned, which is in data exchange with the first control unit C1.
- the control processor ST via which a heat demand is also supplied and z.
- B. a fault display or burner-on display can be effected the periphery I has a control section SA, with which the heat demand WF, the fault display can be controlled via a LED 1 and the burner-on display via a LED2 .
- the periphery also has a supply V for the control device.
- the valve controls AI, A2 of the two valves V1, V2 are operated crosswise by means of the two control units C 1, C2.
- the valve controls A1, A2 each have two separate switches in the form of semiconductor switches, which are preferably different, for. B. constructed as a bipolar transistor or field effect transistor and are controlled with different logic.
- the two control units C1, C2 are each assigned to a different switch. Pressing one of the two switches assigned to a valve is sufficient to block the gas supply path. Thus, the gas supply can also be blocked by only one of the two control units C1, C2 if one of the two control units fails.
- the information of a failure of the two control units C1, C2 is received by the other Control unit from the query of the evaluation circuit M1 or M2 and / or the data exchange between the two control units C1, C2.
- the data exchange between the two control units C1, C2 takes place via a serial interface, the data containing at least all safety-relevant data for controlling the valves V1, V2, which are compared with one another.
- At least one control unit Cl, C2 interrupts the voltage supply to the valves V1, V2 via the shutdown relay R and thus closes the valves V1, V2.
- the control unit C1 causes the error data to be stored in the memory SP.
- Both control units C1, C2 know the states of the valves V1, V2, the flame detection FE or the flame monitoring and the unlocking E or interference suppression. Only the control unit C1 receives the heat demand signal WF.
- control unit C1 When the control device is operating, the control unit C1, for example, begins communication with the control unit C2 and with the control processor ST connected via a serial interface. The respective communication partner replies after receiving the data from the control unit C1. Communication with the control processor ST can take place with positive or negative logic, depending on the processor type. Only the control unit C1 communicates with the memory SP, so that it has a higher priority than the control unit C2. The memory SP can be integrated in the control unit C 1.
- the input signals are two control units
- control unit C1 When control unit C1 receives a heat request WF from peripheral I, it forwards it to control unit C2 via the data bus. A change of state is carried out by both control units C1, C2 on the basis of the input signals. This is also an essential part of the mutual
- control units activate their respective sub-functions, such as ignition, flame test, leak test when switching off and displaying the respective state.
- the coding of the different options must be read in by both control units C 1, C2 because of the mutual monitoring.
