Definitions
- the invention relates according to the preamble of claim 1, a method for setting and controlling an actuator for a burner, wherein certain actuating positions of the actuator are controlled by a firing and monitored.
- a method of the type mentioned is known for example from EP 1 215 442 Al.
- four control signals for controlling the open, Zu-, Zündlast- and small load adjustment position of an actuator by means of a diode network and two relays from the burner control via a control line to the actuator, with corresponding feedback signals for position detection of the actuator via a Feedback line to be routed to the burner control.
- the automatic burner controls the actuator.
- the automatic burner generates a release signal for a power controller, which then controls or regulates the open or closed position of the actuator during burner operation.
- the power control signal is set before the start of the burner to the working range of the actuator and in the burner operation takes place in the actuator an analog signal evaluation of the control signal. Consequently, the known method for actuators without appropriate analog signal processing can not be used.
- the invention has for its object to propose a method which allows easy adjustment of the working range of the actuator and automatic determination of the control parameters for the work area, the adjustment and control of the actuator should be possible with little effort.
- the object underlying the invention is solved by the features of claim 1.
- the invention is characterized in that before starting up the burner, a minimum and maximum setting position of the actuator, which define the working range of the actuator by means of
- Setting elements is set and that the automatic control unit in the control of the actuator monitors the set minimum and maximum control position by corresponding feedback signals while position signals are obtained from a position sensor, which are dependent on the control position reached in the actuator and that the automatic burner in the Feedback of the minimum actuating position of the actuator detected position signal assigns the minimum actuating position and that detected in the feedback of the maximum actuating position of the actuator
- standard position values are used by the automatic burner control to control the minimum and maximum actuating position, which are stored in the burner control unit before the burner is put into operation. Thereafter, the control parameters determined from the position signals are used to control the minimum and maximum control positions of the automatic burner control.
- the automatic burner control determines new control parameters from the position signals. Even if no feedback signals are received with the new control parameters, the automatic burner control system generates an error message and / or initiates a
- the automatic burner control compares the currently obtained position signal with a setpoint signal. Depending on the difference between the position signal and the setpoint signal, the automatic burner control generates an actuating signal for the actuator.
- a power controller Preferably, a power controller generates the setpoint signal, which is evaluated by the automatic burner control for controlling or regulating the actuator accordingly.
- the firing automat knows a memory, for example, an EEPROM for storing the standard position values and the control parameters and corresponding signal inputs for the setpoint, feedback, and position signals.
- the invention has the advantage that a standard actuator without analog signal conditioning can be used. Due to the fact that the burner control unit permanently monitors the minimum and maximum setting position of the actuator during burner operation, a drifting away of the position signal can be detected by the automatic burner control and corrected accordingly. A manual readjustment of the set work area is not required.
- FIG. 1 shows in a functional block diagram of the invention.
- the figure shows a schematic representation of an actuator 1, an automatic burner 5 and a
- the actuator 1 comprises an electric motor 2, adjusting elements 3 and a position sensor. 7
- the operating range of the actuator 1, d h. set the minimum and maximum setting position, for example by switching cams not shown here.
- standard position values for actuating the actuator in the automatic burner 5 are stored before the burner is put into operation.
- the automatic firing unit 5 generates, for example based on the standard position values corresponding control signals 6 for controlling the set minimum and maximum control position of the actuator 1.
- the control cams actuate the minimum or maximum control position associated switch 3, whereby corresponding feedback signals 4 are obtained.
- the automatic burner 5 detects the case thereby received from the position sensor 7 position signals 8.
- the position sensor 7 is z. As a potentiometer, which provides a position signal 8, which changes proportionally with the setting position of the actuator 1.
- the automatic burner 5 assigns the detected during the feedback of the minimum actuating position of the actuator position signal 8 of the minimum setting position. Accordingly, that detected in the feedback of the maximum setting position position signal 8 of the maximum setting position assigned. From the position signals 8 assigned to the minimum and maximum setting positions, the automatic firing unit 5 determines corresponding control parameters for controlling the minimum and maximum setting positions and stores the control parameters.
- the determination of the control parameters by the automatic burner control can take place when the burner is put into operation and / or in burner operation, with the automatic burner control unit correspondingly monitoring the switches 3 and the acknowledgment signals 4.
- the automatic burner control unit 5 controls the actuator 1 independently of a power controller 10.
- the power controller 10 In burner operation, the power controller 10 generates a setpoint signal 9, which is evaluated by the automatic burner control 5 for controlling or regulating the actuator 1.
- the automatic burner 5 compares the setpoint signal 9 obtained from the power controller 10 with the currently obtained position signal 8 and generates a corresponding control signal 6 for the actuator 1 as a function of the difference between the position signal 8 and the setpoint signal.
- the power controller 10 is shown as an independent functional unit. However, the function of the power regulator can also be integrated in the firing automat 5.
- the automatic firing unit 5 determines the corresponding control parameter and saves it. In the event that even with the corresponding newly determined control parameters no feedback signal 4 is obtained, the automatic burner 5 generates a corresponding error message and / or causes a safety shutdown of the burner.
