WAY (E) FOR CARRYING OUT THE INVENTION

1 shows schematically a protective housing 1 .1, in particular a protective housing 1 .1 for an electric drive of a valve for regulating the flow of fluids in HVAC systems (HVAC valve), for example a damper drive of an HVAC system. The protective housing 1 .1 has a gas-permeable membrane 1 .2, which is arranged for example in a recess 1 .3 of the protective housing 1 .1. As shown schematically in Figure 1, a protective grid 1 .4 provided to cover the recess and to protect the gas-permeable membrane mounted therein from mechanical effects. The protective grille 1 .4 can for example be screwed to the protective housing 1 .1. By using the gas-permeable membrane 1 .2 in the protective housing 1 .1 the formation of condensation or the accumulation of moisture can be prevented inside the housing. This is based on two effects: Temperature fluctuations cause expansion or contraction of the air within the protective housing 1 .1. In a hermetically sealed protective housing 1 .1, a negative pressure could develop without the gas-permeable membrane 1 .2, which draws moisture into the housing interior, for example due to age-related or construction-related defects in the sealing system, eg a brittle sealing rubber. This can for example be the result of Temperature differences between the ambient air and the housing interior. The gas-permeable membrane 1 .2 is a gas connection between the Gehäu- men and the environment. As a result, the moisture content of the air in the protective housing and the ambient air equalize, whereby in the interior of the housing accumulation of moisture is avoided.

Figure 2a-c shows schematically a load torque lock of a drive, in particular an electric drive of a valve for controlling the flow of fluids in HVAC systems (HVAC valve). The load torque lock is designed as an automatically switching clutch, with which a torsional moment in a direction of force flow is transferable, but moments are blocked from the opposite direction. If the drive is stationary and a load at the output tries to guide a restoring torque in any direction of rotation through the drive train, the load torque lock blocks. Restoring forces are thus not forwarded and the set position is retained. The arrangement according to Figure 2a-c has a motor-side drive wheel 2. 1 in the form of a hollow shaft on which an inwardly facing cam 2.1 1 is arranged. In the drive wheel 2.1, a driven gear 2.4 is arranged, which is also referred to as a ratchet wheel. The driven gear 2.4 has a groove. In driven gear 2.4 a blocked form-locking pin 2.3 is arranged with an adjacent coil spring 2.2. Angled ends of the wrap spring 2.2 protrude into the groove of the driven wheel 2.4, wherein the cam 2.1 1 is located between the protruding ends of the wrap spring 2.2. Figure 2a shows a perspective view of the wrap 2.2. FIG. 2b shows a cross section through the arrangement with the drive wheel 2.1, the wrap spring 2.2, the interlocking pin 2.3 and the driven wheel 2.4. Figure 2c shows a perspective view of the wrap 2.2, which is arranged on the form-locking pin 2.3. The drive wheel 2.1 is provided for connection to a motor. If a torque acts on the drive wheel 2.1 from the engine, is solved by the cam 2.1 1 biased on the form-locking bolt 2.3 Schlingfelder 2.2 opposite to their winding direction on the angled end with little friction and can rotate freely. If a torque from the output gear 2.4 acts, the wrap is pressed in the winding direction over the bent end of the form-locking bolt 2.3 and blocked by frictional engagement. As a result of the both sides angled ends of the wrap spring 2.2, this works both from the drive and the output side in both directions of rotation. The changeover takes place without loss of travel and the locking is controlled independent of direction from the output side. In one embodiment, a drive, in particular an electric drive of a valve for regulating the flow of fluids in HVAC systems (HVAC valve), for example a damper drive of an HVAC system, comprises a gear stage with a characteristic adaptation. In contrast to normal gear stages with a fixed gear ratio gears are provided with specially shaped gears and / or gears, in particular to change the ratio with the rotation of the gears, which therefore change, for example, the transmitted torque, the angle of rotation and the rotational speed. Thus, the damper drive can be optimally dimensioned to a specific application, for example to obtain an increased torque at the stop, in certain positions a reduced rotational speed or other desired properties. The increased torque makes it possible, for example, to provide smaller sized and therefore cheaper drive motors. For example, a reduced rotational speed results in a more precise adjustment or regulation of a valve position. 3 schematically shows an arrangement with a drive 3. 1, in particular an electric drive of a valve for regulating the flow of fluids in HVAC systems (HVAC valve), for example a flap drive of an HVAC system, and a flap shaft 3.2 with a square profile, which is inserted into a hollow shaft 3.3 of the drive 3.1. The flap shaft 3.2 is provided, for example, to change the position of a ventilation flap. To create a positive connection between the valve shaft 3.2 and the hollow shaft 3.3 of the drive 3.1 form-locking inserts 3.4, 3.5 are provided. The positive locking inserts 3.4, 3.5 have on the outside, for example, a splined shaft profile, which interacts with a splined hub of the hollow shaft 3.3 of the drive 3.1 positive fit. The form-fitting inserts 3.4, 3.5 are hollow inside and have on the inside of profiles which are suitable for the positive cooperation with, for example, a flap shaft 3.2 are provided with a square cross-section or with a crescent-shaped cross-section. The positive locking inserts 3.4, 3.5 are in particular designed such that a safe entrainment of the valve shaft 3.2 results and a centric attachment of the drive 3.1 is possible. In the case of centric mounting, the drive 3.1 can be fastened firmly to the base, for example as shown schematically in FIG. 3 with screws 3.6, 3.7. In particular, the drive 3. 1 is plugged directly onto a flap shaft 3.2, which projects, for example, out of a ventilation tube and is connected to a ventilation flap for regulating an air flow. After attaching to the valve shaft 3.2, the drive is for example screwed directly onto the ventilation pipe. The reaction torque, which results in the operation of the drive 3.1 and the movement of the valve shaft 3.2 with an attached air damper, is absorbed by the screws 3.6, 3.7, wherein there is a rotation. If the rotation prevents longitudinal movement, ie if, for example, guide slots are provided on the drive housing and thus a Longitudinal movement is possible, then can the flap shaft 3.2 mounted in the hollow shaft 3.3 also eccentric.

Figure 4 shows schematically an arrangement with a clamping block 4. 1, to a torque between a drive, in particular an electric drive of a valve for controlling the flow of fluids in HVAC systems (HVAC valve), such as a damper actuator of an HVAC system, and a To transfer flap shaft.

The holder 4.4 has, for example, a splined hub, which is provided for the torque-locking connection with a spline of the drive, wherein a torque transmission between the holder 4.4 and the drive is created. As can be seen from Figure 4, locking means such as nuts in particular 4.5, 4.6 are provided to see between the clamping bracket 4.2 and the clamping element 4.3 to create a clamping force, so that the clamping bracket 4.2 and the clamping element is clamped to the valve shaft. By a corresponding shaping of the clamping bracket 4.2 and the clamping element 4.3 as well as by a corresponding choice of material and / or treatment of the clamping bracket 4.2 and the clamping element 4.3 can for very different valve waves, i. Especially for different geometries and / or different materials, a secure non-positive torque transmission be created between a flap shaft and the clamping block 4.1 and thus the drive.

The clamping bracket 5.2 and the clamping element 5.3 are arranged in a holder 5.4 and are tightened by locking means such as in particular nuts 5.5, 5.6, to create a non-positive torque transmission to a flap shaft 5.7. The clamping block 5.1 is also connected in a torque-locking manner to a drive whose drive housing 5.8 is shown in detail in FIG. As shown by the different shades, the clamping block 5.1 allows a frictional torque transmission to flap shafts 5.7 different geometries, such as to flap shafts with a cross-section of round, square, hexagonal, octagonal, etc. is. Accordingly, the clamping bracket 5.2 and the clamping element 5.3 are formed such that a non-positive torque transmission can be made to round flap shafts with a variety of diameters and square, hexagonal, octagonal, etc. flap shafts of different key widths.

The clamping block 6.1 has a clamping element 6.3, which as described with nuts 6.5, 6.6 and a clamping bracket cooperates to produce a non-positive torque transmission to a valve shaft. The clamping element 6.3 has, for example, as shown in Figure 6 schematically a staircase-shaped profile to center flap shafts of different diameters and clamp in cooperation with the clamping bracket. The clamping element 6.3 is, for example, by sintering as Sintered insert produced. By sintering, low-cost materials can be produced, resulting in hard materials and sharp and accurate contours are malleable.

The clamping block 1 3.1 is used as described above in a hollow shaft of a drive with the drive housing 1 3.8 shown schematically. The clamping block 1 3. 1 has a mechanical interface 1 3.1 7, to which a position indicator 1 3. 1 9 is fastened. The position indicator 1 3.1 9 is provided for attachment to any other base element instead of the clamping block 1 3.1. The position indicator 1 3.1 9 is rotatably mounted, so that the pointer 1 3.20 can be brought into any rotational position. The pointer 1 3.20 has in particular fluorescent properties to improve the visibility of the position indicator 1 3.1 9.

Figure 14 shows schematically a position indicator 14. 1 9, which is placed on an auxiliary device 14.1 8. The auxiliary device 1 4.1 8 is provided in particular as described to produce a mechanical interface 14.1 7 a torque-locking connection with a clamping block, wherein the clamping block is provided to a torque between a drive, in particular an electric drive of a valve for controlling the flow of To transfer fluids in HVAC systems (HVAC valve), such as a damper actuator of an HVAC system, and a flap shaft. As in figure 14 schematically shown, the patch on the auxiliary position indicator 14.1 9 a pointer 14.20, which indicates the rotational position of the position indicator 14.1 9. The auxiliary device 1 4.1 8 is for example an additional switch, the position indicator 14.1 9 is snapped in a hollow shaft of the auxiliary switch. The position indicator 14.1 9 can be rotated in particular as desired.

For the axial coupling of valve and drive, an additional installation effort is required, which can be reduced by a coupling according to Figures 24a-c and 25a-c. Figure 24a shows schematically 3 claws 24a.1, which have an internal geometry corresponding to the shape of the valve and drive spindle. FIG. 24b shows a clamping strap 24b.1, for example made of plastic, which responds to the contraction or release of the 3 jaws 24a.1 to the valve resp. Drive spindle is set up. The clamping ring additionally has 4 hooks, which are provided for locking the clamping strap to the coupling lock 24c.1 shown schematically in Figure 24c. The coupling lock 24c.1 according to FIG. 24c is, for example, made of plastic and is set up for coupling the clamping clip 24b. 1 via the corresponding hook and for an additional radial positive connection between the coupling and the holding elements. Figure 24c shows a mounting ring 24c.1, which is made for example of plastic, with which the claws 24a.1 can be held for assembly purposes or for shipping the clutch. The coupling according to FIGS. 24a-c and 25a-c is dimensioned, for example, for tensile and / or compressive forces of up to 10 kN, whereby a cardanic suspension is provided which permits an angular offset between the valve and the drive spindle.

The axial coupling according to Figures 24a-c and 25a-c is adapted for coupling a valve with a linear drive, wherein the drive and valve spindle with a defined annular groove are provided and the clutch claws, a clamp and a coupling lock has. In one embodiment variant, the coupling for penetrating the drive and valve spindle has at least 3 metallic claws displaceable in the radial direction. In one embodiment, the coupling includes a flexible clamping strap, which is preferably made of plastic, which includes the jaws, and is held in the production mounted state by retaining claws in the radial direction of the coupling lock. In one embodiment, the plastic clamping strap for the radial engagement of the jaws in the grooves of the drive and valve spindle in the manner of clamping is locked. In one embodiment variant, the coupling lock is axially displaceable on the clamping strap and the coupling lock has an inner cylindrical diameter which corresponds to the outer cylindrical diameter of the (at least) 3 claws, the coupling lock enclosing the claws during axial displacement and thus fixes the coupling in the radial direction. In one embodiment, the clamping strap has at least two retaining claws, which engage in the displacement of the coupling lock in this, the coupling is thus held together with the retaining claws in the radial direction and in the axial direction. In one embodiment, in the closed coupling state, the claws enclosing the groove or annular groove of the drive spindle due to a conical surface and the claws surrounds the groove or annular groove of the valve spindle with a short contact surface, see between drive and valve spindle a gap, wherein an angular offset zwi ^¬ rule drive and valve spindle, without axial clearance between the drive and valve spindle, is possible. In one embodiment, the coupling lock on a transverse extension, the end of which ends in a semicircle and engages in the drive console and serves as a position indicator. In one embodiment, an assembly aid is provided in the form of a plastic ring and centrally arranged cylinder of the Claws in an open state holds so that the clutch during production, in the field or during transport can be easily pushed through the drive spindle.

A linkage makes it easy to connect a drive to a valve. The following connection principles are available: Torque transfer via cams or another positive connection between the drive and the valve, where axial securing is provided by means of a central screw or a quick coupling such as a snap ring, form fit, etc .; Torque transmission by adhesion in which by means of screws pressing on the valve neck takes place and so a non-positive torque transmission is created. If the same drive with different interfaces, which are for example referred to as F04 / 05/06, etc., to be coupled, then in a variant of a universally usable insert plate is used with which a coupling is made possible on different interfaces. In one embodiment variant, the drive / linkage interface is standardized and various linkages, that is to say in particular positive connection and traction linkage, can be coupled to the same drive. This allows a modular design. In one embodiment, the linkage is part of the drive floor, which no separate linkage is required. In one embodiment, a linkage comprises a hand lever, which is used to adjust the valve in the de-energized state. In one embodiment, the hand lever has the function of a tool such as a hexagon or a Imbus- factory tool. In a further embodiment, the hand lever is clipped or looped on a cable of the drive, in particular in the sense of a captive. In one embodiment, a rotary ring is provided for the rotation angle flow restriction. In a further embodiment variant, a cover can be mounted on the linkage, which aid in particular in setting the flow. In one embodiment, a driver is configured such that a wrong mounting on the valve is prevented. In one embodiment, the device for preventing a false assembly is removable. In one embodiment, the clearance between the valve and the drive is optimized and guarantees optimal functioning of the drive and the valve.

In one embodiment, a drive of an HVAC system, in particular an electric drive for adjusting a valve for controlling the flow of fluids in HVAC systems (HVAC valve), for example for setting a ventilation flap, a drive electronics, which in the usual way, for example a circuit board is soldered and includes electronic components, with which one or more of the drive functions described below are provided. In addition to electronic components, the drive electronics have, for example, a programmable microprocessor which is set up to provide drive functions which are specified in accordance with software programs that can be run on the microprocessor.

The drive electronics of the drive is for example a power saving mode Ver ^¬ addition, to cause a current reduction at the stop, so that unnecessary energy is not consumed, and the components are protected. To detect the stop ^wer¬ tet the drive ^¬ electronics, for example, a current measurement of the drive motor. As soon as a stop position is reached, the current supplied to the drive motor increases. In one embodiment, the ripple of the drive motor ^{¬ supplied} current is determined. The ripple is due to commutation and missing as soon as the stop is reached. In another embodiment, the current measurement is combined with the determination of the ripple. In an execution variant Ante is provided by means of an NTC resistor (NTC: Negative Temperature Coefficient) a temperature profile correction and a demand-based current limit. In one embodiment variant, the drive electronics are set up to lower the drive current after a time interval. In another embodiment, the drive electronics is configured to lower the drive current to zero and thereafter perform a restart strategy by stepping the drive current, for example, to conserve the drive motor or associated drive components. In another embodiment, the reduction of the drive current is load-dependent. Depending still flap position are different torques required for the movement of the flap, for example, due to gravity.

The drive electronics of the drive, for example, a control signal control available. Thus, for example, the inputs for a triac (Triode for Alternating Current) have an impedance changeover, wherein in one embodiment a current measurement takes place by, for example, controlling whether a minimum current flows in order to then decide whether the input signal is active or not. For this purpose, the drive electronics are designed, for example, with or without ASIC (Application Specific Integrated Circuit). In an embodiment variant, the drive electronics comprise a V control (V: speed), wherein the drive is moved faster the greater the difference between a desired value and an actual value. In one embodiment, the drive electronics comprise a converter for currents of, for example, 4... 20 mA, for example, a 5000hm resistor being provided, as well as a voltage of, for example, 2... 1V, which together offer a universal control possibility. The drive electronics of the drive provides, for example, an inhibition torque increase. Thus, the drive electronics is set up to brake the drive motor by short circuit, for example by shorting a Vierquadrantstellers such as an H-bridge. In one embodiment variant, the drive comprises a drive motor with a high cogging torque for the escapement or a high holding torque at standstill. In one embodiment, a Rastmomentblech is provided to provide a high cogging torque in the drive motor, as described for example in WO 201 1/047488.

The drive electronics of the drive provide, for example, an electronic rotation angle limitation, in order not to drive into mechanical stops and not unnecessarily burden the drive or unnecessarily reduce its service life. In one embodiment variant, the drive electronics are set up to set a minimum or a maximum angle. In one embodiment, the drive electronics is adapted for angular adaptation, which is, for example, capable of learning and recognizing at which positions there are stops, for example, traversing intermediate positions faster than the positions in the area of the stops, so as to limit the mechanical stress.

The drive electronics of the drive, for example, an internal supply available, which is activated in a drive with return spring in the case of a spring return. The maximum internal supply voltage is limited by Z-diodes or a Transzorb. By providing an internal supply, electronic components required for the return of the drive are functional. For example, in the event of a power failure, it is possible to ensure a return which is controlled by the drive electronics. In one embodiment, the drive is designed as a spring return drive, which provides an asymmetrical torque distribution in the two drive directions available. In particular, the torque provided by the motor for mounting or opening is greater than the torque provided by the spring return. Tight closing flaps, such as in a cold gas or lip seal, for example, require a higher torque for opening due to the energy required for folding the seal than for closing. In one embodiment, the nominal torque is increased by approximately a factor of 3, for example, with an optimized linkage when closing, while the rated torque is reduced, for example, by a factor of approximately 0.8 when opening. In single-leaf flaps, which have only one sheet, an additional torque in the closing direction takes place due to aerodynamic forces in the flow-through channel and gravity. This also applies to multi-leaf flaps in attenuated form, with no additional torque due to gravity. The drive electronics of the drive has, for example, devices for increasing the robustness of application. In one embodiment, the drive electronics is set up to perform a setpoint measurement, for example, at a Y input (control signal input) at the zero crossing, wherein long lines are compensated and the line resistance is hidden. With long lines, which inevitably lead to a greater line resistance, a large current reference, that is to say a single drive with a high power or with several drives connected to the same supply, also causes a voltage drop on the neutral conductor, ie Gnd. This voltage drop would affect the measurement of the desired signal. With a measuring device such as an ASIC or a microprocessor, the phase position of the supply can be detected and the actuating signal, ie an applied DC Signal in the range of, for example, 0 ... 10V, measured only during the zero crossing of the supply. During the zero crossing, the current is also zero and thus does not influence the measurement of the actuating signal. This drives the drive to exactly the position specified by the actuating signal. This procedure works with an AC supply.

The drive electronics are provided, for example, for connection to an MP bus (multi-point), wherein the MP terminal of the drive electronics is set up to effect a disconnection in the event of a false connection. Next, the drive electronics, for example, malfunction-safe inputs and outputs. In one embodiment, the drive electronics is set up to block a temperature shutdown in the event of high ambient temperatures such as a fire and thus to ensure the functionality of the drive, for example in a dangerous situation such as a fire.

The drive electronics of the drive has, for example, devices in order to ensure a uni-verse supply, for example in the range of 24V ... 240V. Instead of different transformers, such as transformers that cover the range of mains voltages from 100V ... 240V, the drive electronics have switching regulators or switched power supplies which cover mains voltages in the range of eg 85V .... 265V. This results in a cost-effective coverage of a wide range of mains voltages. As shown in Figure 1 5, a switching regulator 1 5.1 in one embodiment, a charge-based on an active Graetz circuit charge pump with a Schmitt trigger. In another embodiment variant, the switching regulator has a charge pump based on an active Graetz circuit with a clock from a microprocessor, wherein no Schmitt trigger is to be provided. A capacitor feed allows a inexpensive solution. The capacitor feed may be in the case of an AC supply, for example at 50Hz or 60Hz, and is mostly limited to low power application. A capacitor operated with an AC voltage develops a low-loss forward resistance or reactance in accordance with the capacitance value and the frequency. As a result, a much lower supply voltage can be generated from a high mains voltage of, for example, 230 VAC by means of this series resistor, for example 24 VAC. With a rectifier, such as a diode or a bridge rectifier, and another capacitor can be generated in a very simple manner, a DC supply voltage of, for example, 24VDC, which can be used for drives, etc. In one embodiment, the supply has a special switching regulator with integrated maximum current limit, whereby the torque is limited and thus the mechanics is protected. In one embodiment variant, the generation of a 24VDC supply voltage takes place via the conversion of an unsmoothed AC mains voltage. In one embodiment variant, a drive, in particular an electric drive of a valve for regulating the flow of fluids in HVAC systems (HVAC valve), for example a damper drive of an HVAC system, has an MFT functionality (MFT: Multi Functional Technology). For example, a drive with an MFT functionality can be set up to provide several different types of control, which can be determined when using the drive. A type of control relates, for example, to constant control with a continuous control signal, the position of the drive being set in proportion to a control signal at the Y input of the drive, ie a control signal input. This very often used control is also called SR / SRS control. The drive signal can, for example, a value of 0V ... 1 0V, 0.5V ... 10V, 2V ... 1 0V or from a have another range, wherein the drive position is set according to a value of 0 ° ... 360 °, from 0 ° ... 180 ° or in another range. Another type of control relates, for example, to a 3-point control, whereby, for example, a 3-point switch can be switched between 3 positions. This control is also referred to as 3-point control. On one of the positions, a maximum position of the drive is approached, on a further position, the drive is brought to a standstill and in yet another position, a minimum position of the drive is approached. Another type of control relates, for example, to a 2-point control, wherein, for example, a 2-point switch can be switched between 2 positions. The drive is opened in one of the positions and brought to the OPEN position. In the other position, the drive is closed and brought to the TO position. Another type of control relates, for example, to a PWM control (PWM: Pulse Width Modulation), wherein the drive position is set according to a PWM signal. This control is also referred to as PWM control. For example, the PWM signal may range from 0.59s ... 2.93s or any other range.

Another MFT functionality of a drive, in particular an electric drive of a valve for regulating the flow of fluids in HVAC systems (HVAC valve), for example a damper drive of an HVAC system, can affect the sensor connection. The drive has interfaces for the connection of sensors such as sensors for humidity, temperature as well as monitors and switches. The corresponding sensor signals are detected by the drive and converted into a bus-capable signal, for example into a signal according to the MP standard. As a result, simple, inexpensive sensors can be used, whereby the cabling effort is significantly reduced. The use of bus-capable, expensive sensors can be avoided. Another MFT functionality of a drive, in particular an electric drive of a valve for controlling the flow of fluids in HVAC systems (HVAC valve), for example a flap drive of an HVAC system, concerns the allocation of priorities in the interaction of analog control signals which are connected to a Y-axis. Input or control signal input are applied, from P commands, which are transmitted on an MP bus, of forced controls, of forced circuits, of compulsory functions, of manual control operations and of other functionalities. In a forced control, the applied control signal is overridden by a positive control. In a forced circuit, forced signals such as GND (ground), 24VAC signal, positive or negative half wave are used, which are detected at the Y input ie at the control signal input as a forced circuit. These compulsory circuits or forced signals can be assigned different compulsory functions, such as a forced function "fast opening", a compulsory function "quick closing" or another compulsory function. By assigning priorities, a meaningful function of the drive is guaranteed. For example, analog forced signals may be assigned higher priorities than MP functions, so that when the drive is controlled locally via MP commands, a functional test can be performed by means of analog forced signals. The priorities can also be allocated so that a through MP commands triggered forcing function such as the "quick opening" or "rapid closure" has a higher priority than analog force signals so that, for example, in case of fire by the Central a useful ^¬ full Drive position is specified, which can not be changed on site, for example, in a functional test.

Another MFT functionality of a drive, in particular an electric drive of a valve for regulating the flow of fluids in HVAC systems (HVAC valve), For example, a damper actuator of an HVAC system, relates to the types of control. The drive can be prepared to allow the control of a position, the regulation of a volume or the regulation of a speed.

The following table explains the differences between the three control modes "Position", "Volume" and "Speed":

Control type Effect Brief description

Control of position damper position In position control, the

Flap position regulated, e.g. an input signal of 50% controls the valve proportionally to 50%.

Volume flow control When controlling the volume (water / air) flow, the damper is opened or closed until the deviation between setpoint and actual value falls below a threshold.

Regulation of the Velocity The control signal is generated by a device. The difference between the setpoint and the actual value is used to control the speed or the running time. In the case of cruise control as well, a volume flow is ultimately regulated. The term "speed control" is a historical one: special control devices provide output signals which are used as drive signals for the drives, in the volume control range these output signals are between 2 ... 1 0 V. The center in the range 2 ... 1 0V is 6V As soon as the setpoint agrees with the actual value, the drive is controlled with 6V and stands still The following points describe the behavior: 1. If the deviation between the setpoint and the actual value is more than 1% and is positive, then travel the drive with maximum speed OPEN 2. If the deviation between the setpoint and the actual value is more than 1 0% and negative, the drive will run CLOSED at maximum speed 3. The smaller the deviation between the setpoint and the actual value, the more the speed is shorter or the greater is the running time with which the drive moves to OPEN or CLOSE 4. If the setpoint and the actual value are off are regulated, ie does not exceed a threshold, then the speed = 0 resp. the runtime is infinite and the drive stops.

FIG. 26 schematically shows the transit time behavior as a function of a control voltage U6 or W1 of a drive.

Figure 27 shows schematically the relationship between the percentage difference signal and the drive signal of a drive. The different types of control can be configured in software in one embodiment, for example with a so-called PC tool. Figure 1 6 shows schematically in a block diagram 1 6.1 for various combination options of the functions described. The embodiment shown in Figure 1 6 with the closed contacts corresponds to a position control. If, for example, the Y input signal is an SR / SRS drive signal, this always results in a min. / Max. Setting independent of the control mode. If for some reason the Input Filter 2 is required, only the volume or speed control is possible. The control signal resulting from the respective control mode is fed to the motor of the drive. The control mode volume is only possible with an SR / SRS control signal, for other control signals this control mode is blocked. At the output of the control mode position is the input filter 1, which can be changed with MP commands. At the output of the control modes Volume and Speed is the Input Filter 2, which can not be changed.

Another MFT functionality of a drive, in particular an electric drive of a valve for regulating the flow of fluids in HVAC systems (HVAC valve), for example a damper drive of an HVAC system, relates to the braking of the drive before a stop position is reached. By reducing the speed to a nominal speed, the mechanism and in particular the gear before reaching the mechanical stop, so in particular the complete closing or opening an air damper, protected from damage and overloading.

Another MFT functionality of a drive, in particular an electrical drive of a valve for regulating the flow of fluids in HVAC systems (HVAC valve), for example a flap drive of an HVAC system, relates to the restart after an overload situation. An overload can be assumed if, for a few seconds, a target position does not coincide with the actual position if, for a few seconds, the actual speed is equal to or near zero, if the actual position is outside a rubber sealing area. Figure 28 shows schematically a so-called rubber function, which can also be referred to as a shut-off function. As soon as the actuating signal comes in an end region, which is provided in FIG. 28 with the reference numeral 28.1, the drive moves completely into the end position. The rubber function essentially corresponds to a limitation of the work area. While the limitation of the working range results in the filtering of electrical noise, the rubber function serves to overcome a possible resistance of a seal, in particular a rubber seal, of a flap. In one embodiment, the rubber function is constantly active, so that at setpoint values of, for example, <1%, ie, ZU, or> 99%, ie, UP, the actual value never reaches this setpoint.

If a drive detects one of these overload situations, then the drive can, for example, generate an MP message and place it on the MP bus, which can be evaluated by a control center. In the case of an overload situation, the torque of the drive can be maintained for a certain time before it is lowered. After lowering the torque can be tried at intervals again and again, whether normal operation has become possible again. The intervals can be chosen smaller first and later bigger and bigger.

The adjustment range of a drive, in particular an electric drive of a valve for regulating the flow of fluids in HVAC systems (HVAC valve), for example a flap drive of an HVAC system, can be determined by adaptation or by synchronization. During adaptation, both mechanical stops are approached without interruption. The driven area is taken over as the setting area and the running time and the setpoint range are automatically adapted to it. In the case of synchronization, a distinction is made between normal synchronization and concealed synchro- tion. During normal synchronization, the preferred mechanical stop, ie, for example, either 0% or 100%, is approached. The start of the position measurement is taken over at this point, without changing the setting range. The hidden synchronization relates to the case in which the drive during a Stromunter-

5 break is adjusted with the manual adjustment. Then, after restarting the drive, the actual position is no longer correct. With the hidden synchronization this error is corrected as soon as the preferred stop is reached during operation. The hidden synchronization thus does not trigger any movement of the drive and is activated each time the drive is restarted. Once an adaptation or synchronization has been performed, the hidden synchronization is disabled. To check the drive function, the drive may be configured to perform a test run, with the drive initially set to a minimum position, i. in the MIN position or 0% position, moves and then in the maximum position, i. in the MAX position or 1 00% position, moves. The functions adaption, synchronization or test run can be performed by means of an MP command

1 5 or be triggered by a provided on the drive button, for example, if necessary, an LED display is provided on the drive to display these functions. It can also be provided a status byte, which can be queried for example via an MP command MP_Get_State.

In a drive, in particular an electric drive of a valve for controlling the flow of fluids in HL systems (HL valve), for example a damper drive of an HVAC system, a nominal setting range can be programmed. The nominal setting range does not apply due to an adaptation by approaching the mechanical limit stops, but instead it defines a parameterized angle (for rotary drives) or a parameterized stroke (for linear drives). With a setpoint jump between Min = 0% 25 and Max = 1 00%, the nominal setting range is within a preset, set value Run through the runtime. In order to activate the nominal setting range for a drive, it is sufficient to perform a synchronization, ie to approach the preferred mechanical stop. If a nominal setting range is programmed, the drive behaves as shown schematically in FIG. The mechanically adapted setting range 1 7.2 can be set between the positions "CLOSE" and "OPEN". The nominal setting range 1 7.1 can be set between the positions Min = 0% and Max = 1 00%. The position "CLOSED" of the mechanically adapted setting range 1 7.2 coincides with the position "CLOSED" of the nominal setting range 1 7.1, the nominal setting range 1 7.1 being smaller than the mechanically adapted setting range 1 7.2. In the case of a drive, in particular an electric drive of a valve for regulating the flow of fluids in HVAC systems (HVAC valve), for example a flap drive of an HVAC system, an axstell range can be programmed instead of a nominal setting range. In this case, the mechanically adapted setting range 1 7.2 is constantly compared with the maximum range. If the mechanically adapted setting range 1 7.2 is greater than the maximum setting range, the message "increase setting range" is triggered, for example For a valve without a mechanical opening stop, the drive travels to the internal stop during adaptation.To account for this, a maximum range is programmed Valve overshoot takes place.

In a drive, in particular an electric drive of a valve for regulating the flow of fluids in HVAC systems (HVAC valve), for example a butterfly valve operating an HVAC system, a minimum, a mid and a maximum value can be set. The effectiveness of the control signals is limited to the range between Min value (0%) and Max value (100%). The mid value serves as an additional position for certain applications. In a plug-in drive, ie a drive of the example on a

5 damper shaft with attached damper is attached, the adjustment range refers to the adapted adjustment range. In the case of a VAV drive (VAV: variable volume flow), the value 100% corresponds, for example, to the nominal volume flow V _nom . For example, the priority of the min value is greater than the priority of the max value. If the Min value is parameterized greater than the Max value, the drive always moves to the Min value with a setpoint value in the case of the Ano-io controller. The min, mid and max values can be read and written via MP commands. As schematically illustrated in FIG. 1, an adapted setting range is read out with the MP command MP_Get_Relative and a Y signal (input signal), which is set between values 0% and 100%, is set to a minimum value (MP_Set_Relative) with the MP command ( 0%) and one

1 5 Max value (1 00%) of the drive set.

In a drive, in particular an electric drive of a valve for controlling the flow of fluids in HVAC systems (HVAC valve), for example, a damper actuator of an HVAC system, for VAV applications, the min-value setting and the Max-value setting for air flow limitation , In manual mode, i. without

20 a higher-level controller is connected to the drive can be approached by a forced control in addition to the min value and the max value, for example, in addition an intermediate position with a mid-value. For example, in position control, the end positions of a damper can be set via the min-value setting and the max-value setting such that e.g. always a minimum volume flow

25 or flow is present or that the volume flow or flow is a Ma does not exceed the maximum value. For constant volume operation, a constant volume can be set with Vmin.

In order to check the function of a drive, in particular an electric drive of a valve for controlling the flow of fluids in HVAC systems (HVAC valve), for example, a damper actuator of an HVAC system, for example, a test run can be performed, the drive, for example, first the Min position (0%) starts and then the maximum position (1 00%) anfährt. After that, the drive continues, for example, according to a control signal or moves to the mid position. During the test run, different values can be queried and checked. For example, with an MP command MP_Get_Relative the adapted setting range can be queried or the actual value can be displayed. Via a feedback signal, which is assigned in drives, for example, the marking U5, for example, the current actual position can be read. The MP command MP_Get_State can be used, for example, to read whether synchronization is active for the drive, whether the adaptation is active, whether the test run is active, whether the motor is at the adapted stop, if the piggyback is active, or if hidden synchronization is active is whether the engine stop is active, etc. In particular, it can be read whether the max position is reached.

In order to improve the performance of a drive, in particular an electrical drive of a valve for regulating the flow of fluids in HVAC systems (HVAC valve), for example a damper drive of an HVAC system, a so-called boost function may be provided. So that the drive has sufficient starting torque, a current limit is increased for a limited time and then lowered back to the nominal value. The boost function is activated especially when starting a drive. In order to protect the transmission of a drive, in particular an electric drive of a valve for controlling the flow of fluids in HVAC systems (HVAC valve), for example, a damper actuator of an HVAC system, it may be provided to approach the mechanical end stops at a reduced speed , In FIG. 20, for an adapted range of 90 ° and a set brake band of 0.5 °, the regions which are traversed at nominal speed or at a reduced speed are shown. The stop on the mechanical end stops thus takes place with reduced energy, which in particular the transmission of the drive is spared. In an embodiment variant, the reduced speed is also set shortly before reaching a setpoint value, in particular as soon as the difference between the setpoint value and the actual value is smaller than the set brake band. By reducing the speed before reaching the setpoint, the setpoint can be approached in particular more precise. In one embodiment, the nominal speed is 940 rpm, while the reduced speed is 470 rpm, ie half the nominal speed. However, the speeds may have any other values or ratios. The set brake band is stored in a memory of the drive and can be configured as desired.

In one embodiment, a braking ramp is provided, which is particularly advantageous in high-speed drives, especially in electrical drives of valves for the regulation of the flow of fluids in HVAC systems (HVAC valve), such as damper actuators of an HVAC system. To save the transmission, a reduced speed is not set until reaching a set brake band. The ramp speed is set according to an algorithm as a function of the difference between a setpoint and an actual value. For example, the speed can be proportional to the difference between the setpoint and be reduced to the actual value. For example, the speed is reduced the closer the end stop is reached. In the case of a rubber seal at an end stop position, the reduction of the speed can be canceled as soon as the area of the rubber seals of the end stop is reached. This ensures in particular a sufficient sealing effect of the rubber seal.

In one embodiment variant, a drive, in particular an electric drive of a valve for controlling the flow of fluids in HVAC systems (HVAC valve), for example a damper drive of an HVAC system, has the function of the sealing closure, which activates, for example, via an MP command can be. For example, with setpoints <1% (CLOSED) resp. > 99% (OPEN) the drive travels 1% resp. After reaching the setpoint value. 99% with a greatly reduced braking speed to the respective end stop on. Thus, despite mechanical tolerances or, for example, aging sealing lamellae, a sealing closure of a flap can be ensured. The area in which the sealing closure is to take place, that is to say the range of 1% in the example mentioned, is stored, for example, in a memory of the drive and can be correspondingly configured.

In one embodiment variant, a drive, in particular an electric drive of a valve for controlling the flow of fluids in HVAC systems (HVAC valve), for example a flap drive of an HVAC system, has the option of operating in a master / slave mode. Several such drives are mounted mechanically coupled, wherein the torque applied to a flap shaft is generated by the drives evenly. As shown schematically in FIG. 21, a master and the slaves connected thereto are specially connected, wherein the master receives a control signal at one input and a corresponding one at an output to the slaves Control signal transmits, in such a way that the torque generated by the arrangement with the master and the slaves is evenly distributed to the master and the slaves. In the application identical drives are used, which are set up to perceive either the function as a master or the function as a slave. The switchover is fully automatic during operation, for example, a piggyback identification is provided. In the case of an overload, which is pending, for example, for more than 1 s, the U5 signal, for example (see FIG. 21), is changed by a small value, for example. If the drive can continue, then it is concluded that slave drives are present and it is switched to piggyback mode. A drive which can be operated both as a master and as a slave is described in PCT / CH201 1/000038.

A drive, in particular an electric drive of a valve for controlling the flow of fluids in HVAC systems (HVAC valve), for example, a damper actuator of an HVAC system, in particular a plug-in drive, is referred to as a V-drive, if this has programmed a speed control and with a volume flow controller is used. The V-drive is designed for control with a control signal of 6 ± 4V, ie for the range 2V ... 1 0V, whereby the V-drive stands still at 6V. The speed control is possible via any control signals, eg via MP commands, via an SR control as described above, via a PWM control, etc. The basic setting for a V drive is, for example, that 0% and 2V and 1 00% and 1 0V correspond. At a setpoint of 0%, the drive rotates counterclockwise at maximum speed (Max_Speed). At a setpoint of 50%, the drive stops. At a setpoint of 1 00%, the drive turns clockwise with Max_Speed. With a stop-and-go function, with a V-drive in the case of volume flow control, the required flap position can become very slow be set until it is reached that the setpoint = actual value. In this case, oscillation of the V drive for setting a desired value can be avoided. FIG. 22 shows the dependence between the drive voltage and the transit time or between the drive voltage and the engine speed, respectively. the speed. From FIG. 22, for example, it can be seen from FIG. 5 that if the drive voltage is in the range of 5V ... 7V, then the running time is above 320 s or the motor speed below 280 rpm.

In one embodiment, a drive, in particular an electric drive of a valve for regulating the flow of fluids in HVAC systems (HVAC valve), for example, a damper drive of an HVAC system, a spring drive for a Fel o derrücklauf in the event of a power failure. This makes it possible, for example, to ensure that the flap controlled by the drive is guided in the event of a power failure in a defined position, for example, is guided or closed to a certain stop. The energy for the spring return is stored mechanically in a spring. The spring return takes place, for example, in a predetermined time, which is longer or shorter, depending on the drive or transmission. The drive is set up, for example, to store an adjustable return time. For unlocking the drive has a hand crank mechanism with which the drive can be held in one position. To detect the unlocking of the hand lock a special algorithm or a sensor is provided, for example, the difference of a Potentiometerposi- tion and an internal incremental encoder is determined. If the deviation is, for example, greater than 5 °, then it is concluded that a manual intervention takes place and a corresponding function call is made. The drive has in one embodiment, a feedback potentiometer, which is used to control the return speed. Without feedback potentiometer, a value is regulated to any value, ie the drive moves quickly or slowly. In a further embodiment variant, a drive, in particular an electric drive of a valve for regulating the flow of fluids in HVAC systems (HVAC valve), for example a damper drive of an HVAC system, comprises a so-called SuperCap. A SuperCap is an electrical energy store, with charge and discharge controlled by a microprocessor, for example. For example, to identify the aging of the SuperCap, the drive has an LED that signals the end-of-life of the SuperCap after a functional test of the SuperCap or after an aging period. For storing the electrical energy, a double-layer capacitor can be used. If the supply of the drive fails, there is sufficient energy in the SuperCap to reach a desired position at a definable speed, ie, for example, a value of 0% to 1 00%. This can be done with an adjustable delay so that there is no change in position in case of a short power interruption. As soon as the power supply is active again, the drive, for example with a delay of, for example, 3 s to wait for a stable power supply, moves into the position according to the current control signal. With a SuperCap a variety of security features can be covered. In an installation with multiple drives, the positions of the drives can be set according to a regime so that, for example, a ventilation system controlled by the drives is adjusted in the event of a power failure such that, for example, risks related to the propagation of fire and smoke are minimized.

In one embodiment variant, a drive, in particular an electric drive of a valve for regulating the flow of fluids in HVAC systems (HVAC valve), for example a damper drive of an HVAC system, is set up as a VAV drive (VAV: variable volume flow). A VAV drive differs from other drives by a volume flow sensor and a volume flow control loop. The relationship between the pressure difference dp and the volume flow is described by a root function. This is linearized, resulting in stabilization of the control loop and easier customization to different Original Equipment Manufacturer (OEM) transducers as well as orifice plates, crosses, etc. FIG. 23 schematically shows a VAV control loop, wherein a measurement signal associated with the pressure difference dp is processed and compared with a setpoint value to control a motor which moves a flap in a ventilation tube. In a VAV service mode, for example, 2 LEDs are provided for displaying the control states of the air. In the VAV service mode, it is displayed whether the air has been regulated or whether there is too much or too little air. The VAV service mode can be manually switched on and off, with a shutdown, for example, at the latest after 2 hours automatically. For example, in a register EEB_VAV_MODE_EXT different OEM behavior can be realized by setting bit values. For example, bit0 = 1 is for customer A, bit1 = 1 for customer B, bit2 = 1 for customer C.

In one embodiment variant, a water drive, in particular an electric drive of a valve for regulating the flow of fluids in HVAC systems (HVAC valve), for example a flap drive of an HVAC system, is set up to shut off valve curves via software control. The a values of a heat exchanger are entered and the optimum valve curve is calculated, with the associated setpoints being relayed to the actuators.

For the diagnosis of components and functions of an HVAC system, in particular for the diagnosis of a current operating state of a drive, in particular an electrical drive of a valve for regulating the flow of fluids in HVAC systems (HLK valve), for example, a damper actuator of an HVAC system, data storage and data interfaces are provided to store operating data at any time retrievable. Thus, for example, on a master device, ie a device which is configured and operates as a master, an MP bus (MP: Multi Point) several slave devices, ie devices which are configured as a slave and work to be connected. Operating data of the devices include in particular an MP status, a lifecycle byte, the number of operating hours, a power-down counter, messages of all types, software update and auto-upgrade information, a record of operating conditions and / or environmental conditions, etc. The data interfaces are set up, to allow access to stored data via appropriate commands.

On the MP bus commands are defined in a known manner, in particular to query data or control drives, in particular electrical drives a valve to control the flow of fluids in HVAC systems (HVAC valve), such as damper actuators of an HVAC system. Thus, the command MP_Get_Status allows access to the MP status as well as the reading of the current operating status of a device. In the case of a damper actuator, the current operating status includes, in particular, the following status flags and drive parameters: [1] Statusl: AC supply available, nominal actuator range active, positive function> 0, release active, disengaged key pressed; [2] Status2: Synchronization active, adaptation active, test run active, motor on adapted stop, piggyback active, hidden synchronization active, stop motor active; [3] Status3: MANUFACTURER login active (logged in with MANUFACTURER password), OEM login active (logged in with OEM password); [4] Status4: reserved for fire protection; [5] Status5: reserved for future status flags or drive parameters; [6] Status6: Target speed; [7] Status7: actual speed. Other stored data relate to a lifecycle status, which is used for quality assurance and in particular for product liability. For example, in drives such as in particular the so-called modularization drives or the drives known under the HALOMO product name, one or more bytes are provided in the Lifecycle Status Register in which test results are stored, such as results from a print test or PCB test, a final test or a final test, a parameterization in particular of default values, a field parameterization such as with a so-called PC tool, ie the functional test of print circuits of a drive from a final test, ie in particular the functional test of an entire drive, or even field parameters , eg of settings on the drive, which are made during installation or during operation. The MP command MP_Set_Lifecycle_Byte and MP_Get_Lifecycle_Byte are defined for saving data and accessing the Lifcycle Status Register.

Other stored data relate, for example, the number of operating hours, for example, between operating time and active time is distinguished. The operating time defines, for example, the time during which the drive was connected to a power supply. For example, the active time defines the time during which the motor of the drive was active, ie, either moving or overloading. From the relationship between active time and operating time, a utilization factor of the drive can be determined, eg utilization factor [%] = active time [h] / operating time [h] = transit time [h] / service life [h]. From this it can be read whether the drive is constantly in Be ^¬ drive or predominantly stands still. Thus, in particular oscillating drive can be detected by a high utilization rate. Further stored data concerns the switching off of the drive. Each switching off of the supply voltage or each switching on of the supply voltage is stored in a counter of the drive, the number of off or on circuits are stored. This information is for diagnostic purposes. If a drive is frequently switched off or switched on, it is possible, for example, to conclude that the power supply is unstable.

In one embodiment variant, a drive, in particular an electric drive of a valve for regulating the flow of fluids in HVAC systems (HVAC valve), for example a flap drive of an HVAC system, comprises a status display, in particular one or more LEDs, in case of detected malfunctions to signal these. Due to the signaled malfunction, for example, a service call of the service personnel is required. The signaling of malfunctions takes place, for example, according to a conservative approach, so that rather a message is displayed too little than that an unnecessary service is too much to perform. The status display can, for example, indicate one or more of the following malfunctions: utilization too high, setting range has been increased, overload has been detected, target position could not be reached, fault of the SuperCap. Further messages can be provided. The signaling of malfunctions can be classified, for example, malfunctions can be assigned to a malfunction or to a maintenance, whereby the signaling of the malfunction is deleted by appropriate operating handles. The signaling of a malfunction can be assigned to several classes at the same time, wherein several control handles can be provided for deleting the signaling. If the signaling of a malfunction is cleared without the cause of the error being corrected, it will reappear. In one embodiment, a drive, in particular an electric drive of a valve for controlling the flow of fluids in HVAC systems (HVAC valve), for example, a damper drive of an HVAC system, via software update or via auto upgrade options. An update or upgrade ensures that forward and backward compatibility is guaranteed. If, during a release change, the allocation of registers or of persistent storage cells changes, for example, an automatic adaptation to the data is provided, wherein a marking of the data is necessary, which shows whether the update has already taken place or not. In one embodiment variant, a drive, in particular an electric drive of a valve for regulating the flow of fluids in HVAC systems (HVAC valve), for example a flap drive of an HVAC system, has password protection. For example, performing MP commands may require you to enter a password. Several password levels can be provided. Unconditionally executable MP commands can be executed without a password. For example, MP commands with a reference to the OEM (original equipment manufacturer), eg an MP command for calibrating a sensor connected to the drive, require an OEM password for execution. For example, manufacturer-specific MP commands, for example an MP command for resetting a counter that relates to switching on or off, require a manufacturer password for execution. An MP command MP_Login may be provided to log in with, for example, the OEM password or the manufacturer password, with the execution of appropriate MP commands enabled. Changing the OEM password or the manufacturer password requires that the old password be specified or that a login be made with the old password.
