According to a further aspect, the invention creates a door drive for driving a swing door, comprising a door drive control according to one of the previously explained embodiments.

According to a further aspect, the invention creates a revolving door, comprising a frame, a revolving leaf pivoted on the frame about a lateral vertical axis, and such a door drive.

So far, the problem has arisen that when manually operating doors for buildings and structures, in particular swing doors that are equipped with electric drives, when the door position “CLOSE” is reached, the door does not seal due to mechanical play in the drive system and/or the counter pressure of the door seals positioned in the door frame.

In a particularly preferred embodiment of the invention, a manual door movement in the “DOOR CLOSED” direction is detected with the aid of a position sensor. If the driven door leaf is shortly before the end position "DOOR CLOSED" - especially if a reversing limit of the motor-driven system is reached - the drive system switches on and gently guides the door - i.e. at a lower speed, for example - into the natural end position of the frame .

Particularly preferably, following this process, the door drive control is referenced, whereby taking into account the mechanical slip or mechanical play of the drive system is corrected.

1. a) Verhindern von Zugluft,
2. b) korrektes Einrasten eines Türschnappers in ein Schließblech an der Zarge,
3. c) Reduzierung des Kraftaufwandes bei manuellem Zudrücken der Tür,
4. d) Erhöhung der Positioniergenauigkeit des Antriebes durch Korrektur des System-Schlupfes.

With particularly preferred embodiments, one, several or all of the following advantages can be achieved:

1. a) preventing drafts,
2. b) correct engagement of a door catch in a striking plate on the frame,
3. c) Reduction of the effort required when manually closing the door,
4. d) Increasing the positioning accuracy of the drive by correcting the system slip.

In a particularly preferred embodiment of the invention, parallel operation of at least two operating modes “automatic door closer function” and automatic operation - be it fully automatic or pulse sequence operation - is possible.

Swing door drives are used to automatically open and then close swing doors. The main area of application for these drives today is in public, commercial and barrier-free areas. The drives usually have different operating modes such as: B. the automatic operation (automatic opening after impulse and automatic closing after the dwell time has elapsed) or the door closer function, which cannot be operated in parallel with each other, as these must be permanently set using toggle switches on the drive or program switches on the wall. With the embodiment of the invention shown here, it is possible to operate the operating modes in parallel at any time.

1. a) kein Parallelbetrieb mit dem Automatikbetrieb möglich und somit kein automatisches Schließen der Tür, wenn diese aufgrund der geringen Selbsthemmung des Systems z. B. aufgrund von Zugluft die Endlage „Tür Zu“ ein wenig verlassen hat oder die Tür manuell geöffnet wurde und
2. b) Probleme bei der Aufhaltezeit für die Türschließerfunktion.

The disadvantages of previous solutions are in particular:

1. a) No parallel operation with automatic operation possible and therefore no automatic closing of the door if, for example, due to the low self-locking of the system. B. the end position “door closed” has moved a little due to drafts or the door was opened manually and
2. b) Problems with the hold time for the door closer function.

The advantageous embodiment of the invention enables the independent parallel operation of the automatic operation and door closer function operating modes. Furthermore, separate and different hold times can be set for automatic operation and the door closer function.

• a) Tür schließt sich wieder automatisch, wenn diese aufgrund der geringen Selbsthemmung dieser Antriebssysteme die Endlage „Tür Zu“ ein wenig verlassen hat.
• b) Tür schließt wieder automatisch, wenn diese manuell geöffnet wurde.
• c) Parallelbetrieb der Betriebsarten Automatik-Betrieb und Türschließer-Funktion. Sinnvoll, wenn z. B. behinderte mit nicht behinderten Personen in einem Haushalt leben. Die behinderte Person nutzt den Automatikbetrieb und die nicht behinderte Person öffnet die Tür manuell. In beiden Fällen schließt die Tür automatisch nach der Aufhaltezeit.

The particularly preferred embodiment offers one, several or all of the following advantages

• a) The door closes automatically again when it has left the “door closed” end position a little due to the low self-locking of these drive systems.
• b) Door closes automatically again if it was opened manually.
• c) Parallel operation of the automatic operation and door closer function operating modes. Makes sense if e.g. B. disabled people live in a household with non-disabled people. The disabled person uses automatic operation and the able-bodied person opens the door manually. In both cases the door closes automatically after the stay-open time.

According to a further embodiment and/or a further aspect of the invention, separate hold times are created for automatic operation and the “automatic door closer function” and Push & Go operating modes.

Swing door drives are used to automatically open and then close swing doors. The main area of application for these drives today is in public, commercial and barrier-free areas. The drives usually have different operating modes such as: B. the automatic operation (automatic opening after impulse and automatic closing after the stay time has expired), the Push & Go function or the door closer function, which are always operated with the same hold times. In the solution proposed here according to an advantageous embodiment of the invention, there are several different dwell times for the operating modes.

With door drives currently available on the market, there is only one uniform hold-open time. The door is open for the same length of time in all operating modes with automatic closing, even though the drive opens the door, for example. B. could often close again more quickly after a Push&Go command or after a manual door opening. When Push&Go operation is deactivated and the door closer function is activated, a shorter dwell time also makes sense.

An advantageous embodiment of the invention enables different dwell times to be set depending on the operating mode.

1. a) Lange Aufhaltezeit im Automatikbetrieb, da die Türöffnung z. B. per Funkbefehl aus etwas größerer Entfernung zur Tür eingeleitet wird.
2. b) Kürzer Aufhaltezeit im Push&Go Betrieb, da der Öffnungsvorgang durch das Anstoßen der Tür ausgelöst wird und man sich bereits an der Tür befindet und ggf. sogar mit dem Erreichen der Türendlage Auf die Tür bereits durchschritten hat.
3. c) Kurze Aufhaltezeit bei der Türschließer-Funktion, da sich die Tür nach kurzer Zeit wieder automatisch schließen kann, wenn diese aufgrund der geringen Selbsthemmung dieser Antriebssysteme die Endlage „Tür Zu“ ein wenig verlassen hat.

Features and/or advantages of preferred embodiments of the invention are, for example: b.

1. a) Long dwell time in automatic mode, as the door opens e.g. B. is initiated by radio command from a slightly greater distance from the door.
2. b) Shorter dwell time in Push&Go mode, as the opening process is triggered by pushing the door and you are already at the door and may even have already passed through the door when the door reaches its end position.
3. c) Short hold time for the door closer function, as the door can close automatically again after a short time if it has left the “door closed” end position a little due to the low self-locking of these drive systems.

In 1 a building door 10 that can be driven automatically if desired is shown in the form of a swing door 12 with a door drive 14.

The building door 10 has a wing 18 designed here as a rotating wing 16 and a frame 20.

The rotating leaf 16 is pivotally pivoted about a lateral vertical axis 24 on the frame 20 by means of door hinges or door hinges 22. The wing 18 is, as is well known for room doors or other building doors, equipped with a door handle 26 for manually operating a door lock, not shown. By pressing the door handle 26, a door catch (not shown) can be pulled out of its closed position on a striking plate (not shown) of the frame 20 in order to be able to open the wing 18 manually.

For selective automatic operation, the door drive 14 is provided, which has a door drive housing 28 and a motor-driven door drive arm 30. Different types of mounting are possible. For example, the door drive housing 28 could be mounted on the wing 18, with the free end of the door drive arm 30 being connected in a stationary manner in the area of the frame 20. Shown as an example is a type of assembly where the door drive housing 28 is fixed in place in the area of the frame 20, and a free end of the door drive arm 30 is connected to the wing 18.

Different options for connecting the door drive arm 30 are also conceivable. In the example shown, a slide rail 32 is provided, on or in which a free end of the door drive arm 30 can slide when the door drive arm 30 moves. Another type of drive, not shown here, is a so-called articulated arm linkage, whereby the door drive arm 30 forms a first rod element which is connected in an articulated manner to a second rod element, which in turn is connected to its other end.

These aforementioned types of assembly are well known for door drives 14 for swing doors 12 and are not explained in more detail here.

The door drive 14 has an input device for entering the selected type of installation. For example, one of several possible types of installation can be selected via an operator interface 50 when setting up the door drive 14. Possible types of mounting are, for example, 1) mounting the door drive 14 on the door leaf or 2) mounting the door drive 14 on the frame 20 and a) connection using a slide rail 32 or b) connection using the articulated arm and i) mounting on the hinge side (the in 2 side facing downwards) or ii) mounting on the opposite hinge side (the one in 2 side facing upwards) as well as any combinations such as 1.ai, 1.a.ii, 1.bi, 1.b.ii, 2.ai, 2.a.ii, 2.bi, 2.b.ii.

According to a particularly preferred embodiment, information about the position of the pivot axis 24 relative to the output shaft of the drive unit of the door drive 14 can be entered.

2 shows the building door 10 in a horizontal section, with the wing 18 in its final closing position “DOOR CLOSED”. The building door 10 is completely closed. The wing 18 rests on door seals (not shown), which prevents drafts from passing through the building door 10. In this final closing position, the wing 18 is held by the door catch acting on the strike plate of the frame 20.

3 shows schematically the internal structure of an exemplary embodiment of the door drive 14.

The door drive 14 has an electric motor 34, which is coupled to the door drive arm 30 via a door drive gear 36 in such a way that a rotation of a motor shaft 38 of the electric motor 34 generates a movement of the door drive arm 30 and, conversely, a movement of the door drive arm 30 produces a rotation of the motor shaft 38 of the electric motor 34 results.

A position sensor 40 is connected to the motor shaft 38.

The door drive gear 36 is form-fitting, i.e. essentially slip-free or provided with little residual slip, so that a position of the wing 18 connected to the door drive arm 30 can be detected on the motor shaft 38 by the position sensor 40.

Particularly in the embodiment explained above with the entry of information about the type of installation, an exact function between the position sensor or position of the motor shaft 38 and the position and/or movement of the closing edge 54 can be achieved.

Furthermore, the door drive 14 has a door drive control 42 for controlling the operation of the door drive 14.

A radio receiver symbolized by an antenna 44 is connected to the door drive control 42, which can be a bidirectional radio transceiver, and signals from an in 1 illustrated mobile remote control 46, in particular radio remote control, can receive.

A stationary signal generator 48 (or a stationary remote control) can also be connected to the door drive control 42. The signal transmitter 48 can, as indicated, be connected to the door drive control 42 by wire or also via a radio link. The signal transmitter 48 can be actuated by a person, for example, using buttons to operate the door drive 14.

The door drive control 42 further has a user interface 50, for example with a keyboard or selector switches or slide switches, by means of which a user can make settings on the door drive control 42.

The door drive 14 also has lighting 52, which can also be used as an optical signal for a user.

The door drive control 42 is connected to the position sensor 40 in order to detect positions of the connected door leaf 18 as well as position changes.

In particular, the door drive control 42 is designed such that it can position and/or move The closing edge 54 is detected. In particular, the kinetic energy of the wing 18 can thus be recorded, and a control of a movement of the wing 18 in the opening movement and/or closing movement can take place depending on the kinetic energy of the wing 18. This allows you to limit the impact energy in every position of the leaf 18 and optimize the door movement. This is particularly possible by entering the type of installation, as stated above.

The door drive control 42 is connected to the electric motor 34 to control the electric motor for automatically driving the leaf 18.

The door drive control 42 is designed to detect the power requirement of the electric motor 34. For example, the power consumption, the speed and/or the voltage or current of the electric motor 34 is recorded in order to draw conclusions about the current force to be applied. For example, as mentioned above, the kinetic energy can also be recorded as a further variable via the rotation speed and position, on the basis of which automatic control takes place.

The speed of movement is regulated so that the opening and closing speed in high-speed operation is so fast, but the kinetic energy of the closing edge remains below a predetermined limit. Here, the path-dependent transmission ratio of the gearbox provided and clearly determined by the type of assembly entered is taken into account, so that the rotational speed of the motor shaft is not constant, but is controlled accordingly depending on the path.

The door drive control can, for example, be operated in an automatic mode in order to move the leaf 18 by motor between its closing end position and an opening position.

Such an automatic operation can be initiated, for example, by a pulse train operation. For this purpose, a person who, for example, wants the sash 18 to open automatically can either operate the mobile remote control 46 or operate the stationary signal transmitter 48. The door drive control 42 recognizes this as a desire to open the leaf 18 automatically or - if the door, as in 4 shown, is already open - close automatically.

The type and sequence of automatic operation can be selected and set via the operator interface 54. Furthermore, different lead times, hold-open times and/or other control times can be entered for different types of command input - push operation, opening command via a first stationary remote control, opening command via a second stationary remote control or opening command via mobile remote control. These options for setting automatic operation are explained in more detail below.

During a motor-driven movement of the leaf 18, the door drive control 42 monitors the power requirement of the electric motor 34 in automatic mode. If the force to be exerted by the electric motor increases above a threshold value, it can be concluded that the leaf 18 is moving against an obstacle or a person . The door drive 14 then stops the corresponding movement and reverses it in order to move the leaf 18 back at least a little. This corresponding switch-off function or reversing function works during an automatic closing movement until shortly before the in 2 closing position shown.

In one embodiment, a so-called reversing limit can be set via the operator interface 50, which in 5 is indicated. For example, the power cut-off or reversing function works over the entire closing path until the closing edge 54 of the sash 18 is still a predetermined adjustable distance 56 - the reversing limit - from its position in the final closing position. The distance is, for example, slightly less than 50 mm. In another embodiment, the position of the reversing limit is predetermined by the manufacturer. The reversing limit can, for example, be a fixed size, for example predetermined based on the door opening angle. For example, a reversing limit is specified at, for example, 2° door opening angle.

Given a correspondingly small distance 56, one can assume that an increase in the force when the distance 56 is exceeded is caused by the stop of the wing 18 on the frame 20 or on the door seals.

The distance 56 of the reversing limit should preferably be chosen such that no body parts or other objects can be trapped between the closing wing 18 and the frame 20.

In addition to the previously explained automatic mode, the door drive 14 is also set up so that the wing 18 connected to it can be operated manually.

In 6 is a schematic block representation of a possible exemplary embodiment of the door drive control 42 using function blocks. The corresponding devices indicated by the function blocks can be implemented, for example, by appropriate programming of a central processor unit of the door drive control 42.

The door drive control 42 has an automatic mode control 58 for controlling the door drive in automatic mode. The automatic mode control 58 can be activated, for example, by the remote control 46 or the signal transmitter 58, as indicated by an automatic mode control command 60. The automatic mode control 58 carries out the above-explained automatic mode of the door drive 14, which is also well known in door drives.

The door drive control 42 further has a manual operation detection device 62 for detecting a manual operation of the building door 10.

The manual operation detection device 62, for example, monitors the position sensor 40 and detects a manual operation when the position of the leaf changes, without the electric motor 34 having been correspondingly controlled by the door drive control 42.

If a manual operation is detected, a manual mode control 64, for example, is activated. Preferably, the door drive control 42 is in manual mode by default, except that an automatic mode is activated by an operator via signal generator 48 or remote control. After carrying out the automatic movement, the door drive control 42 then returns to the manual mode, in which the manual mode control 64 is active.

The manual mode control 64 de-energizes the electric motor 34 in such a way that the motor shaft 38 can be passively rotated without increased resistance due to the application of force on the door drive arm 30. This allows a user to open the wing 18 manually, for example up to the in 4 opening position shown. The user can also remove the wing 18 from the in 4 Manually close the opening position shown, as indicated by the arrow in 4 is indicated.

The manual mode control 64 has a closing movement detection device 68, which is connected to a position sensor 40 and detects the manual closing 66 of the wing 18 based on a movement of the position sensor 40.

Furthermore, the manual mode control 64 has a closing end area detection device 70 for detecting whether the wing 18 enters a closing end area 72 near the closing end position during manual closing. The closing end region 72 corresponds, for example, to the distance 56, which is set by the reversing limit.

The manual mode control 64 also has a closing device 74 for automatically closing the sash 18 into its final closing position.

The closing device 74 is connected to the closing end region detection device 70 and is designed in such a way that when it is detected that the wing 18 moves into the closing end region 72 during manual closing 66 or is not in the closing end position but within the closing end region when the manual mode is active 72, controls the electric motor 34 in such a way that it pulls the wing into the closing end position at a low movement speed, which is, for example, slower than a normal movement speed in the normal movement range outside the reversing limit.

The wing 18 is driven by the closing device 74 - similar to automatic mode - into its stop against the frame 20; then the electric motor 34 is switched off and the closing end position reached, defined by the stop, is stored as a new reference value for a target closing end position in the door drive control 42.

Due to this reference value, the closing end position and thus a point of the movement distance of the leaf 18 is always well known, even in manual mode, so that the door drive control can always reliably determine the door position based on the signals from the position sensor 40 using the reference value, even if the door drive gear 36 or the connections of the door drive arm 30 should still show slippage.

Thus, any play or slippage within the motor and the door drive gear 36, including the connection to the driven door element, can be corrected.

The closing device 74 always ensures safe and comfortable closing of the building door 10, even in manual operation.

In 7 a block diagram of the automatic mode control 58 is shown, which is designed to carry out different automatic and / or semi-automatic operating modes.

The door drive control 42 and in particular the automatic mode control 58 can be adjusted through the operator interface 50, in particular as part of a setup during commissioning, with different operating modes being adjustable. The operator interface 50 can be designed, for example, as a DIP switch, with operating modes and functions being able to be switched on or off by setting individual switches.

In particular, different control times t1.1, t1.2, t2.1 and t2.2 (possibly also other control times) can be set via the operator interface 50 and stored in a memory M. Different control times can be set for different operating modes.

In particular, different warning times t1.1 and t1.2 can be set. If the door leaf is to be driven from a rest position in the opening or closing direction, the door drive control 42 waits for the pre-set warning time t1.1 or t1.2. An optical and/or acoustic early warning signal can be emitted.

Furthermore, different hold times t2.1 and t2.2 can be set and different hold times can be assigned to different operating modes.

Automatic operating modes are in particular an automatic operation, which is represented by a function block A, which represents an automatic operation mode control - for example a program routine with corresponding sequence steps - and a pulse sequence operation, which is represented by a function block I, which is a pulse sequence -Operating mode control - e.g. a program routine with corresponding steps.

In automatic mode, the automatic mode control 58 controls the electric motor in response to a start signal in such a way that a complete opening is carried out and then the corresponding hold time t2.1 or t2.2 is waited until a complete closure occurs again.

The hold time t2.1 or t2.2 is selected depending on the selected operating mode and depending on the start signal. It is, for example, possible to select different dwell times t2.1 and t2.2 for different stationary signal generators 48, 48a and/or it is possible to select different dwell times t2.1 and t2.2 for an actuation via the stationary signal generator 48 on the one hand and an actuation on the other hand, select via the mobile remote control 46.

Accordingly, different advance warning times t1.2, t1.1 can also be controlled depending on the start signal.

In pulse sequence operation, control is carried out in such a way that every movement is initiated by a pulse. A movement can be stopped by a second impulse; the wing 18 remains in the corresponding position. If no impulse is given during the movement, the wing moves through the movement process to the next end position, where it stops until another impulse is received. From the closed position, a first pulse initiates an opening process until the wing 18 - unless it is previously stopped by another pulse - reaches its opening end position. A second pulse then initiates a closing process from the opening end position until the wing 18 - unless it is previously stopped by another pulse - reaches its closing end position.

The automatic operation and the pulse sequence operation are active in parallel and can be selected by each user by selecting a corresponding first or second channel K1 or K2 on the remote control 48, 48a, 46. A signal on the first channel K1 initiates an opening and closing cycle after automatic operation, a signal on the second channel K2 results in a pulse to activate pulse sequence operation.

Stop or advance warning times t1.1, t1.2, t2.1, t2.2 are selected by the control depending on which input E1, E2 the signal is input through. Accordingly, the different remote controls 48, 48a, 46 can be assigned different control times.

Another function is the so-called door closer function, which is represented by a function block T, which represents a door closer mode control - for example a program routine with corresponding steps.

To enable automatic opening, one of the lock's catches is deactivated. This can be done by a striking plate that gives way under pressure or by holding the catch in a retracted position. The door 10 is then held in the closed position essentially solely by the door drive 14.

If the door closer function T is active, the door drive control monitors the position of the door to determine a door position outside the closed position. If such an open position is detected, a preset hold time t2.1 or t2.2 for the door closer function is waited for, then the door operator operates Friction control automatically closes the door to the final closing position.

The door closer function T can, for example, automatically close a door 10 that has been opened by wind pressure or by manual operation.

Another operating mode is the semi-automatic operating mode or push function, which is represented by a function block P, which represents a semi-automatic or push function mode control - for example a program routine with corresponding sequence steps.

If the push function P is active, then a manual operation of the door 10 is detected as shown above. However, this does not lead to the activation of the manual mode control 64, which is rather deactivated when the push function is active, but is recognized as a start signal for an automatic movement. If you manually push the leaf 18 slightly in the opening direction from its closed position, this is recognized as a start signal for an opening movement, and the door drive control carries out a complete opening. Depending on whether the door closer function T is activated or not, a complete cycle - opening - hold time - closing is carried out when the door closer function T is active, or the door moves - when the door closer function is inactive - into the open position and remains there until it goes through an impulse or another manual push is driven back into the closing direction.

• 1.) Automatikbetrieb (Tür schließt automatisch nach Ablauf der Aufhaltezeit für den Automatikbetrieb)
• 2.) Impulsfolgebetrieb mit der Möglichkeit „Dauerauf“ und „Lüftungs- bzw. Zwischenstellungen“ zu realisieren.

According to an exemplary embodiment of the door drive control 42, the following operating modes are possible and adjustable:

• 1.) Automatic operation (door closes automatically after the hold time for automatic operation has expired)
• 2.) Pulse sequence operation with the option of implementing “continuous on” and “ventilation or intermediate positions”.
• 3.) Semi-automatic (also called push operation) with “door closing function” (also called AutoClose) with separate hold time for the semi-automatic and the door closing function.
• 4.) Semi-automatic without “door closing function” with the option of realizing “continuous open”.
• 5.) Manual door operation with “door closing function” with the hold time of the semi-automatic
• 6.) Manual door operation without “door closing function” with the option of realizing “permanent open” and “ventilation position” by hand.

• 1,2,3
• 1,2,4
• 1,2,5
• 1,2,6.

According to this embodiment, the following possible combinations of the different operating modes are possible:

• 1,2,3
• 1,2,4
• 1,2,5
• 1,2,6.

Preferably, a first retention time t2.1 and a second retention time t2.2 are programmed such that the first retention time t2.1 is longer than the second retention time t2.2. A longer dwell time t2.1 is assigned to the mobile remote control and/or automatic mode A, for example. A shorter dwell time t2.2 is assigned, for example, to the stationary remote control 48 located near the door 10, for example directly on the frame, and/or to the push operation P. The door closer function T can also be coupled with the short hold time t2.2.

This makes it possible to assign shorter opening times to operations in which it can be assumed that the operator has already passed the door or will pass in a very short time than to operations in which a later passage through the door is to be expected.

Overall, this can contribute to shorter door opening times without compromising operator comfort. This can contribute to significant energy savings, particularly when the door 10 separates more heated or more air-conditioned rooms from less heated or unheated or less strongly or not at all air-conditioned areas.

Some interesting new functions of a new concept for a door drive 14 or its door drive control 42 are briefly explained again below.

The first new function is a closing function.

If you close the door manually, the door opens a little again and then closes.

This removes the play from the door drive. In the last few millimeters or centimeters, the door is pulled into the lock by the motor, even in manual operation.

This results in better locking; the door is driven against the seals.

Another idea is to combine multiple functions. With previous door drives, different functions can be set, but they are mutually exclusive or have to be selected and adjusted accordingly.

• - Eine Automatikfunktion, wo die Tür einmal einen Öffnungsvorgang, dann eine Öffnungshaltezeit dann wieder ein Schließvorgang durchführt (ein Öffnungsimpuls reicht aus);
• - Einen Impulsfolgebetrieb wo die Tür auf einen ersten Impuls geöffnet wird und dann offenbleibt bis ein neuer Impuls erfolgt.

The new door drive now provides:

• - An automatic function where the door performs an opening process, then an opening hold time and then a closing process again (one opening pulse is sufficient);
• - A pulse sequence operation where the door is opened on a first impulse and then remains open until a new impulse occurs.

The third function would be the so-called push function; here someone goes through the door manually. The door is held open briefly and then closes automatically again. In one embodiment of the door drive 14, it acts like a normal door closer; one difference is the keep-open time, which can be set.

The open time leads to another idea.

You can set different opening times. Depending on whether the operation takes place from close up or further away.

For example, a longer hold-open time can be set in automatic mode than in manual mode or in so-called push mode.

In push mode, the door is briefly pushed; The drive recognizes this and then carries out automatic operation. The manual opening and the subsequent door closer function can also be set with a correspondingly short hold-open time.

In automatic mode, for example, a button is pressed that is a little further away from the door; Here it makes sense to hold the door open longer than in the other company.

The different functions - hold function or automatic function can be done by controlling different channels.

On a remote control, for example, there are two different buttons for automatic operation and hold-open operation.

For stationary actuation devices with pushbuttons, etc., a double pushbutton can be provided with two different functions. Here the corresponding impulse is sent on a corresponding channel so that the door carries out the different functions depending on the actuation.
