To set the current time, press the control button 2 until the current time in high-speed has almost been reached.

The hours are counted up to 24, i.e. until the daily overflow, with all other digits remaining unchanged. Then the days of the week are counted further (if available). For example, to be able to program the minutes or hours after reaching the desired day of the week, the control button 2 must be released and pressed again until the desired time display is reached.

Description

Die Erfindung betrifft eine Bedienungseinheit für eine Schaltuhr mit Bedienungselementen für die Einstellung der aktuellen Uhrzeit, der Wochentage und der Ein- und Ausschaltzeiten sowie mit Mitteln für deren Programmierung und mit einer Anzeigeeinheit für die Darstellung dieser Werte.The invention relates to an operating unit for a time switch with operating elements for setting the current time, the days of the week and the on and off times as well as means for programming them and with a display unit for displaying these values.

Aus der Firmendruckschrift "Rex Zeitschalter", Ausgabe 1985/86, Nachdruck: September 1985 der W.E.G.-Legrand GmbH, Schlüssel-Nr. Dr.Nr. 11.01/0286, insbesondere Seiten 3, 5 und 7, sind Schaltuhren mit getrennten Bedienungstasten für die Uhrzeiteinstellung, den gewünschten Schaltzustand, die Schaltzeiten und für Permanentschaltungen bekannt. Permanentschaltungen werden dabei mit einem Drei-Stellungs-Schalter vorgenommen. Dabei ist in einer mittleren Stellung das Schaltprogramm wirksam, während in den beiden äußeren Stellungen ein Ausgansrelais der Schaltuhr permanent ein- oder ausgeschaltet wird. Die Permanentschaltung ist nur aus der Stellung dieses Drei-Stellungs-Schalters und nicht aus der Anzeigeeinheit ersichtlich.From the company brochure "Rex Zeitschalter", edition 1985/86, reprint: September 1985 by W.E.G.-Legrand GmbH, key no. Dr.No. 11.01 / 0286, in particular pages 3, 5 and 7, time switches with separate control buttons for setting the time, the desired switching state, the switching times and for permanent switching are known. Permanent circuits are made with a three-position switch. The switching program is effective in a middle position, while in the two outer positions an output relay of the time switch is permanently switched on or off. The permanent switching is only visible from the position of this three-position switch and not from the display unit.

Schaltuhren können in integrierter Technik sehr kostengünstig und raumsparend aufgebaut werden. Jedes zusätzliche Bedienungselement bedingt jedoch einen in der Relation hohen Aufwand und Raumbedarf. Aufgabe der Erfindung ist es daher, eine Schaltuhr so auszuführen, daß man auch bei der Realisierung mehrerer Schaltzeitpunkte mit möglichst wenig Bedienelementen bei einfacher Bedienbarkeit auskommt.Integrated timers can be built very cost-effectively and space-saving. However, each additional control element requires a relatively large amount of effort and space. The object of the invention is therefore to design a time switch in such a way that even with the realization of a plurality of switching times, as few controls as possible and easy to operate.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen sind in den abhängigen Ansprüchen angegeben.This object is achieved by the features of claim 1. Advantageous refinements are specified in the dependent claims.

Mit der beschriebenen Schaltuhr können also mit nur zwei Bedienelementen alle Funktionen gesteuert werden. Dabei werden mit dem ersten Bedienelement alle zeitabhängigen Bedienschritte gesteuert, nämlich:

  • - Einstellen der aktuellen Uhrzeit,
  • - Programmieren von Schaltzeiten,
  • - Löschen von programmierten Schaltzeiten,
  • - Beenden der Dauerschaltung.
With the described timer, all functions can be controlled with just two controls. The first control element controls all time-dependent operating steps, namely:
  • - setting the current time,
  • - programming switching times,
  • - deletion of programmed switching times,
  • - End the permanent switching.

Mit dem zweiten Bedienelement werden die Programmierschritte aufgerufen:

  • - Auslesen der SchaltZeitpunkte. (ggfs. zur Verstellung mit dem ersten Bedienelement 2)
  • - Programmieren der Permanentschaltung.
The programming steps are called up with the second control element:
  • - Reading out the switching times. (if necessary for adjustment with the first control element 2)
  • - Programming the permanent circuit.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Figur näher erläutert.An embodiment of the invention is explained below with reference to the figure.

Wie die Figur zeigt, weist die Schaltuhr eine Anzeigeeinheit 1 und zwei Bedientasten 2, 3 als Bedienelemente auf. Die Schaltuhr kann in Nullstellung zurückgesetzt werden, wenn die beiden Bedientasten 2 und 3 gleichzeitig getippt werden. Damit schaltet der Ausgang ab, alle Schaltzeitenspeicher werden gelöscht und die Uhrzeit beginnt mit der Sekunde "Null" zu laufen.As the figure shows, the time switch has a display unit 1 and two control buttons 2, 3 as control elements. The time switch can be reset to zero if the two control buttons 2 and 3 are pressed simultaneously. The output switches off, all switching time memories are deleted and the time starts to run with the second "zero".

Zum Einstellen der aktuellen Uhrzeit wird die Bedientaste 2 gedrückt. Wenn diese nur kurz angetippt wird, verändert sich die Uhrzeit um + 1 Minute. Wird die Bedientaste 2 länger gedrückt, so wird, gesteuert durch einen internen Taktgeber, die Zeitanzeige sowie ggf. die Wochentagsanzeige in der normalen zeitlichen Reihenfolge durchlaufen, wobei die Uhrzeiteinstellung z.B. in einem Schnelllauf in 10 Minuten-Sprüngen erfolgen kann. Zum Einstellen der aktuellen Uhrzeit wird dann die Bedientaste 2 solange gedrückt, bis die aktuelle Uhrzeit im Schnelllauf fast erreicht ist. Anschließend wird die Bedientaste 2 so oft angetippt, bis die aktuelle Uhrzeit exakt erreicht ist. Dieses Einstellverfahren dauert allerdings verhältnismäßig lang, wenn auch Wochentage mit eingestellt werden müssen.Control button 2 is pressed to set the current time. If this is only touched briefly, the time changes by + 1 minute. If the control button 2 is pressed longer, the time display and possibly the weekday display are run in the normal chronological order, controlled by an internal clock, whereby the time setting e.g. can be done in a quick run in 10 minute jumps. To set the current time, press the control button 2 until the current time in high-speed has almost been reached. Then the control button 2 is pressed repeatedly until the current time has been reached exactly. However, this setting procedure takes a relatively long time, even if days of the week must also be set.

In einer alternativen Ausführungsform, die sich insbesondere für Schaltuhren mit Wochenprogramm eignet, wird die Einer-Stelle der Minutenanzeige hochgezählt bis zum Überlauf auf die Zehnerstelle der Minutenanzeige. Dann wird die Zehnerstelle der Minutenanzeige bis zum Überlauf auf die Einer-Stelle der Stundenanzeige hochgezählt, wobei die Einer-Stelle der Minutenanzeige unverändert bleibt. Die Stunden werden bis 24, also bis zum Tagesüberlauf hochgezählt, wobei wiederum alle anderen Stellen unverändert bleiben. Anschließend werden dann (falls vorhanden) die Wochentage weitergezählt. Um zum Beispiel nach Erreichen des gewünschten Wochentages auch die Minuten bzw. Stunden programmieren zu können, muß die Bedientaste 2 wieder losgelassen und erneut bis zum Erreichen der gewünschten Zeitanzeige gedrückt werden. Damit ist es möglich, mit nur einer Taste in relativ kurzer Zeit Zeitpunkte während einer gesamten Woche einzustellen, wobei während der Einstellung die jeweiligen Anzeigen von Minuten, Stunden und Wochentagen optisch ablesbar bleiben.In an alternative embodiment, which is particularly suitable for time switches with a weekly program, the 1-digit position of the minute display is incremented until it overflows to the 10-digit position of the minute display. Then the tens digit of the minute display is counted up to the one digit of the hour display until the overflow, whereby the one digit of the minute display remains unchanged. The hours are counted up to 24, i.e. until the daily overflow, with all other digits remaining unchanged. Then the days of the week are counted further (if available). For example, to be able to program the minutes or hours after reaching the desired day of the week, the control button 2 must be released and pressed again until the desired time display is reached. This makes it possible to set points in time for a whole week in a relatively short time with just one button, with the respective displays of minutes, hours and days of the week remaining optically readable during the setting.

Die Anzeige der aktuellen Uhrzeit kann stets dadurch gekennzeichnet werden, daß ein Doppelpunkt in der Anzeige blinkt.The display of the current time can always be identified by the fact that a colon flashes in the display.

Zum Programmieren von Schaltzeiten wird die zweite Bedientaste 3 gedrückt. Dabei erscheint in der Anzeige zunächst ein Symbol für das Einschalten und - wenn die Bedientaste 3 nochmals gedrückt wird - ein Symbol für das Ausschalten. Mit der ersten Bedientaste 2 kann dann der gewünschte Schaltzeitpunkt eingestellt werden. Die Einstellung kann nach einem der beiden oben beschriebenen Verfahren erfolgen. Dabei kann die Zeitanzeige auch jeweils in Schritten des minimalen Schaltabstands springen.The second control button 3 is pressed to program switching times. At the same time, a symbol for switching on appears on the display and - if the control button 3 is pressed again - a symbol for switching off. The first switching button 2 can then be used to set the desired switching time. The setting can be made using one of the two methods described above. The time display can also jump in steps of the minimum switching distance.

Durch weiteres Drücken der zweiten Bedientaste 3 können nun ggfs. mehrere Ein- und Ausschaltzeitpunkte mit der Bedientaste 2 programmiert werden. Falls die Schaltuhr ein Wochenprogramm aufweist, kann je Wochentag eine begrenzte Anzahl von Schaltzeitpunkten vorgegeben werden, die durch mehrfaches Antippen der Bedientaste 3 nacheinander anzuwählen sind. Nach dem Durchlaufen der Schaltzeitpunkte je Wochentag springt die Anzeige auf den nächstfolgenden Wochentag. Nach Durchlaufen aller Wochentage können auch Tagesblöcke, z.B. Montag bis Freitag und Samstag, Sonntag vorgegeben werden. Damit ist es möglich, für das Wochenende und den Rest der Woche unterschiedliche Schaltprogramme vorzugeben, ohne daß die Schaltzeiten für alle Tage einzeln programmiert werden müssen.By pressing the second control button 3 again, several switch-on and switch-off times can now be programmed with the control button 2. If the time switch has a weekly program, a limited number of switching times can be specified for each day of the week, which can be selected in succession by repeatedly pressing the control button 3. After running through the switching times for each weekday, the display jumps to the next weekday. After running through all days of the week, daily blocks, e.g. Monday to Friday and Saturday, Sunday can be specified. This makes it possible to specify different switching programs for the weekend and the rest of the week without having to program the switching times for each day individually.

Wenn mit der Bedientaste 3 durch mehrfaches Antippen alle vorgesehenen Schaltzeitpunkte angewählt sind, so erscheint in der Anzeige ein Kennzeichen für das Ende der Programmierung. Wird dann die Bedientaste 3 nocheinmal getippt, so erscheint in der Anzeige wieder die aktuelle Uhrzeit. Der Programmiervorgang wird automatisch auch dann beendet, wenn die Bedientasten 2 und 3 während einer gewissen Zeitspanne nicht mehr betätigt werden. Auch in diesem Fall wird dann die aktuelle Uhrzeit angezeigt.If all intended switching times have been selected by pressing the control button 3 several times, an indicator appears for the end of the programming. If the control button 3 is then pressed again, the current time appears again in the display. The programming process is automatically ended even if control buttons 2 and 3 are no longer pressed for a certain period of time. The current time is then also displayed in this case.

Die eingegebenen Schaltzeitpunkte können durch wiederholtes Antippen der Bedientasten 3 in der Anzeigeeinheit wieder angezeigt werden. Dabei kann ein Schaltzeitpunkt auch gelöscht werden, wenn die Bedientaste 2 gedrückt wird, während dieser Zeitschaltpunkt in der Anzeige 1 erscheint. Anschließend kann in der beschriebenen Weise ein Schaltzeitpunkt neu programmiert werden.The switching times entered can be displayed again by repeatedly pressing the control buttons 3 in the display unit. A switching time can also be deleted if the control button 2 is pressed while this time switching point appears in display 1. A switching time can then be reprogrammed in the manner described.

Nach dem Programmieren der Schaltuhr steht ihr Ausgang ggfs. nicht in der durch das Programm bestimmten Ein- oder Ausstellung. Der programmgemäße Schaltzustand kann in einer Ausführungsform dadurch erreicht werden, daß mit der ersten Bedientaste 2 die Uhrzeit um 24 Stunden oder - im Falle eines Wochenprogrammes - die Uhr um eine volle Woche weitergestellt wird. In einer alternativen Ausführungsform kann die Schaltuhr aber auch so ausgeführt sein, daß automatisch mit jeder Veränderung einer Einstellung an der Schaltuhr oder nach einem Netzspannungsausfall das Schaltglied in die richtige Stellung gebracht wird, indem diese durch den Uhrenschaltkreis intern ermittelt wird.After programming the time switch, its output may not be in the display or exhibition determined by the program. In one embodiment, the switching status according to the program can be achieved by using the first control button 2 to advance the time by 24 hours or - in the case of a weekly program - the clock by a full week. In an alternative embodiment, the time switch can also be designed such that the switching element is automatically brought into the correct position with each change of a setting on the time switch or after a mains voltage failure, by this being determined internally by the clock circuit.

Die Schaltuhr kann unabhängig vom Schaltprogramm und ohne dieses zu ändern in einen permanenten Aus- oder Einschaltzustand gebracht werden. Ein permanenter Ein-Zustand wird erreicht, wenn die Bedientaste 3 länger als eine vorgegebene Zeit, z.B. zwei Sekunden, gedrückt wird. In der Anzeige erscheint dann anstelle der aktuellen Uhrzeit ein Kennzeichen für den permanenten Ein-Zustand.The time switch can be set to a permanent switch-off or switch-on state independently of the switching program and without changing it. A permanent on state is reached if the control button 3 is longer than a predetermined time, e.g. two seconds. An indicator for the permanent on state then appears in the display instead of the current time.

Zur Einstellung eines permanenten Aus-Zustands wird die Bedientaste 3 ebenfalls länger als zwei Sekunden gedrückt. Anschließend wird die Bedientaste 3 nochmals kurz angetippt. Der Ausgang der Schaltuhr bleibt dann permanent im Aus-Zustand, der auch in der Anzeige erscheint. Durch wiederholtes Tippen der Bedientaste 3 wechselt der Schaltzustand.To set a permanent off state, the control button 3 is also pressed for longer than two seconds. Then the control button 3 is briefly tapped again. The time switch output then remains permanently in the off state, which also appears in the display. The switching state changes by repeatedly pressing the control button 3.

Die Permanentschaltung kann dadurch aufgehoben werden, daß die Bedientaste 2 kurz angetippt wird. In der Anzeige erscheint dann wieder die aktuelle Uhrzeit. Die Schaltuhr wird mit Erreichen des nächsten Schaltzeitpunkts oder durch eine oben erläuterte Methode auf den programmgerechten Schaltzustand umgeschaltet.The permanent circuit can be canceled by briefly pressing the control button 2. The current time will then appear in the display again. The time switch is switched to the program-correct switching state when the next switching time is reached or by a method explained above.

Das Ausführungsbeispiel nach der Figur enthält noch eine zusätzliche Bedientaste 4. Mit dieser kann die aktuelle Uhrzeit um plus oder minus eine Stunde verstellt werden (beispielsweise beim ersten Antippen plus eine Stunde, beim zweiten Antippen minus eine Stunde usw.) Dies vereinfacht die Umstellung von Sommer- auf Winterzeit und umgekehrt.The embodiment according to the figure also contains an additional control button 4. With this, the current time can be adjusted by plus or minus one hour (for example, plus one hour when tapped for the first time, minus one hour when tapped for the second time, etc.). This simplifies the changeover from summer - for winter time and vice versa.

Eine solche zusätzliche Bedientaste für die Umschaltung von Sommer- auf Winterzeit ist aus der US-PS-4 385 841 in Form eines Umschalters im Zusammenhang mit einer digital programmierbaren Schaltuhr, die jedoch anders aufgebaut ist als die erfindungsgemäße, an sich bekannt.Such an additional control button for switching from summer to winter time is known per se from US Pat. No. 4,385,841 in the form of a switch in connection with a digitally programmable time switch which, however, is constructed differently than the one according to the invention.
