Zur Fehleranalyse und Überwachung der Funktion können bei Notleuchten beispielsweise von dem Betriebsgerät der Notleuchte ermittelte Störungen oder Ergebnisse eines Selbsttests mittels einer optischen Statusanzeige dem Anwender angezeigt werden, wobei die Farbe und/oder das Blinkmuster von an der Leuchte angebrachten Leuchtdioden (LED) Auskunft über die Störung bzw. das Testergebnis gibt.For error analysis and monitoring of the function can be displayed in emergency lights, for example, from the operating device of the emergency light detected disturbances or results of a self-test by means of an optical status display to the user, the color and / or flashing pattern of attached to the light emitting diodes (LED) information about the Disturbance or the test result gives.
Eine Abfrage/Auswertung von Statusinformationen ist oft auch schon bei der Entwicklung und Erprobung eines Betriebsgeräts hilfreich. Hierfür können von dem Betriebsgerät bzw. der Steuervorrichtung des Betriebsgeräts Informationen beispielsweise über den Betriebszustand, in den das Betriebsgerät gerade eintritt, erfasst und ausgegeben werden, um das Verhalten unter bestimmten Bedingungen zu testen.A query / evaluation of status information is often helpful even in the development and testing of a control gear. For this purpose, information about the operating state in which the operating device is currently entering can be detected and output by the operating device or the control device of the operating device in order to test the behavior under certain conditions.
Die Ausgabe der Statusinformationen erfolgt an speziellen dafür vorgesehenen Ausgängen der Steuervorrichtung, was die Anzahl der nötigen Anschlüsse erhöht. Eine Erhöhung ist jedoch nicht immer möglich oder führt zu höheren Kosten insbesondere bei der Verwendung von Mikrocontrollern als Steuervorrichtungen, welche nur eine begrenzte Anzahl von Ein- und Ausgängen haben. In einem solchen Fall müsste dann ein Mikrokontroller mit einer größeren Anzahl von Pins gewählt werden. Da es nur bestimmte Anzahlen von Pins gibt, kann dies zu ungenutzten Pins führen und damit unnötigen Kosten.The status information is output at dedicated outputs of the controller, increasing the number of ports required. However, an increase is not always possible or leads to higher costs, in particular when using microcontrollers as control devices, which have only a limited number of inputs and outputs. In such a case, a microcontroller would then have to be chosen with a larger number of pins. Since there are only certain numbers of Pins, this can lead to unused pins and thus unnecessary costs.

Aufgabe ist es insbesondere, ein Betriebsgerät zum Betreiben von Leuchtmitteln bereitzustellen, das kostengünstig ist und eine einfache Ausgabe von Informationen über Betriebszustände erlaubt.The invention is an object of the invention to provide a control gear that reduces the problems described.

Es ist auch möglich, dass bestimmten zeitlichen Pulsmustern bestimmte Betriebszustände zugeordnet sind.It is also possible that certain operating states are assigned to specific time pulse patterns.

Die Filtereinrichtung kann ein Hochpassfilter zum Filtern und Ausgeben des Statussignals und/oder ein Tiefpassfilter zum Filtern und Ausgeben des Steuersignals bzw. der Spannung/des Stroms enthalten, wobei das Statussignal eine höhere Frequenz als das Steuersignal bzw. die Spannung/der Strom aufweist.The filter device may include a high-pass filter for filtering and outputting the status signal and / or a low-pass filter for filtering and outputting the control signal or the voltage / current, wherein the status signal has a higher frequency than the control signal or the voltage / the current.
Das Statussignal kann von der Steuervorrichtung erzeugt und ausgegeben werden, sobald die Steuervorrichtung bzw. das Betriebsgerät mit Energie versorgt wird oder erst auf eine Anforderung hin. Hierzu weist die Steuervorrichtung einen Anschluss zum Empfangen eines Betriebszustand-Anforderungssignals auf und ist dazu ausgelegt, das Statussignal auszugeben, wenn das Betriebszustand-Anforderungssignal empfangen wurde.The status signal can be generated and output by the control device as soon as the control device or the operating device is supplied with energy or only upon request. For this purpose, the control device has a connection for receiving an operating state request signal and is designed to output the status signal when the operating state request signal has been received.
