Abstract: The present invention relates to a system and a method of preventing a contactor from being abnormally opened through a real-time detection of an operation, in which a contactor coil control unit, which applies an operation signal to a contactor coil (relay coil) that opens or connects contact points of a contactor (Relay), during a travelling of a vehicle applies an abnormal signal to the contactor coil by an external reason or a failure, the abnormal signal is detected in real time, so that it is possible to prevent the contact point of the contactor from being unintentionally opened by the abnormal signal, and particularly, it is possible to prevent an operating vehicle from being suddenly stopped by determining whether the vehicle actually travels based on a maintenance time of the abnormal signal and whether the abnormal signal is applied due to an actual failure of the contactor coil control unit.

Abstract: The invention relates to an Output Signal Switching Device (OSSD) having at least one pair of electric output terminals, the pair of electric output terminals comprises a first output terminal and a second output terminal. The OSSD further comprises first voltage reducing means providing a first voltage which is lower in magnitude than a supply voltage, second voltage reducing means providing a second voltage which is lower in magnitude than the first voltage, wherein the second voltage is applied to the first output terminal and the first voltage is applied to the second output terminal, and wherein switching means are provided which are adapted to separate the second voltage from the first output terminal and/or the first voltage from the second output terminal, if the magnitude of the voltage at the second output terminal is equal to or higher than the magnitude of the supply voltage and/or if the magnitude of the voltage at the first output terminal is equal to or higher than the magnitude of the first voltage.

Abstract: The invention relates to a household appliance (7) having at least one mechanical relay (1) and a switch detection device (8) for detecting a switch of at least one relay (1). The switch detection device (8) has at least one measuring device (16, 18, 19) for measuring an electric coil current (I) which flows through the relay (1) when the relay (1) is switched and at least one analysis device (10) for detecting the switch of the at least one relay (1) on the basis of the measured coil current (I). A method is used to operate a household appliance (7) which has at least one mechanical relay (1). According to the method, an electric coil current (I) which flows through the relay when the relay (1) is switched is measured, and a switch of the relay (1) and/or a delay time of the relay (1) is detected using the measured coil current (I). The invention can be advantageously used on cooking devices, in particular ovens, in particular for switching heating elements.

Abstract: Sicherheitsschaltungsanordnung (10) zum fehlersicheren Abschalten einer elektrisch angetriebenen Anlage (16), mit einem Sicherheitsschaltgerät (14), das ein Sicherheitsschaltrelais (48) mit einer definierten Ansteuerleistung aufweist und dazu ausgebildet ist, einen Stromversorgungspfad (52) zu der Anlage fehlersicher zu schließen oder zu trennen, und mit einem Meldegerät (12), das einen Betätiger (26) und einen Signalgenerator (30) aufweist, und über eine erste Leitung (20) mit dem Sicherheitsschaltgerät (14) verbunden ist. Der Betätiger (26) ist zwischen einem ersten definierten Zustand und einem zweiten definierten Zustand wechselbar und der Signalgenerator (30) ist dazu ausgebildet, auf der ersten Leitung (20) ein erstes Taktsignal (24) nur dann zu erzeugen, wenn der Betätiger (26) im ersten definierten Zustand ist. Ferner ist das Sicherheitsschaltgerät (14) dazu ausgebildet, dem ersten Taktsignal (24) elektrische Leistung größer oder gleich der Ansteuerleistung des Sicherheitsschaltrelais (48) zu entnehmen und den Gleichstrom zum Ansteuern des Sicherheitsschaltrelais (48) umzusetzen.

Abstract: A relay welding detector (72) is adapted for detecting welding fault of a relay (71). The relay (71) has a first electrical contact (711) coupled to a neutral terminal (N) of an alternating current (AC) power source (6) through a first power line (91), and a second electrical contact (712) coupled to a load (8) through a second power line (92). The relay welding detector (72) includes a signal generator (721) generating a test signal, a current transformer (722) wound with a portion of one of the power lines (91, 92) and generating an induced signal based on the test signal, and a determining unit (723) determining, based on the induced signal, whether the electrical contacts (711, 712) of the relay (71) are welded to each other.
