摘要:
A protective device (1) for electrical networks and for electrical user devices connected to an electrical network comprises at least a first circuit breaker (2) which can be inserted between an electricity supply (4) and a load (3), switchable between a normal closed condition and an open condition to selectively interrupt the power supply to the load (3); automatic reconnection means (5), acting on the first circuit breaker (2) to automatically switch the first circuit breaker (2) to the closed condition. The device (1) also comprises a second circuit breaker (6) operatively connected between the first circuit breaker (2) and the load (3), switchable between a closed position in which the first circuit breaker (2) and the load (3) are electrically connected and an open position in which the first circuit breaker (2) and the load (3) are electrically disconnected; a monitoring control unit (7) operatively connected to the first circuit breaker (2) and to the second circuit breaker (6) at least for switching the second circuit breaker (6) between the closed position and the open position.

摘要:
The invention relates to a module arrangement of safety switching devices, comprising at least one input module (18) for processing the signals of a transmitting safety device (20) and for generating output signals; and at least two output modules (19; 19.1, 19.2) for controlling an actuator (21) according to the output signals. The input module (18) and the output modules (19) are arranged in a series, forming a module series, and the input module (18) is allocated to an output module (19). The inventive module arrangement is characterized in that the input module (18) is allocated to the first, second or both output modules (19) according to the position of the input module (18) in the module series.

The invention relates to a modular safety switchgear system for switching actuators (21) on and safely off, comprising at least one input module (18) for safely evaluating a safety device (20) and for generating an output signal, and at least one output module (19) for safely actuating the actuator (21) depending on the output signal of the input module (18), whereby at least the input module can be operated in different operating modes. The inventive system is further characterized in that it is provided with a control module (16) for individually adjusting the operating mode of every input and output module (18, 19) and with a display means (30) for safely displaying the adjusted operating mode of the input module (18) and/or the output module (19).
摘要:
The use of foot actuated switches or push-button switches, which are individually and respectively associated with each device, in order to control electromechanical devices or groups of devices is known per se. A plurality of push-button switches or foot actuated switches are required to control a plurality of devices or devices. This can lead to disruptions in operating theaters as a result of the various connections. According to the invention, connectors (20) or similar connecting devices are provided for the foot actuated switches or push-button switches, enabling the switching devices to be connected to each other. Allocating devices are provided in order to allocate specific control functions in relation to the devices or groups of devices to the control signals. Information transfer devices transfer control signals from the switching devices or foot actuated devices to the devices or groups of devices.
摘要:
Die Erfindung betrifft eine Steuereinrichtung für einen über ein Bussystem (2) vernetzbaren Motorstarter (1), bei welchem Temperatur und Leistungsmessdaten des Elektromotors (M) fortlaufend überwacht und mit Grenzwerten verglichen werden und Daten aus dem Bussystem (2) ausgewertet werden und in Abhängigkeit von den ausgewerteten Daten und den überwachten Messwerten Steuerbefehle zur Ansteuerung des Motorstarters (1) erzeugt werden, wobei über Schaltelemente (11) unterschiedliche Konfigurationen und Parameter vorgegeben und gemeinsam mit den Daten aus dem Bussystem (2) und den Messwerten zur Erzeugung der Steuerbefehle ausgewertet werden, so dass als Direkt- oder Wendestarter ausgebildete Motorstarter (1) ansteuerbar sind und Elektromotoren (M) unterschiedlicher Leistungsaufnahme überwachbar sind.
