  • Patent number: 10295984
    Abstract: A safety-related control device for controlling an actuator with a first processing device that is configured to provide a safety function for the generation and/or processing of a signal for a safety-related control of the actuator, and a second processing device that is configured to provide an operating and/or additional function for the generation, processing, diagnostics, reproduction and/or transmission of further signals associated with the operation of the control device and/or of the actuator, and wherein the second processing device is furthermore configured to provide a test function for monitoring the functionality of the safety function.

  • Patent number: 8567442
    Abstract: In a soft start device for pneumatic systems comprising a primary inlet where compressed air can be supplied at primary pressure, wherein the primary inlet is, via a valve circuit, connected to at least one secondary outlet which can be coupled to a load and where compressed air can be discharged at secondary pressure, the secondary pressure being lower than or equal to the primary pressure, wherein a main valve is installed between the primary inlet and the secondary outlet, a restrictor device being installed in the bypass, wherein the main valve and the restrictor device together with further directional valves of the valve circuit are interconnected such and the valve circuit can be switched into a standard switching position for venting such that the secondary outlet is vented, the valves of the valve circuit are interconnected such that several further switching positions for venting are possible.

  • Publication number: 20110277843
    Abstract: In a soft start device for pneumatic systems comprising a primary inlet (P1) where compressed air can be supplied at primary pressure, wherein the primary inlet (P1) is, via a valve circuit, connected to at least one secondary outlet (P2) which can be coupled to a load and where compressed air can be discharged at secondary pressure, the secondary pressure being lower than or equal to the primary pressure, wherein a main valve of the type 2/2 nc (normally closed) which can be bypassed by means of a bypass (17) is installed between the primary inlet (P1) and the secondary outlet (P2), a restrictor device (13) being installed in the bypass (17), wherein the main valve (WV5) and the restrictor device (13) together with further directional valves (WV1, WV3, WV4, WV5, WV6) of the valve circuit are interconnected such and the valve circuit can be switched into a standard switching position for venting such that the secondary outlet (P2) is vented, the valves (WV1, WV3, WV4, WV5, WV6) of the valve circuit are interc

  • Patent number: 6769250
    Abstract: A fluid control system for security relevant control and a fluid control actuator, a local control means for a fluid control system, a software module for a local control means of a fluid control system and a method for the operation of a fluid control system. The fluid control actuator (10) is controlled by control instrumentality means (30) of a local control means (50). A sensor (16, 17, 27, 41 and 42) transfers information concerning operational states of the fluid control system to the local control means (50). For this purpose there is a provision such that the local control means (50) determines from such information whether there is a security relevant situation and if necessary performs a predetermined function. The security relevant functions are integrated in the fluid control system so that same is able to be employed as prefabricated unit.
