Method and electronic power supply device for supplying power to a low-voltage load protected by a protective device

Abstract: The invention relates to an electronic power supply device, particularly a switched-mode power supply, for supplying power to a low-voltage load protected by a protective device, and to a method therefor. The invention also relates to a device for protecting a low-voltage load against an excess current and to an auxiliary power supply device for use with such a protection device. The conceptual core of the invention can be seen in providing measures which ensure that after a fault has been detected, for example a short circuit at the output, a current is supplied for a short period, for example 15 ms, which is of such a magnitude that a protective device can be reliably and quickly tripped. The period for this is selected in such a manner that electronic components, connected loads and feedlines are not damaged and destroyed.

Safety switching unit for controlling a safety device into a safe state

Abstract: The invention relates to a safety switching unit, with which a safety device, preferably an electric drive, can be controlled into a safe state. The safety switching unit (900) comprises a microprocessor or microcontroller (822) that, for example, can control an electric drive to be protected both when actuating an emergency switch, protective door switch and/or two-hand switch as well as during a faulty operation of the safety switching unit or of the electric drive into a safe state. To this end, the microprocessor (822) is preferably designed so that it can determine from at least one analog signal to be measured whether a predetermined parameter, preferably the amplitude of the analog signal, lies outside a predetermined operating range. In addition, the microprocessor (822) can be a component of a safety device (810), which is configured for the multichannel controlling of a safety electric drive. This enables the safety switching unit (900) to be able to respond to a number of safety functions that are independent of one another in order to control an electric drive into a safe state. In addition, the risk of a wiring error in a compact safety switching unit is considerably reduced compared to known measures.

Circuit arrangement for protected data transmission, particularly in ring-shaped bus systems

Abstract: A circuit arrangement allows data, which are necessary for building up fault-tolerant structures, to be transmitted on standard ring-shaped bus systems. Its implementation requires a monitoring unit and input and output units which transmit or receive data for control. The circuit arrangement handles the task of detecting any faults which can become a danger for the process within a machine or plant. Due to its internal configuration, the circuit arrangement identifies any fault even before the detection of the fault and initiates a protected switch-off. In this arrangement, it is of no importance whether it is the external control unit or the bus system used which is responsible for the fault.
