摘要:
A fuse base connection terminal apparatus comprises a base (1). At least one conductive copper bar (2) is arranged on the base (1). A connection bolt (3) and a connection nut (4) used for selectively connecting to an external cable are arranged in the base. A groove (12) used for mounting the connection nut (4) is arranged under the conductive copper bar (2) on the base. The connection nut (4) is mounted in the groove (12). The connection bolt (3) passes, under the groove (12), through the connection nut (4) and the conductive copper bar (2) sequentially. A top end of the connection bolt (3) extends above the conductive copper bar (2). The apparatus has a simple structure, is convenient and practical, and can provide two different types of cable connection manners, thereby meeting different requirements, saving materials, and reducing costs.

The invention concerns a system for operating an electric machine and a method for protecting an operation control unit in such a system. The system comprises an operation control unit (20), an alternating current cable (16) connecting the machine (30) with the operation control unit and an electric short-circuiting arrangement (26). This arrangement is connected to terminals of the operation control unit facing the cable and short circuits these terminals based on a detected overvoltage.
摘要:
A method in an industrial safety system for controlling a process or equipment, which industrial safety system includes components with safety devices. The safety system enables signals to be generated as a result of an event or alarm, where the method includes creating an automated link between the event or alarm and an effect or an action to be taken upon receipt of the event or alarm signal due to the event. The method includes configuring one or more links between the event and the input, thus forming a cause and effect matrix, and also generating a control code using the cause and effect matrix for subsequent download of the control code to at least one process controller whereby a control signal is subsequently generated by at least one safety controller to initiate the action or effect.
摘要:
A wireless vibration sensor suitable for connection to a distributed industrial control system arranged with a wireless network for communication of process data or control information. The wireless vibration sensor includes at least one sensor, a wireless radio transmitter, and a base part for mounting it firmly on equipment or a structure. The wireless sensor is arranged with a battery and a power storage device. A method for powering up the wireless sensor during active cycles is also described.

A live handle switch in the form of a hand operated safety switch for an industrial robot or a machine is described. The live handle comprises a safety certified switch for operating a robot or other machine safely while under manual control. The live handle switch may be comprised in a portable robot controller of the TPU Teach Pendant unit type. Such a TPU may comprise control means for moving a robot in three or more degrees of freedom. In other aspects of the invention a system comprising a robot and a control unit and the live handle switch are described.
摘要:
Sensor failure in an oil and gas production system is monitored and detected by checking the consistency of the measurements of the sensor in question using a computer-based process model with the measurements of the other sensors in the system. The present invention also generates a back-up value for a failing sensor with the process model by identifying the value that is most consistent with the measurements of the other sensors in the system.
摘要:
An apparatus for cleaning one or more parts of an automated painting or coating equipment comprising a source of gas under pressure, a source of a cleaning agent, a mixing means (3) for adding the cleaning agent to the said gas, and supplying it to the automated painting or coating equipment. The mixing means (3) is adapted to release the cleaning agent into the gas under pressure such that the amount of said cleaning agent released varies with time.
摘要:
An apparatus for spray pattern control in an automated painting or coating apparatus comprising a supply of compressed gas (1), a valve means (11a,11b) controlling the gas supply to an applicator (5), and a conduit (1) transporting said gas from the supply to the applicator (5). A pressure sensing means (13) is arranged to measure the pressure of the gas delivered to the applicator (5), and a control loop (12) uses said valve means (11a,11b) to regulate the pressurized gas flow to control gas pressure at the applicator (5) based on the measured gas pressure.
