Abstract:
A method to detect a fault in a CPU of an industrial controller during on-line safety control of real world objects. An application program is complied into assembler instructions. A test application is complied into assembler instructions where the assembler instructions is a subset of the total number of assembler instructions available for the CPU. The application program is downloaded and the test application to a central unit of an industrial controller. The test application is repeatedly executed in the industrial controller. A result from the test application is repeatedly compared with the pre-defined result in the test module. A fault detected in the CPU as the result from the test application does not equal the pre-defined result stored in the test module and the unexpected result of the test application is due to the execution of an assembler instruction of the test application. The execution of the application program is aborted wherein the application program is prohibited from executing the assembler instruction which otherwise would cause the application program to fail.
Abstract:
Painting system for painting large objects comprising a paint booth with surrounding walls and a robot installation comprising a plurality of painting robots, each painting robot comprising a stationary base, a stand carried by the base rotatably arranged around a first axis, a first arm carried by the stand rotatably arranged around a second axis, a second arm carried by the first arm rotatably arranged around a third axis and a forth, a fifth and a sixth arm part carried by the second arm for orienting an attached painting tool.
Abstract:
A dosing device for a program controlled spray painting apparatus adapted for dosing electrically conductive fluid materials to a spray gun/applicator. The spray gun may be charged at a high voltage for electrostatically charged atomizing of electrically conductive fluid materials. A coating system includes the dosing device, which is moved by an actuator between a connecting member for a paint filling line or a cleaning fluid supply line, and a spray gun. A method and a computer program for carrying out the method.

Abstract:
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.
Abstract:
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.
Abstract:
A method, controller and control system for controlling a robot that is used in concert with at least one other robot to perform an operation on one or more work objects. Each robot controller checks whether a common reference value is not acceptable, and if so, provides a signal for the robot to wait before proceeding to the next task. Each robot controller also checks whether the target object is in the correct position or not; and also checks whether or not another robot has stopped. If either another robot has stopped and/or if the work object is not in the right position, the robot waits.
Abstract:
An apparatus for cleaning one or more parts of an automated painting or coating equipment including a source of gas under pressure, a source of a cleaning agent, a mixer for adding the cleaning agent to the gas, and supplying the cleaning agent to the automated painting or coating equipment. The mixer is adapted to release the cleaning agent into the gas under pressure such that the amount of the cleaning agent released varies with time.

Abstract:
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.
