Control unit for controlling e.g. load lifting magnet utilized in crane for transporting ferromagnetic material to attract goods, has input unit enabling change in output variable, where transition between values is continuously carried-out

摘要

#CMT# #/CMT# The unit has an input unit (301) for a manual operation, and an actuator (302) for outputting an output variable e.g. magnetization voltage or magnetization current (304), of a magnetic plate (303). The output variable assumes two values that are different from each other. The input unit enables a change in the output variable from one of the values to the other value by a single operation or a single rotary translational activity of the input unit, where the transition between the values is carried-out in continuous and/or stepless manner or by skipping. #CMT# : #/CMT# The input unit is selected from a group consisting of a joystick or a rotary potentiometer or a rotary switch or a touch screen or a touch panel or a one-handed operation device. Independent claims are also included for the following: (1) a magnetic plate system (2) a method for controlling a magnetic plate. #CMT#USE : #/CMT# Control unit for controlling a magnetic plate e.g. load lifting magnet and lifting solenoid, utilized in a crane for transportation of a ferromagnetic material to attract goods. #CMT#ADVANTAGE : #/CMT# The input unit enables the change in the output variable from one value to another value by the single operation or single rotary translational activity of the input unit such that the transition between the values is carried-out in continuous and/or stepless manner or by skipping, thus enabling a very fine adjustment and an exact change of an operating condition of the magnetic plate, and hence allowing easy and quick control of the magnetic plate during transportation. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic block diagram of a control unit for a magnetic plate. 301 : Input unit 302 : Actuator 303 : Magnetic plate 304 : Magnetization current.
