Method for configuring converters for sensors and converter

The present invention provides a method of operating a powder coating system, comprising at least one coating device, a coating compartment and a suction system in the coating compartment. In the method, a workpiece is passed through a coating compartment. The coating powder is discharged by the coating device to the workpiece and excess coating powder is sucked off from the coating compartment, wherein the powder mass flow of the coating powder discharged by the or each coating device is detected and the suction system is controlled in accordance with the powder mass flow. For this purpose the invention provides a powder coating system comprising a measuring means for detecting the powder mass flow of the coating powder discharged by the or any coating device, and an actuator means for setting the suction system in accordance with the powder mass flow.

Electrostatic powder coating system

The invention refers to a method of detecting workpieces in an electrostatic coating system, comprising at least one electrostatic coating device, which applies a high voltage to a high voltage electrode, in which the high voltage electrode generates a spray current including electrostatic charges for charging particles of a coating medium to be sprayed, an electrically conductive workpiece to be coated is moved past the coating device, the spray current of the high voltage electrode is determined and it is detected in accordance with the magnitude of the spray current whether the workpiece is in front of the coating device.

Method of detecting workpieces in an electrostatic coating system

The invention relates to a control system of a coating apparatus for a coating medium, such as powder or wet lacquer, comprising at least one coating device, in which a quantity measuring means for determining the amount of coating medium supplied to the coating device, a quantity control means for setting the quantity of the coating medium to be discharged by the coating device, and a digital control device for controlling the operation of the coating device are associated to the or any coating device, wherein the control device, the quantity measuring means and the quantity control means are connected to one another by a bus structure.

Control system of a coating apparatus

The invention refers to a method of controlling a coating device, which discharges a coating medium such as a powder or wet lacquer to a workpiece, in which in accordance with the shape of the workpiece the shape of the cloud of the coating medium discharged is automatically adjusted by changing at least one of the velocity, and the quantity, and the mass flow of the coating medium discharged or shaping air. The invention further refers to a coating installation capable of operating by this method.

Method of controlling an electrostatic coating device and an

A device and method of measuring and controlling the flow rate of a fluid determine analog process variables which are dependent on a volumetric flow of the fluid, and the values thus obtained are converted into digital values, the latter being corrected by an offset value which is dependent on a change of the operating parameters of analog components of the measuring system occurring in the course of operation of the system. To obtain the offset value, an analog process variable is determined during interruptions in operation, when the volumetric flow is zero, and converted into a digital value. This digital value is memorized and used as the offset value when operations are resumed. The digital corrected measured values are supplied to a digital signal processor and the flow rate control is carried out digitally. Preferably, at least one parameter memory is provided for the digital control.
