Monitoring method and monitoring device for an electrostatic coating plant

摘要

An electrostatic coating plant coats components with a coating agent that is electrically charged by high voltage device. A first operating variable of a high voltage device may be determined and compared to a limit value. A safety measure may be initiated if the comparison between the first operating variable and the limit value indicates a disturbance in the electrostatic coating plant. The limit value may be flexibly adjusted depending on the operation mode.

1. A monitoring method for an electrostatic coating installation, which coats components with a coating agent, which is charged electrically by a high voltage device, the monitoring method comprising:
ascertaining a first operating variable of the high voltage device; comparing the first operating variable with a limit value; specifying a target value for the first operating variable or a second electrical operating variable of the high voltage device; controlling the first or second operating variable in accordance with the specified target value; fixing the limit value as a function of the specified target value; and initiating a safety measure if the comparison between the first operating variable and the limit value indicates a malfunction of the electrostatic coating installation, the safety measure including at least one of switching off the high voltage device and adjusting the operating variable; wherein the limit value is set flexibly as a function of operation.
