Beschreibung
Zusammenfassung:	A method for operating a coating device for coating a metal strip. The corresponding coating device has an electromagnetic strip-stabilizing device having a plurality of electromagnetic actuators or coils for applying forces to the metal strip. In order to ensure that the strip-stabilizing device is operated only within the operating limits thereof, the magnitudes of the set currents for the actuators or the coils are compared with a specified current threshold value or the forces applied to the metal strip by the actuators are compared with a specified force threshold value and the correction roller is moved into such an adjustment position that the magnitudes of the set currents are below the current threshold value or the magnitudes of the forces are below the force threshold value.
