Zusammenfassung von EP 2175459 (A1): 
The present invention refers to a method (61) to operate a control device (13) for energising (97) at least one coil (33) of an permanently magnetisable chuck (15) to modify a magnetisation of the chuck (15), wherein the control device (13) comprises an electrical connection (17) having at least one conductor (C1-A,C1-B,C1-C,C1-D,C1-F) to connect power supply circuitry (25) of the control device (13) with the coil (33). In order to provide such a method (61) which is safe and protects the control device (13) and/or the chuck (15) from being damaged due to a faulty connection (17) between the control device (13) and the chuck (15) it is suggested that the method (61) further comprises verifying (63,65) electrical characteristics at the at least one conductor (C1-A,C1-B,C1-C,C1-D,C1-F) and/or electrical characteristics (i) of the power supply circuitry (25), wherein said verifying (63,65) is performed before said energising (97).
