Abstract
A method for controlling an electromagnetic drive of a switching device by means of a program, wherein a processor configured by the program executes the following steps: measuring a control voltage applied at an input of the switching device; activating the electromagnetic drive on the basis of the measured control voltage; and setting a rated voltage range on the basis of the measured control voltage.

A method for controlling an electromagnetic drive of a switching device by means of a program, wherein a processor configured by the program executes the following steps:
- measuring a control voltage applied at an input of the switching device;
- activating the electromagnetic drive on the basis of the measured control voltage;
- and
- setting a rated voltage range on the basis of the measured control voltage,
- wherein setting the rated voltage range on the basis of the measured control voltage comprises calculating a lower switch-on voltage threshold and an upper switch-off voltage threshold on the basis of the measured control voltage.
