An electrical coupling state is monitored between an inductive load and a circuit configuration. The latter has a first and a second coupling point for coupling to the inductive load. A first voltage value is determined between the first and second coupling points. The first voltage value is tested for the occurrence of a characteristic voltage pulse, which can be triggered by reduction of a magnetic flux in the inductive load by way of a steep-edged change in the amount of current flow through the inductive load. An error is identified in the coupling state if the characteristic voltage pulse does not occur within a predefinable time period. The absence of an error in the coupling state is also identified if the voltage pulse does occur.
A method of verifying an electrical coupling state between an inductive load and a circuit configuration, wherein the circuit configuration is coupled to the inductive load via first and second coupling points, and the method comprises:
A device for monitoring an electrical coupling state between an inductive load and a circuit configuration having first and second coupling points for coupling to the inductive load, comprising:
A monitoring device configured to:
