Abstract

See full text

An electromagnetic valve has a magnetic coil and a movable element coupled to a valve element. The magnetic coil, when excited, conveys the movable element in one direction to move the valve element from its initial position into its active position. A control circuit for the electromagnetic valve has a current source for optionally supplying current to the magnetic coil and a measuring device for measuring a voltage level of the magnetic coil and/or a current level through the magnetic coil. A monitoring unit which is connected to the measuring device establishes a switching state of the electromagnetic valve corresponding to the position of its valve element based on the intended current supply state of the current source and the current and/or voltage characteristic measured by the measuring device and, if appropriate, determines a fault state of the current supply and/or the electromagnetic valve.
