摘要： A method is disclosed for operating an electric switch having at least one movable switch contact, movable by a movable armature of an electromagnetic actuator to switch the switch on and off, a spring device arranged between the movable switch contact and the armature and, in order to move the armature from a starting position to an armature end position, a magnetic flux being generated in an exciter winding of the actuator by an exciter current being fed into the exciter winding. According to an embodiment and taking into account a position data set which specifies the respective armature position as a function of magnetomotive values and flux values, an armature position—called the contact strike armature position below—is determined at which the switch contacts meet each other during the closing operation, before the armature reaches the armature end position.

摘要： A method for controlling a current flowing through a consumer comprises the following steps, which are periodically traversed: determining a dither current based on a dither signal and a definite point in time, wherein the dither signal is determined by a frequency, an amplitude and a signal form and actuating a flow control valve to produce the sum of a target current and the determined dither current by the consumer. Furthermore, the method comprises determining an indication to the current flowing through the consumer; compensating the indication by the factor of the dither current; and providing the indication, wherein the determination of the dither current and the determination of the indication are synchronized with each other in a predetermined way.

摘要： A method of solenoid valve control includes measuring voltage across the solenoid valve and current through the solenoid valve, and using the results to aid in controlling the solenoid valve. For instance, one or both of the measured values may be used to determine when actual engagement of the solenoid valve occurs. An initial lower voltage and lower current can be used, and then as conditions change, the changes in condition can be accounted for by increasing voltage and current to maintain the desired response time of the solenoid valve. By measuring and controlling voltage and current less of a margin can be used, both in setting voltage/current levels and in selecting the time over which a pull voltage/current is utilized. This reduces the wasted energy in the system, as well as reducing the temperature rise in the solenoid valve.
