Abstract:
Proposed is a magnetic valve with manual override, through the actuating element of which a magnetic core that serves as a valve element or that is connected to a valve element can be shifted from an off position into an operating position without excitation of a magnetic coil system assigned to it. To detect the position of the magnetic core that is held in the operating position by the manual override there is provided a coil current monitoring device that monitors the rise of the coil current after the magnetic coil system has been switched on, which device has a detection device for detection of the absence of a drop in current as formed by movement of the magnetic core after being switched on and a signaling device for electrical signaling of a position of the magnetic core that is held in the operating position by the manual override if said drop in current is absent.
