Abstract
The invention refers to a system for the technical safety check of solenoid valves, where during an operational switch of the solenoid valve, the induction current of the actuating magnet of the valve is recorded over time and stored as test function I=I(t). From the test function the control function I'=dI/dt is digitally calculated and after digital logarithmation also stored. Both functions may be displayed and evaluated simultaneously on the screen, which assures a better and more exact evaluation of the functional condition of the concerning solenoid valve, including any existing defects.
