FIELD: electronics.SUBSTANCE: system has multiple units of solenoid valves made as a manifold, where each unit of electromagnetic valves is controled by control signals, herewith multiple units of solenoid valves are divided into multiple groups, wherein the system additionally includes a control unit for direct control of the electromagnetic valves within the multiple units of electromagnetic valves in each of the multiple groups regardless of the control signals, and if the control signals are fed to inputs of the units of solenoid valves the control unit switches over the units of electromagnetic valves between the serviceable state able to control these units of solenoid valves and the non-serviceable state, when actuation of the units of solenoid valves is impossible.EFFECT: technical result is improved safety.13 cl, 7 dwg |
