MANUAL RESERVATION BLOCK Russian patent published in 2006 - IPC G05B7/02 

FIELD: engineering of control devices, in which smooth switching from automatic monitoring of process being controlled to manual and vice versa (from manual to automatic) is provided due to generation of control signal by comparison of output signal of adjuster with manual control signal being set, possible utilization for controlling objects of various purposes.

SUBSTANCE: new in invention is that in known system third and fourth switches are mounted, third and fourth adders and second integration amplifier, input of which is connected to output of fourth switch, while output is connected to third input of third switch, to second input of second adder, to second input of third adder and to second input of fourth adder, first input of third switch is connected to output of adjuster, to first input of third adder and to first input of fourth adder, while output of third switch is connected to input of executive mechanism, output of third adder is connected to third input of first switch, output of fourth adder is connected to first input of fourth switch, while second input of fourth switch is connected to output of second adder.

EFFECT: increased reliability of control.
