Accordingly, depressing of the start button 41 turns off NOR gate 57 which turns on". NOR gate 58 to hold NOR gate 57 of and which turns of NOR gate 61 and turns on NOR gate 62 to drive the product control valve to full open position. Fluidic indicator 43 connected by line 82 to the output port of NOR gate 62 is actuated to indicate the valve is in open position.

Since the output port 59d of the NOR gate 59 is connected to the control port 61c of the NOR gate 61, it turns the gate 61 on,” thereby delivering a pressure signal through line 80 to the control relay 63 to again apply a working pressure in the closed line 64 to activate the actuator 49 to move the valve toward closed position. Since the sensor 95 no longer senses the intermediate position, it removes the pressure signal from the line 97 to turn on NOR gate 60 and deactivate the fluidic indicator 44.

Should the start button 41 be depressed, it will turn off gate 57 which will not affect gate 58 since a signal is being received at control port 586 by virtue of the slow feed probe being covered. While gate 62 will turn on, it will not cause the actuator to move since gate 61 will still be on since gate 58 is off.
