Abstract
An auxiliary manual control device for cells of a pneumatic system comprises an intermediary casing connecting each cell to a baseplate on which the said casing is normally secured. The casing is provided with piping for directly connecting the orifices of permanent pressure supply and input signals, and an OR gate with two inputs, whose output is connected to the output orifice of the baseplate, one of the inputs of the gate being directly connected to the output orifice of the cell, whereas the other input of the gate is connected by a monostable manual operated pneumatic reverser either to the exhaust, which represents its rest position, or to the pipe of permanent pressure supply.
