Control unit for the pneumatic control of a cylinder, in particular an active bobbin creel of a textile processing machine or a cabling machine, comprising - a compressed air inlet for connecting a compressed air supply, - a working air outlet connectable to the at least unilaterally acting cylinder for operating the cylinder, - a valve unit arranged between the compressed air inlet and the working air outlet, and - an operating element for opening the valve unit to trigger a lifting movement of the connectable cylinder, - wherein the valve unit has a slide which can be slid from a closed to an open position of the valve unit by actuating the operating element inside the control unit, - wherein the control unit is designed in such a way that a self-holding valve function is achieved in which the lifting movement of the cylinder can be fully carried out upon only a single and/or brief actuation of the operating element, and - wherein the control unit can be connected to an end-position sensor of the cylinder such that the valve unit is closed when the end-position sensor is activated, - wherein the control unit has a sensor air inlet for connecting the end position sensor, wherein the valve unit is closed when there is a pressure increase and/or when a threshold pressure value of a sensor pressure at the sensor air inlet is exceeded, characterized in that a magnet is arranged on the slide such that the slide is held in the open position of the valve unit by the holding force of the magnet in the open position, and the sensor air inlet is arranged such that a pressure applied thereto counteracts the holding force of the magnet, wherein to this end the sensor air inlet is connected to a closed valve chamber arranged between the housing of the control unit and the magnet. - a compressed air inlet for connecting a compressed air supply, - a working air outlet connectable to the at least unilaterally acting cylinder for operating the cylinder, - a valve unit arranged between the compressed air inlet and the working air outlet, and - an operating element for opening the valve unit to trigger a lifting movement of the connectable cylinder, - wherein the valve unit has a slide which can be slid from a closed to an open position of the valve unit by actuating the operating element inside the control unit, - wherein the control unit is designed in such a way that a self-holding valve function is achieved in which the lifting movement of the cylinder can be fully carried out upon only a single and/or brief actuation of the operating element, and - wherein the control unit can be connected to an end-position sensor of the cylinder such that the valve unit is closed when the end-position sensor is activated, - wherein the control unit has a sensor air inlet for connecting the end position sensor, wherein the valve unit is closed when there is a pressure increase and/or when a threshold pressure value of a sensor pressure at the sensor air inlet is exceeded, a magnet is arranged on the slide such that the slide is held in the open position of the valve unit by the holding force of the magnet in the open position, and the sensor air inlet is arranged such that a pressure applied thereto counteracts the holding force of the magnet, wherein to this end the sensor air inlet is connected to a closed valve chamber arranged between the housing of the control unit and the magnet.
