Accessories

Very safe mounting and quick connection of the Pneumatics. Time-consuming installation is not necessary any more due to the integrated tube connections (push-in) which enable safe connection and quick insertion and removal without any Tools. On the electrical side the AirBox can be integrated very easily into the existing AS-i network by means of the supplied flat cable lower part. The AirBox no longer has to be screwed onto the lower part. Quick mounting technology with a slide ensures reliable connection between the AirBox and the flat cable lower part. The AirBox is supplied as usual via the AS-i cable or in addition by means of the black flat cable in order to be able to separately switch off the Pneumatic outputs of the Valves via e-stops. All AirBox versions also have a manual override. This allows the user to carry out a pneumatic function test of the AirBox initially, without connection to the AS-i network.

Safety at Work

Function Starting from the off position of the 3/2-way valve (see drawing) the feed of compressed air [P] to the single-acting cylinder is blocked when the valve (AirBox) is connected to the compressed air supply. The piston rod of the cylinder can be moved in any direction. If the respective output of the AirBox is triggered via AS-i and thus the valve is operated (via the pilot valve, solenoid, squares are moved one position to the right, see drawing) the feed of compressed air to the cylinder is released and the piston rod of the cylinder is extended. By resetting the output the valve is pressed back into the off position by means of the return spring. The piston rod of the cylinder retracts.
