Method of adjusting pneumatic devices

摘要

A method of adjusting pneumatic devices (1) from an actual value to a desired value is proposed. The devices have one or more adjusting screws which can be turned by computer-controlled motors (6). The method comprises the following steps: first of all, the actual value of the device is measured and stored; then the measured actual value is compared with a number of desired values stored in the computer (5), a constant number of degrees being allocated to each stored desired value. The adjustments are in each case selected in such a way that they lead to the desired value of the device. The direction of rotation is determined by a desired/actual value comparison. <IMAGE>
