In the normal operating state, a function without jerk provides the set values for an underlying position control loop. Moving the electrodes however with the drives within a narrow tank can be very challenging. For installation and service, we need a manual control facility, which allows to steer the mobile drive rods slowly to the electrodes. Hence eight hand wheels, one at each drive, will make manual positioning of each. A bus-shaped network from several wheel-controllers to a central computer was implemented. A smooth and data saving transmission can be achieved by applying approved techniques from real time data processing. The equipment of analogue drive systems with digital regulation and controls allows to change the proportion between drive distance and angle of rotation of a hand wheel only by means of software.
