Note
Height adjustment of the positioner
When you fasten the positioner on the yoke, the following applies to its height adjustment:
1. Set the height of the positioner in such a way that the horizontal lever position is near the
center of the stroke.
2. Orient yourself by the lever scale of the actuator.
3. If symmetrical mounting is not possible, you must always ensure that the horizontal lever
position is maintained within the range of stroke.
4.3 Mounting to part-turn actuator
Requirements
You require an actuator-specific VDI/VDE 3845 mount to install the positioner on a part-turn
actuator. Because of the high weight of the version in the flameproof stainless steel enclosure
6DR5..6, you should select a particularly stable mount.
