With multistage ratio control, the position values can be changed in 2 different ways:
1. Presetting the positions with no response by the actuators in order to fine-adjust the
points later using «Followed».
2. Setting the switching and operating positions from «below» using «Followed». This
means that stage 1 must be adjusted first, followed by the next switching on point,
etc.

When the switch on / off and operating positions have been parameterized with «Not fol-
lowed», the values can be changed. The system maintains its current load stage.
The menu offers the choice of «Followed» or «Not followed». The display is maintained
while the settings are made.
When accessing the menu, the operating positions «Stage 1» appear.
By pressing the Selection buttons the entered positions of all switching and operating
points can be viewed.
This has no impact on the system, even if «Followed» has been selected:
