EXIT – Back to work level
With this parameter you can leave the configuration level. The
positioner returns to the operating level. Here you can either
save data in the non-volatile memory or discard all previously
made changes (also the changes in other parameter groups).
To exit the configuration level (with or without saving), press
and hold the ENTER button, until the countdown has run from 3
to 0 and finished.
The active saving process is indicated by the message NV_SAVE.
After saving a plausibility check is executed.
If an error occurs during the check or while saving, the data
cannot be saved and an error message is displayed instead (see
Chapter Error codes on page 40).
Selection
NV_SAVE Saves settings in the non-volatile memory.
CANCEL Discards all changes made since the last permanent
save operation.

Parameter group 7: Controller parameters

KP UP – KP value (up)
Note
In the case of most actuators, all control parameters can be
optimized by using Auto Adjust. Changes should only be made
when auto adjust cannot be executed or control stability cannot
be achieved.
The KP value is the gain of the controller. The control speed and
stability are influenced by the KP value. With higher KP values,
the control speed increases.
Note
The control precision is not affected by the KP value.
To compensate for existing dissymmetries in the controlled
system, the KP value should be set separately for both
positioning directions (up / down).
For most actuators, satisfactory control behavior is achieved
with a KP value between 2.0 and 10.0.
Use the KP UP parameter to adjust the KP value for the up
positioning direction (towards 100 %).
