Autotune 6:
PMO double seat valves with liftable lower valve disc
Autotune 6 is identical to Autotune 3, but with feedback fields for S1 changed in comparison to the factory set-
tings (see Chapter "6.8" on page 26): S1 ± 1.0 mm.
The feedback fields are already switched during the Autotune process. However, if the Autotune-6 process is
aborted (e.g. power failure) or is not successful, the feedback fields set previously are accepted again.
After a successful Autotune 6, the (
magnetic) manual control function is deactivated.
These settings made by Autotune 6 can be changed if required as follows:
• The magnetic manual control function can be re-activated
using PC software or via DeviceNet
only.
• The feedback fields changed by the Autotune function 6 can be changed to the original or another value
using
PC software or DeviceNet or by Feedback Field Mode
(see Chapter "16.3" on page 83).
• A
Device Reset
will also reset all settings made by the Autotune function 6 (comp. Chapter "6.9. Resetting the
device (Device Reset)" on page 28).
