Once Autoadjust has finished running without encountering any
errors, the device displays the message "RUN" in the bottom line
and a code number in the top line, indicating the step that is
currently being executed:
10 Air is completely evacuated from actuator (OUT1). The fully
evacuated position is saved.
20
Air is completely ventilated from actuator (OUT1). The fully
ventilated position is saved.
30 Determining stroke time is prepared.
31 Actuator travels from 0% to 100%, stroke time is measured
and saved.
32
Actuator travels from 100% to 0%, stroke time is measured
and saved.
40 to 49 Tolerance band is determined and saved (minimum value).
PD parameters for fast control < tolerance band is
determined and saved.
50 to 59 PID parameters for fast control < tolerance band is
determined and saved.
200 Automatic adjustment is complete.
In the case of a partial adjustment (see parameter DANG_DN
page 27) the following code numbers are displayed:
Stops only Steps 10 to 32 and Step 200
Parameters only
Steps 40 to 120 and Step 200
Zero only:
10 Air is completely evacuated from actuator (OUT1). The fully
evacuated position is saved.
200 Automatic adjustment is complete.

ZERO_POS Zero position only (configured stops required)
LOCKED No Autoadjust
TEST – Test
The test is used to activate the positioner, and you can check the
effects of the changes to this parameter group, e.g., by
introducing setpoint changes or setpoint ramps using a current
source.
Normally, INACTIVE is shown in the display. To start the test,
press and hold the ENTER button, until the countdown displayed
on it has run from 3 to 0 and finished. The test is activated. The
display shows the control loop symbol and a flashing message.
The test is automatically stopped after two minutes and can also
be stopped by pressing any button.
Note
The test cannot start with an active safety position (see
parameter FAIL_POS page 37). Instead, the message FAIL_POS is
displayed.
