To start the automatic adjustment, press and hold ENTER
until the countdown from 3 to 0 is finished. During the
countdown, the automatic adjust ment mode selected using
parameter ADJ_MODE is shown on the display. While
Autoadjust is running, the control loop symbol flashes in the
display, and the current state of Autoadjust is indicated with
the messages listed below.
(No acknowledgment)
NOTE
All messages except "RUN" mu st be acknowledged with
ENTER .
(Acknowledgment required)
RUN
Autoadjust is running.
CALC_ERR
Error during plau sibility check.
COMPLETE
Autoadjust completed successfully.
BREAK
Autoadjust has been stopped by the operator. This can
be done locally by pressing ENTER .
OUTOFRNG
Sensor range of the positioner has been exceeded;
Autoadjust was stopped.
NO_SCALE
End positions have not yet been determined; therefore,
partial Autoadjust cannot be run
RNG_ERR
Less than 10% of the sensor range is used.
TIMEOUT
Timeout. The control parameters could not be
determined within 200 second s. Automatic adjustment
was stopped.
SPR_ERR
The actual spring action does not match the configured
spring action
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 - 49
Tolerance band is determined and saved (minimum
value). PD parameters for fast control < tolerance band
is determined and saved.
50 - 59
PID parameters for fast control < tolerance band is
determined and saved.
200
Automatic adjustment is complete.
If a partial run of automatic adjustment has been selected (see
parameter DANG_DN on page 23), the following code
numbers are shown:
Stops only
Steps 10 … 32 and step 200
Parameters only
Steps 40 … 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.

Adjust function.
FULL
Complete Autoadjust
STROKE
