Start-up and conguration at the device
1. In manual mode, set the manipulated variable Y to the operating point so that the con-
trolled variable X has the same value as the set point W.
2. Raise the manipulated variable Y, for example by 10% (with step change value of the
manipulated variable Y.JMP = 20%) and wait until the controlled variable X does not
change anymore.
3. Check whether the controlled variable is within the permissible range.
4. Reduce the manipulated variable Y, for example by 20% (with step change value of the
manipulated variable Y.JMP = 20%) and wait until the controlled variable X does not
change anymore.
5. Check whether the controlled variable is within the permissible range.
6. In the TUNE menu, select -CO- ADAP function and set the step change value Y.JMP.
7. In the TUNE menu, select -CO- ADAP function. Select 'run ADP.S' to start the adaptation.
How long the adaptation takes is determined by the time behavior of the controlled sys-
tem. If the controlled variable does not reach an end value within ve hours, the adapta-
tion is automatically canceled.
After starting the adaptation, status messages on the start-up adaptation are displayed in the
top row.

Press key to cancel the adaptation.
If an error occurs during adaptation, the error appears on the display and the binary output
for fault alarms is activated (see the 'Malfunctions' section).
