The '52.XDIAG' Activating for extended diagnostics (Page 166) pa‐
rameter is set to 'On'.
The '34.DEBA' Deadband of closed-loop controller (Page 154) pa‐
rameter is set to 'Auto'.
● OFF
● On
Use this parameter to continuously monitor the automatic adaptation
of the deadband. Monitoring is performed in one step. To activate
monitoring, set the parameter to 'On'. The sub-parameter is dis‐
played. Appropriately set the sub-parameter.
The current value is displayed in Diagnostic value '26.DBUP - Dead‐
band up' / '27.DBDN - Deadband down' (Page 209). The positioner
triggers a message if the current value exceeds the threshold.
OFF
0.1 ... 10.0
Use this sub-parameter to set the threshold to the deadband in per‐
cent. Set the threshold in a range from '0.1' to '2.9'. The values are
monitored in the range of '0.1' to '2.9'. Values between '3.0' and '10.0'
are not monitored.
The threshold 3 message is displayed when the current deadband
exceeds the threshold during the test. The process to activate and
display this message is described in the 'XDIAG' parameter.
