P3.LEVL1 - threshold 1
Possible settings: 0.1 ... 100.0
Purpose: Use this sub-parameter to set threshold 1 for the maximum devia‐
tion of the current average value of position from the average value
of reference. The value is given in percent. Set the threshold in a
range from '0.1' to '100.0'.
The positioner triggers the threshold 1 message if the difference
between the average value of position and the average value of
reference exceeds threshold 1. This message is only output if
threshold 2 or 3 is not exceeded at the same time. The process to
activate and display this message is described in the 'XDIAG' pa‐
rameter.
Factory setting: 2.0
P4.LEVL2 - threshold 2
Possible settings: 0.1 ... 100.0
Purpose: Use this sub-parameter to set threshold 2 for the maximum devia‐
tion of the current average value of position from the average value
of reference. The value is given in percent. Set the threshold in a
range from '0.1' to '100.0'.
The positioner triggers the threshold 2 message if the difference
between the average value of position and the average value of
reference exceeds threshold 2. This message is only output if
threshold 3 is not exceeded at the same time. The process to acti‐
vate and display this message is described in the 'XDIAG' param‐
eter.
Factory setting: 5.0
P5.LEVL3 - threshold 3
Possible settings: 0.1 ... 100.0
Purpose: Use this sub-parameter to set threshold 3 for the maximum devia‐
tion of the current average value of position from the average value
of reference. The value is given in percent. Set the threshold in a
range from '0.1' to '100.0'.
The positioner triggers the threshold 3 message if the difference
between the average value of position and the average value of
reference exceeds threshold 3. The process to activate and display
this message is described in the 'XDIAG' parameter.
Factory setting: 10.0
