The '52.XDIAG' Activating for extended diagnostics (Page 174)
parameter is set to 'On1', 'On2' or 'On3'.
• OFF
• On
Use this parameter to continuously monitor the number of changes
in direction of the actuator beyond the deadband. Monitoring is
performed in three steps. Set the following sub-parameters appro-
priately. To activate monitoring, set the parameter to 'On'. Sub-
parameters are displayed.
The current value is displayed in Diagnostic value '2.CHDIR -
Number of changes in direction' (Page 211). The positioner trig-
gers a message if the current value exceeds one of the three
thresholds.
OFF
1 ... 1.00E8
Use this sub-parameter to set the base limit for the changes of direction of the
actuator. Set the base limit in a range from '1' to '1.00E8'.
1.00E6
0.1 ... 40.0
Use this sub-parameter to set the factor for formation of threshold 1. Set the
factor in a range from '0.1' to '40.0'. The threshold is the product of 'O1.LIMIT'
and 'O2.FACT1'.
The threshold 1 message is displayed when threshold 1 is exceeded. The pro-
cess to activate and display this message is described in the 'XDIAG' parame-
ter.
