Suggested Action
Check calibration of AO2, AIN 3 and AIN4
(CM50 only).

Check invalid sources in diagnostics menu –
see Section 7.9, page 59. 
Check configuration, check I/O required for
configuration is present and correct any
illegal use of the invalid signal by changing
configuration or fitting additional option
cards.
Check process response. Consider if
Autotune dynamic setting should be
changed. Ensure process is stable and
repeat autotune. 
If problem persists tune the loop manually.
Check input wiring. Ensure process is stable
and repeat Autotune. 
If problem persists, tune the loop manually.
