9. Messages and diagnosis
The Type 3785 PROFIBUS PA Positioner provides the best possibilities for diagnosis during
the initialization process. In automatic mode, detailed tests are carried out to check and
evaluate the attachment situation and the positioner’s reaction, taking into account the preset
or entered data. When performing routine tests or in case of unclear diagnosis/error mess-
ages during operation, reinitialize the system to enable a better assessment of the controlled
system.
