Malfunctions
10.2 Error messages generated by the compact controller
Error messages saved in the error memory of the controller can be uploaded and read in
TROVIS-VIEW. The internal errors generated by the controller and errors that occurred
during a start-up adaptation are shown.
The existence of an error message is indicated by the Internal error data point in the 'Oper -
ation' and 'Start-up adaptation [TUNE]' folders.
If an error message (ERR) has been generated by the controller and it has been read out, a
temporary 'Error messages' folder containing the incoming error messages is created in the
'Operation' and 'Start-up adaptation [TUNE]' folders.
To clear the error messages in the controller, double-click the Reset all internal errors data
point in the 'Error messages' folder. Perform the reset during online data transmission to the
controller.
10.3 Emergency action
The control function no longer works after device failure. In this case, isolate and shut-off
valves.
Plant operators are responsible for emergency action to be taken in the plant.
Emergency action in the event of valve failure is described in the associated valve documen -
tation.
