Measures for Error Correction

9.2.2
Limit work on the hardware to the necessary extent.
NOTE

Defective modules can be replaced only by experienced persons. Never open modules yourself.
The following software measures are possible:
•
Initializing the system
•
If, for example, you would like to set a supervision function so that it becomes more insensitive since it is
responding sporadically in the operating state, change the parameterization.
NOTE

If these measures do not lead to the desired result, avoid further measures during operation.

Fallback Mode

9.2.3
If an error is detected in the device that cannot automatically be cleared (hardware components, software or
parameters), the device switches automatically into fallback mode. This can appear in system start or during
operation of the device. The fallback mode allows you a minimum procedure with error diagnosis and error
correction.
