Troubleshooting
6.1 Indication of Errors
A malfunction in the GRAPHIX Controller is displayed by an error message on the screen
or issued by an error number via the serial interface. Additionally, an entry is made into the
error memory list, from which the 20 most recently registered errors can be displayed on the
screen (

Chapter 6.2 Error Log, page 17) as well as read out via serial interface. The
following tables give a survey on all recognisable sensor errors (

Table 7, page 16) and
device errors (

Table 8, page 17).
