Fault codes
In case of unacceptable conditions in the system a fault code will be displayed.
Fault codes have been defined as follows:
FE 1: Measuring range has been exceeded
This fault code indicates that the measuring range of the A/D converter has been exceeded.
Potential fault cause:
transmitter damaged
short-circuit in transmitter connection
GIA0420WK not/incorrectly configurated
Remedies:
FE 1 will be reset as soon as the measuring values are back within their
permissible range. Please check your transmitter and transmitter
connecting cables.
FE 2: Measuring values have fallen below permissible range
This fault code indicates that the measuring values of the A/D converter have fallen below the
permissible range.
Potential fault cause:
transmitter damaged
transmitter connection interrupted
GIA0420WK not/incorrectly configurated
Remedies:
FE 2 will be reset as soon as the measuring values are back within their
permissible range. Please check your transmitter and transmitter
connecting cables.
FE 6: New Startup
This error message signals that the instrument is currently performing the startup sequence.
possible cause:
Input current to low
Remedies:
FE6 will be reset as soon as the instrument has finished its startup
sequence. Check the loop current.
