6.7.1 Error category "Device failure" (bold "F")
INFORMATION!
Regard that in case of an error message of the category "F
FF F" the measured values are not valid!
Messages on the display Description Actions
F F F F error in device Error or failure (breakdown) of the complete
device; parameter or hardware error;
measurement not possible.
Group message, when one of the following
or some other severe error occurs.
F F F F IO 1 Error or failure of corresponding IO;
parameter or hardware error;
measurement not possible.
Load settings (see C5.6.3: backup 1, backup
2 or factory settings). If status message still
does not disappear, replace electronic unit. F F F F IO 2
F F F F parameter Error or failure of data manager; parameter
or hardware error; measurement not
possible.
F F F F configuration Invalid configuration: display, software, bus
parameter or main software do not match
existing configuration.
This error message also appears if a
module has been added or removed, but
configuration has not been confirmed.
If device configuration has not been
changed, but message appears though:
replace electronic unit.
F F F F display Error or failure of the display; parameter or
hardware error; measurement not possible.
Replace electronic unit.
F F F F sensor electronic A
(or B)
Error or failure of the electronics of
sensor A (or B); parameter or hardware
error; measurement not possible.
Check sensor and connection; if both are
okay, replace the electronic unit.
F F F F sensor global A (or B) Data error in the global data of the
electronics of sensor A (or B);
measurement with the affected sensor not
possible.
Load settings (see C5.6.3: backup 1, backup
2 or factory settings). If status message still
does not disappear, replace electronic unit.
F F F F sensor local A (or B) Data error in the local data of the
electronics of sensor A (or B);
measurement with the affected sensor not
possible.
Replace electronic unit.
F F F F current output A (or B
or C)
Error or failure of the current output of
terminal A (or B or C); parameter or
hardware error; affected current output not
usable.
Check connection of current output; if it is
okay, replace the electronic unit.
F F F F software user interface Fault revealed by CRC check of operation
software.
Replace electronic unit.
F F F F hardware settings The set hardware parameters do not match
the identified hardware; a dialogue appears
in the display.
Answer queries in dialogue mode, follow
directions; replace defective electronic unit.
F F F F hardware detection Existing hardware cannot be identified;
modules are either unknown or defective.
Replace electronic unit.
