6.5 Status messages and diagnostic information
Operational faults in device
Messages on the display Description
Actions
Status: F _ _ _ _ _
Operational fault in device, mA output
≤
3.6 mA or set fault current (depending
on the seriousness of the fault), status
output open, pulse / frequency output:
no pulses
Repair necessary.
F error in device
Fault or failure of device. Parameter or
hardware error. No measurement possible.
Group message, when one of the following
or some other severe error occurs.
F IO 1
Error, operational fault in IO 1. Parameter
or hardware error. No measurement
possible.
Load settings (Fct. C4.6.3) (backup 1,
backup 2 or factory settings). If status
message still does not disappear, replace
electronic unit.
F parameter
Error, operational fault of data manager,
electronic unit, parameter or hardware
error. Parameters no longer usable.
F IO 2
Error, operational fault in IO 2. Parameter
or hardware error. No measurement
possible.
F configuration (also when
changing modules)
Invalid configuration: display software, bus
parameter or main software do not match
existing configuration. This error also
occurs when a module has been added or
removed without confirming the
configuration change.
After module change, confirm query for
changed configuration. If device
configuration unchanged: defective, replace
electronic unit.
F display
Error, operational fault in display.
Parameter or hardware error. No
measurement possible.
Defective, replace electronic unit.
F sensor electronic
Error, operational fault in measuring sensor
electronics. Parameter or hardware error.
No measurement possible.
Defective, replace electronic unit.
F sensor global
Data error in the global data of the
measuring sensor electronic equipment.
Load settings (Fct. C5.6.3) (backup 1,
backup 2 or factory settings). If status
message still does not disappear, replace
electronic unit.
F sensor local
Data error in the local data of the measuring
sensor electronic equipment.
Defective, replace electronic unit.
F field current local
Data error in the local data of the field
current supply
Defective, replace electronic unit.
F current in-/output A
Error, operational fault in current output or
output for terminals A/B. Parameter or
hardware error. No measurement possible.
Defect, replace electronic unit or
input/output module (I/O module).
F current in-/output B
F current output C
Error, operational fault in current output for
terminal C. Parameter or hardware error.
No measurement possible.
Defect, replace electronic unit or output
module (I/O module).
F software user interface
Fault revealed by CRC check of operation
software.
Replace electronic unit.
F hardware settings (also
when changing modules)
The set hardware parameters do not match
the identified hardware. A dialogue appears
in the display.
Answer queries in dialogue mode, follow
directions.
After module change, confirm query for
changed configuration. If device
configuration unchanged: defective, replace
electronic unit.
F hardware detection
Existing hardware cannot be identified.
Defective or unknown modules.
Replace electronic unit.
